DOM Traversal Methods

AJAX Methods
Shorthand Methods
These methods perform the more common types of AJAX requests in less code.
$.get()
Loads data from the server using a GET HTTP request.
$.get(url[, data][, success])
Parameters
• url: A string containing the URL to which the request is sent
•
•
data: (optional): A map of data that is sent with the request
success: (optional): A function that is executed if the request succeeds
Return Value
The XMLHttpRequest object that was created.
Description
This is a shorthand AJAX function, which is equivalent to:
$.ajax({
url: url,
data: data,
success: success
});
The callback is passed the returned data, which will be an XML root element or a text
string depending on the MIME type of the response.
Most implementations will specify a success handler:
$.get('ajax/test.html', function(data) {
$('.result').html(data);
$().log('Load was performed.');
});
This example fetches the requested HTML snippet and inserts it on the page.
