WebBrowser.ObjectForScripting 设置或者获得一个对象，该对象可以由在WebBrowser控件中的Web页面上的Script COde 访问
注意：
使用该属性，可以在WebBrowser控件所拥有的Web 页面和拥有WebBrowser的应用程式之间通讯。该属性可以让你用客户端应用程式Code来写动态HTML，
为使这个属性有效，须注意Web页面的Script须用window.external来调用，你需要在 ComVisibleAttribute Attribute来标注Class类
例子：
namespace WindowsFormsWebBrowser
{
/// <summary>
/// Form1 as COM
/// </summary>
[ComVisible(true)]
public partial class Form1 : Form
{
private Button button1 = new Button();
private WebBrowser webBrowser1 = new WebBrowser();
public Form1()
{
InitializeComponent();
button1.Text = "call script code from client code";
button1.Dock = DockStyle.Top;
button1.Click += new EventHandler(button1_Click);
webBrowser1.Dock = DockStyle.Fill;
Controls.Add(webBrowser1);
Controls.Add(button1);
Load += new EventHandler(Form1_Load);
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.AllowWebBrowserDrop = false;
webBrowser1.IsWebBrowserContextMenuEnabled = false;
webBrowser1.WebBrowserShortcutsEnabled = false;
webBrowser1.ObjectForScripting = this;//允许使用ObjectForScripting
// Uncomment the following line when you are finished debugging.
webBrowser1.ScriptErrorsSuppressed = true;
// onclick按钮触发Form1的Test方法
webBrowser1.DocumentText =
"<html><head><script>" +
"function hosttest(message) { alert(message); }" +
"</script></head><body><button " +
"onclick="window.external.Test('called from script code')">" +
"call client code from script code</button>" +
"</body></html>";
}
// 允许Web Page ONclick事件调用的方法，window.external.Test()
public void Test(String message)
{
MessageBox.Show(message, "client code");
}
// Button1的Click触发事件，调用web Page的JavaScript Function hosttest
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Document.InvokeScript("hosttest",
new String[] { "called from client code" });
}
}
}
最后运行结果：
