如何等待相关模块的运行功能在初始化之前完成 [英] How to wait for dependent modules run function to be completed before initialization

问题描述

我正在尝试开发一个应用程序，其中一个模块将依赖于第二个模块.在第一个模块运行功能中，我试图使用http从服务器填充一些数据，但由于http调用是异步的，因此第二个模块将在第一个模块完成之前运行，并且结果未定义.下面的代码可以使情况更加清楚

I am trying to develop an app where one module will be dependent on second module. In the first module run function Im trying to fill templatecache with some data from server using http but since http calls are async my second module will run before the first is completed and I get undefined in the result. Below code would make situation more clear

   var app = angular.module('main', []).run(["$templateCache",'$http','$timeout', function ($templateCache,$http,$timeout) {
              $timeout(function () {
                  $templateCache.put('ajay', 'ajay');
              }, 1000);
          }
          ]);

          var secondapp = angular.module('plunker', ['main']);
          secondapp.controller('test', function ($scope, $templateCache, $timeout) {
              // get me undefined i want to wait until module main is finished running run function 
              alert($templateCache.get('ajay'));
          });

推荐答案

拥抱异步性:

 var app = angular.module('main', []).run(["$templateCache",'$http','$timeout', function ($templateCache,$http,$timeout) {
     $templateCache.put('ajay', $http.get("/data/ajay"));
 }
 ]);

 var secondapp = angular.module('plunker', ['main']);
 secondapp.controller('test', function ($scope, $templateCache, $timeout) {
     $templateCache.get('ajay').then(function (data) {
         alert(data);
     });
 });
