Question

我正在尝试使用Xpath和CSS在Selenium Webdriver中找到以下链接。

<table width="100%" cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr>
<tr>
<td class="cspbItmA">
<a class="cspbItm" target="_parent" href="../isp_track.asp?PARENT_MENU=Customer Order">Find Order</a>
</td>
</tr>

但是这些选项都没有，我无法运行脚本并被困在以下异常中：

driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

driver.findElement(By.xpath(".//*[@id='cspbGrp0']/table/tbody/tr[2]/td/a")) .click();

请你帮我解决这个问题。

Answer 1

我的偏好是使用css而不是xpath，我通常会编写自己的选择器。因为它在表格中可能有点棘手（意味着您可能需要进一步遍历）但是从屏幕上的信息中我可以选择以下内容：

//by href
driver.findElement(By.cssSelector("a[href='../isp_track.asp?PARENT_MENU=Customer Order']"))

OR

//by class
driver.findElement(By.cssSelector("a.cspbItm"))

Answer 2

发现问题，这是由于iFrame中存在元素造成的。

首先切换到iFrame时，现在能够找到元素。
