Validation Callback

Since version 1.4.14

Validation Callback are useful when you want to run extra piece of code but only after the Validation is over.

Oh but wait a minute...

• But why do we need that?
• Shouldn't the Validation be super fast anyway?

The answer is yes but no. The validation when it runs is indeed super fast but the problem is that Angular-Validation has a debounce of 1 sec by default. The debounce basically waits for the user inactivity before doing any kind of validation. So the validation-callback will help dealing with this problem.

Internally the validation-callback is connected to a promise, it basically resolves whenever the validation is finished.

####Directive

<!-- defining the remote function call by using `custom:` -->
<input type="text" class="form-control"
            name="input1"
            ng-model="vm.model.input1"
            validation="required"
            validation-callback="myCallbackFunction()" />

<!-- or if you use the Controller As alias -->
<input type="text" class="form-control"
            name="input1"
            ng-model="vm.model.input1"
            validation="required"
            validation-callback="vm.myCallbackFunction()" />
