在vb中呼叫javascript功能函式並將結果反映到WebBrowser上
控制網頁的FORMS行為
Private Sub Command2_Click()
With WebBrowser1.Document.Forms(0)
.c2.Checked = 1
.r1(1).Checked = 1
End With
End Sub
Private Sub Command2_Click()
With WebBrowser1.Document.Forms(0)
.d1.Options(1).Selected = 1
End With
End Sub
web.Document.getElementsByName("D1").Item(0).selectedIndex = 1

<input type="radio" value="n" checked name="notecome">普通
<input type="radio" value="c" name="notecome">原創
<input type="radio" value="z" name="notecome">轉帖
<input type="button" value="傳送提交" name="button"
比如一個網頁裡有如上程式碼
我想選擇原創
webbrowser中怎麼寫
Private Sub Command1_Click()
WebBrowser1.Navigate "c:/ggg.html"
End Sub
Private Sub Command2_Click()
Dim x
For Each x In WebBrowser1.Document.All("notecome")
If x.Value = "c" Then
x.Checked = True
End If
Next
End Sub
============================================================================================
假設你的HTML程式碼如下：
<html>
<script>
function abcd(){
alert("haha");
return false;
}
</script>
<body>
<a id = 'xxx' href=# onclick="abcd()">ggggg</a>
</body>
</html>
VB程式碼如下：
Private Sub Command1_Click()
WebBrowser1.Navigate "http://www.applevb.com/script_test.html"
End Sub
Private Sub Command2_Click()
Dim a, b
Dim d As IHTMLDocument2
For Each a In WebBrowser1.Document.All
Debug.Print a.tagName
If (a.tagName = "SCRIPT") Then
End If
If (a.tagName = "A") Then
If a.Id = "xxx" Then
a.FireEvent ("onclick")
End If
End If
Next
點選Command1瀏覽這個網頁，點選Command2執行其中的指令碼abcd。

怎麼程式設計把使用者名稱，密碼提交到網頁上的登入頁？
首先在程式中加入Webbrowser控制元件並加入引用 Microsoft HTML Object Library。
假設你的HTML頁面表單程式碼如下：
<form method="POST" action="http://chen/dll/chat/chatmain.exe/RegUser">
<p>請填寫下面表單註冊（*項為必添項）</p>
<p>*姓名<input type="text" name="Name" size="20"></p>
<p>*暱稱<input type="text" name="NickName" size="20"></p>
<p>電子郵件<input type="text" name="EMail" size="20"></p>
<p>*密碼<input type="text" name="Password" size="20"></p>
<p><input type="submit" value="提交" name="B1"><input type="reset" value="全部重寫" name="B2"></p>
</form>
注意其中元素的type、Name、value屬性。然後VB中的程式碼如下：
Private Sub Command1_Click()
WebBrowser1.Navigate "http://chen/chat/newuser.htm"
End Sub
Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Dim vDoc, vTag
Dim i As Integer
Set vDoc = WebBrowser1.Document
List1.Clear
For i = 0 To vDoc.All.length - 1
If UCase(vDoc.All(i).tagName) = "INPUT" Then
Set vTag = vDoc.All(i)
If vTag.Type = "text" Or vTag.Type = "password" Then
List1.AddItem vTag.Name
Select Case vTag.Name
Case "Name"
vTag.Value = "IMGod"
Case "NickName"
vTag.Value = "IMGod"
Case "Password"
vTag.Value = "IMGodpass"
Case "EMail"
vTag.Value = "
End Select
ElseIf vTag.Type = "submit" Then
vTag.Click
End If
End If
Next i
End Sub
點選Command1就可以自動填表並提交了。

呼叫forms下的Submit控制元件的Click事件,我會做,但我不想這麼做.
有沒有辦法直接呼叫類似於:web1.document.forms.submit,這句語句我怎麼寫都不成功
是這個
Webbrowser1.document.formName.submit()
不能用,formname為form1所以我呼叫Webbrowser1.document.form1.submit
出錯型別:物件不支援該屬性或方法,
然後呼叫Webbrowser1.document.forms(0).submit()
出錯型別同上
Private Sub Command1_Click()
WebBrowser1.Navigate "http://localhost/webapplication2/MyLogonPage.aspx"
End Sub
Private Sub Command2_Click()
WebBrowser1.Document.All("Form1").submit
End Sub
<form name="form1" method="post" action="aa.asp">
......
<input name="reset" type="reset" vlaue="reset" class="button">
</form>
我本想把reset的type改成submit 再提交,可出錯,type是隻讀屬性,不能修改,我只要有辦法把這頁面遞交出去就行,當然,用POST也不行,引數太多,組合方式太多
