Doubt: the parameters in the link are generated by js. How do you find the generated parameters in js?

RT.
Link (list page) for example: expIds= to & callback=__jp8 , it seems that the parameters are generated by the js file, because these parameters are the details page URL of the list page, that is, when the list page link is loaded, the details page link of the list page is loaded.
