The ng-click directive defines an AngularJS click event.

ng-click / ng-hide with toggle()
<!DOCTYPE html>

<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body>
<div ng-app="myApp" ng-controller="nameController">
<button ng-click="toggle()">Hide user</button>
<p ng-hide="toggleVar">
First Name: <input type="text" ng-model="firstName" placeholder="First name"><br />
Last Name: <input type="text" ng-model="lastName" placeholder="Last name"><br />
<br />
Full Name: {{firstName + " " + lastName}}
</p>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('nameController', function($scope) {
$scope.firstName = "Simon",
$scope.lastName = "Fairless"
$scope.toggleVar = false;
$scope.toggle = function() {
$scope.toggleVar = !$scope.toggleVar;
};
});
</script>
</body>
</html>
The code has a default property (a variable): $scope.toggleVar = false; The ng-hide directive sets the visibility of a <p> element with two input fields, depending on the value (true or false) of toggleVar.
The function toggle() toggles toggleVar between true and false.
The value ng-hide="true" makes the element invisible.
