导读：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 With End Sub Private Sub Command2_Click() With WebBrowser1.Document.Forms(0) .d1.Options(1).Selected = 1 End With En

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 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 Next End Sub ============================================================================================ 假设你的HTML代码如下： <html> <script> function abcd(){ alert("haha"); return false; } </script> <body> <a id = 'xxx' href=# onclick="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 i End 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").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
