/**
 * 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
 *
 *
 * @name ajaxSubmit
 * @type jQuery
 * @param options  object literal containing options which control the form submission process
 * @cat Plugins/Form
 * @return jQuery

/**
 * 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);
