我试图在Visual Studio 2012(Visual Basic)中使用WebBrowser单击按钮.我做了很多研究,但我能找到的只是点击ID或名称.
这是HTML代码.
<button type='submit' class="btn btn-default" style='float:right'>
Login<i class="gicon-chevron-right"></i>
您需要逐个搜索您的元素.尝试这样的事情：
For Each elem As HtmlElement In wb1.Document.GetElementsByTagName("button")
' Check the attributtes you want
If elem.GetAttribute("class") = "btn btn-default" Then
'Check even the text if you want
If elem.InnerText = "Login" Then
'Invoke your event
elem.InvokeMember("click")
End If
End If
Next
这将搜索文档上的所有按钮元素.您可以通过查看包含具有ID或其他内容的按钮的元素来缩小搜索范围：
Dim myElem As HtmlElement = wb1.Document.GetElementById("myContainerId")
For Each elem As HtmlElement In myElem.GetElementsByTagName("button")
'...
Next
