2. $.ajaxSetup() : This function is used to define and set the options for various ajax calls.

$.ajaxSetup({
"type":"POST",
"url":"ajax.php",
"success":function(data)
{
$("#bar")
.css("background","yellow")
.html(data);
}
});
3. Shorthand ajax methods : They comprise of simply the wrapper function that call $.ajax() with certain parameters already set.
4. $.getJSON() : This is a special type of shorthand function which is used to accept the url to which the requests are sent. Also optional data and optional callback functions are possible in such functions.
