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 |XMLHttpRequest|_, |fetch|_, and
|
||
|
|
|jQuery.ajax|_. See the `Flask docs`_ about jQuery and Ajax.
