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~~
