Ionic assigns the data returned asynchronously in the service to the controller's $scope

1. Get data instance asynchronously in service

Angular.module (' starter.services ', []). Factory (' Chats ',function($http, $q) {//define service for chats  return{all:function() {//The all method gets the data asynchronously      varDeferred= $q. Defer ();//Define deferred      varPromise=deferred.promise;//Define Promise$http. Get (' http://localhost:3000/lists '). Success (function(data,status,headers,config) {//executes the Deferred.resolve method, passing in the returned data as a parameterdeferred.resolve (data); })      //Back to Promise      returnpromise; }  };});

2, the controller executes chats's All method, and assigns the returned data to the $scope's items, where result is the data returned asynchronously in the service's All method

Angular.module (' starter.controllers ', []). Controller (function($scope, Chats) {    Chats.all (). Then (function(result) {      = result;    },function() {      Console.log (' goodsservice get error ');    } )
