angular.js - controller获取service的值

问题描述

var sdApp = angular.module('sdApp', []);//订单;//服务;sdApp.service('orderService', ['$http', function(a){ var s = {searchData : function(data){ a({method: 'post',url: '/?app_act=/orders/ajax_order_list&app_fmt=json',data: $.param(data),headers: {'Content-Type':'application/x-www-form-urlencoded', 'x-camnpr-uid':'1000'} }).success(function(res){console.log(res);return res; });} }; return s;}]);//控制;sdApp.controller('orderSearchCtrl', ['$scope', '$http', 'orderService', function(a, b, c){ //搜索; a.search = function(){a.res = c.searchData(a.orData);console.log(a.res); };}]);

为什么console.log出来的a.res是undefined？

问题解答

searchData()没有return一个返回值，默认就是undefined
