Passing data from javascript into Flask

Question

I know how to pass data with a jinja template from python into javascript, but I want to pass a javascript variable into python. I'd like to do it without reloading the page. Is that possible?

Answer 1

Yes, like monkut said--I believe you want to use JSON and Javascript/jQuery.

This will let allow communication from client to server and back again.

The most applicable example I found was in the Flask snippets/patterns: http://flask.pocoo.org/docs/patterns/jquery/
