涵盖了几种常用的 webBrowser执行javascript的方法，详见示例截图以及代码
execScript方式:
using mshtml;
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 WebBrowser_Script
{
public partial class execScriptForm : Form
{
public execScriptForm()
{
InitializeComponent();
}
private void btnOpen_Click(object sender, EventArgs e)
{
this.webBrowser1.Navigate(this.txtUrl.Text);
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
IHTMLDocument2 Doc2 = (IHTMLDocument2)webBrowser1.Document.DomDocument;
if (Doc2.parentWindow != null)
{
string order = " alert('这里可以执行页面中存在的任意函数' document.body.innerHTML); ";
//MessageBox.Show(order);
Doc2.parentWindow.execScript(order, "JavaScript");
}
}
}
}
NavigateScript方式:
其中需要作如下设置
由于visual studio2005 中WebBrowser控件已经实现了IDocHostUIHandler,所以
只要把应用程序属性类的 “com可见”选上.
再给 this.webBrowser1.ObjectForScripting = this; 赋值就行了
:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Windows.Forms;
namespace WebBrowser_Script
{
[ComVisible(true)]
public partial class NavigateScriptForm : Form
{
public NavigateScriptForm()
{
InitializeComponent();
}
private void btnOpen_Click(object sender, EventArgs e)
{
this.webBrowser1.Navigate(this.txtUrl.Text);
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
webBrowser1.Navigate(@"javascript:
function alert(str)
{
window.external.alertMessage(str);
}");
webBrowser1.ObjectForScripting = this;
}
public void alertMessage(string s)
{
MessageBox.Show(s, "这是自定义的title，呵呵呵");
}
private void NavigateScriptForm_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText = @"
<html>
<input type=""button"" value=""测试"" onclick=""alert('好例子网 路过');"">
</html>
";
}
}
}
InvokeScript方式：
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 WebBrowser_Script
{
public partial class InvokeScriptForm : Form
{
public InvokeScriptForm()
{
InitializeComponent();
this.webBrowser1.Navigate(this.txtUrl.Text);
}
private void btnOpen_Click(object sender, EventArgs e)
{
var input = this.webBrowser1.Document.GetElementById("kw");
input.SetAttribute("value", "好例子网");
var button = this.webBrowser1.Document.GetElementById("su");
button.InvokeMember("click");
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
}
}
}
另外:InvokeScript 还可以带参数的形式执自定义行脚本方法
例如: webBrowser1.Document.InvokeScript(“getPwd“, new object[] { “18780110000“ })
