Method for AngularJS to Monitor Route Change

When using AngularJS, we need to do some processing when the route changes. At this time, we can listen for routing events, which are commonly used as $routeStartChange and $routeChangeSuccess. A complete example is as follows: 


<!DOCTYPE html>
<html>
<head>
 <meta charset="utf-8">
 <meta http-equiv="X-UA-Compatible" content="IE=edge">
 <title>AngularJS Listen for routing changes </title>
</head>
<body ng-app="ngRouteExample">
  <div id="navigation"> 
   <a href="#/home" rel="external nofollow" >Home</a>
   <a href="#/about" rel="external nofollow" >About</a>
  </div>
   
  <div ng-view></div>

  <script type="text/ng-template" id="home.html">
   <h1> Home </h1>
   <table>
    <tbody>
     <tr ng-repeat="x in records" style="background:#abcdef;">
      <td>{{x.Name}}</td>
      <td>{{x.Country}}</td> 
     </tr>     
    </tbody>
   </table>
  </script>

  <script type="text/ng-template" id="about.html">
   <h1> About </h1>
   <p> Try to enter in the input box: </p>
   <p> Name: <input type="text" ng-model="name"></p>
   <p> What you entered is:  {{name}}</p>
  </script>

  <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
  <script src="http://apps.bdimg.com/libs/angular-route/1.3.13/angular-route.js"></script>
  <script type="text/javascript">
  angular.module('ngRouteExample', ['ngRoute'])
  .config(function ($routeProvider) {
    $routeProvider.
    when('/home', {
      templateUrl: 'home.html',
      controller: 'HomeController'
    }).
    when('/about', {
      templateUrl: 'about.html',
      controller: 'AboutController'
    }).
    otherwise({
      redirectTo: '/home'
    });
  })
  .run(['$rootScope', '$location', function($rootScope, $location) {
    /*  Listen for changes in the state of a route  */
    $rootScope.$on('$routeChangeStart', function(evt, next, current){
     console.log('route begin change');
    }); 
    $rootScope.$on('$routeChangeSuccess', function(evt, current, previous) {
     console.log('route have already changed  : '+$location.path());
    }); 
  }])
  .controller('HomeController', function ($scope) { 
    $scope.records = [{
     "Name" : "Alfreds Futterkiste",
     "Country" : "Germany"
    },{
     "Name" : "Berglunds snabbköp",
     "Country" : "Sweden"
    },{
     "Name" : "Centro comercial Moctezuma",
     "Country" : "Mexico"
    },{
     "Name" : "Ernst Handel",
     "Country" : "Austria"
    }]
  })    
  .controller('AboutController', function ($scope) { 
   $scope.name = ' Hehe ';
  });
</script>  
</body>
</html>

The above example is AngularJS 1. Whether Angular2 can also be used, I haven't tried it yet. I have the opportunity to verify it and record it again ~ ~
