/**


 * 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.
