这是HTML,它被保存在一个字符串资源:WebBrowser控件外部脚本不工作
<!DOCTYPE html>
<html>
<head></head>
<body>
<script>
(function(){
window.external.hello()
})()
</script>
</body>
</html>
这是Form1.cs中的内容:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace JSIE
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.Navigate("about:blank");
webBrowser1.Document.Write(String.Empty);
webBrowser1.Document.Write(Properties.Resources.DDocument);
webBrowser1.ObjectForScripting = new JSCallbacks();
}
}
}
,这是JSCallbacks.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Permissions;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace JSIE
{
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[ComVisible(true)]
public class JSCallbacks
{
public void hello() {
MessageBox.Show("Hello, world!");
}
}
}
当我运行它,它不能在JavaScript访问hello()
方法对象,并给我一个脚本错误消息框。我尝试使用this
作为ObjectForScripting
,但它也不起作用。

好的,这很奇怪。出于某种原因,当我从'
