Site parsing after js loading?

Question

Python

There is a site that needs to be parsed ( https://catalog.onliner.by/mobile ). However, it loads the data via js. I'm using the requests python library, however it parses the page before requests (requests.get(url)). How to parse the page completely or make the parser stay on the page?

import requests

f = open ('ind.txt', 'w')
url ='https://catalog.onliner.by/mobile?mfr%5B0%5D=xiaomi'
r = requests.get(url)
f.write(r.text)
print(r.text)
f.close()
