WebBrowser 中 HTML 元素如何觸發 WinForm 事件

這個問題來自論壇提問，對 DOM 稍微了解的話還是比較簡單的，只要註冊一下事件就可以了。

C# 程式碼如下：

using System;
using System.ComponentModel;
using System.Windows.Forms;

namespace WindowsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.webBrowser1.Navigate("");
            this.webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
        }

        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (e.Url.ToString() != this.webBrowser1.Url.ToString()) return;
            foreach (System.Windows.Forms.HtmlElement el in this.webBrowser1.Document.GetElementsByTagName("input"))
            {
                if (el.Name == "btnG")
                {
                    el.Click += new HtmlElementEventHandler(Form1_Click);
                }
            }
        }

        void Form1_Click(object sender, HtmlElementEventArgs e)
        {
            MessageBox.Show("jinjazz pass");
        }
    }
}
