如何使用Selenium和Python单击选项卡元素

Question

我知道已经有类似的问题，但是这些答案都没有帮助我。

我在以下方面遇到一些问题。我有以下标签：

该特定部分的HTML代码如下：

<td class="Tab1TblSelTd"><div class="Tab1SelTxtNew" title="Current Selection: Common Tasks">Common Tasks</div></td>
<td><a href="../task/Home?Home.tabCommon.TabHref=1&amp;jato.pageSession=AKztAAVzcgARamF2YS51dGlsLkhhc2hNYXAFB9rBwxZg0QMAAkYACmxvYWRGYWN0b3JJAAl0aHJlc2hvbGR4cD9AAAAAAAAMdwgAAAAQAAAABHQADGN1cnJlbnRSZWFsbXQAAS90ABRDQ1RhYnMuU2VsZWN0ZWRUYWJJZHQAATB0ABVvcGVuc3NvLlNlbGVjdGVkVGFiSWR0AAEwdAASQ3VycmVudFByb2ZpbGVWaWV3dAABL3g$" name="Home.tabCommon.TabHref" class="Tab1Lnk" title="Click to configure access control" onmouseover="window.status='Click to configure access control'; return true" onmouseout="window.status=''; return true" onblur="window.status=''; return true" onfocus="window.status='Click to configure access control'; return true">Access Control</a></td>
<td><a href="../task/Home?Home.tabCommon.TabHref=2&amp;jato.pageSession=AKztAAVzcgARamF2YS51dGlsLkhhc2hNYXAFB9rBwxZg0QMAAkYACmxvYWRGYWN0b3JJAAl0aHJlc2hvbGR4cD9AAAAAAAAMdwgAAAAQAAAABHQADGN1cnJlbnRSZWFsbXQAAS90ABRDQ1RhYnMuU2VsZWN0ZWRUYWJJZHQAATB0ABVvcGVuc3NvLlNlbGVjdGVkVGFiSWR0AAEwdAASQ3VycmVudFByb2ZpbGVWaWV3dAABL3g$" name="Home.tabCommon.TabHref" class="Tab1Lnk" title="Click to go to Federation" onmouseover="window.status='Click to go to Federation'; return true" onmouseout="window.status=''; return true" onblur="window.status=''; return true" onfocus="window.status='Click to go to Federation'; return true">Federation</a></td>
<td><a href="../task/Home?Home.tabCommon.TabHref=4&amp;jato.pageSession=AKztAAVzcgARamF2YS51dGlsLkhhc2hNYXAFB9rBwxZg0QMAAkYACmxvYWRGYWN0b3JJAAl0aHJlc2hvbGR4cD9AAAAAAAAMdwgAAAAQAAAABHQADGN1cnJlbnRSZWFsbXQAAS90ABRDQ1RhYnMuU2VsZWN0ZWRUYWJJZHQAATB0ABVvcGVuc3NvLlNlbGVjdGVkVGFiSWR0AAEwdAASQ3VycmVudFByb2ZpbGVWaWV3dAABL3g$" name="Home.tabCommon.TabHref" class="Tab1Lnk" title="Click to go to Configuration" onmouseover="window.status='Click to go to Configuration'; return true" onmouseout="window.status=''; return true" onblur="window.status=''; return true" onfocus="window.status='Click to go to Configuration'; return true">Configuration</a></td>

</tr>
</table>

我想单击访问控制。

这就是我要使用的：

wait.until(ec.presence_of_element_located((By.LINK_TEXT, 'Access Control'))).click()

显然可以找到这些元素，但是没有单击它。没有任何例外或消息，只是不单击它即可。

我以前在其他链接上使用了这种方法，但没有问题，所以我很确定自己在这里一定做错了。

你能帮忙吗？

谢谢！

Answer 1

根据 HTML ，您共享了对文本为访问控制的元素调用click()而不是使用方法presence_of_element_located()需要使用方法 element_to_be_clickable() ，您可以使用以下任一解决方案：

• 使用LINK_TEXT：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.LINK_TEXT, "Access Control"))).click()
  

• 使用CSS_SELECTOR：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.Tab1Lnk[title$='access control']"))).click()
  

• 使用XPATH：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='Tab1Lnk'][contains(@title,'access control')]"))).click()
  

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

Answer 2

尝试单击父td元素而不是xpath：

//td[./a[.='Access Control']]
