如何将 parent.postMessage("Hello from child window", "*") 消息捕获到 child

Question

如何在 Xaml 代码后面（Parent window）捕获消息？我的 child window 正在抛出此消息

在childwindow,

function sendMsg() {
                var status = document.getElementById("status");
                if (parent && parent.postMessage) {
                    parent.postMessage("Hello from child window", "*");
                    status.innerText = "Sent message to parent...";
                }
            }

在Parentwindow(xaml.cs),

 private void button1_Click(object sender, RoutedEventArgs e)
        {
            // Get URI to navigate to  
            Uri uri = new Uri("child window url to be opened");            
            // Navigate to the desired URL by calling the .Navigate method  
            this.mybrowser.Navigate(uri);
        }

在Xaml,

 <WebBrowser Name="mybrowser" Margin="339,10,10,10" Height="396"></WebBrowser>
 <Button Content="Send Message to WebView" Margin="10,-700,736,0" Height="20" Click="Button_Click"/>

最后我使用 java 脚本的 window.external 方法和 ObjectForScriptingHelper class.If 我在 class ObjectForScriptingHelper class.Create 中有一个 InvokeMeFromJavascript 方法此 class 的对象并将其传递给 WebBrowser control.This 的属性 ObjectForScripting 有详细说明 http://www.dotnetfunda.com/articles/show/840/working-with-webbrowser-in-wpf
