无法在 Selenium 中找到元素？

Question

I am getting the following error in Pycharm:

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: {"method":"css selector","selector":".fbc-imageselect-checkbox-9"}

It is producing this error on this line:

driver.find_element_by_css_selector('.fbc-imageselect-checkbox-9').click()

Where driver is the firefox, using selenium. I am attempting to click on the item that is linked to the CSS selector fbc-imageselect-checkbox-9 on the website: http://topg.org/Minecraft/in-414300

Please note, changing your user agent to mobile will produce the grid of images.

What am I doing wrong? Shouldn't this CSS selector work?

Answer 1

Should it work? Probably not. When I view the page there is no such element (UA "Mozilla/5.0 (X11; Linux x86_64; rv:40.0) Gecko/20100101 Firefox/40.0"):

jQuery.find(".fbc-imageselect-checkbox-9")
Array [  ]

You probably need to rewrite your query a little more robustly.
