[FIXED] Selenium: Get the URL that Javascript codes redircted to without changing current page

Issue

I want to get the URL I am re-directed to when I click one button on the website, and still stay on the same page instead of being redirected. The button is not a simple hyperlink and will trigger a complex Javascript function.

click() does not work for me

I refer to Selenium get URL of "a" Tag without href attribute and Selenium: Getting ultimate href/link without clicking on it when it's a javascript call, which shows that the button has to be clicked to get the URL. Of course, I can click() the button and use 'driver.current_url', but in this way I am redirected to a new URL. I do not want the redirection since I have more things to do on the current page and want to stay on the same page. I can not use CTRL + click to open the new page in a new tab, either.

My idea

I read about how to find the source Javascript code (How to find what code is run by a button or element in Chrome using Developer Tools), but I found the codes too complex for me. Should I find the codes that produce the URL?

I wonder can I just "fork" the current page? Or something like simulating/executing the Javascript code in a separate sandbox? I am using python.

Solution

I finally found a solution. The idea is to modify the javascript codes.

Step 1: locate the javascript codes that cause the redirection.

Refer to this answer. Note that for me I also add Event Listener Breakpoints for the load event.

Step 2: modify the javascript codes and delete redirection

Just find the line where the new URL has been computed and is being directed to. Store the url in a global javascript variable target_url.

Step 3: Use an extension to do the modification automatically in Selenium

See my answer. In a word, use the extension Resource Override.

Step 4: Selenium side, get the variable url

my_target_url = driver.execute_script("return target_url;")
