Usage Note:
|
|
-----------
|
|
Do not use both ajaxSubmit and ajaxForm on the same form. These
|
|
functions are mutually exclusive. Use ajaxSubmit if you want
|
|
to bind your own submit handler to the form. For example,
|
|
|
|
$(document).ready(function() {
|
|
$('#myForm').on('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'
|
|
});
|
|
});
|
|
|
|
You can also use ajaxForm with delegation (requires jQuery v1.7+), so the
|
|
form does not have to exist when you invoke ajaxForm:
|
|
|
|
$('#myForm').ajaxForm({
|
|
delegation: true,
|
|
target: '#output'
|
|
});
|
|
|
|
When using ajaxForm, the ajaxSubmit function will be invoked for you
|
|
at the appropriate time.

|
|
* 1: This method will include coordinates for <input type="image" /> elements (if the element
|
|
* is used to submit the form).
|
|
* 2. This method will include the submit element's name/value data (for the element that was
|

* used to submit the form).
|
|
* 3. This method binds the submit() method to the form for you.
|
|
*
|
|
* The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely
|
|
* passes the options argument along after properly binding events for submit elements and
|
|
* the form itself.
