当您只能访问模块变量时注入模块 [英] injecting module when you have access only to a module variable
本文介绍了当您只能访问模块变量时注入模块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
假设您有一个
var app = angular.module('Mod1',[])
现在您需要向该模块注入其他内容，但是您无法更改该行，只能访问app变量.
and now you need to inject something else to that module, but you can't change that line, you only have access to the app variable.
所以这行不通，对吧?
var mod2 = angular.module('mod2',[]).factory('$myService', function(){
return { do: function(){alert('doing'); }
})
app.directive('foo',[$myService]) // $myService here is undefined
您当然可以随时这样做:
Of course you can always do:
injector = angular.injector(['mod2'])
$myService = injector.get('$myService')
尽管我想知道是否还有更优雅的解决方案
Although I'm wondering if there's more elegant solution
推荐答案
这取决于您的代码何时实际运行. 我尝试了这个小酒杯，它奏效了.
It depends on when is your code actually run. I tried this plunker and it worked.
app.js
var app = angular.module('plunker', []);
myModule.js
myModule.js
var myModule = angular.module('myModule', []);
myModule.service('MyService', function() {
return {test: 'MyService'};
});
app.requires.push('myModule');
app.controller('MainCtrl', ['$scope','MyService', function($scope, MyService) {
$scope.name = MyService.test;
}]);
index.html
index.html
<head>
<script src="app.js"></script>
<script src="myModule.js"></script>
</head>
您需要在加载app.js之后但在相同的javascript执行序列中添加额外的模块.超时和异步加载对我来说失败.
You need to add your extra modules after the app.js is loaded but within the same javascript execution sequence. Timeouts and async loading failed for me.
