如何使用带有 aria-label 的 selenium 单击 python 中的按钮

Question

I am trying to find and click a close button on an iframe.

 <modal-container class="modal fade show" role="dialog" tabindex="-1" style="display: block;" aria-modal="true"><div role="document" class="modal-dialog modal-xl"><div class="modal-content"><div _ngcontent-gtk-c9="" class="modal-header card-header modal-header-news-expanded"><h4 _ngcontent-gtk-c9="" align="center" class="modal-title col-11 text-center">Article Title PDF </h4><button _ngcontent-gtk-c9="" aria-label="Close" class="close close_white_color" type="button"><span _ngcontent-gtk-c9="" aria-hidden="true">×</span></button></div><br _ngcontent-gtk-c9=""><div _ngcontent-gtk-c9="" class="container-fluid"><.----><div _ngcontent-gtk-c9="" class="row"><!----><div _ngcontent-gtk-c9="" class="col-md-12 ng-star-inserted"><!----><iframe _ngcontent-gtk-c9="" id="pdf_iframe_outside_modal" src="link.com" class="ng-star-inserted" cd_frame_id_="337af673cf64fd1888fcd2afe645984c"></iframe><!----></div></div><!----></div></div></div></modal-container>

I have tried the following methods:

Try1:

close = driver.find_element_by_xpath("//button[@aria-label=Close']").click()

Try2:

close = driver.find_element_by_xpath("//button[@class='close close_white_color']").click()

Try3:

close = driver.find_element_by_xpath("//button[contains(@class,\"close close_white_color\")]").click()

Which gives following error

Error1:

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//button[@aria-label='Close']"}

Error2:

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//button[@class='close close_white_color']"}

Error3:

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//button[contains(@class,"close close_white_color")]"}

I am able to interact with the iframe but unable to locate this button. Any suggestions would be appreciated

A couple of things here:

• The element isn't within the iframe
• click() doesn't returns anything.

Solution

The desired element is within a Modal Dialog Box , to click on the clickable element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies :

• Using CSS_SELECTOR :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.close.close_white_color[aria-label='Close'] > span"))).click()

• Using XPATH :

   //button[@class='close close_white_color' and @aria-label='Close']/span

• 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
