AngularJS 定义全局变量的三种实现方式

'use strict';

/* App Module */

var test2 = 'tank';     //方法1，定义全局变量

var phonecatApp = angular.module('phonecatApp', [   //定义一个ng-app
 'ngRoute',
 'phonecatControllers',
 'tanktest'
]);

phonecatApp.value('test',{"test":"test222","test1":"test111"}); //方法2定义全局变量

phonecatApp.constant('constanttest', 'this is constanttest');  //方法3定义全局变量

phonecatApp.config(['$routeProvider',        //设置路由
 function($routeProvider) {
  $routeProvider.
   when('/phones', {
    templateUrl: 'partials/phone-list.html'   //这里没有设置controller，可以在模块中加上ng-controller
   }).
   when('/phones/:phoneId', {
    templateUrl: 'partials/phone-detail.html',
    controller: 'PhoneDetailCtrl'
   }).
   when('/login', {
    templateUrl: 'partials/login.html',
    controller: 'loginctrl'
   }).
   otherwise({
    redirectTo: '/login'
   });
 }]);

'use strict';

/* Controllers */

var phonecatControllers = angular.module('phonecatControllers', []);

phonecatControllers.controller('PhoneListCtrl', ['$scope','test','constanttest',
 function($scope,test,constanttest) {
  $scope.test = test;          //方法2，将全局变量赋值给$scope.test
  $scope.constanttest = constanttest;  //方法3，赋值
  $scope.test2 = test2;         //方法1，赋值
 }]);

<div data-ng-controller="PhoneListCtrl">
  {{test.test1}}
  {{constanttest}}
  {{test2}}
</div>
