+# ArkUI Development (ArkTS Syntax)
+
+## How do I dynamically create components using code in ArkUI?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+ArkUI uses the ArkTS declarative development paradigm. Developers cannot hold component instances. During declaration, you can control component creation by rendering control syntax and dynamically building UI elements.
+
+**Example**
+
+```
+// Create a component using the if statement.
+if(this.isTrue) {
+  Text ("Create Text Component").fontSize (30)
+}
+// Create a component using the ForEach statement.
+ForEach(this.nums,(item) => {
+  Text(item + '').fontSize(30)
+},item => JSON.stringify(item))
+```

+
+## What is the difference between an @Builder decorated method and a regular method?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+The @Builder decorated method allows for use of a custom component, while regular methods do not. If a custom component is used in an @Builder decorated method, it is re-created each time the method is called.
+
+**Reference**
+
+[@BuilderParam](../quick-start/arkts-builderparam.md)
+
+## How do I define @BuilderParam decorated attributes?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+-   Without parameters
+
+    If no parameter is passed when assigning a value to the **@BuilderParam** decorated attribute (for example, **content: this.specificParam**), define the type of the attribute as a function without a return value (for example, **@BuilderParam content: \(\) =\> void**).
+
+-   With parameters
+
+    If any parameter is passed when assigning a value to the **@BuilderParam** decorated attribute (for example, **callContent: this.specificParam1\("111"\)**), define the type of the attribute as **any** (for example, **@BuilderParam callContent: any**).

+
+## How do I listen for object changes in an array?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+To listen for object changes in an array, use the @Observed and @ObjectLink decorators. **@Observed** applies to classes, and **@ObjectLink** applies to variables.
+
+**Example**
+
+1.  Use @Observed on a class.
+
+    ```
+    @Observed
+    class ClassA {
+      public name: string
+      public c: number
+      public id: number
+    
+      constructor(c: number, name: string = 'OK') {
+        this.name = name
+        this.c = c
+      }
+    }
+    ```
+
+2.  Use @ObjectLink on a component variable.
+
+    ```
+    @Component
+    struct ViewA {
+      label: string = 'ViewA1'
+      @ObjectLink a: ClassA
+    
+      build() {
+        Row() {
+          Button(`ViewA [${this.label}] this.a.c= ${this.a.c} +1`)
+            .onClick(() => {
+              this.a.c += 1
+            })
+        }.margin({ top: 10 })
+      }
+    }
+    ```
+

+
+## How do I transfer values through the parent component to @Link decorated varaibles in a child component?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+To enable a child component to receive the value from the parent component through @Link, '**\$**' must be used to first establish a reference relationship between variables in the child and parent components.  
+
+**Example**
+
+The **@Link** semantics are derived from the '**$**' operator. In other words, **\$isPlaying** is the two-way binding of the internal state **this.isPlaying**. When the button in the **PlayButton** child component is touched, the value of the @Link decorated variable is changed, and **PlayButton** together with the **\<Image>** and **\<Text>** components of the parent component is refreshed. Similarly, when the button in the parent component is touched, the value of **this.isPlaying** is changed, and **PlayButton** together with the **\<Text>** and **\<Button>** components of the parent component is refreshed.
+
+1.  Use the @State decorator in the parent component and use the '**\$**' operator to create a reference for transferring data.
+
+    ```
+    @Entry
+    @Component
+    struct Player {
+      @State isPlaying: boolean = false
+      build() {
+        Column() {
+          PlayButton({ buttonPlaying: $isPlaying })
+          Text(`Player is ${this.isPlaying ? '' : 'not'} playing`).fontSize(18)
+          Button('Parent:' + this.isPlaying)
+            .margin(15)
+            .onClick(() => {
+              this.isPlaying = !this.isPlaying
+            })
+        }
+      }
+    }
+    
+    
+    ```
+
+2.  Use @Link in the child component to receive data.
+
+    ```
+    @Component
+    struct PlayButton {
+      @Link buttonPlaying: boolean
+    
+      build() {
+        Column() {
+          Button(this.buttonPlaying ? 'pause' : 'play')
+            .margin(20)
+            .onClick(() => {
+              this.buttonPlaying = !this.buttonPlaying
+            })
+        }
+      }
+    }
+    ```

