範例

下列程式碼範例示範如何在針對 Windows 8 編譯的應用程式中使用 ScriptNotify 事件。 從 Windows 8.1 開始，請省略與 AllowedScriptNotifyUris相關的行。 如需詳細資訊，請參閱 WebView 類別概觀。

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.
}
