 　　app.js

var app = angular.module(\'myApp\', [\'ngRoute\', \'demoService\', ]);

　　

　　app-route.js

//路由配置
app.config([\'$routeProvider\', function ($routeProvider) {
    $routeProvider
    .when(\'/\', { templateUrl: \'../Scripts/core/views/demo/index.html\', controller: \'demoController\' })

　　app-service.js

//服务
