示例

下面的代码示例演示如何在为 Windows 8 编译的应用中使用 ScriptNotify 事件。 从 Windows 8.1 开始，省略与 AllowedScriptNotifyUris 相关的行。 有关详细信息，请参阅 WebView 类概述。

public MyPage()
{
    this.InitializeComponent();
    MyWebView.ScriptNotify += MyWebView_ScriptNotify;

    // Here we have to set the AllowedScriptNotifyUri property because we are 
    // navigating to some site where we don't own the content and we want to 
    // allow window.external.notify() to pass data back to the app.
    List<Uri> allowedUris = new List<Uri>();
    allowedUris.Add(new Uri("http://www.bing.com"));
    MyWebView.AllowedScriptNotifyUris = allowedUris;
}

void MyWebView_ScriptNotify(object sender, NotifyEventArgs e)
{
    // Respond to the script notification.
}
