VB net 单击网页上的选项卡按钮

Question

这是全新的，我无法让我的代码单击并激活网页上的选项卡按钮，我尝试激活的网站部分是

class="tabButton EngagementsHistoryTable"

"网络历史">

<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>

下面的代码执行单击，但没有任何反应。

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

Answer 1

感谢您的 CruleD，我通过执行以下操作使其正常工作

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

Answer 2

当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

与卡尔相比

<td class=" ui-datepicker-week-end  ui-datepicker-current-day" data-handler="selectDay" data-event="click" data-month="5" data-year="2018"><a class="ui- 
state-default ui-state-active ui-state-hover" href="#">24</a></td>

飞往卡尔

<td class=" ui-datepicker-days-cell-over  ui-datepicker-current-day ui-datepicker today" data-handler="selectDay" data-event="click" data-month="6" data-year="2018"><a 
class="ui-state-default ui-state-highlight ui-state-active" href="#">4</a></td>
