[SOLVED] How to handle pagination if only javascript can be loaded in BeautifulSoup Python


This Content is from Stack Overflow. Question asked by theycallmepix

It’s been hours since I am stuck here.
The entire code has been uploaded below.
The url: “https://www.bostonpublicschools.org/Page/628” is of only 1 page. However, it has 5 pages within itself that can be loaded by clicking on the page-icon at the bottom. This loads a javascript file that cannot be opened on a new tab (trying to open results in page getting blocked). Also, it loads on the same page.

I’ve so far looked at more than 100 solutions and tried many of them and none of them worked for me. Also, I do believe that this can be solved by using selenium as it can interact with the UI.

Is there any way I can get the job done within BeautifulSoup?
