angular 使用服务共享数据需要注意

        <div ng-controller=‘ctr1‘>
            <a href="#" ng-click=‘name()‘>1{{name1.name}}</a>
        </div>
        <div ng-controller=‘ctr2‘>
            <a href="#" ng-click=‘name()‘>1{{name1.name}}</a>
        </div>

　　　　　var app = angular.module(‘myapp‘,[]);
        app.factory(‘Data‘, function() {
        　　return {}
        });
        app.controller(‘ctr1‘,[‘$scope‘,‘$timeout‘,‘Data‘,function($scope,$timeout,Data){
            $scope.name1 = Data;//赋值时必须赋值整个Data
            $scope.name = function(){
                //不能直接给Data传值， 如：Data = {name:‘李四‘}; 
                //需先定义一个对象属性:如下
                Data.name = ‘李四‘;  
            }
        }]);
        app.controller(‘ctr2‘,[‘$scope‘,‘Data‘,function($scope,Data){
            $scope.name1 = Data;
            $scope.name = function(){
                Data.name = ‘王五‘;
            }
        }]);
