如何通过 JavaScriptProxy 代理机制在鸿蒙应用中实现 JS 调用 ArkUI 主进程的拨打电话功能？
尝试：
typescript
Copy
// ArkUI侧注册代理
webview.registerJavaScriptProxy({
callPhoneNumber: (number: string) => {
call.makeCall(number); // 调用系统电话接口}
}, "JSBridge");
// JS侧调用
window.JSBridge.callPhoneNumber("123456");
期望结果：
验证 JS 调用后能否正确触发系统拨号界面，并统计接口调用耗时（目标 < 50ms）。
ets:
import { call } from '@kit.TelephonyKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { webview } from '@kit.ArkWeb';
class TestObj {
constructor() {
}
startCallDialog(phoneNumber: string): void {
let isSupport = call.hasVoiceCapability();
if (!isSupport) {
console.error('Not support voice capability.');
return;
}
call.makeCall(phoneNumber, (err: BusinessError) => {
if (err) {
console.error(
Failed to make call. Code is ${err.code}, Message is ${err.message});return;
}
console.info('Succeeded in making call.');
})
}
}
