c#和javascript函数相互调用示例分享

[ComVisible(true)]
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        protected override void OnLoad(EventArgs e)
        {
            webBrowser1.ObjectForScripting = this;
            webBrowser1.Navigate("https://www.jb51.net");
            base.OnLoad(e);
        }
    }

<scripttype="text/javascript">     //提供给c#调用的方法   
 function test(n,s){        
    alert(n+"/"+s);   
 }     //调用C#的方法    
function callCSharp(){         //这里可以看到window.external被设置成了什么       
 alert(window.external);       
 window.external.Test("hello",15);    
}
</script>
<button onclick="callCSharp()">call c#</button>

调用：web.Document.InvokeScript("test", new Object[] {1,"hello"});
