如果变量是数组,那么我可以将对象推入其中并在控制器内获取值,但是如果直接将对象分配给该变量,则无法执行该操作

请任何人帮助我实现这一目标。

这是小提琴链接

角度代码:

//angular.js example for factory vs service
var app = angular.module('myApp', []);

app.factory('testFactory', function(){
     var countF={};//= [{abc:'aaa'}];
    return {

        getCount : function () {

            return countF;
        },
        incrementCount:function(){
          //countF.push({aaaa:'jshfdkjsf'});
           countF={aaaa:'jshfdkjsf'};
            //return countF;
        }
    }
});

function FactoryCtrl($scope,testFactory)
{
    $scope.countFactory = testFactory.getCount();
    $scope.clickF = function () {
       testFactory.incrementCount();
       // console.log($scope.countFactory);
    };
}


HTML代码:

<div ng-controller="FactoryCtrl">

    <!--  this is never updated after count is changed! -->
    <p> This is my countFactory variable : {{countFactory}}</p>

    <p> This is my updated after click variable : {{countF}}</p>

    <button ng-click="clickF()" >Factory ++ </button>
</div>

最佳答案

您的问题出在此代码中-

 incrementCount:function(){
        //countF.push({aaaa:'jshfdkjsf'});
        countF={aaaa:'jshfdkjsf'};
        //return countF;
 }


在这里,您没有在重新创建countF对象的aaa属性

初始化-countF = {};

添加属性-

  right `countF.aaa = "value";`

  wrong `countF = { aaa : 'value' }`


解决方案-

incrementCount:function(){
    countF.aaaa = 'jshfdkjsf';
 }
