Question

这完全陌生，我无法获取代码来单击并激活网页上的tabbutton，我要激活的网站部分是

class =“ tabButton EngagementsHistoryTable”

“网络历史记录”

<ul class="tabs_manager_buttons_container lpview_tabs_manager_buttons_container">
   <li class="lpview_underLine underLine" style="left: 0px; width: 132px; 
   display: block;"></li>
 <li class="tabButton VisitorListTable first active">
    <span class="lpview_tabButton tabButtonText" title="Web Visitors" 
     tooltip-align="left" tooltip-delay="1500" tooltip-text="Web Visitors">Web 
     Visitors</span></li>
 <li class="tabButton EngagementsHistoryTable">
    <span class="lpview_tabButton tabButtonText" title="Web History" tooltip- 
     align="left" tooltip-delay="1500" tooltip-text="Web History">Web 
     History</span> 
 </li>
<li class="tabButton AgentListTable"><span class="lpview_tabButton 
     tabButtonText" title="Agents" tooltip-align="left" tooltip-delay="1500" 
     tooltip-text="Agents">Agents</span></li>
</ul>

下面的代码执行点击，但是什么也没发生。

 For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("li")
    If element.GetAttribute("className") = "tabButton EngagementsHistoryTable" Then
           element.InvokeMember("click")
    End If
 Next

感谢CruleD，我可以通过执行以下操作来使其工作

    For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("span")
        If element.GetAttribute("className") = "lpview_tabButton tabButtonText" Then
            If element.GetAttribute("InnerText") = "Web History" Then
                element.InvokeMember("click")
            End If
        End If
    Next

通过类似方法调用日历时

      For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("span")
            If element.GetAttribute("className") = "filterButton lpview_filterButton EngagementsHistoryTableViewController_filterId6 filter_on" Then
                element.InvokeMember("click")
            End If
      Next
