Selenium Automation使用Python和Selenium在ul中选择li菜单项

Question

因此，我遇到了一个总体问题，我试图自动登录、菜单项选择，然后预填充字段以初始化文件下载。我已经能够自动登录，非常感谢在另一篇文章中提供的答案。但是，我没有成功地尝试导航到特定的菜单项并选择该项以进入新页面。如果我直接进入该页面，我已注销，必须重新登录。这里有一个名为“自定义报告”的站点，这是我需要单击以转到另一个页面的位置。如果li对象有ID，这将使这变得容易得多，但是没有可以想象的ID。这是我试图自动生成的网页的源代码，请按照我存储在github中的链接进行操作

https://github.com/Richard-Barrett/ITDataServicesInfra/blob/master/Python/Collegeboard/TSI/tsi_pagesource

我正在尝试单击此元素

                  <li ng-show="core.acl['244']!='N'" ng-class="{active:isLocation('/customReports')}">
                     <a href="#/customReports" translate='reports.CustomReports.title'></a>
                  </li>

正如你所能想象的那样，我一直未能做到这一点。 这是我目前用来提取信息的代码。登录自动化工作

每次我尝试使用xpath时，它都不会给我任何东西，基本上说它不存在

Answer 1

所需的元素是Angular元素，因此要在元素上定位和click()，您需要为element_to_be_clickable()诱导WebDriverWait，并且可以使用以下任一Locator Strategies：

• 使用CSS_SELECTOR：

  WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "li>a[href$='customReports'][translate*='CustomReports']"))).click()
  

• 使用XPATH：

  WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//li/a[contains(@href,'customReports') and contains(@translate, 'CustomReports')]"))).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

请使用xpath和webdriver explicit wait尝试下面的代码

element = WebDriverWait(browser, 20).until(
EC.element_to_be_clickable((By.XPATH, "//a[contains(@href, '/customReports')]")))
element.click();

你需要在下面输入

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

或

不推荐，但在大多数情况下都是可行的解决方案（尝试使用Java脚本单击，但不要等待，因为等待失败）

element=browser.find_element(By.XPATH, "//a[contains(@href, '/customReports')]")
browser.execute_script("arguments[0].click();", element)

Answer 3

所以我最终找到了解决办法。解决方案是，我必须首先导航到报表，然后移动到自定义报表的子项。我用Link_文本代替

element = WebDriverWait(browser, 20).until(
        EC.element_to_be_clickable((By.LINK_TEXT, "Reports")))
element.click();

element = WebDriverWait(browser, 20).until(
                EC.element_to_be_clickable((By.LINK_TEXT, "Custom Reports")))
element.click();

我感谢你们这些@DebanjB和@Muzzamil的帮助，我怀疑如果没有他们的指导，我将无法找到如何做到这一点！非常感谢你们两位
