angularjs 本地数据存储LocalStorage

//本地存储数据===================================.factory('locals',['$window',function($window){
      return{        //存储单个属性
        set :function(key,value){
          $window.localStorage[key]=value;
        },        //读取单个属性
        get:function(key,defaultValue){
          return  $window.localStorage[key] || defaultValue;
        },        //存储对象，以JSON格式存储
        setObject:function(key,value){
          $window.localStorage[key]=JSON.stringify(value);
        },        //读取对象
        getObject: function (key) {
          return JSON.parse($window.localStorage[key] || '{}');
        }

      }
  }]);

controller调用

添加对象 locals

.controller('loginController',function($scope, $ionicPopup, $state,locals){

使用存储或读取方法

//存储数据
 locals.set("username",user.username);
 locals.set("password",user.password);

 //读取数据
 console.log(locals.get("username",""));
