注意:这是旧版本AngularJS的正确答案。有关更新的版本,请参阅此问题。
$scope.$on('$routeChangeStart', function($event, next, current) {
// ... you could trigger something here ...
});
以下事件也可用(它们的回调函数采用不同的参数):
请参阅$ route文档。
还有其他两个未记录的事件:
$rootScope.$on("$routeChangeStart", function (event, next, current) {
现在。
如果您不想将手表放在特定的控制器中,则可以在Angular应用中为整个应用添加手表 run()
var myApp = angular.module('myApp', []);
myApp.run(function($rootScope) {
$rootScope.$on("$locationChangeStart", function(event, next, current) {
// handle route changes
});
});
$rootScope.$on( "$routeChangeStart", function(event, next, current) {
//..do something
//event.stopPropagation(); //if you don't want event to bubble up
});
$rootScope.$on( "$routeChangeStart", function(event, next, current) {
//if you want to interrupt going to another location.
event.preventDefault(); });
这是针对整个初学者的...就像我这样:
HTML:
<ul>
<li>
<a href="#"> Home </a>
</li>
<li>
<a href="#Info"> Info </a>
</li>
</ul>
<div ng-app="myApp" ng-controller="MainCtrl">
<div ng-view>
</div>
</div>
角度:
//Create App
var app = angular.module("myApp", ["ngRoute"]);
//Configure routes
app.config(function ($routeProvider) {
$routeProvider
.otherwise({ template: "<p>Coming soon</p>" })
.when("/", {
template: "<p>Home information</p>"
})
.when("/Info", {
template: "<p>Basic information</p>"
//templateUrl: "/content/views/Info.html"
});
});
//Controller
app.controller('MainCtrl', function ($scope, $rootScope, $location) {
$scope.location = $location.path();
$rootScope.$on('$routeChangeStart', function () {
console.log("routeChangeStart");
//Place code here:....
});
});
希望这对像我这样的初学者有所帮助。这是完整的工作示例:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular-route.min.js"></script>
</head>
<body>
<ul>
<li>
<a href="#"> Home </a>
</li>
<li>
<a href="#Info"> Info </a>
</li>
</ul>
<div ng-app="myApp" ng-controller="MainCtrl">
<div ng-view>
</div>
</div>
<script>
//Create App
var app = angular.module("myApp", ["ngRoute"]);

})
.when("/Info", {
