ngClass directive

The ngClass directive is used every time you need to dynamically apply a class to an element by providing the name of the class in a data-binding expression.

The following code shows the application of the ngClass directive.
<!doctype html>
<html ng-app="parking">
<script src="angular.js"></script>
var parking = angular.module("parking", []);
parking.controller("parkingCtrl", function($scope) {
$scope.appTitle = "Parking";
$ = [];
$scope.park = function(car) {
car.entrance = new Date();
delete $;
.selected {
background-color: #FAFAD2;
<body ng-controller="parkingCtrl">
<h3 ng-bind="appTitle"></h3>
