C# Winform与JS交互

一、C#调用JS函数

1.JS代码

< script language = "javascript" >
function Hello(msg)
{
    alert('我是JS函数，参数是：' + msg);
    return;
}
< / script >

2.C#代码调用

public class Form1:Form
{
	public Form1()
	{
		InitializeComponent();

		string pathName = Application.StartupPath + "\\" + "HTMLPage1.htm";
		this.webBrowser1.ObjectForScripting = this;
		webBrowser1.Navigate(pathName);
	}

	public void Test()
	{
	　　//调用的函数：
	　　webBrowser1.Document.InvokeScript("Hello", new string[] {"ssss"});
	}
}

二、JS调用C#函数

1.C#函数

using System.Security.Permissions;

//注意： 类定义前需要加上下面两行，否则调用失败！当前类可以com组件的形式供外部调用
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[System.Runtime.InteropServices.ComVisible(true)]
public class Form1: Form
{
	public Form1()
	{
		InitializeComponent();
	}

	public void ShowMessage(string msg)
	{
		MessageBox.Show("我是Winform函数，参数是：" + msg);
	}
}

2.JS里的调用

< script language = "javascript" >
function InvokeFunc()
{
    window.external.ShowMessage("呵呵");
}
< /script >
