ElementNotVisibleException：消息：尝试通过Selenium和Python单击按钮时，元素不可交互错误

Question

我有一个包含源代码的页面，如下面的代码。在执行操作后，在其中显示“撤消”和“关闭”按钮。我试图单击“关闭”按钮。我已经尝试了下面的所有三个代码块，但都无法正常工作。有人可以指出我做错了什么，还是建议其他尝试？

html来源：

<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：

与文本的元素 关闭 是一个动态的元素，以便找到你要引起元素 WebDriverWait 的 元素是可点击 ，你既可以使用以下方法解决：

• 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
