controller是相对独立的，也就是说，两个controller之间，内存是不共享的，这个controller是无法访问其他其他controller的属性或者方法的;
<!-- 一个controller -->
<div style="background: yellow;" ng-controller="worldCtrl">
{{author.name}}
<br/> {{author.sex}}
<button ng-click="update()">同步数据</button>
</div>
<!-- 另一个controller -->
<div ng-controller="helloCtrl">
{{author.name}}
<br/> {{author.sex}}
<button ng-click="updatePublic()">更新公有变量</button>
</div>
controller.js
var app = angular.module(‘Hello‘, []); app.controller(‘worldCtrl‘, function($scope, demoService) { $scope.author = demoService.publicAuthor; $scope.update = function() { //同步数据 $scope.author = demoService.publicAuthor; } }); app.controller(‘helloCtrl‘, function($scope, demoService) { $scope.author = demoService.publicAuthor; $scope.updatePublic = function() { //更新您数据 demoService.publicAuthor = { name: ‘fei‘, sex: ‘female‘ } $scope.author = demoService.publicAuthor; } });
service.js
app.service(‘demoService‘, function () { var privateAuthor = { //私有变量 name: ‘jack‘, sex: ‘male‘ } this.publicAuthor = { //共有变量 name: ‘rose‘, sex: ‘female‘ } this.getPriAuthor = function () { //获取私有变量 return publicAuthor; } });
end.
