What is the difference between XMLHttpRequest, jQuery.ajax, jQuery.post, jQuery.get

Question

How can I find out which method is best for a situation? Can anybody provide some examples to know the difference in terms of functionality and performance?

Answer 1

Each one of them uses XMLHttpRequest. This is what the browser uses to make the request. jQuery is just a JavaScript library and the $.ajax method is used to make a XMLHttpRequest.

$.post and $.get are just shorthand versions of $.ajax. They do pretty much the same thing but makes it quicker to write an AJAX request - $.post makes a HTTP POST request and $.get makes a HTTP GET request.