+## How does a component synchronize state with its grandchild components?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+-   Method 1 (recommended): Use the @Provide and @Consume decorators. Specifically, use @Provide in the component and @Consume in the grandchild component to implement two-way data binding between the components.
+
+-   Method 2: Use the @State and @Link decorators. Specifically, use @State in the parent component and @Link in each layer of child components (child and grandchild components).
+
+**Example 1**
+
+1.  Include a child component in the component. Employ @Provide in the component to provide the **reviewVote** parameter to its grandchild component.
+
+    ```
+    @Entry
+    @Component
+    struct Father{
+      @Provide("reviewVote") reviewVotes: number = 0;
+    
+      build() {
+        Column() {
+          Son()
+          Button(`Father: ${this.reviewVotes}`)
+            ...
+        }
+      }
+    }
+    ```
+
+2.  Include the grandchild component in the child component.
+
+    ```
+    @Component
+    struct Son{
+      build() {
+        Column() {
+          GrandSon()
+        }
+      }
+    }
+    ```
+
+3.  Employ @Consume in the grandchild component to receive the **reviewVote** parameter.
+
+    ```
+    @Component
+    struct GrandSon{
+      @Consume("reviewVote") reviewVotes: number
+    
+      build() {
+        Column() {
+          Button(`GrandSon: ${this.reviewVotes}`)
+            ...
+        }.width('100%')
+      }
+    }
+    ```
+
+
+**Example 2**
+
+1.  Employ @State in the component **Father** to decorate **reviewVote**.
+
+    ```
+    @Entry
+    @Component
+    struct Father {
+      @State reviewVotes: number = 0;
+    
+      build() {
+        Column() {
+          Son({reviewVotes:$reviewVotes})
+          Button(`Father: ${this.reviewVotes}`)
+            ...
+        }
+      }
+    }
+    ```
+
+2.  Employ @Link in the child component **Son** to receive the **reviewVote** parameter passed from **Father**.
+
+    ```
+    @Component
+    struct Son{
+      @Link reviewVotes: number;
+      build() {
+        Column() {
+          Grandson({reviewVotes:$reviewVotes})
+        }
+      }
+    }
+    
+    
+    ```
+
+3.  Employ @Link in the grandchild component **GrandSon** to receive the **reviewVote** parameter passed from **Son**.
+
+    ```
+    @Component
+    struct Grandson{
+      @Link reviewVotes: number;
+    
+      build() {
+        Column() {
+          Button(`Grandson: ${this.reviewVotes}`)
+            ...
+        }.width('100%')
+      }
+    }
+    ```
+
+
+## How is a callback function defined in JS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+The following is an example to illustrate how to define a callback function:
+
+1.  Define the callback function.
+
+    ```
+    // Define a callback function that contains two parameters and returns void.
+    myCallback: (a:number,b:string) => void
+    ```
+
+2.  Initialize the callback function by assigning values.
+
+    ```
+    aboutToAppear() {
+      // Initialize the callback function.
+      this.myCallback= (a,b)=>{
+        console.info(`handle myCallback a=${a},b=${b}`)
+      }}
+    ```
+
+
+## How do I maximize performance in cases when a component needs to be updated for multiple times?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Use the state management module for the purpose. Currently, the minimum update is supported. When the data dependency changes, instead of updating the entire custom component, only the view content that depends on the data is updated.
+
+## How does this of a function in an object point to the outer layer?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+You can use the arrow function for this purpose.
+
+**Example**
+
+```
+const obj = {
+  start:() => {
+    return this.num
+  }
+}
+```
+
+## How do I obtain data through an API before page loading?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+Data needs to be obtained before page rendering so as to be rendered when needed.
+
+**Solution**
+
+In the **aboutToAppear** function, use an asynchronous API to obtain page data and @State to decorate related variables. After the data is obtained, the page is automatically refreshed based on the variables.
+
+**Example**
+
+```
+@Entry
+@Component
+struct Test6Page {
+  // After the data is obtained, the page is automatically refreshed.
+  @State message: string = 'loading.....'
+  aboutToAppear(){
+    // Simulate an asynchronous API to obtain data.
+    setTimeout(()=>{
+      this.message = 'new msg'
+    },3000)
+  }
+  build() {
+    Row() {
+      Column() {
+        Text(this.message)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+
+## How do I display sensor data in the \<Text> component on the UI in real time?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+The type of data returned by the sensor is double. To display it in the \<Text> component, first convert the data from double to string.
+
+## How do I listen for screen rotation events?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+To listen for screen rotation events, use the **mediaquery** API.
+
+```
+import mediaquery from '@ohos.mediaquery'
+let listener = mediaquery.matchMediaSync('(orientation: landscape)'); // Listen for landscape events.
+function onPortrait(mediaQueryResult) {
+  if (mediaQueryResult.matches) {
+   // do something here
+  } else {
+   // do something here
+  }
+}
+listener.on('change', onPortrait) // Register a callback.
+listener.off('change', onPortrait) // Deregister a callback.
+```
+
+**Reference**
+
+[@ohos.mediaquery (Media Query)](../reference/apis/js-apis-mediaquery.md)
+
+## What should I do if a singleton does not take effect after the page is changed?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+A singleton works only in the same page. It becomes **undefined** when the page changes.
+
+**Solution**
+
+A JS file is generated for each page, and a defined singleton is generated in each JS file. Therefore, the singleton in applicable only to the owning page.
+
+To share an instance across pages, it must be created at the UIAbility or application level.
+
+## How do I convert a string in time format to a date object?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+If the string is in the yyyy-MM-dd format, you can convert it to a date object by calling **new Date\("yyyy-MM-dd"\)**.
+
+```
+new Date("2021-05-23");
+new Date("2020/2/29");
+new Date("2020-14-03");
+new Date("14-02-2021");
+```
+
+If the string is in other formats, you can convert it to a date object by calling **new Date\(year:number,month:number,day?:number,hour?:number,minute?:number,second?:number,ms?:number\)**.
+
+```
+// Syntax for creating a date based on parameters:
+new Date(yearValue, IndexOfMonth, dayValue, hours, minutes, seconds)
+```
+
+Pass the date parameters as arguments.
+
+-   **yearValue**: the year in the ISO 8061 YYYY format, for example, **2021**. If we specify a value in YY format, it will be incorrectly accepted. For example, the value **21** would be considered the year 1921 rather than 2021.
+-   **IndexOfMonth**: index of the month, which starts from 0. It is obtained by subtracting 1 from the month value. For example, for March, the month value is 3, but the value of **IndexOfMonth** will be 2 (that is, 3 – 1 = 2). The value should typically be within the 0–11 range.
+-   **dayValue**: day of the month. It should range from 1 to 31 depending on the number of days in the month. For example, for 21-05-2021, the day value is **21**.
+-   **hours**: hour of the day. For example, **10** for 10 o'clock.
+-   **minutes**: number of minutes that have elapsed in the hour.
+-   **seconds**: number of seconds past a minute.
+
+## How do I convert a string to a byte array in ArkTS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Refer to the following code:
+
+```
+stringToArray(str:string) {
+  var arr = [];
+  for(var i = 0,j = str.length;i<j;++i) {
+ arr.push(str.charCodeAt(i))
+  }
+  return arr;
+}
+```
+
+## How do I implement string encoding and decoding in ArkTS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+You can use **TextEncoder** and **TextDecoder** provided by the **util** module.
+
+**Reference**
+
+[TextEncoder](../reference/apis/js-apis-util.md#textencoder), [TextDecoder](../reference/apis/js-apis-util.md#textdecoder)
+
+## How do I import and export namespaces?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Use **import** and **export** statements.
+
+-   Exporting namespaces from the database:
+
+    ```
+    namespace Util{
+        export function getTime(){
+            return Date.now()
+        }
+    }
+    export default Util
+    ```
+
+-   Importing namespaces
+
+    ```
+    import Util from './util'
+    Util.getTime()
+    ```
+
+## Can relational database operations be performed in the Worker thread?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+Currently, the relational database (RDB) object in the UI main thread cannot be sent to the Worker thread for operations. To use the RDB in the Worker thread, you must obtain a new RDB object.
+
+## How do I obtain files in the resource directory of an application?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+-   Method 1: Use **\$r** or **\$rawfile**. This method applies to static access, during which the **resource** directory remains unchanged when the application is running.
+-   Method 2: Use **ResourceManager**. This method applies to dynamic access, during which the **resource** directory dynamically changes when the application is running.
+
+**Reference**
+
+[Resource Categories and Access](../quick-start/resource-categories-and-access.md) and [@ohos.resourceManager (Resource Manager)](../reference/apis/js-apis-resource-manager.md#getstring)
+
+## How do I convert the XML format to the JSON format?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+The data returned by the server is encoded using Base64 in XML format and needs to be converted to the JSON format for subsequent processing.
+
+**Solution**
+
+Use the Base64-related APIs in the **util** module to decode data, and then use the **convertxml** module to parse data in XML format.
+
+**Example**
+
+```
+import convertxml from '@ohos.convertxml';
+import util from '@ohos.util';
+
+@Entry
+@Component
+struct Faq_4_31 {
+  @State message: string = 'base64 to JSON'

