/**
 * 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
 *
 *  method:   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)
 *
 *  before:   @deprecated use 'beforeSubmit'
 *  beforeSubmit:  Callback method to be invoked before the form is submitted.
 *            default value: null
 *
 *  after:    @deprecated use 'success'
 *  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
 *
 *
 * 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 'after'
 *                   callback method, if specified, will be passed the responseXML value
 *      'json':   if dataType == 'json' the server response will be evaluted and passed to
 *                   the 'after' 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.  If your
 * form must be submitted with name/value pairs in semantic order then pass true for this arg,
 * otherwise pass false (or nothing) to avoid the overhead for this logic (which can be
 * significant for very large forms).
 *
 * 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 = {

/**
 * 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.

/**
 * formToArray() gathers form element data into an array of objects that can
 * be passed to any of the following ajax functions: $.get, $.post, or load.
 * Each object in the array has both a 'name' and 'value' property.  An example of
 * an array for a simple login form might be:
 *
 * [ { name: 'username', value: 'jresig' }, { name: 'password', value: 'secret' } ]
 *
 * It is this array that is passed to pre-submit callback functions provided to the
 * ajaxSubmit() and ajaxForm() methods.
 *
 * The semantic argument can be used to force form serialization in semantic order.
 * If your form must be submitted with name/value pairs in semantic order then pass
 * true for this arg, otherwise pass false (or nothing) to avoid the overhead for
 * this logic (which can be significant for very large forms).
