# 元能力子系统JS API变更Changelog

## cl.ability.1 AreaMode接口变更
AreaMode接口有多个重复，删除掉重复的AreaMode。

**变更影响**

影响API9版本的JS接口，应用需要进行适配才可以在新版本SDK环境正常实现功能。

**关键的接口/组件变更**

| 模块名                    | 类名                | 方法/属性/枚举/常量                                          | 变更类型 |

| @ohos.app.ability.common.d.ts | common.AreaMode |  | 删除     |
| application/Context.d.ts | AreaMode |  | 删除     |


**适配指导**

使用@ohos.app.ability.contextConstant.d.ts中的AreaMode

```ts
import contextConstant from '@ohos.app.ability.contextConstant';
let area: contextConstant.AreaMode = contextConstant.AreaMode.EL1;
```



## cl.ability.2 killProcessesBySelf接口变更

killProcessesBySelf接口命名不合理，修改为killAllProcesses。

let appContext = context.getApplicationContext();
appContext.killProcessesBySelf()
```

变更后代码：

```ts
let context: common.UIAbilityContext = globalThis.abilityContext;

      num: 1
      constructor(name, str) {
        this.name = name;
        this.str = str;
      }
      marshalling(messageParcel) {
          messageParcel.writeInt(this.num);
          messageParcel.writeString(this.str);
          console.log('MyMessageAble marshalling num[' + this.num + '] str[' + this.str + ']');
          return true;
      }
      unmarshalling(messageParcel) {
          this.num = messageParcel.readInt();
          this.str = messageParcel.readString();
          console.log('MyMessageAble unmarshalling num[' + this.num + '] str[' + this.str + ']');
          return true;
      }
  };
  let method = 'call_Function';
  function funcCallBack(pdata) {
      console.log('Callee funcCallBack is called ' + pdata);
      let msg = new MyMessageAble("test", "");
      pdata.readSequenceable(msg);
      return new MyMessageAble("test1", "Callee test");
  }
  export default class MainUIAbility extends UIAbility {
    onCreate(want, launchParam) {
      console.log('Callee onCreate is called');
      try {
        this.callee.on(method, funcCallBack);
      } catch (error) {
        console.log('Callee.on catch error, error.code: ' + error.code +
          ' error.message: ' + error.message);
      }
    }
  }
```

变更后代码：

```ts
  class MyMessageAble{
      name:""
      str:""
      num: 1
      constructor(name, str) {
        this.name = name;
        this.str = str;
      }
      marshalling(messageSequence) {
          messageSequence.writeInt(this.num);
          messageSequence.writeString(this.str);
          console.log('MyMessageAble marshalling num[' + this.num + '] str[' + this.str + ']');
          return true;
      }
      unmarshalling(messageSequence) {
          this.num = messageSequence.readInt();
          this.str = messageSequence.readString();
          console.log('MyMessageAble unmarshalling num[' + this.num + '] str[' + this.str + ']');
          return true;
      }
  };
  let method = 'call_Function';
  function funcCallBack(pdata) {
      console.log('Callee funcCallBack is called ' + pdata);
      let msg = new MyMessageAble("test", "");
      pdata.readParcelable(msg);
      return new MyMessageAble("test1", "Callee test");
  }
  export default class MainUIAbility extends UIAbility {
    onCreate(want, launchParam) {
      console.log('Callee onCreate is called');
      try {
        this.callee.on(method, funcCallBack);
      } catch (error) {
        console.log('Callee.on catch error, error.code: ' + error.code +
          ' error.message: ' + error.message);
      }
    }
