+
+connectServiceExtensionAbility(want: Want, options: ConnectOptions): number;
+
+将一个Ability与服务类型的Ability绑定。
+
+**系统能力**：SystemCapability.Ability.Form
+
+**系统API**: 此接口为系统接口，三方应用不支持调用。
+
+**参数：**
+
+| 参数名 | 类型 | 必填 | 说明 |
+| -------- | -------- | -------- | -------- |
+| want | [Want](js-apis-application-want.md)  | 是 | Want类型参数，传入需要启动的ability的信息，如Ability名称，Bundle名称等。 |
+| options | [ConnectOptions](js-apis-inner-ability-connectOptions.md) | 是 | ConnectOptions类型的回调函数，返回服务连接成功、断开或连接失败后的信息。 |
+
+**返回值：**
+
+| 类型 | 说明 |
+| -------- | -------- |
+| number | 返回一个connectId，后续根据此connectId断开连接。 |
+
+**错误码：**
+
+| 错误码ID | 错误信息 |
+| ------- | -------------------------------- |
+| 16000001 | The specified ability does not exist. |
+| 16000002 | Incorrect ability type. |
+| 16000004 | Can not start invisible component. |
+| 16000006 | Cross-user operations are not allowed. |
+| 16000008 | The crowdtesting application expires. |

+
+  let commRemote = null;
+  export default class MyFormExtensionAbility extends FormExtensionAbility {
+    onFormEvent(formId, message) {
