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

<script>

Debug View:

<pre>form={{form}}
|

master={{master}}</pre>

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.
