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(); // = 200 && xhr.status < 300 || xhr.status === 304) ? 'success' : 'error';
}
// ordering of these callbacks/triggers is odd, but that's how $.ajax does it
if (status === 'success') {
if (s.success) {
s.success.call(s.context, data, 'success', xhr);
}
deferred.resolve(xhr.responseText, 'success', xhr);
if (g) {
$.event.trigger("ajaxSuccess", );
}
}
else if (status) {
if (errMsg === undefined) {
errMsg = xhr.statusText;
}
if (s.error) {
s.error.call(s.context, xhr, status, errMsg);
}
deferred.reject(xhr, 'error', errMsg);
if (g) {
$.event.trigger("ajaxError", );
}
}
if (g) {
$.event.trigger("ajaxComplete", );
}
if (g && ! --$.active) {
$.event.trigger("ajaxStop");
}
if (s.complete) {
s.complete.call(s.context, xhr, status);
}
callbackProcessed = true;
if (s.timeout) {
clearTimeout(timeoutHandle);
}
// clean up
setTimeout(function() {
if (!s.iframeTarget) {
$io.remove();
}
else { //adding else to clean up existing iframe response.
$io.attr('src', s.iframeSrc);
}
xhr.responseXML = null;
}, 100);
}
var toXml = $.parseXML || function(s, doc) { // use parseXML if available (jQuery 1.5+)
if (window.ActiveXObject) {
doc = new ActiveXObject('Microsoft.XMLDOM');
doc.async = 'false';
doc.loadXML(s);
}
else {
doc = (new DOMParser()).parseFromString(s, 'text/xml');
}
return (doc && doc.documentElement && doc.documentElement.nodeName != 'parsererror') ? doc : null;
};
var parseJSON = $.parseJSON || function(s) {
/*jslint evil:true */

/**
* ajaxForm() provides a mechanism for fully automating form submission.
*
* The advantages of using this method instead of ajaxSubmit() are:
*
* 1: This method will include coordinates forelements (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.
