Using Python and Selenium, receiving the error message "element is not attached to the page document"

I am facing an issue with a python function that is supposed to cycle through all options of a product:

submit_button = driver.find_element_by_id('quantityactionbox')

elementList = submit_button.find_elements_by_tag_name("option")

for x in elementList:
    x.click()

However, after clicking on 2 options, I encounter the following error message:

selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document

I would appreciate some insights on why this error occurs and any suggestions on how to successfully navigate through all elements?

Answer №1

To tackle various errors like these, a simple solution is to introduce a small delay:

import time

time.sleep(1)

Executing DOM manipulation post an event often requires some processing time, hence incorporating a slight delay does not significantly impact performance.

Answer №2

Here's where you can find both the explanation and the solution: Dealing With an Element That is Not Attached to the DOM:

When working with a tabbed interface on a website, it's common to have multiple DIVs prepared for each tab but only display one at a time. The others are usually stored in variables until needed. In such cases, it's possible that your code may still hold a reference to an element that is no longer attached to the document object model (DOM), specifically when its ancestor is "document.documentElement".

If WebDriver throws a stale element exception even though the element technically exists, it means that the reference has become outdated. To resolve this issue, you should discard the old reference and re-locate the element once it becomes attached to the DOM again.

Answer №3

One reason for my issue was due to the page being updated and the element no longer existing, causing my script to fail when attempting to access it. Although a similar element appeared on the refreshed page, it was not recognized as the same one and thus could not be accessed within the current document. To resolve this, I had to redefine the element after the page was reloaded.

Answer №4

What happened in my situation was that Chrome had been updated, but I was still using an older version of the 'chrome driver.exe'. It's important to always make sure you have the correct version for optimum performance.