+## What are the restrictions on using generator functions in TypeScript?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Below are the restrictions on using generator functions in TypeScript:
+
+-   Expressions can be used only in character strings (in the \(\$\{expression\}\) format), **if** conditions, **ForEach** parameters, and component parameters.
+-   No expressions should cause any application state variables (**@State**, **@Link**, and **@Prop**) to change. Otherwise, undefined and potentially unstable framework behavior may occur.
+-   The generator function cannot contain local variables.
+
+None of the above restrictions apply to anonymous function implementations of event handlers (such as **onClick**).
+
+## How do I set a badge for each of the four corners of an image?
+
+Applicable to: OpenHarmony 3.2 Beta5
+
+**Solution**
+
+You can use absolute positioning to set the offset of the element anchor relative to the top start point of the parent container. In the layout container, setting this attribute does not affect the layout of the parent container.
+
+**Example**
+
+```
+@Entry
+@Component
+struct PositionExample2 {
+  build() {
+    Column({ space: 20 }) {
+      Stack({ alignContent: Alignment.TopStart }) {
+        Row()
+          .size({ width: '100', height: '100' })
+          .backgroundColor(0xdeb887)
+        Image($r('app.media.app_icon'))
+          .size({ width: 25, height: 25 })
+          .markAnchor({ x: 0, y: 0 })
+        Image($r('app.media.app_icon'))
+          .size({ width: 25, height: 25 })
+          .markAnchor({ x: 25, y: 25 })
+          .position({ x: '100%', y: '100%' }) 
+      }.margin({ top: 25 }).width('100').height('100')
+    }
+    .width('100%').margin({ top: 25 })
+  }
+}
+```
+
+## How do I use the util.generateRandomUUID parameter?
+
+Applicable to: OpenHarmony 3.2 Beta5
+
+**Solution**
+
+The bottom layer of **generateRandomUUID** uses the **Node.js crypto.randomUUID\(\)** API. If the parameter passed in is **false**, a new UUID is generated and cached in the system. If the parameter passed in is **true**, the existing cached UUID is used.

+## Do the Worker thread and the main thread run in the same global context?
+
+Applicable to: OpenHarmony 3.2 Beta5
+
+**Solution**
+
+No. The Worker thread and the main thread are not in the same context. They interact with each other in data communication mode.
+
+**Reference**
+

+
+## How do I set one application icon for different device types?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+To configure your application icon to show on different device types, use resource qualifiers.
+
+**Example**
+
+1. Create a resource directory and add resource files to the directory. In this example, a **tablet** resource directory is created in **src/main/resources** and a **media** resource folder in the **tablet** directory.
+
+```
+├─base
+│  ├─element
+│  ├─media
+│  └─profile
+├─rawfile
+├─tablet
+│  ├─element
+│  └─media
+```
+
+2. Add the icon file to be displayed when the device type is tablet to the **media** folder. Reference the icon file on the UI.
+
+```
+@Entry @Component struct Index { build() {
+   Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
+     Text($r("app.string.my_string"))
+       .fontSize($r("app.float.my_float"))
+       .fontColor($r("app.color.my_color"))
+     Image($r("app.media.my_image"))
+       .width(100)
+       .height(100)
+   }
+   .width('100%')
+   .height('100%') } }
+```
+
+## How do I prevent "this" in a method from changing to "undefined" when the method is called?
+
+Applicable to: OpenHarmony 3.2 (API version 9)
+
+**Solution**
+
+Method 1: Add **.bind\(this\)** when calling the method.
+
+Method 2: Use the arrow function.
+
+## Is there any difference between the systemTime.getCurrentTime\(\) API of OpenHarmony and the new Date\(\).getTime\(\) API of JS?
+
+Applicable to: OpenHarmony 3.2 (API version 9)
+
+**Solution**
+
+**systemTime.getCurrentTime\(false\)** is equivalent to **new Date\(\).getTime\(\)**, returning the number of milliseconds since January 1, 1970. **systemTime.getCurrentTime\(true\)** returns the number of nanoseconds since January 1, 1970. The system time is used in both APIs.
+
+## How do I implement the ArkTS counterpart of the JS slot feature?
+
+Applicable to: OpenHarmony 3.2 (API version 9)
+
+**Solution**
+
+Applicable to: OpenHarmony SDK 3.2.5.5, stage model of API version 9
+
+Use @Build and @BuilderParam in ArkTS.
+
+**Reference**
+
+[\@BuilderParam: @Builder Function Reference](../quick-start/arkts-builderparam.md).
+
+## Why is the text not centered vertically when lineHeight is set?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Cause**
+
+Text in the **\<Text>** component is centered by default. You do not need to set the **lineHeight** attribute. As the text is drawn from the bottom, an appropriate line height can have the text centered. However, if the line height is too large, the text appears aligned toward the bottom. In general cases, use the **lineHeight** attribute together with the **padding** attribute to adjust the line spacing.

+
+## How do I set the controlButton attribute for the \<SideBarContainer> component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+The sample code is as follows:
+
+```
+@Entry
+@Component
+struct SideBarContainerExample {
+  normalIcon : Resource = $r("app.media.icon")
+  selectedIcon: Resource = $r("app.media.icon")

+
+## How do I implement the dragging feature for the \<Grid> component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+1.  Set the **editMode\(true\)** attribute of the **\<Grid>** component to specify whether the component enters the editing mode. In the editing mode, you can drag grid items.
+2.  Set the image displayed during dragging in the [onItemDragStart](../reference/arkui-ts/ts-container-grid.md#events) callback.
+3.  Obtain the drag start position and drag insertion position from the [onItemDrop](../reference/arkui-ts/ts-container-grid.md#events) callback, and complete the array position exchange logic in the [onDrag](../reference/arkui-ts/ts-universal-events-drag-drop.md#events) callback. The sample code is as follows:
+
+    ```
+    @Entry
+    @Component
+    struct GridExample {
+      @State numbers: String[] = []
+      scroller: Scroller = new Scroller()

+## Which API is used for URL encoding?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+Use the global function **encodeURI** for encoding and **decodeURI** for decoding. For example, the space character ""is encoded as %20.

+
+## How do I parse XML files?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)

+## What should I do if the .stateStyles doesn't conform standard error is reported with the use of the @Styles decorator?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Cause**
+
+The @Styles decorator is used for non-universal attributes.
+
+**Solution**
+
+Use the @Styles decorator only for non-universal attributes. Alternatively, use Builder to extract common components.
+
+## How do I use \$\$ for the \<Radio> component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+When the **\<Radio>** component uses a variable bound to **\$\$**, changes to the variable trigger re-render of only the owning component, improving the rendering speed.
+
+When the state of the **\<Radio>** component changes, the bound variable is not automatically updated.

+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Symptom**
+
+**ForEach** works in the previewer, but not on a real device.
+
+**Cause**
+
+If the system version on the real device is 3.2 beta5 or later, the minimum update policy is enabled by default.

+## How does the return result of onUrlLoadIntercept affect onInterceptRequest in the \<Web> component?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+The operation that follows **onUrlLoadIntercept** is subject to its return result.
+
+-   If **true** is returned, the URL request is intercepted.
+-   If **false** is returned , the **onInterceptRequest** callback is performed.

+## What should I do if the onKeyEvent event of the \<Web> component is not triggered as expected?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Problem**
+
+The **onKeyEvent** event is set for the **\<Web>** component to listen for keyboard events. However, it is not triggered when a key is pressed or lifted.
+
+**Solution**
+
+Currently, the **\<Web>** component does not support the **onKeyEvent** event. To listen for keyboard events for the **\<Web>** component, you can use the **onInterceptKeyEvent** callback function.

+## What should I do if page loading fails when onInterceptRequest is used to intercept URLs and return the custom HTML file?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Problem**
+
+The **onInterceptRequest** API intercepts URLs specified by **src** and returns the custom HTML file. However, the content in the **script** tag in the HTML file is not loaded.
+
+**Solution**
+
+If only **setResponseData** is set for the interceptor, the kernel cannot identify the HTML file. You must also set parameters such as **setResponseEncoding**, **setResponseMimeType**, and **setResponseHeader** for the kernel to identify the HTML file.
+
+**Example**
+
+```
+Web({ src: 'www.example.com', controller: this.controller })
+  .onInterceptRequest((event) => {
+    console.log('url:' + event.request.getRequestUrl())
+    this.responseweb = new WebResourceResponse();

