## Before You Start<a name="section965173113911"></a>
1. Install DevEco Studio and configure the development environment. For details, see [Configuring the OpenHarmony SDK](configuring-openharmony-sdk.md).
2. Create a project as instructed in [Creating an OpenHarmony Project](create-openharmony-project.md).
- If you are using the JavaScript language, select **Empty Ability** for **Template** and **JS** for **Language**.
3. Use the [previewer](https://developer.harmonyos.com/en/docs/documentation/doc-guides/previewer-0000001054328973#EN-US_TOPIC_0000001056725592__section16523172216252) or [emulator](https://developer.harmonyos.com/en/docs/documentation/doc-guides/run_simulator-0000001053303709) to run the project.
Now you have created your first OpenHarmony project. You can continue the development by following instructions in [Getting Started with JavaScript](start-with-js.md).

# Getting Started with JavaScript<a name="EN-US_TOPIC_0000001168007068"></a>
For best results, use the [latest version of DevEco Studio](https://developer.harmonyos.com/en/develop/deveco-studio#download) for your development.
## Building the First Page<a name="section1754373063820"></a>
1. Add a **Text** and a **Button** component to the first page.
In the **Project** window, choose **entry** \> **src** \> **main** \> **js** \> **default** \> **pages** \> **index**, open the **index.hml** file, and add the components.
```
<!-- index.hml -->
<div class="container">
<!-- Add text. -->
<text class="text">
Hello World
</text>
<!-- Add a button, set its type to capsule, set button text to Next, and bind it to the launch event. -->
<button class="button" type="capsule" value="Next" onclick="launch"></button>
</div>
```
2. Open the **index.css** file and set text and button styles.
```
/* index.css */
.container {
flex-direction: column; /* Arrange container items vertically. */
justify-content: center; /* Center the items along the main axis of the container. */
align-items: center; /* Center the items along the cross axis of the container. */
width:100%;
height:100%;
}
/* Set the style for the component of the text class. */
.text{
font-size: 42px;
}
/* Set the style for the component of the button class. */
.button {
width: 240px;
height: 60px;
background-color: #007dff;
font-size: 30px;
text-color: white;
margin-top: 20px;
}
```

1. In the **Project** window, choose **entry** \> **src** \> **main** \> **js** \> **default**, right-click the **pages** folder, and then choose **New** \> **JS Page**. Name the new page **details** and press **Enter**.
Below is the structure of the **pages** folder:
![](figures/en-us_image_0000001167850660.png)
2. Open the **details.hml** file, add the **<text\>** component, and set its layout.
```
<!-- details.hml -->
<div class="container">
<text class="text">
Hi there
</text>
</div>
```
3. Open the **details.css** file and set the text style.
```
/* details.css */
.container {
flex-direction: column;
justify-content: center;
align-items: center;
width:100%;
height:100%;
}
.text {
font-size: 42px;
text-align: center;
}
```
## Implementing Page Redirection<a name="section55441830123814"></a>
1. Open the **index.js** file and import the router module. The page router finds the target page based on its URI for the redirection. The sample code is as follows:
```
// index.js
import router from '@system.router';
export default {
launch() {
router.push ({
uri:'pages/details/details', // Specify the page to be redirected to.
})
}
}
```

