Question

我正在尝试通过单击右上角的图片来结束脚本，这会导致退出菜单位于退出按钮的位置。我可以让Selenium识别图片，然后单击图片以显示下拉菜单，但我无法单击最后一个按钮。

这是网站上我要单击的“注销”按钮的代码：

<a id="ctl00_ctl00_mainContent_MainHeader_HeaderSection_lnkLogout" href="javascript:__doPostBack('ctl00$ctl00$mainContent$MainHeader$HeaderSection$lnkLogout','')"><i class="fa fa-power-off  fa-fw"></i>
                                <span>Log Out</span> </a>

这是整个下拉列表的全部代码。看来这是我第一次没有意识到的清单，但我记得读过您可以按数字选择清单吗？

<div class="dropdown header-container user-actions-container open">

                        <a id="ctl00_ctl00_mainContent_MainHeader_HeaderSection_hypPicture" class="employee-picture" role="button" data-toggle="dropdown" aria-expanded="true"><span id="ctl00_ctl00_mainContent_MainHeader_HeaderSection_imgPicture" alternatetext="Employee Picture" imagealign="Top"><img class="img-rounded" src="https://share.striven.com//pimg/BA4FE360/Employee/thumb-b8598be5-5cd3-48c3-86ab-79fc9985b95e-07252018.jpg"></span></a>

                        </ul>
                </div>

我试图模仿这段代码，有人在这里帮我完成了几乎相同的事情：

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.hub-content-item[id*='SearchExplorer'][actiontype='Secondary']>span")))

但它不会为我识别它。

您非常接近。 <span>标签不是立即子，因此您需要将 > 替换为 space 字符，然后使用以下Locator Strategies之一：

使用CSS_SELECTOR：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a[id$='mainContent_MainHeader_HeaderSection_lnkLogout'] span"))).click()

使用XPATH：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[contains(@id, 'mainContent_MainHeader_HeaderSection_lnkLogout')]//span[text()='Log Out']"))).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

在Python中单击带有Selenium的下拉菜单
