Angular路由中常見錯誤描述

一、錯誤描述：Error: [ng:areq] http://errors.AngularJS.org/1.4.8/ng/areq?p0=HelloCtrl&p1=not%20a%20function%2C%20got%20undefined

Angular中出現這種錯誤是由於沒有引入controller致使的，修改以下：

只須要在模塊中加入controller

<script>
    var app=angular.module('myapp',['ngRoute']);
    app.config(['$routeProvider',function($routeProvider) {
        $routeProvider.
        when('/home',{
            templateUrl:'home.html',
            controller:''
        }).
        when('/cn',{
            templateUrl:'cn.html',
            controller:''
        }).
        when('/other',{
            templateUrl:'other.html',
            controller:''
        }).
        otherwise({
            redirectTo:'/home'
        })
    }])
        app.controller('myctrl',function($scope) {
            
        })
</script>
