Using Shorthand AJAX Methods
There are several simple, one-use functions, available for performing common AJAX tasks. In a nutshell,
these shorthand methods are simply wrapper functions that call $.ajax() with some of the parameters
already set.
Using these methods will incur a slight performance penalty, since you’re essentially calling a
method that sets up parameters and calls $.ajax() within itself. However, the convenience of using
shorthand methods really speeds up development in many scripts.
$.get() and $.post()
For standard GET and POST requests, the $.get() and $.post() functions are easy to use. Both take four
arguments: the URL to which the request is to be sent, optional data to be sent to the remote script, an
optional callback to be executed if the request is successful, and an optional dataType setting.
To load the result of ajax.php using GET with no data sent, use the following:
$.get("ajax.php", function(data){
$("#bar")
.css("background","yellow")
.html(data);
});
