Flask_AJAX

Basic example of a Flask application with AJAX

This is a basic example to understand how you can use Flask with AJAX with the framework Jquery. The example is divided in 6 small steps in order to understand how data are sent from the front-end to the back-end and from the back-end to the front-end.

Technologies used :

  • Python with Flask
  • HTML with Jinja2
  • Javascript with Jquery
  • Wikipedia API

Steps of the example :

  • STEP 1 (run.py) The user opens the home page
  • STEP 2 (main.html) The user fills the input box with a word
  • STEP 3 (main.html) An AJAX request is sent to the url /test_ajax/
  • STEP 4 (run.py) Data are collected from the request and sent to an API
  • STEP 5 (run.py) API Data are sent back to the template
  • STEP 6 (main.html) div#reponse is updated with API data
