对编写脚本熟悉的读者都知道页面中可以添加脚本响应元素的事件，例如超链接的OnClick事件，图片的OnMouseMove事件，我们也可以使VB程序响应这些事件。下面是一个VB响应页面中按钮的Click事件的代码：
首先建立一个新工程，在Form1中加入一个Webbrowser控件，然后在Form1中加入以下代码： Option Explicit Public Sub Some_Procedure()
MsgBox "你点击了按钮."
End Sub Private Sub Form_Load()
'下载空页面
WebBrowser1.Navigate2 "about:blank"
End Sub Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
'建立事件响应类
Dim cfForward As clsForward '定义在浏览器中显示的HTML代码，其中包含一个按钮btnMyButton
Dim sHTML As String
sHTML = "<P>This is some text.</P>"
sHTML = sHTML & "<P>And here is a button.</P>"
sHTML = sHTML & "<BUTTON ID=btnMyButton>"
sHTML = sHTML & "Click this button.</BUTTON>" '将HTML代码写入浏览器
WebBrowser1.Document.body.innerHTML = sHTML '将事件响应类连接到页面的按钮btnMyButton上
Set cfForward = New clsForward
cfForward.Set_Destination Me, "Some_Procedure"
WebBrowser1.Document.All("btnMyButton").onclick = cfForward
End Sub 向工程中添加一个Class Module，Class Module的Name属性设定为clsForward，在clsForward中添加以下代码： Option Explicit Dim oObject As Object
Dim sMethod As String
Dim bInstantiated As Boolean Private Sub Class_Initialize()
bInstantiated = False
End Sub Public Sub Set_Destination(oInObject As Object, sInMethod As String)
Set oObject = oInObject
sMethod = sInMethod
bInstantiated = True
End Sub Public Sub My_Default_Method()
If bInstantiated Then
CallByName oObject, sMethod, VbMethod
End If
End Sub 运行程序，点击Webbrowser中的“Click this button”按钮。程序就会弹出消息框提示“你点击了按钮.”
网页中的响应click或mousedown mouseup事件的原代码如下：（把它放到WebBrowser中一样的），但是如果你要在网页中触发VB的click或mousedown mouseup事件是不可能的<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<TITLE></TITLE>
<SCRIPT  LANGUAGE=javascript>

</SCRIPT>
</HEAD>
<BODY LANGUAGE=javascript onload="return window_onload()"><P><INPUT id=button1 type=button value=Button name=button1 LANGUAGE=javascript onclick="return button1_onclick()" onmouseup="return button1_onmouseup()" onmousedown="return button1_onmousedown()"></P>
<div id=infoDiv></div>
</BODY>
</HTML>
<A href="http://www.sina.com">sina</A>加在<body>下就是超链接了
TechnoFantasy的方法我试过了，没有用嘛。