+    ```
+
+2.  Use the **JavaScriptProxy** API in ArkTs to register the object in ArkTS with the window object of H5, and then use the window object to call the method in H5. In the following example, the **testObj** object in ArkTS is registered with the window object of H5 with the alias **objName**. In H5, **window.objName** can then be used to access the object.

+## How do I set the domStorageAccess attribute of the \<Web> component?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+The **domStorageAccess** attribute sets whether to enable the DOM Storage API. By default, this feature is disabled.

+## What should I do if the network status fails to be detected on the HTML page loaded by the \<Web> component?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Problem**
+
+When **window.navigator.onLine** is used on the HTML page to obtain the network status, the value is **false** no matter the network connection is set up or not.
+
+**Solution**
+
+Configure the permission for the application to obtain network information: **ohos.permission.GET\_NETWORK\_INFO**.

+
+## How do I set the UserAgent parameter through string concatenation?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+By default, the value of **UserAgent** needs to be obtained through the WebviewController. Specifically, it is obtained by calling the **getUserAgent** API in a **WebviewController** object after it is bound to the **\<Web>** component. Therefore, to set **UserAgent** through string concatenation before page loading:
+
+1.  Use @State to define the initial **UserAgent** parameter and bind it to the **\<Web>** component.
+2.  In the **onUrlLoadIntercept** callback of the **\<Web>** component, use **WebviewController.getUserAgent\(\)** to obtain the default **UserAgent** value and update the UserAgent bound to the **\<Web>** component.
+
+**Example**
+
+```
+import web_webview from '@ohos.web.webview'
+@Entry
+@Component
+struct Index {
+  private controller: web_webview.WebviewController = new web_webview.WebviewController()
+  @State userAgentPa: string = ''
+  build() {
+    Row() {
+      Column() {
+        Web({ src: 'http://www.example.com', controller: this.controller }) // Replace the URL with the actual URL.
+          .width('100%')
+          .userAgent(this.userAgentPa)
+          .onUrlLoadIntercept((event) => {
+            let userAgent = this.controller.getUserAgent();
+            this.userAgentPa = userAgent + ' 111111111'
+            return false;
+          })
+      }

+
+## How do I enable the \<Web> component to return to the previous web page following a swipe gesture?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Override the **onBackPress** API to define the return logic and use **WebviewController** to determine whether to return to the previous web page.
+
+**Example**
+
+```
+import web_webview from '@ohos.web.webview';
+@Entry
+@Component
+struct Index {
+  controller: web_webview.WebviewController = new web_webview.WebviewController();
+  build() {
+    Column() {

+    }
+  }
+  onBackPress() {
+    // Check whether a specific number of steps forward or backward can be performed on the current page. A positive number indicates forward, and a negative number indicates backward.
+    if (this.controller.accessStep(-1)) {
+      this.controller.backward(); // Return to the previous web page.
+      // Execute the custom return logic.
+      return true
+    } else {
+      // Execute the default return logic to return to the previous page.

+## How do I dynamically replace the %s placeholder in a resource file?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+How do I dynamically replace the %s placeholder in a resource file?
+
+**Solution**
+
+In an application, you can replace the **%s** placeholder by using the second parameter in **$r('app.string.xx')**, which is used to reference application resources.
+
+**Example**
+
+```
+build() {
+  //do something
+  // The second parameter indicates the referenced string resource, which can be used to replace the %s placeholder.
+  Text($r('app.string.entry_desc','aaa')) 
+    .fontSize(100)
+    .fontColor(Color.Black)
+  //do something

