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

-/**\r
- * ajaxForm() provides a mechanism for fully automating form submission.\r
- *\r
- * The advantages of using this method instead of ajaxSubmit() are:\r
- *\r
- * 1: This method will include coordinates for <input type="image" /> elements (if the element\r
- * is used to submit the form).\r
- * 2. This method will include the submit element's name/value data (for the element that was\r
- * used to submit the form).\r
- * 3. This method binds the submit() method to the form for you.\r
- *\r
- * Note that for accurate x/y coordinates of image submit elements in all browsers\r
- * you need to also use the "dimensions" plugin (this method will auto-detect its presence).\r
- *\r
- * The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely\r
- * passes the options argument along after properly binding events for submit elements and\r
- * the form itself. See ajaxSubmit for a full description of the options argument.\r
- *\r
- *\r
- * @example\r
- * var options = {\r
- * target: '#myTargetDiv'\r
- * };\r
- * $('#myForm').ajaxSForm(options);\r
- * @desc Bind form's submit event so that 'myTargetDiv' is updated with the server response\r
- * when the form is submitted.\r
- *\r
- *\r
- * @example\r
- * var options = {\r
- * success: function(responseText) {\r
- * alert(responseText);\r
- * }\r
- * };\r
- * $('#myForm').ajaxSubmit(options);\r
- * @desc Bind form's submit event so that server response is alerted after the form is submitted.\r
- *\r
- *\r
- * @example\r
- * var options = {\r
- * beforeSubmit: function(formArray, jqForm) {\r
- * if (formArray.length == 0) {\r
- * alert('Please enter data.');\r
- * return false;\r
- * }\r
- * }\r
- * };\r
- * $('#myForm').ajaxSubmit(options);\r
- * @desc Bind form's submit event so that pre-submit callback is invoked before the form\r
- * is submitted.\r

+ Usage Note:
+ -----------
+ Do not use both ajaxSubmit and ajaxForm on the same form. These
+ functions are intended to be exclusive. Use ajaxSubmit if you want
+ to bind your own submit handler to the form. For example,
+
+ $(document).ready(function() {
+ $('#myForm').bind('submit', function(e) {
+ e.preventDefault(); // <-- important
+ $(this).ajaxSubmit({
+ target: '#output'
+ });
+ });
+ });
+
+ Use ajaxForm when you want the plugin to manage all the event binding
+ for you. For example,
+
+ $(document).ready(function() {
+ $('#myForm').ajaxForm({
+ target: '#output'
+ });
+ });
+
+ When using ajaxForm, the ajaxSubmit function will be invoked for you
+ at the appropriate time.
