Using below jQuery methods, you can make ajax calls:

► load() : Load a piece of html into a container DOM

► $.getJSON(): Load JSON with GET method.

► $.getScript(): Load a JavaScript file.

► $.get(): Use to make a GET call and play extensively with the response.

► $.post(): Use to make a POST call and don't want to load the response to some container DOM.

► $.ajax(): Use this to do something on XHR failures, or to specify ajax options (e.g. cache: true) on the fly.
