DOM Traversal Methods - MarkMail

AJAX Methods
A response that the page is not modified is still treated as a success. In this case the
callback will still be executed, but no data will be available. The callback should trap
for this to avoid discarding previously-fetched data.
.load()
Loads data from the server and places the returned HTML into the matched element.
.load(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 jQuery object, for chaining purposes.
Description
This method is the simplest way to fetch data from the server. It is roughly
equivalent to $.get(url, data, success) except that it is a method rather than a
global function and it has an implicit callback function. When a successful response
is detected, .load() sets the HTML contents of the matched element to the returned
data. This means that most uses of the method can be quite simple:
$('.result').load('ajax/test.html');
The provided callback, if any, is executed after this post-processing has
been performed:
$('.result').load('ajax/test.html', function() {
$(this).log('Load was performed.');
});
The POST method is used if data is provided; otherwise, GET is assumed.
The event handling suite also has a method named .load(). Which one
is fired depends on the set of arguments passed.
