JavaScript Ajax Example
=======================

Demonstrates how to post form data and process a JSON response using
JavaScript. This allows making requests without navigating away from the
page. Demonstrates using |fetch|_, |XMLHttpRequest|_,  and
|jQuery.ajax|_. See the `Flask docs`_ about JavaScript and Ajax.

.. |XMLHttpRequest| replace:: ``XMLHttpRequest``
.. _XMLHttpRequest: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest

.. |jQuery.ajax| replace:: ``jQuery.ajax``
.. _jQuery.ajax: https://api.jquery.com/jQuery.ajax/
