/**\r
- * Initial frontend function to submit form variables. This function\r
- * is for registering coordinates, in the case of an image being used\r
- * as the submit element, and sets up an event to listen and wait for\r
- * a form submit click. It then calls any following chained functions\r
- * to actually gather the variables and submit them.\r
+ * A method for submitting an HTML form using AJAX, as opposed to the\r
+ * standard page-load way.\r
*\r
- * Usage examples, when used with getForm().putForm():\r
+ * This method attempts to mimic the functionality of the original form\r
+ * as best as possible (duplicating the method, action, and exact contents\r
+ * of the form).\r
+ *\r
+ * There are three different resulting operations that can occur, after\r
+ * your form has been submitted.\r
+ *\r
+ * 1. The form is submitted and a callback is fired, letting you know\r
+ * when it's done:\r
+ * $("form").ajaxSubmit(function(){\r
+ * alert("all done!");\r
+ * });\r
+ *\r
+ * 2. The form is submitted and the resulting HTML contents are injected\r
+ * into the page, at your specified location.\r
+ * $("form").ajaxSubmit("#destination");\r
+ *\r
+ * 3. The form is submitted and the results returned from the server are\r
+ * automatically executed (useful for having the server return more\r
+ * Javascript commands to execute).\r
+ * $("form").ajaxSubmit();\r
+ *\r
+ * Additionally, an optional pre-submit callback can be provided. If it,\r
+ * when called with the contents of the form, returns false, the form will\r
+ * not be submitted.\r
+ *\r
+ * Finally, both the URL and method of the form submission can be\r
+ * overidden using the 'url' and 'mth' arguments.\r
+ *\r
+ * @param target arg for the target id element to render\r
+ * @param post_cb callback after any results are returned\r
+ * @param pre_cb callback function before submission\r
+ * @param url form action override\r
+ * @param mth form method override\r
+ * @return "this" object\r
+ * @see ajaxForm(), serialize(), load(), $.xml()\r

+/**\r
+ * This function can be used to turn any HTML form into a form\r
+ * that submits using AJAX only.\r
+ *\r
+ * The purpose of using this method, instead of the ajaxSubmit()\r
+ * and submit() methods, is to make absolutely sure that the\r
+ * coordinates of <input type="image"/> elements are transmitted\r
+ * correctly OR figuring out exactly which <input type="submit"/>\r
+ * element was clicked to submit the form.\r
+ *\r
+ * If neither of the above points are important to you, then you'll\r
+ * probably just want to stick with the simpler ajaxSubmit() function.\r
+ *\r
+ * Usage examples, similar to ajaxSubmit():\r
*\r
* 1. Just eval the results returned from the backend.\r
- * $('#form-id').form();\r
+ * $('#form-id').ajaxForm();\r
*\r
* 2. Render backend results directly to target ID (expects (x)HTML).\r
- * $('#form-id').form('#target-id');\r
+ * $('#form-id').ajaxForm('#target-id');\r
*\r
* 3. Submit to backend URL (form action) then call this function.\r
- * $('#form-id').form(post_callback);\r
+ * $('#form-id').ajaxForm(post_callback);\r
*\r
* 4. Load target ID with backend results then call a function.\r
- * $('#form-id').form('#target-id', null, post_callback);\r
+ * $('#form-id').ajaxForm('#target-id', post_callback);\r
*\r
* 5. Call a browser function (for validation) and then (optionally)\r
* load server results to target ID.\r
- * $('#form-id').form('#target-id', pre_callback);\r
+ * $('#form-id').ajaxForm('#target-id', null, pre_callback);\r
*\r
* 6. Call validation function first then load server results to\r
* target ID and then also call a browser function.\r
- * $('#form-id').form('#target-id', pre_callback, post_callback);\r
+ * $('#form-id').ajaxForm('#target-id', post_callback, pre_callback);\r
