 基于OpenHarmony的应用模型，可以通过以下几种方式来实现UIAbility组件与UI之间的数据同步。
 
 - [使用EventHub进行数据通信](#使用eventhub进行数据通信)：在基类Context中提供了EventHub对象，可以通过发布订阅方式来实现事件的传递。在事件传递前，订阅者需要先进行订阅，当发布者发布事件时，订阅者将接收到事件并进行相应处理。
-- [使用globalThis进行数据同步](#使用globalthis进行数据同步)：在ArkTS引擎实例内部，globalThis是一个全局对象，可以被ArkTS引擎实例内的UIAbility组件、ExtensionAbility组件和ArkUI页面（Page）访问。

-## 使用globalThis进行数据同步
-
-globalThis是[ArkTS引擎实例](thread-model-stage.md)内部的一个全局对象，引擎内部的UIAbility/ExtensionAbility/Page都可以使用，因此可以使用globalThis对象进行数据同步。
-
-**图1** 使用globalThis进行数据同步
-![globalThis1](figures/globalThis1.png)
-
-
-如上图所示，下面从如下三个场景和一个注意点来介绍globalThis的使用：
-
-- [UIAbility和Page之间使用globalThis](#uiability和page之间使用globalthis)
-- [UIAbility和UIAbility之间使用globalThis](#uiability和uiability之间使用globalthis)
-- [UIAbility和ExtensionAbility之间使用globalThis](#uiability和extensionability之间使用globalthis)
-- [globalThis使用的注意事项](#globalthis使用的注意事项)
-
-### UIAbility和Page之间使用globalThis
-
-通过在globalThis对象上绑定属性/方法，可以实现UIAbility组件与UI之间的数据同步。例如在UIAbility组件中绑定want参数，即可在UIAbility对应的UI上使用want参数信息。
-
-1. 调用[`startAbility()`](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextstartability)方法启动一个UIAbility实例时，被启动的UIAbility创建完成后会进入[`onCreate()`](../reference/apis/js-apis-app-ability-uiAbility.md#uiabilityoncreate)生命周期回调，且在[`onCreate()`](../reference/apis/js-apis-app-ability-uiAbility.md#uiabilityoncreate)生命周期回调中能够接受到传递过来的want参数，可以将want参数绑定到globalThis上。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility';
-
-   export default class EntryAbility extends UIAbility {
-     onCreate(want, launch) {
-       globalThis.entryAbilityWant = want;
-       ...
-     }
-
-     ...
-   }
-   ```
-
-2. 在UI中即可通过globalThis获取到want参数信息。
-
-   ```ts
-   let entryAbilityWant;
-
-   @Entry
-   @Component
-   struct Index {
-     aboutToAppear() {
-       entryAbilityWant = globalThis.entryAbilityWant;
-     }
-
-     // 页面展示
-     build() {
-       ...
-     }
-   }
-   ```
-
-
-### UIAbility和UIAbility之间使用globalThis
-
-在同一个应用中，UIAbility与UIAbility之间的数据传递可以通过将数据绑定到全局变量globalThis上进行同步。例如，在UIAbilityA中将数据保存在globalThis对象中，然后跳转到UIAbilityB中就可以获取该数据。
-
-1. UIAbilityA中保存数据一个字符串数据并挂载到globalThis上。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
-
-   export default class UIAbilityA extends UIAbility {
-     onCreate(want, launch) {
-       globalThis.entryAbilityStr = 'UIAbilityA'; // UIAbilityA存放字符串“UIAbilityA”到globalThis
-       ...
-     }
-   }
-   ```
-
-2. UIAbilityB中获取对应的数据。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
-
-   export default class UIAbilityB extends UIAbility {
-     onCreate(want, launch) {
-       // UIAbilityB从globalThis读取name并输出
-       console.info('name from entryAbilityStr: ' + globalThis.entryAbilityStr);
-       ...
-     }
-   }
-   ```
-
-
-### UIAbility和ExtensionAbility之间使用globalThis
-
-在同一个应用中，UIAbility和ExtensionAbility之间的数据传递也可以通过将数据绑定到全局变量globalThis上进行同步。例如，在UIAbilityA中保存数据，在ServiceExtensionAbility中就可以获取该数据。
-
-1. UIAbilityA中保存数据一个字符串数据并挂载到globalThis上。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
-
-   export default class UIAbilityA extends UIAbility {
-     onCreate(want, launch) {
-       // UIAbilityA存放字符串“UIAbilityA”到globalThis
-       globalThis.entryAbilityStr = 'UIAbilityA';
-       ...
