Because of changes in jQuery, we need to use element().prop() instead of element().attr() to retrieve className and other element properties.
Additionally all attribute selectors (e.g. input[name=value]) must have value quoted if it contains dots (".").

@description

Here we extend the basic form example to include common features such as reverting, dirty state
|
|
detection, and preventing invalid form submission.

#Things to notice
|
|
|
|
* Cancel & save buttons are only enabled if the form is dirty — there is something to cancel or
|
|
save.
|
|
* Save button is only enabled if there are no validation errors on the form.
|
|
* Cancel reverts the form changes back to original state.
|
|
* Save updates the internal model of the form.
|
|
* Debug view shows the two models. One presented to the user form and the other being the pristine
|
|
copy master.
