webview中能只通过location.href直接拉起电话吗

// 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; 
        }) 
    } 
  } 
}
