此示例展示了从 javascript 到 C# 通信的两种不同方式。第一种方法是使用（哈顿方法）消息泵。第二种方法是使用javascript 更改location当前文档并使用C# 处理和取消导航。示例 HTML：<html><body></body><script type='text/javascript'>         /* Begin (Hatton) method of communicating from javascript to C# */    alert('javascript : about call message C# (Hatton) method');    event = document.createEvent('MessageEvent');    var origin = window.location.protocol + '//' + window.location.host;    event.initMessageEvent ('callMe', true, true, 'some data', origin, 1234, window, null);    document.dispatchEvent (event);                             alert('javascript : message sent to C# (Hatton) method');    /* End (Hatton) method of communicating from javascript to C# */    /* Begin javascript changing location.href method */    alert('javascript : about call message C# location changed method');    location.href='http://somehost//someevent.php?somedata';    alert('javascript : message sent to C# location changed method');    /* End javascript changing location.href method */</script></html>Example.cs 代码：using System;using System.IO;using System.Windows.Forms;using Gecko;    namespace Example6{    static class Example6    {        private static GeckoWebBrowser _browser;                [STAThread]        static void Main()        {            // Don't use XULRunnerLocator.GetXULRunnerLocation() in production software.            string firefox14Path = XULRunnerLocator.GetXULRunnerLocation();            Xpcom.Initialize(firefox14Path);            var form = new Form();            _browser = new GeckoWebBrowser { Dock = DockStyle.Fill };            _browser.Navigating += InstallCustomEventListener;            _browser.Navigating += ListenForFakeNavigationMessages;            _browser.Navigate("file://" + Path.Combine(Environment.CurrentDirectory, "Example6.html"));            form.Controls.Add(_browser);            Application.Run(form);        }        #region Hatton method        static void InstallCustomEventListener(object sender, GeckoNavigatingEventArgs e)        {            _browser.Navigating -= InstallCustomEventListener;            _browser.AddMessageEventListener("callMe", ((string p) =>                MessageBox.Show(String.Format("C# : Got Message '{0}' from javascript", p))));        }        #endregion        #region location changed method        static void ListenForFakeNavigationMessages(object sender, GeckoNavigatingEventArgs e)        {            const string id = "http://somehost//someevent.php?";            var uri = e.Uri.AbsoluteUri;            if (uri.Contains(id))            {                MessageBox.Show(String.Format("C# : Got Message '{0}' from javascscript", uri.Substring(id.Length)));                // This is a fake navigating event - cancel it.                e.Cancel = true;            }        }        #endregion    }}
