HarmonyOS ArkWeb 嵌入H5页面，原有的功能未能实现

1.对于第一个问题请参考以下代码：

// xxx.ets
import web_webview from '@ohos.web.webview';
import call from '@ohos.telephony.call';

@Entry
@Component
struct WebComponent {
  webviewController: web_webview.WebviewController = new web_webview.WebviewController();

  build() {
    Column() {
      Web({ src: $rawfile('call.html'), controller: this.webviewController })
        .onLoadIntercept((event) => {
          if (event) {
            let url: string = event.data.getRequestUrl();
            // 判断链接是否为拨号链接
            if (url.indexOf('tel://') === 0) {
              // 跳转拨号界面
              call.makeCall(url.substring(6), (err) => {
                if (!err) {
                  console.info('make call succeeded.');
                } else {
                  console.info('make call fail, err is:' + JSON.stringify(err));
                }
              });
              return true;
            }
          }
          return false;
        })
    }
  }
}