+## Can custom dialog boxes be defined or used in .ts files?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+Unfortunately, no. ArkTS syntax is required for defining and initializing custom dialog boxes. Therefore, they can be defined and used only in .ets files.
+
+**Reference**
+
+[Custom Dialog Box](../reference/arkui-ts/ts-methods-custom-dialog-box.md)
+
+## How do I transfer variables in a custom dialog box to a page?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+The variable defined in a custom dialog box needs to be transferred to the page when the dialog box is closed or the variable changes.
+
+**Solution**
+
+-   Method 1: Define the variable as a state variable of the custom dialog box.
+-   Method 2: During initialization of the custom dialog box, pass to it a method, which is triggered in the custom dialog box and accepts the variable in the custom dialog box as a parameter.
+-   Method 3: Use AppStorage or LocalStorage to manage page state and implement state sharing between the custom dialog box and page.
+
+**Example**
+
+-   Method 1:
+
+    ```
+    @CustomDialog
+    struct CustomDialog01 {
+      @Link inputValue: string
+      controller: CustomDialogController

+
+## How do I obtain the width and height of a component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+The width and height of a component need to be obtained to calculate the size and offset of the layout area.
+
+**Solution**
+
+-   Method 1: Use the **onAreaChange** event of the component, which is triggered when the component is initialized or the component size changes.
+-   Manner 2: Use the callback in the click or touch event, which provides the area information of the target element.
+
+**Reference**
+
+[Component Area Change Event](../reference/arkui-ts/ts-universal-component-area-change-event.md), [Click Event](../reference/arkui-ts/ts-universal-events-click.md), [Touch Event](../reference/arkui-ts/ts-universal-events-touch.md)
+
+## How do I clear the content of the \<TextInput> and \<TextArea> components by one click?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+A click-to-clear feature is required to remove all characters in the **\<TextInput>** and **\<TextArea>** component at once.
+
+**Solution**
+
+Convert the **text** attribute of the **\<TextInput>** and **\<TextArea>** component to a state variable. Assign an empty string to the state variable when the click-to-clear event is performed.
+
+**Example**
+
+```
+struct Index {
+@State text: string = 'Hello World'
+controller: TextInputController = new TextInputController()
+  build() {
+    Row() {
+      Column() {
+        TextInput({ placeholder: 'Please input your words.', text: this.text,
+          controller:this.controller}).onChange((value) => {
+            this.text = value
+          })
+        Button("Clear TextInput").onClick(() => {
+          this.text = "";
+        })
+      }
+      .width('100%')
+    }

+  }
+}
+```
+
+## How do I set the position of a custom dialog box?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+By default, a custom dialog box is displayed in the center of the window. In some cases, it needs to be aligned with the window border.
+
+**Solution**
+
+During initialization of the custom dialog box, set the **alignment** and **offset** parameters.
+
+**Reference**
+
+[Custom Dialog Box](../reference/arkui-ts/ts-methods-custom-dialog-box.md)
+
+## How do I hide the overflow content of a container component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+When content overflows in a container component, that is, the child component does not fit in the container component, the overflow content needs to be processed.
+
+**Solution**
+
+To clip and hide overflow content, set the **clip** universal attribute to **true**. By default, this attribute is set to **false**.
+
+**Reference**
+
+[Shape Clipping](../reference/arkui-ts/ts-universal-attributes-sharp-clipping.md)
+
+
+## How do I set a custom dialog box to automatically adapt its size to content?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+When a custom dialog box contains a child component whose area size can be changed, it needs to automatically adjust its size.
+
+**Solution**
+
+-   Method 1: Use the default style of the custom dialog box. In this case, the dialog box automatically adapts its width to the grid system and its height to the child components; the maximum height is 90% of the container height.
+-   Method 2: Use a custom style of the custom dialog box. In this case, the dialog box automatically adapts its width and height to the child components.
+
+**Reference**
+
+[Custom Dialog Box](../reference/arkui-ts/ts-methods-custom-dialog-box.md)
+
+## What is the function of the gridCount parameter in the custom dialog box?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+The **gridCount** parameter indicates the number of grid columns occupied by the dialog box. The system divides the window width into equal regions. The number of equal regions is the number of grid columns, which varies by device. For example, if the screen density of a phone is 320 vp <= horizontal width < 600 vp, the number of grid columns is 4, and the valid value of **gridCount** is \[1, 4\].
+
+Note: This parameter is valid only when the custom dialog box is in the default style.
+
+**Reference**
+
+[Custom Dialog Box](../reference/arkui-ts/ts-methods-custom-dialog-box.md)
+
+## How do I remove the white background of a custom dialog box?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+When in the default style a custom dialog box comes with a white background.
+
+**Solution**
+
+To remove the white background, set the custom dialog box to a custom style.
+
+1.  During initialization of the custom dialog box, set **customStyle** to **true**.
+2.  During initialization of the custom dialog box, set **backgroundColor** to the color you prefer.

+
+## How do I customize the eye icon for the password input mode of the \<TextInput> component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+The eye icon for the password input mode (with the **type** attribute of the **\<TextInput>** component set to **InputType.Password**) cannot be customized.
+
+**Solution**
+
+The eye icon itself cannot be customized. You can use set the **showPasswordIcon** attribute of the **\<TextInput>** component to **false** to hide the icon, and use the **\<Image>** component to control the type of the **\<TextInput>** component.
+
+**Reference**
+
+[TextInput](../reference/arkui-ts/ts-basic-components-textinput.md)
+
+## How do I use the onSubmit event of the \<TextInput> component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Solution**
+
+The **onSubmit** event is triggered when a user presses **Enter** on the (physical or soft) keyboard. The callback parameter in the event is the current Enter key type. The Enter key type can be set through the **enterKeyType** attribute of the **\<TextInput>** component. Setting the key style of the soft keyboard requires support by the input method.
+
+**Reference**
+
+[TextInput](../reference/arkui-ts/ts-basic-components-textinput.md)
+
+## How do I set the caret position to the start point for when the \<TextInput> component obtains focus?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+When the **\<TextInput>** component obtains focus, the caret automatically moves to the position of the touch point, instead of the start position.
+
+**Solution**
+
+1.  Bind the **\<TextInput>** component to the **onEditChange** event, which is triggered when the component enters the input state.
+2.  Call the **setTimeout** API for asynchronous processing. Then call the **TextInputController.caretPosition** API in the event callback to set the caret position.
+
+**Example**
+
+```
+@Entry
+@Component
+struct TextInputDemo {
+  controller: TextInputController = new TextInputController()
+
+  build() {
+    Column() {
+      TextInput({ controller: this.controller })
+        .onEditChange((isEditing: boolean) => {
+          if (isEditing) {
+            setTimeout(() => {
+              this.controller.caretPosition(0)
+            }, 100)

+## How do I obtain the current scrolling offset of a scrollable component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Solution**
+
+1.  During initialization of the scrollable component, such as **\<List>**, **\<Grid>**, and **\<Scroll>**, set the **scroller** parameter to bind the component to a scroll controller.
+2.  Call the **currentOffset** API of the controller to obtain the horizontal and vertical scrolling offsets.

+[Scroll](../reference/arkui-ts/ts-container-scroll.md#currentoffset)
+
+## How do I align text vertically?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+Text cannot be aligned vertically in the **\<Text>** component.
+
+**Solution**
+
+Text is aligned horizontally in the **\<Text>** component. To enable text to align vertically, you can split the file, use the **\<Flex>** container component, and set its main axis direction to vertical.
+
+**Example**
+
+```
+@Entry
+@Component
+struct Index15 {
+  private message: string = 'This document is intended for novices in developing applications. It introduces you to the application development process and main files in the project director, by walking you through the building of a simple application with the page redirection/return feature.';

+
+Set the background color of the top container component to transparent, and then set the **opacity** attribute of the XComponent to **0.01**.
+
+Example:
+
+```
+build() {
+  Stack() {
+    XComponent({
+    id: 'componentId',
+    type: 'surface',
+    })
+    .width('100%')
+    .height('100%')
+    .opacity(0.01)
+    // Page content
+  }
+  .width('100%')
+  .height('100%')
+  .backgroundColor('rgba(255,255,255, 0)')
+}
+```
+
+## Why do the constraintSize settings fail to take effect?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+If **constraintSize** is set for a component and the width of its child component is set to a percentage, for example, **width\('100%'\)**, **constraintSize** takes effect by multiplying the maximum width by the percentage. As a result, the child component may overflow, in which case it looks like the **constraintSize** settings fail to take effect.
+
+**Solution**
+
+You can use the **\<Scroll>** component at the outer layer. In this way, when **constraintSize** is set and the space occupied by a child component exceeds the specified constraint value, a scrollbar will be displayed.
+
+## How do I set the background color to transparent?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Set **backgroundColor** to **'\#00000000'**.
+
+## What should I do if the \<Scroll> component cannot scroll to the bottom?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+Unless otherwise specified, the height of the **\<Scroll>** component is equal to the window height. In this case, the component's bottom area will be blocked by components (if any) outside of it.
+
+**Solution**
+
+Set the height of the **\<Scroll>** component or use the flex layout to limit this height.
+
+## What is the counterpart of CenterCrop in OpenHarmony for backgroundImage?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Solution**
+
+To achieve the equivalent effect CenterCrop – place the image in the center of the window and scale the image while maintaining its aspect ratio, you can use the universal attributes **backgroundImageSize**\(**ImageSize.cover**\) and **backgroundImagePosition** \(**Alignment.Center**\).
+
+## How do I customize the control bar style of the \<Video> component?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Solution**
+
+1. Set **controls** to **false** to disable the default control bar.
+
+2. Sets **controller** for the **\<Video>** component.
+
+3. Implement a custom control bar in ArkTS and use **VideoController** to control video playback.
+
+**Example**
+
+```
+// xxx.ets
+@Entry@Componentstruct VideoCreateComponent {
+  @State videoSrc: Resource = $rawfile('video1.mp4')
+  @State previewUri: Resource = $r('app.media.poster1')

+## How do I set state-specific styles for a component?
+
+**Solution**
+
+You can use the **stateStyles** attribute to set styles of a component for different states (stateless, pressed, disabled, focused, or clicked).
+
+**Example**
+
+```
+//xxx.ts
+@Entry
+@Component
+struct StyleExample {
+  @State isEnable: boolean = true;
+
+  @Styles pressedStyles() {
+    .backgroundColor("#ED6F21")

+## What should I do if the flex width and height in the \<Scroll> component conflicts with the scrolling?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9, stage model)
+
+**Symptom**
+
+When a container component with a fixed size is added to the **\<Scroll>** component, a scrolling error occurs.
+
+**Solution**
+
+Do not set a size for any container component in the **\<Scroll>** component. In this way, the **\<Scroll>** component can adapt its size to the content.
+
+## What should I do if the height settings in position do not take effect?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+After **position** is set for a container component, the **height** settings do not work.
+
+**Solution**
+
+When **position** is set for a container component, it is taken out of normal flow and works independently from the outer container. In this case, the height does not take effect. You can replace the outer container with a stack to solve this issue.
+
+## Why can't the onBlur or onFocus callback be triggered?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+By default, only the Tab button and arrow buttons on the connected keyboard can be used to trigger the focus event. To trigger a focus event by a touch, add the **focusOnTouch** attribute for the target component.
+
+**Reference**
+
+[Focus Control](../reference/arkui-ts/ts-universal-attributes-focus.md)
+
+## How do I disable the scroll event of a \<Grid> nested in the \<Scroll>?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+You can use the **onScrollFrameBegin** event and **scrollBy** API to implement nested scrolling of the containers.
+
+For details, see [Nested Scrolling Example](../reference/arkui-ts/ts-container-scroll.md#example-2).
+
+## How do I enable a component to rotate continuously?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+You can use [attribute animation](../reference/arkui-ts/ts-animatorproperty.md) to that effect.
+
+## How do I scroll a list with the keyboard?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+- Add **focusable\(true\)** to the list item to enable it to obtain focus.
+- Nest a focusable component, for example, **\<Button>**, at the outer layer of each item.
+
+## Why is the click event not triggered for the focused component upon the press of the Enter key after keyboard navigation?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+By default, the built-in click event of the component and the custom **onClick** click event are bound to the space bar instead of the Enter key.
+
+## How do I block event bubbling when a button is nested in multi-layer components?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+You can bind the button to the **stopPropagation** parameter.
+
+## How do I dynamically create components using code in ArkUI?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+ArkUI uses the ArkTS declarative development paradigm. Developers cannot hold component instances. During declaration, you can control component creation by rendering control syntax and dynamically building UI elements.
+
+**Example**
+
+```
+// Create a component using the if statement.
+if(this.isTrue) {
+  Text ("Create Text Component").fontSize (30)
+}
+// Create a component using the ForEach statement.
+ForEach(this.nums,(item) => {
+  Text(item + '').fontSize(30)
+},item => JSON.stringify(item))

+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+The @Builder decorated method allows for use of a custom component, while regular methods do not. If a custom component is used in an @Builder decorated method, it is re-created each time the method is called.

+
+**Solution**
+
+-   Without parameters
+
+    If no parameter is passed when assigning a value to the **@BuilderParam** decorated attribute (for example, **content: this.specificParam**), define the type of the attribute as a function without a return value (for example, **@BuilderParam content: \(\) =\> void**).
+
+-   With parameters
+
+    If any parameter is passed when assigning a value to the **@BuilderParam** decorated attribute (for example, **callContent: this.specificParam1\("111"\)**), define the type of the attribute as **any** (for example, **@BuilderParam callContent: any**).

+## How do I listen for object changes in an array?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+To listen for object changes in an array, use the @Observed and @ObjectLink decorators. **@Observed** applies to classes, and **@ObjectLink** applies to variables.
+
+**Example**
+
+1.  Use @Observed on a class.
+
+    ```
+    @Observed
+    class ClassA {
+      public name: string
+      public c: number
+      public id: number
+    
+      constructor(c: number, name: string = 'OK') {
+        this.name = name
+        this.c = c
+      }
+    }
+    ```
+
+2.  Use @ObjectLink on a component variable.
+
+    ```
+    @Component
+    struct ViewA {
+      label: string = 'ViewA1'
+      @ObjectLink a: ClassA
+    
+      build() {
+        Row() {
+          Button(`ViewA [${this.label}] this.a.c= ${this.a.c} +1`)
+            .onClick(() => {
+              this.a.c += 1

