Django

Hello everyone, tell me please, the essence of the problem is as follows. I do not understand what technologies and how to apply?
i am writing a django project and i need to make a dynamic select + i need to pass 2 values ​​from the select to the django view. for this I need to track the selection in the select using js, how to make json and pass it to the django view.
How it's done ? Are the scripts written in pure JS or jQuery?
How after the js function has completed pass with ajax to django ?
what a complex relationship. Or should I study react instead of jquery and JS?

Answer 1

All the suggested options are working, because, obviously, jQ and react are written in pure JS.
