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.

/**
* ajaxForm() provides a mechanism for fully automating form submission.

*
* 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.
