仅在需要AngularJS时注入模块依赖项（如插件） [英] Inject module dependency (like plugin) only if needed AngularJS

问题描述

我有2页（我没有使用 angular 的 routing - 这个约束）。

其中一个我想使用指令 ui-grid ，如下图所示： data-lang =jsdata-hide =falsedata-console =falsedata-babel =false>

  var app = angular.module（'myApp'，['ui.grid']）; app.controller（'mainCtrl'，function（$ scope）{$ scope。 myData = [{firstName：Cox，lastName：Carney，company：Enormo，employed：true}，{firstName：Lorraine，lastName： ，公司：Comveyer，雇用：false}，{firstName：Nancy，lastName：Waters，company：Fuelton，employed：false}]; }）;  

 < script src =http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular。 js>< / script>< script src =http://ui-grid.info/release/ui-grid-unstable.js>< / script>< link rel =stylesheet href =http://ui-grid.info/release/ui-grid-unstable.csstype =text / css>< div ng-app =myApp> < div ng-controller =mainCtrl> < div id =grid1ui-grid ={data：myData}class =grid>< / div> < / div>< / div>  

我的问题是如果在任何情况下，只有当我需要它时，才会向应用程序注入 ui-grid 依赖项。

类似于：

  app.controller（'mainCtrl'，function（$ scope）{
 app 。$ inject（'ui-grid'）; 
}）; 
  

更新

<

  var ui_grid = $ injector.get（'ui-grid'）; 
  

但是我有一个错误：

< blockquote>

未知提供者：ui-gridProvider< - ui-grid

解决方案

Core Angular API不提供此功能。 ocLazyLoad 是用于在Angular中延迟加载模块和组件的流行库。

您可以在其页面上找到更多信息：

或GitHub存储库：

I have 2 pages (I don't use the angular's routing - This constraint).

In one of them I want to use the directive ui-grid like in this demo:

var app = angular.module('myApp', ['ui.grid']);
app.controller('mainCtrl', function($scope) {
  $scope.myData = [
    {
        "firstName": "Cox",
        "lastName": "Carney",
        "company": "Enormo",
        "employed": true
    },
    {
        "firstName": "Lorraine",
        "lastName": "Wise",
        "company": "Comveyer",
        "employed": false
    },
    {
        "firstName": "Nancy",
        "lastName": "Waters",
        "company": "Fuelton",
        "employed": false
    }
  ];
});

<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.js"></script>
<script src="http://ui-grid.info/release/ui-grid-unstable.js"></script>
<link rel="stylesheet" href="http://ui-grid.info/release/ui-grid-unstable.css" type="text/css">

<div ng-app="myApp">
  <div ng-controller="mainCtrl">
    <div id="grid1" ui-grid="{ data: myData }" class="grid"></div>
  </div>
</div>

My question is if there is a way to not inject the ui-grid dependency to the app in any case but only when I need it.

Something like:

app.controller('mainCtrl', function($scope) {
   app.$inject('ui-grid');
});

Update

I tried to do:

var ui_grid = $injector.get('ui-grid');

But I've got an error:

Unknown provider: ui-gridProvider <- ui-grid

http://errors.angularjs.org/1.2.26/$injector/unpr?p0=ui-gridProvider%20%3C-%20ui-grid

解决方案

Core Angular API does not provide this feature. ocLazyLoad is the popular library for lazy loading of modules and components in Angular.

You can find more info on their page: https://oclazyload.readme.io

or the GitHub repository: https://github.com/ocombe/ocLazyLoad
