|  | 	Usage Note: | ||
|  | 	----------- | ||
|  | 	Do not use both ajaxSubmit and ajaxForm on the same form.  These | ||
|  | 	functions are intended to be exclusive.  Use ajaxSubmit if you want | ||
|  | 	to bind your own submit handler to the form.  For example, | ||
|  | 
 | ||
|  | 	$(document).ready(function() { | ||
|  | 		$('#myForm').bind('submit', function(e) { | ||
|  | 			e.preventDefault(); // <-- important
 | ||
|  | 			$(this).ajaxSubmit({ | ||
|  | 				target: '#output' | ||
|  | 			}); | ||
|  | 		}); | ||
|  | 	}); | ||
|  | 
 | ||
|  | 	Use ajaxForm when you want the plugin to manage all the event binding | ||
|  | 	for you.  For example, | ||
|  | 
 | ||
|  | 	$(document).ready(function() { | ||
|  | 		$('#myForm').ajaxForm({ | ||
|  | 			target: '#output' | ||
|  | 		}); | ||
|  | 	}); | ||
|  | 
 | ||
|  | 	When using ajaxForm, the ajaxSubmit function will be invoked for you | ||
|  | 	at the appropriate time. | ||