+## How do I transfer values through the parent component to @Link decorated varaibles in a child component?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+To enable a child component to receive the value from the parent component through @Link, '**\$**' must be used to first establish a reference relationship between variables in the child and parent components.  
+
+**Example**
+
+The **@Link** semantics are derived from the '**$**' operator. In other words, **$isPlaying** is the two-way binding of the internal state **this.isPlaying**. When the button in the **PlayButton** child component is touched, the value of the @Link decorated variable is changed, and **PlayButton** together with the **\<Image>** and **\<Text>** components of the parent component is refreshed. Similarly, when the button in the parent component is touched, the value of **this.isPlaying** is changed, and **PlayButton** together with the **\<Text>** and **\<Button>** components of the parent component is refreshed.
+
+1.  Use the @State decorator in the parent component and use the '**\$**' operator to create a reference for transferring data.
+
+    ```
+    @Entry
+    @Component
+    struct Player {
+      @State isPlaying: boolean = false
+      build() {
+        Column() {
+          PlayButton({ buttonPlaying: $isPlaying })
+          Text(`Player is ${this.isPlaying ? '' : 'not'} playing`).fontSize(18)
+          Button('Parent:' + this.isPlaying)
+            .margin(15)
+            .onClick(() => {
+              this.isPlaying = !this.isPlaying
+            })
+        }
+      }
+    }
+    
+    
+    ```
+
+2.  Use @Link in the child component to receive data.
+
+    ```
+    @Component
+    struct PlayButton {
+      @Link buttonPlaying: boolean
+    
+      build() {
+        Column() {
+          Button(this.buttonPlaying ? 'pause' : 'play')
+            .margin(20)
+            .onClick(() => {
+              this.buttonPlaying = !this.buttonPlaying
+            })

+## How does a component synchronize state with its grandchild components?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+-   Method 1 (recommended): Use the @Provide and @Consume decorators. Specifically, use @Provide in the component and @Consume in the grandchild component to implement two-way data binding between the components.
+
+-   Method 2: Use the @State and @Link decorators. Specifically, use @State in the parent component and @Link in each layer of child components (child and grandchild components).
+
+**Example 1**
+
+1.  Include a child component in the component. Employ @Provide in the component to provide the **reviewVote** parameter to its grandchild component.
+
+    ```
+    @Entry
+    @Component
+    struct Father{
+      @Provide("reviewVote") reviewVotes: number = 0;
+    
+      build() {
+        Column() {
+          Son()
+          Button(`Father: ${this.reviewVotes}`)
+            ...
+        }
+      }
+    }
+    ```
+
+2.  Include the grandchild component in the child component.
+
+    ```
+    @Component
+    struct Son{
+      build() {
+        Column() {
+          GrandSon()
+        }
+      }
+    }
+    ```
+
+3.  Employ @Consume in the grandchild component to receive the **reviewVote** parameter.
+
+    ```
+    @Component
+    struct GrandSon{
+      @Consume("reviewVote") reviewVotes: number
+    
+      build() {
+        Column() {
+          Button(`GrandSon: ${this.reviewVotes}`)
+            ...
+        }.width('100%')
+      }
+    }
+    ```
+
+
+**Example 2**
+
+1.  Employ @State in the component **Father** to decorate **reviewVote**.
+
+    ```
+    @Entry
+    @Component
+    struct Father {
+      @State reviewVotes: number = 0;
+    
+      build() {
+        Column() {
+          Son({reviewVotes:$reviewVotes})
+          Button(`Father: ${this.reviewVotes}`)
+            ...
+        }
+      }
+    }
+    ```
+
+2.  Employ @Link in the child component **Son** to receive the **reviewVote** parameter passed from **Father**.
+
+    ```
+    @Component
+    struct Son{
+      @Link reviewVotes: number;
+      build() {
+        Column() {
+          Grandson({reviewVotes:$reviewVotes})
+        }
+      }
+    }
+    
+    
+    ```
+
+3.  Employ @Link in the grandchild component **GrandSon** to receive the **reviewVote** parameter passed from **Son**.
+
+    ```
+    @Component
+    struct Grandson{
+      @Link reviewVotes: number;
+    
+      build() {
+        Column() {
+          Button(`Grandson: ${this.reviewVotes}`)

