ng-valid v1.0.0

ngValid

An AngularJS directive to trigger a method when an input is valid (or invalid).

The problem

This inside a controller:

if (form.inputName.$valid) {
    doSomething()
}

and also this:

$scope.$watch('inputName', function(value) {
    if (isValid(value)) {
        doSomething()
    }
});

The solution

<input type="text" ng-model="inputName" ng-valid="doSomething()" required>

How to install it

• Bower:

bower install --save ng-valid

• HTML:

<script src="bower_components/angular.js"></script>
<script src="bower_components/ng-valid/dist/ng-valid.min.js"></script>

• AngularJS:

var app = angular.module('app', ['ngValid']);

How to use it

Just add the ng-valid attribute and a method to be called when the input is valid:

<input type="text" ng-model="inputName" ng-valid="doSomething()" required>

You can also add the optional attribute ng-invalid to invoke a method when the input is not valid:

<input type="text" ng-model="inputName" ng-valid="doSomething()" ng-invalid="doSomethingElse()" required>
