硒-無法單擊元素c＃

Question

我有一個單擊樹的所有節點元素並驗證新頁面標題的測試。 我可以單擊除一個元素之外的每個元素。 該元素存在，我可以用鼠標單擊它，但是我無法通過測試單擊它，它也不會失敗。 任何幫助將不勝感激！

測試中存在問題的部分（使用了我沒有問題的元素來驗證懸停功能是否正常工作）：

IWebElement othernode = IWebDriverExtensions.FindElement(By.Id("node122")); // another element, this one functions properly
HandleMouseHoverEvent(othernode); // hover over functioning element - this is successful
IWebDriverExtensions.wait();

IWebElement findme = IWebDriverExtensions.FindElement(By.Id("node100015")); // element I want to click on
Console.WriteLine("displayed " + findme.Displayed); // check if wanted element is displayed - returns True
Console.WriteLine(findme.Text); // prints text successfully
HandleMouseHoverEvent(findme); // hover over the element I want to click on - this doesn't work, but does not error
IWebDriverExtensions.wait();
findme.Click(); // click on the element I want to click on - this doesn't work, but does not error
Console.WriteLine("clicked"); // this gets printed

輸出：

displayed True
New Prospect & Assignment
clicked

這是兩個元素（node122有效，node100015無效）：

<tr nodetype="child" nodesequence="122">
    <td></td>
    <td colspan="2"><span>&nbsp;&nbsp;</span><span id="node122" onclick="try{UpdateNodes(event, this, 'RedirectTab','Interest/Project','action.aspx?treestate=-14-&amp;PageId=50&amp;AppId=10&amp;idnumber=000&amp;AppHeaderName=Prospect+Tracking++-+Interest%2fProject&amp;SelectedNodeSequence=122','Default.aspx?treestate=-14-&amp;PageId=50&amp;AppId=10&amp;idnumber=000&amp;AppHeaderName=Prospect+Tracking++-+Interest%2fProject&amp;SelectedNodeSequence=122', 1)} catch(exp){ }" onmouseout="OnNodeMouseOut(event, this, 1)" onmouseover="OnNodeMouseOver(event, this)" class="menuchild" lvl="1">Interest/Project</span><span></span></td>
</tr>
<tr nodetype="child" nodesequence="100015">
    <td></td>
    <td colspan="2"><span>&nbsp;&nbsp;</span><span id="node100015" onclick="try{UpdateNodes(event, this, 'RedirectTab','New Prospect &amp; Assignment','action.aspx?treestate=-14-&amp;PageId=50&amp;AppId=80&amp;idnumber=000&amp;AppHeaderName=Prospect+Tracking++-+New+Prospect+%26+Assignment&amp;SelectedNodeSequence=100015','Default.aspx?treestate=-14-&amp;PageId=50&amp;AppId=80&amp;idnumber=000&amp;AppHeaderName=Prospect+Tracking++-+New+Prospect+%26+Assignment&amp;SelectedNodeSequence=100015', 1)} catch(exp){ }" onmouseout="OnNodeMouseOut(event, this, 1)" onmouseover="OnNodeMouseOver(event, this)" class="menuchild" lvl="1">New Prospect &amp; Assignment</span><span></span></td>
</tr>

確保您要檢查的元素具有單個匹配項。

如果在沒有給出任何例外的情況下無法正常點擊，我們可以使用以下方法進行點擊。

1. var button = document.getElementById("....");
   button.click(); 

2. Actions action = new Actions(_driver);  
  action.MoveToElement(driver.FindElement(By.Id(".....")));
  action.Click().Build().Perform();