+## How is a callback function defined in JS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+The following is an example to illustrate how to define a callback function:
+
+1.  Define the callback function.
+
+    ```
+    // Define a callback function that contains two parameters and returns void.
+    myCallback: (a:number,b:string) => void
+    ```
+
+2.  Initialize the callback function by assigning values.
+
+    ```
+    aboutToAppear() {
+      // Initialize the callback function.
+      this.myCallback= (a,b)=>{
+        console.info(`handle myCallback a=${a},b=${b}`)
+      }}
+    ```
+
+
+## How do I maximize performance in cases when a component needs to be updated for multiple times?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Use the state management module for the purpose. Currently, the minimum update is supported. When the data dependency changes, instead of updating the entire custom component, only the view content that depends on the data is updated.
+
+## How does this of a function in an object point to the outer layer?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+You can use the arrow function for this purpose.
+
+**Example**
+
+```
+const obj = {
+  start:() => {
+    return this.num
+  }
+}
+```
+
+## How do I obtain data through an API before page loading?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+Data needs to be obtained before page rendering so as to be rendered when needed.
+
+**Solution**
+
+In the **aboutToAppear** function, use an asynchronous API to obtain page data and @State to decorate related variables. After the data is obtained, the page is automatically refreshed based on the variables.
+
+**Example**
+
+```
+@Entry
+@Component
+struct Test6Page {
+  // After the data is obtained, the page is automatically refreshed.
+  @State message: string = 'loading.....'
+  aboutToAppear(){
+    // Simulate an asynchronous API to obtain data.
+    setTimeout(()=>{
+      this.message = 'new msg'
+    },3000)
+  }
+  build() {
+    Row() {
+      Column() {
+        Text(this.message)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+
+## Can placeholders be configured in the string.json file in the stage model?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)

+
+ArkTS is a superset of TypeScript. In addition to all TS features, ArkTS offers added declarative UI features, allowing you to develop high-performance applications in a more natural and intuitive manner. It is recommended that you use ArtTS for UI development and TS for service logic development.