-     }
-   }
-   ```
-
-2. ExtensionAbility中获取数据。
-
-   ```ts
-   import Extension from '@ohos.app.ability.ServiceExtensionAbility'
-
-   export default class ServiceExtAbility extends Extension {
-     onCreate(want) {
-       // ServiceExtAbility从globalThis读取name并输出
-       console.info('name from entryAbilityStr: ' + globalThis.entryAbilityStr);
-       ...
-     }
-   }
-   ```
-
-
-### globalThis使用的注意事项
-
-**图2** globalThis注意事项
-![globalThis2](figures/globalThis2.png)
-
-- Stage模型下进程内的UIAbility组件共享ArkTS引擎实例，使用globalThis时需要避免存放相同名称的对象。例如UIAbilityA和UIAbilityB可以使用globalThis共享数据，在存放相同名称的对象时，先存放的对象会被后存放的对象覆盖。
-
-- globalThis不支持跨进程使用，不同进程的UIAbility组件和ExtensionAbility组件无法使用globalThis共享数据，进程模型及进程间通信机制见[进程模型概述](./process-model-stage.md#进程模型概述)。
-
-- FA模型因为每个UIAbility组件之间引擎隔离，不会存在该问题。
-
-- 对于绑定在globalThis上的对象，其生命周期与ArkTS虚拟机实例相同，建议在使用完成之后将其赋值为null，以减少对应用内存的占用。
-
-Stage模型上同名对象覆盖导致问题的场景举例说明。
-
-1. 在UIAbilityA文件中使用globalThis中存放了[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
-
-   export default class UIAbilityA extends UIAbility {
-     onCreate(want, launch) {
-       globalThis.context = this.context; // UIAbilityA存放context到globalThis
-       ...
-     }
-   }
-   ```
-
-2. 在UIAbilityA的页面中获取该[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)并进行使用。使用完成后将UIAbilityA实例切换至后台。
-
-   ```ts
-   @Entry
-   @Component
-   struct Index {
-     onPageShow() {
-       let ctx = globalThis.context; // 页面中从globalThis中取出context并使用
-     }
-     // 页面展示
-     build() {
-       ...
-     }
-   }
-   ```
-
-3. 在UIAbilityB文件中使用globalThis中存放了[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)，并且命名为相同的名称。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
-
-   export default class UIAbilityB extends UIAbility {
-     onCreate(want, launch) {
-       // UIAbilityB覆盖了UIAbilityA在globalThis中存放的context
-       globalThis.context = this.context;
-       ...
-     }
-   }
-   ```
-
-4. 在UIAbilityB的页面中获取该[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)并进行使用。此时获取到的globalThis.context已经表示为UIAbilityB中赋值的[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)内容。
-
-   ```ts
-   @Entry
-   @Component
-   struct Index {
-     onPageShow() {
-       let ctx = globalThis.context; // Page中从globalThis中取出context并使用
-     }
-     // 页面展示
-     build() {
-       ...
-     }
-   }
-   ```
-
-5. 在UIAbilityB实例切换至后台，将UIAbilityA实例从后台切换回到前台。此时UIAbilityA的onCreate生命周期不会再次进入。
-
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
-
-   export default class UIAbilityA extends UIAbility {
-     onCreate(want, launch) { // UIAbilityA从后台进入前台，不会再走这个生命周期
-       globalThis.context = this.context;
-       ...
-     }
-   }
-   ```
-
-6. 在UIAbilityA的页面再次回到前台时，其获取到的globalThis.context表示的为UIAbilityB的[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)，而不是UIAbilityA的[UIAbilityContext](../reference/apis/js-apis-inner-application-uiAbilityContext.md)，在UIAbilityA的页面中使用则会出错。
-
-   ```ts
-   @Entry
-   @Component
-   struct Index {
-     onPageShow() {
-       let ctx = globalThis.context; // 这时候globalThis中的context是UIAbilityB的context
-     }
-     // 页面展示
-     build() {
-       ...
-     }
-   }
-   ```
-
 ## 使用AppStorage/LocalStorage进行数据同步
 
 ArkUI提供了AppStorage和LocalStorage两种应用级别的状态管理方案，可用于实现应用级别和UIAbility级别的数据同步。使用这些方案可以方便地管理应用状态，提高应用性能和用户体验。其中，AppStorage是一个全局的状态管理器，适用于多个UIAbility共享同一状态数据的情况；而LocalStorage则是一个局部的状态管理器，适用于单个UIAbility内部使用的状态数据。通过这两种方案，开发者可以更加灵活地控制应用状态，提高应用的可维护性和可扩展性。详细请参见[应用级变量的状态管理](../quick-start/arkts-application-state-management-overview.md)。
