推荐答案

有没有内置的浏览器 window.alert Windows Phone中，但你可以绑定一条如下调用 WebBrowser.ScriptNotify

There is no built-in browser window.alert in Windows Phone, but you can bind one as follows to call WebBrowser.ScriptNotify

//inside the page
window.alert = function (__msg) { window.external.notify(' + __msg + '); };


// in your C# code
this.webBrowser.ScriptNotify += new EventHandler<NotifyEventArgs>(Browser_ScriptNotify);
void Browser_ScriptNotify(object sender, NotifyEventArgs e)
{
     MessageBox.Show(e.Value);
}

//later 
this.CordovaView.Browser.IsScriptEnabled = true;
this.CordovaView.Browser.InvokeScript("alert", "ok");

在科尔多瓦，也有一个通知插件，您可以通过

On Cordova, there is also a Notification Plugin that you can plug by

window.alert = navigator.notification.alert;

只要确保能够在config.xml中通知插件

Just be sure to enable Notification Plugin in config.xml

  <feature name="Notification">
      <param name="wp-package" value="Notification"/>
  </feature>
