-/**
- * ajaxSubmit() provides a mechanism for submitting an HTML form using AJAX.
- *
- * ajaxSubmit accepts a single argument which can be either a success callback function
- * or an options Object. If a function is provided it will be invoked upon successful
- * completion of the submit and will be passed the response from the server.
- * If an options Object is provided, the following attributes are supported:
- *
- * target: Identifies the element(s) in the page to be updated with the server response.
- * This value may be specified as a jQuery selection string, a jQuery object,
- * or a DOM element.
- * default value: null
- *
- * url: URL to which the form data will be submitted.
- * default value: value of form's 'action' attribute
- *
- * type: The method in which the form data should be submitted, 'GET' or 'POST'.
- * default value: value of form's 'method' attribute (or 'GET' if none found)
- *
- * data: Additional data to add to the request, specified as key/value pairs (see $.ajax).
- *
- * beforeSubmit: Callback method to be invoked before the form is submitted.
- * default value: null
- *
- * success: Callback method to be invoked after the form has been successfully submitted
- * and the response has been returned from the server
- * default value: null
- *
- * dataType: Expected dataType of the response. One of: null, 'xml', 'script', or 'json'
- * default value: null
- *
- * semantic: Boolean flag indicating whether data must be submitted in semantic order (slower).
- * default value: false
- *
- * resetForm: Boolean flag indicating whether the form should be reset if the submit is successful
- *
- * clearForm: Boolean flag indicating whether the form should be cleared if the submit is successful
- *
- *
- * The 'beforeSubmit' callback can be provided as a hook for running pre-submit logic or for
- * validating the form data. If the 'beforeSubmit' callback returns false then the form will
- * not be submitted. The 'beforeSubmit' callback is invoked with three arguments: the form data
- * in array format, the jQuery object, and the options object passed into ajaxSubmit.
- * The form data array takes the following form:
- *
- * [ { name: 'username', value: 'jresig' }, { name: 'password', value: 'secret' } ]
- *
- * If a 'success' callback method is provided it is invoked after the response has been returned
- * from the server. It is passed the responseText or responseXML value (depending on dataType).
- * See jQuery.ajax for further details.
- *
- *
- * The dataType option provides a means for specifying how the server response should be handled.
- * This maps directly to the jQuery.httpData method. The following values are supported:
- *
- * 'xml': if dataType == 'xml' the server response is treated as XML and the 'success'
- * callback method, if specified, will be passed the responseXML value
- * 'json': if dataType == 'json' the server response will be evaluted and passed to
- * the 'success' callback, if specified
- * 'script': if dataType == 'script' the server response is evaluated in the global context
- *
- *
- * Note that it does not make sense to use both the 'target' and 'dataType' options. If both
- * are provided the target will be ignored.
- *
- * The semantic argument can be used to force form serialization in semantic order.
- * This is normally true anyway, unless the form contains input elements of type='image'.
- * If your form must be submitted with name/value pairs in semantic order and your form
- * contains an input of type='image" then pass true for this arg, otherwise pass false
- * (or nothing) to avoid the overhead for this logic.
- *
- *
- * When used on its own, ajaxSubmit() is typically bound to a form's submit event like this:
- *
- * $("#form-id").submit(function() {
- * $(this).ajaxSubmit(options);
- * return false; // cancel conventional submit
- * });
- *
- * When using ajaxForm(), however, this is done for you.
- *
- * @example
- * $('#myForm').ajaxSubmit(function(data) {
- * alert('Form submit succeeded! Server returned: ' + data);
- * });
- * @desc Submit form and alert server response
- *
- *
- * @example
- * var options = {
- * target: '#myTargetDiv'
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc Submit form and update page element with server response
- *
- *
- * @example
- * var options = {
- * success: function(responseText) {
- * alert(responseText);
- * }
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc Submit form and alert the server response
- *
- *
- * @example
- * var options = {
- * beforeSubmit: function(formArray, jqForm) {
- * if (formArray.length == 0) {
- * alert('Please enter data.');
- * return false;
- * }
- * }
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc Pre-submit validation which aborts the submit operation if form data is empty
- *
- *
- * @example
- * var options = {
- * url: myJsonUrl.php,
- * dataType: 'json',
- * success: function(data) {
- * // 'data' is an object representing the the evaluated json data
- * }
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc json data returned and evaluated
- *
- *
- * @example
- * var options = {
- * url: myXmlUrl.php,
- * dataType: 'xml',
- * success: function(responseXML) {
- * // responseXML is XML document object
- * var data = $('myElement', responseXML).text();
- * }
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc XML data returned from server
- *
- *
- * @example
- * var options = {
- * resetForm: true
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc submit form and reset it if successful
- *
- * @example
- * $('#myForm).submit(function() {
- * $(this).ajaxSubmit();
- * return false;
- * });
- * @desc Bind form's submit event to use ajaxSubmit

-/**
- * 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 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.
- *
- * Note that for accurate x/y coordinates of image submit elements in all browsers
- * you need to also use the "dimensions" plugin (this method will auto-detect its presence).
- *
- * 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. See ajaxSubmit for a full description of the options argument.
- *
- *
- * @example
- * var options = {
- * target: '#myTargetDiv'
- * };
- * $('#myForm').ajaxSForm(options);
- * @desc Bind form's submit event so that 'myTargetDiv' is updated with the server response
- * when the form is submitted.
- *
- *
- * @example
- * var options = {
- * success: function(responseText) {
- * alert(responseText);
- * }
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc Bind form's submit event so that server response is alerted after the form is submitted.
- *
- *
- * @example
- * var options = {
- * beforeSubmit: function(formArray, jqForm) {
- * if (formArray.length == 0) {
- * alert('Please enter data.');
- * return false;
- * }
- * }
- * };
- * $('#myForm').ajaxSubmit(options);
- * @desc Bind form's submit event so that pre-submit callback is invoked before the form
- * is submitted.

- * @param options object literal containing options which control the form submission process
