C#中webbrowser控件的使用
各位大侠,你们好!
我遇到一个问题,就是用webbrowser控件调用另外WEB服务器的网页时,其中网页上某个按钮产生相应的事件能向webbrowser控件所在的窗口传递参数值。这个问题怎么解决?
[解决办法]
MSDN上的例子:如何:在 DHTML 代码和客户端应用程序代码之间实现双向通信

using System;
using System.Windows.Forms;
using System.Security.Permissions;

[PermissionSet(SecurityAction.Demand, Name="FullTrust")]
[System.Runtime.InteropServices.ComVisibleAttribute(true)]
public class Form1 : Form
{
private WebBrowser webBrowser1 = new WebBrowser();
private Button button1 = new Button();

[STAThread]
public static void Main()
{
Application.EnableVisualStyles();
Application.Run(new Form1());
}

public Form1()
{
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;
// Uncomment the following line when you are finished debugging.
//webBrowser1.ScriptErrorsSuppressed = true;

webBrowser1.DocumentText =
"<html><head><script>" +
"function test(message) { alert(message); }" +
"</script></head><body><button " +
"onclick=\"window.external.Test('called from script code')\">" +
"call client code from script code</button>" +
"</body></html>";
}

public void Test(String message)
{
MessageBox.Show(message, "client code");


}

private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Document.InvokeScript("test",
new String[] { "called from client code" });
}

}