## Modules to Import
```
import webgl from 'ohos.webglnapi'
import webgl from '@ohos.webglnapi';
```
## System Capabilities
## Invoking Method
SystemCapability.Graphic.Graphic2D.WebGL2
Create a **&lt;canvas&gt;** component in the HML file. The following is an example:
```
<div class="container">
<canvas ref="canvas1" style="width : 400px; height : 200px; background-color : lightyellow;"></canvas>
<button class="btn-button" onclick="BtnDraw2D">BtnDraw2D</button>
</div>
```
## Invoking Method
Obtain the **&lt;canvas&gt;** component instance in the JS file. The following is an example:
```
// Obtain the <canvas\> component instance.
const el = this.$refs.canvas
// Obtain the WebGL context from the <canvas\> component instance.
// Obtain the <canvas> component instance.
const el = this.$refs.canvas1;
// Obtain the WebGL context from the <canvas> component instance.
const gl = el.getContext('webgl');
const gl2 = el.getContext('webgl2');
// Call the WebGL API.
gl2.readBuffer(gl.COLOR_ATTACHMENT0)
gl.clearColor(0.0, 0.0, 0.0, 1.0);

# 开发准备
## 任务说明
本文档适用于应用开发的初学者。通过构建一个简单的具有页面跳转功能的应用（如下图[预览器](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/previewer-0000001054328973#ZH-CN_TOPIC_0000001056725592__section16523172216252)运行效果所示），熟悉应用开发流程。
为确保运行效果，本文以使用**DevEco Studio 3.0 Beta2**版本为例，点击[此处](https://developer.harmonyos.com/cn/develop/deveco-studio#download_beta)获取下载链接。
![zh-cn_image_0000001089359413](figures/zh-cn_image_0000001089359413.png)
**表1** 方舟开发框架的对比
| 比较项 | 基于JS扩展的类Web开发范式 | 基于TS扩展的声明式开发范式 |
| -------- | -------- | -------- |
| 语言生态 | JS | eTS |
| 接口方式 | 类Web范式 | 声明式 |

| 相对优势 | 轻量化，开发更简便 | 极简开发，内存占用更少、运行性能更高 |
接下来，分别使用JS语言、eTS语言实现上述两个页面跳转的功能。
## 开发准备
1. 开始前请参考[配置OpenHarmony SDK](../quick-start/configuring-openharmony-sdk.md)，完成**DevEco Studio**的安装和开发环境配置。
2. 开发环境配置完成后，请参考[创建OpenHarmony工程](../quick-start/use-wizard-to-create-project.md)创建工程。
- 使用JS语言开发，模板选择Empty Ability，Language选择JS。
- 使用eTS语言开发，模板选择Empty Ability，Language选择eTS。
3. 工程创建完成后，使用[预览器](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/previewer-0000001054328973#ZH-CN_TOPIC_0000001056725592__section16523172216252)运行该工程。
完成上述操作后，请参考[使用JS语言开发](../quick-start/start-with-js.md)、[使用eTS语言开发](../quick-start/start-with-ets.md)继续下一步的学习。

# 使用eTS语言开发
> ![icon-note.gif](public_sys-resources/icon-note.gif) **说明：**
> 请使用DevEco Studio V3.0.0.601 Beta1及更高版本。本文以使用**DevEco Studio 3.0 Beta2**版本为例，点击[此处](https://developer.harmonyos.com/cn/develop/deveco-studio#download_beta)获取下载链接。
## 创建eTS工程
1. 打开DevEco Studio，创建一个新工程，选择模板，如Empty Ability：
![zh-cn_image_0000001238733799](figures/zh-cn_image_0000001238733799.png)
2. 进入配置工程界面，Project Type选择Application，Language选择eTS，其他参数根据实际需要设置即可。
![zh-cn_image_0000001238853759](figures/zh-cn_image_0000001238853759.png)
## 编写第一个页面
1. 工程创建完成后，在"Project"窗口，点击entry &gt; src &gt; main &gt; ets &gt; default &gt; pages，打开index.ets文件。
![zh-cn_image_0000001213883165](figures/zh-cn_image_0000001213883165.png)
2. 第一个页面由Flex容器组件、Text组件和Button组件构成。在index.ets中编写并设置页面组件的属性和样式，示例代码如下所示：
```
@Entry
@Component
struct Index {
build() {
//Flex容器组件
Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
//Text组件
Text('Hello World')
.fontSize(60)
.fontWeight(500)
//Button组件
Button('Next')
.fontSize(40)
.fontWeight(500)
.width(280)
.height(60)
}
//容器整体宽高
.width('100%')
.height('100%')
}
}
```
3. 使用[预览器](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/previewer-0000001054328973#ZH-CN_TOPIC_0000001056725592__section16523172216252)运行项目，效果如下图所示：
![zh-cn_image_0000001168898456](figures/zh-cn_image_0000001168898456.png)
## 创建第二个页面
1. 在"Project"窗口，打开entry &gt; src &gt; main &gt; ets &gt; default，右键点击pages文件夹，选择NeweTS Page，命名为details，单击回车键。创建完成后，可以看到pages文件夹下的文件目录结构如下：
![zh-cn_image_0000001214043107](figures/zh-cn_image_0000001214043107.png)
2. 第二个页面由Flex容器组件、Text组件构成。在details.ets中编写并设置页面组件的属性和样式，示例代码如下所示：
```
@Entry
@Component
struct Details {
build() {
//Flex容器组件
Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
//Text组件
Text('Hi there')
.fontSize(60)
.fontWeight(500)
}
//容器整体宽高
.width('100%')
.height('100%')
}
}
```
## 实现页面跳转
1. 打开第一个页面的index.ets文件，导入router模块，页面路由router根据页面的uri来找到目标页面，从而实现跳转。示例代码如下：
```
//导入router模块
import router from '@system.router';
@Entry
@Component
struct Index {
build() {
//Flex容器组件
Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
//Text组件
Text('Hello World')
.fontSize(60)
.fontWeight(500)
//Button组件
Button('Next')
.fontSize(40)
.fontWeight(500)
.width(280)
.height(60)
//点击Button实现页面跳转
.onClick(() => { router.push({ uri: 'pages/details' }) })
}
//容器整体宽高
.width('100%')
.height('100%')
}
}
```
2. 再次使用[预览器](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/previewer-0000001054328973#ZH-CN_TOPIC_0000001056725592__section16523172216252)运行项目，效果如下图所示：
![zh-cn_image_0000001169221404](figures/zh-cn_image_0000001169221404.png)

<button class="button" type="capsule" value="Next" onclick="launch"></button>
</div>
```
2. 打开index.css文件，设置文本和按钮的样式，示例代码如下：
```
/* index.css */
.container {
flex-direction: column; /* 设置容器内的项目纵向排列 */
justify-content: center; /* 设置项目位于容器主轴的中心 */
align-items: center; /* 项目在交叉轴居中 */
width:100%;
height:100%;
}
/* 对class="text"的组件设置样式 */
.text{
font-size: 42px;
}
/* 对class="button"的组件设置样式 */
.button {
width: 240px;
