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

问题描述：

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.我正在尝试点击关闭"按钮.我已经尝试了以下所有三个代码块，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?

I have a page with source code like the code below. In it after I take an action an "Undo" and a "Close" button appear. I’m trying to click the "Close" button. I’ve tried all three of the chunks of code below, none are working. Can someone please point out what I’m doing wrong, or suggest something else to try?

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:

答

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

The element with text as Close is a dynamic element so to locate the element you have to induce WebDriverWait for the element to be clickable and you can use either of the following solutions:

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:

Note : You have to add the following imports :

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