+
+## How do I send a verification code through email in ArkTS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+To send a verification code, you need to request the server, which in turn calls the SMS verification code API. The SMS service can be used to implement related functions.
+
+## How do I display sensor data in the \<Text> component on the UI in real time?
+
+Applicable to: OpenHarmony 3.2 Beta5 (API version 9)
+
+**Solution**
+
+The type of data returned by the sensor is double. To display it in the \<Text> component, first convert the data from double to string.
+
+## How do I listen for screen rotation events?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+To listen for screen rotation events, use the **mediaquery** API.
+
+```
+import mediaquery from '@ohos.mediaquery'
+let listener = mediaquery.matchMediaSync('(orientation: landscape)'); // Listen for landscape events.
+function onPortrait(mediaQueryResult) {
+  if (mediaQueryResult.matches) {
+   // do something here
+  } else {
+   // do something here
+  }
+}
+listener.on('change', onPortrait) // Register a callback.
+listener.off('change', onPortrait) // Deregister a callback.
+```
+
+**Reference**
+
+[@ohos.mediaquery (Media Query)](../reference/apis/js-apis-mediaquery.md)
+
+## What should I do if ForEach does not traverse all data after DevEco Studio is updated to the latest version?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+In the **forEach\(\)** statement, if the third parameter **keyGenerator** has a value passed in, ensure that the key generated by each element in the data source array is unique. Otherwise, the traversal cannot be performed. If the generated keys are the same, only one key can be generated.
+
+The traversal can also be performed if **keyGenerator** is not specified, in which case the system uses the default generation mode.
+
+## What should I do if a singleton does not take effect after the page is changed?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+A singleton works only in the same page. It becomes **undefined** when the page changes.
+
+**Solution**
+
+A JS file is generated for each page, and a defined singleton is generated in each JS file. Therefore, the singleton in applicable only to the owning page.
+
+To share an instance across pages, it must be created at the UIAbility or application level.
+
+## How do I convert a string in time format to a date object?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+If the string is in the yyyy-MM-dd format, you can convert it to a date object by calling **new Date\("yyyy-MM-dd"\)**.
+
+```
+new Date("2021-05-23");
+new Date("2020/2/29");
+new Date("2020-14-03");
+new Date("14-02-2021");
+```
+
+If the string is in other formats, you can convert it to a date object by calling **new Date\(year:number,month:number,day?:number,hour?:number,minute?:number,second?:number,ms?:number\)**.
+
+```
+Syntax for creating a date based on parameters:
+new Date(yearValue, IndexOfMonth, dayValue, hours, minutes, seconds)
+```
+
+Pass the date parameters as arguments.
+
+-   **yearValue**: the year in the ISO 8061 YYYY format, for example, **2021**. If we specify a value in YY format, it will be incorrectly accepted. For example, the value **21** would be considered the year 1921 rather than 2021.
+-   **IndexOfMonth**: index of the month, which starts from 0. It is obtained by subtracting 1 from the month value. For example, for March, the month value is 3, but the value of **IndexOfMonth** will be 2 (that is, 3 – 1 = 2). The value should typically be within the 0–11 range.
+-   **dayValue**: day of the month. It should range from 1 to 31 depending on the number of days in the month. For example, for 21-05-2021, the day value is **21**.
+-   **hours**: hour of the day. For example, **10** for 10 o'clock.
+-   **minutes**: number of minutes that have elapsed in the hour.
+-   **seconds**: number of seconds past a minute.
+
+## How do I convert a string to a byte array in ArkTS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Refer to the following code:
+
+```
+stringToArray(str:string) {
+  var arr = [];
+  for(var i = 0,j = str.length;i<j;++i) {
+ arr.push(str.charCodeAt(i))
+  }
+  return arr;
+}
+```
+
+## How do I implement string encoding and decoding in ArkTS?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+You can use **TextEncoder** and **TextDecoder** provided by the **util** module.
+
+**Reference**
+
+[TextEncoder](../reference/apis/js-apis-util.md#textencoder), [TextDecoder](../reference/apis/js-apis-util.md#textdecoder)
+
+## How do I import and export namespaces?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+Use **import** and **export** statements.
+
+-   Exporting namespaces from the database:
+
+    ```
+    namespace Util{
+        export function getTime(){
+            return Date.now()
+        }
+    }
+    export default Util
+    ```
+
+-   Importing namespaces
+
+    ```
+    import Util from './util'
+    Util.getTime()
+    ```
+
+
+## Can relational database operations be performed in the Worker thread?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+Currently, the relational database (RDB) object in the UI main thread cannot be sent to the Worker thread for operations. To use the RDB in the Worker thread, you must obtain a new RDB object.
+
+## How do I obtain files in the resource directory of an application?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Solution**
+
+-   Method 1: Use **\$r** or **\$rawfile**. This method applies to static access, during which the **resource** directory remains unchanged when the application is running.
+-   Method 2: Use **ResourceManager**. This method applies to dynamic access, during which the **resource** directory dynamically changes when the application is running.
+
+**Reference**
+
+[Resource Categories and Access](../quick-start/resource-categories-and-access.md) and [@ohos.resourceManager (Resource Manager)](../reference/apis/js-apis-resource-manager.md)
+
+
+## How do I convert the XML format to the JSON format?
+
+Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)
+
+**Symptom**
+
+The data returned by the server is encoded using Base64 in XML format and needs to be converted to the JSON format for subsequent processing.
+
+**Solution**
+
+Use the Base64-related APIs in the **util** module to decode data, and then use the **convertxml** module to parse data in XML format.
+
+**Example**
+
+```
+import convertxml from '@ohos.convertxml';
+import util from '@ohos.util';
+
+@Entry
+@Component
+struct Faq_4_31 {
+  @State message: string = 'base64 to JSON'

+    Row() {
+      Column() {
+        Text(this.message)

+**Problem**
+
+After a notification is published, no error log is displayed, and no notification is displayed in the notification panel.
+
+**Solution**
+
+Before publishing a notification, you must enable the notification feature for your application in the system settings of the real device so that the notification can be viewed in the notification panel.
+
+To manually enable the notification feature, choose **Settings** > **Notification & status bar** > *Application name* > **Allow notifications**.
+
+You can also call the **notificationManager.requestEnableNotification\(\)** API to display a dialog box (only once) to prompt the user to enable the feature.

+
+The macro for accessing the directory is **\$\{CMAKE\_CURRENT\_SOURCE\_DIR\}/../../../libs/$\{OHOS\_ARCH\}/xxxx.so**.
+
+**CMAKE\_CURRENT\_SOURCE\_DIR**: directory where the **CMakeList.txt** file is stored.
+
+**OHOS\_ARCH**: type of the application binary interface (ABI). The value can be **armeabi-v7a** or **arm64-v8a**. The default value is **arm64-v8a**.
+
+**Example**
+
+Add the link library to **CMakeLists.txt**.
+
+```
+target_link_libraries(entry PUBLIC
+    libace_napi.z.so
+    libhilog_ndk.z.so
+    ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libMyDemo.so
+)
+```
+
+## What should I do if an error is reported when OH\_LOG\_Print in the native code is used to print logs?
+
+Applicable to: OpenHarmony 3.1 Beta 5 (API version 9)
+
+**Problem**
+
+When **OH\_LOG\_Print** is used in the native code to print logs, the following error is reported: **undefined symbol: OH\_LOG\_Print**.
+
+**Cause**
+
+The link library file is missing.
+
+**Solution**
+
+Open the **CMakeLists.txt** file and append **libhilog\_ndk.z.so** to **target\_link\_libraries**.
+
+```
+set(NATIVERENDER_ROOT_PATH ${CMAKE_CURRENT_SOURCE_DIR})
+target_link_libraries(entry PUBLIC
+    libace_napi.z.so
+    libhilog_ndk.z.so
+)
+```
+
+## How do I traverse files in rawfile?
+
+Applicable to: OpenHarmony 3.1 Beta 5 (API version 9)
+
+**Solution**
+
+Use the **OH\_ResourceManager\_OpenRawDir\(\)** native API to obtain the root directory of **rawfile** and traverse the root directory.
+
+**Reference**
+
+[Rawfile](../reference/native-apis/rawfile.md)
