控制网页的FORMS行为
Private Sub Command2_Click() With WebBrowser1.Document.Forms(0) .c2.Checked = 1 .r1(1).Checked = 1 End WithEnd Sub
Private Sub Command2_Click() With WebBrowser1.Document.Forms(0) .d1.Options(1).Selected = 1 End WithEnd 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">原创<input type="radio" value="z" name="notecome">转帖<input type="button" value="发送提交" name="button"
比如一个网页里有如上代码我想选择原创webbrowser中怎么写
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 NextEnd Sub
============================================================================================假设你的HTML代码如下：
<html><script> function abcd(){ alert("haha"); return false; }</script>
<body> <a id = 'xxx' href=# οnclick="abcd()">ggggg</a></body></html>
VB代码如下：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
点击Command1浏览这个网页，点击Command2运行其中的脚本abcd。

怎么编程把用户名，密码提交到网页上的登录页？首先在程序中加入Webbrowser控件并加入引用 Microsoft HTML Object Library。假设你的HTML页面表单代码如下：<form method="POST" action="http://chen/dll/chat/chatmain.exe/RegUser"> <p>请填写下面表单注册（*项为必添项）</p> <p>*姓名<input type="text" name="Name" size="20"></p> <p>*昵称<input type="text" name="NickName" size="20"></p> <p>电子邮件<input type="text" name="EMail" size="20"></p> <p>*密码<input type="text" name="Password" size="20"></p> <p><input type="submit" value="提交" name="B1"><input type="reset" value="全部重写" name="B2"></p></form>注意其中元素的type、Name、value属性。然后VB中的代码如下：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 = "IMGod@paradise.com" End Select ElseIf vTag.Type = "submit" Then vTag.Click End If End If Next iEnd Sub点击Command1就可以自动填表并提交了。
=====================================================================================调用forms下的Submit控件的Click事件,我会做,但我不想这么做.
有没有办法直接调用类似于:web1.document.forms.submit,这句语句我怎么写都不成功是这个Webbrowser1.document.formName.submit()
不能用,formname为form1所以我调用Webbrowser1.document.form1.submit出错类型:对象不支持该属性或方法,然后调用Webbrowser1.document.forms(0).submit()出错类型同上Private Sub Command1_Click() WebBrowser1.Navigate "http://localhost/webapplication2/MyLogonPage.aspx"End Sub
Private Sub Command2_Click() WebBrowser1.Document.All("Form1").submitEnd 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,可出错,type是只读属性,不能修改,我只要有办法把这页面递交出去就行,当然,用POST也不行,参数太多,组合方式太多
你用下面的代码试一下你的页面：
Private Sub Command1_Click() WebBrowser1.Navigate "http://oakhome.xicp.net/webapplication2/MyLogonPage.aspx"End Sub
Private Sub Command2_Click() Dim x On Error Resume Next For Each x In WebBrowser1.Document.All List1.AddItem x.Name NextEnd Sub
看看在List1里面列出来的页面元素的名字有没有Form1找到原因了,你的页面是这样的:<input language="javascript" οnclick="if (typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); " name="Submit1" id="Submit1" type="submit" value="Submit" />你把name="Submit1" 改成name="Submit"肯定就不会成功了,很不幸的是我要提交的页面中就有这样一句,现在可有办法解决吗???
=======================================================================使用WebBrowser_V1接受消息
Private WithEvents WebMessage As WebBrowser_V1
Private Sub Form_Load() Set WebMessage = WebBrowser1.ObjectEnd Sub
Private Sub WebMessage_NewWindow(ByVal URL As String, ByVal Flags As Long, ByVal TargetFrameName As String, PostData As Variant, ByVal Headers As String, Processed As Boolean)
'这里有Flags变量可以取得窗体应有的状态
End Sub
具体值需要你自己去试试看。对象浏览器里面没有
=======================================================================================================
通过下面的方法遍历页面中的IFrame：
Sub EnumFrames(ByVal wb As WebBrowser)Dim pContainer As olelib.IOleContainerDim pEnumerator As olelib.IEnumUnknownDim pUnk As olelib.IUnknownDim pBrowser As SHDocVw.IWebBrowser2
Set pContainer = wb.Object.Document ' Get an enumerator for the frames If pContainer.EnumObjects(OLECONTF_EMBEDDINGS, pEnumerator) = 0 Then Set pContainer = Nothing ' Enumerate and refresh all the frames Do While pEnumerator.Next(1, pUnk) = 0 On Error Resume Next ' Clear errors Err.Clear ' Get the IWebBrowser2 interface Set pBrowser = pUnk If Err.Number = 0 Then Debug.Print "Frame: " & pBrowser.LocationURL End If Loop Set pEnumerator = Nothing End If End Sub
=======================================================================================
