10,440 PointsHow to create Infinite scrolling in Flask app?
Hi! I want my webpage to load more data on scroll. The application is built in Flask. I am a bit lost; how to implement that and from where to start? Can anyone help please by recommending something or sharing a good source of explanation? I was unable to find something meaningful for Flask app so far. Cheers.

Treehouse Guest TeacherYou'd need a view that takes a starting place for fetching records. Let's say you do 10 records at a time. When you hit that view, and you say "start=10", that view gives you items 10-20 back as JSON or whatever you need. Then, when they scroll far enough, you ask for "start=20" and get back the next set of items.
As for the requesting and fetching, that would be done though JavaScript.

10,440 PointsThank you. Is AJAX anyhow required in your method or will it simply work if a JS function request for the view function every time a user hits the end?

Treehouse Guest TeacherIt will involve AJAX, yes, because you'll be receiving a new partial bit of data from the server asynchronously. It doesn't have to be XML, of course.
