python-3.x - ElementNotVisibleException：消息：尝试通过 Selenium 和 Python 单击按钮时出现元素不可交互错误

问题描述

我有一个带有源代码的页面，如下面的代码。在我采取行动后，会出现“撤消”和“关闭”按钮。我正在尝试单击“关闭”按钮。我已经尝试了下面的所有三个代码块，都没有工作。有人可以指出我做错了什么，或者建议其他尝试吗？

html源码：

<div class="_3Aslx7L3GVI4XM7PUyYKza action-bar"><div class="container"><i class="success-icon fontello-ok-circle"></i><div class="success-message">Your stuff is going to <span>place</span> is on its way.</div><div class="gh69ID1m3_xtdTUQuwadU"><button class="c-button c-button--gray"> Undo</button></div><div class="gh69ID1m3_xtdTUQuwadU"><button class="c-button c-button--blue"> Close</button></div></div></div>

代码尝试：

#driver.find_element_by_id("gh69ID1m3_xtdTUQuwadU").click()
driver.find_element_by_css_selector('.c-button.c-button--blue').click()
#driver.find_element_by_link_text('Close').click()

错误：

解决方案

文本为Close的元素是动态元素，因此要定位元素，您必须诱导WebDriverWait以使元素可点击，您可以使用以下任一解决方案：

  • 使用CSS_SELECTOR：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.action-bar button.c-button.c-button--blue"))).click()

  • 使用XPATH：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[contains(@class, 'action-bar')]//button[@class='c-button c-button--blue' and normalize-space()='Close']"))).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
