* name: $.fn.formValues

* example: $('#frmLogin').formValues('sButton')
|
||||
* docs: Gets form values and creates a key=>value array of the found values.
|
||||
* Optionally adds the button which is clicked if you provide it.
|
||||
* Only does this for ENABLED elements in the order of the form.
|
||||
* Initial frontend function to submit form variables. This function
|
||||
* is for registering coordinates, in the case of an image being used
|
||||
* as the submit element, and sets up an event to listen and wait for
|
||||
* a form submit click. It then calls any following chained functions
|
||||
* to actually gather the variables and submit them.
|
||||
*
|
||||
* Usage examples, when used with getForm().putForm():
|
||||
*
|
||||
* 1. Just eval the results returned from the backend.
|
||||
* $('#form-id').form();
|
||||
*
|
||||
* 2. Render backend results directly to target ID (expects (x)HTML).
|
||||
* $('#form-id').form('#target-id');
|
||||
*
|
||||
* 3. Submit to backend URL (form action) then call this function.
|
||||
* $('#form-id').form(post_callback);
|
||||
*
|
||||
* 4. Load target ID with backend results then call a function.
|
||||
* $('#form-id').form('#target-id', null, post_callback);
|
||||
*
|
||||
* 5. Call a browser function (for validation) and then (optionally)
|
||||
* load server results to target ID.
|
||||
* $('#form-id').form('#target-id', pre_callback);
|
||||
*
|
||||
* 6. Call validation function first then load server results to
|
||||
* target ID and then also call a browser function.
|
||||
* $('#form-id').form('#target-id', pre_callback, post_callback);
