AngularJS监听路由变化的方法

使用AngularJS时，当路由发生改变时，我们需要做某些处理，此时可以监听路由事件，常用的是$routeStartChange, $routeChangeSuccess。完整例子如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>AngularJS监听路由变化</title>
</head>
<body ng-app="ngRouteExample">
<div id="navigation">
<a href="#/home" rel="external nofollow" >Home</a>
<a href="#/about" rel="external nofollow" >About</a>
</div>
<div ng-view></div>
<script type="text/ng-template" id="home.html">
<h1> Home </h1>
<table>
<tbody>
<tr ng-repeat="x in records" style="background:#abcdef;">
<td>{{x.Name}}</td>
<td>{{x.Country}}</td>
</tr>
</tbody>
</table>
</script>
<script type="text/ng-template" id="about.html">
<h1> About </h1>
<p>在输入框中尝试输入：</p>
<p>姓名：<input type="text" ng-model="name"></p>
<p>你输入的为： {{name}}</p>
</script>
<script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
<script src="http://apps.bdimg.com/libs/angular-route/1.3.13/angular-route.js"></script>
<script type="text/javascript">
angular.module('ngRouteExample', ['ngRoute'])
.config(function ($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) {
/* 监听路由的状态变化 */
$rootScope.$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 = '呵呵';
});
</script>
</body>
</html>
上述的例子是AngularJS 1的，对于Angular2是否也可以用，还没尝试过，有机会验证了再记录下咯~~
