Contoh

Contoh kode berikut menunjukkan penggunaan peristiwa ScriptNotify di aplikasi yang dikompilasi untuk Windows 8. Dimulai dengan Windows 8.1, hilangkan baris yang terkait dengan AllowedScriptNotifyUris. Untuk informasi selengkapnya, lihat gambaran umum kelas WebView .

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.
}
