AngularJS动态加载控制器

本文介绍了AngularJS动态加载控制器的处理方法，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

我读了很多关于lazzy加载，但我使用$ routeProvider时面临的一个问题。

I read a lot about lazzy loading, but I am facing a problem when using $routeProvider.

我的目标是要加载的包含一个控制器一个JavaScript文件和一个路由添加到该控制器已加载previously。

My goal is to load a javascript file which contains a controller and add a route to this controller which has been loaded previously.

我的JavaScript文件的内容加载

angular.module('demoApp.modules').controller('MouseTestCtrlA', ['$scope', function ($scope) { console.log("MouseTestCtrlA"); $scope.name = "MouseTestCtrlA"; }]);

不包含此文件时的角度bootstap被调用。这意味着，我必须加载该文件并创建该控制器的路由。

This file is not included when angular bootstap is called. It means, I have to load the file and create a route to this controller.

首先，我开始写这已加载JavaScript文件下决心功能。但在声明声明路线我的控制器参数，给了我一个错误：

First, I started writing a resolve function which has to load the Javascript file. But declaring my controller parameter in route declaration gave me an error :

MouseTestCtrlA'不是一个函数，得到了不确定

'MouseTestCtrlA' is not a function, got undefined

下面是调用我试图设置：

Here is the call I am trying to set :

demoApp.routeProvider.when(module.action, {templateUrl: module.template, controller: module.controller, resolve : {deps: function() /*load JS file*/} });

从我读，控制器参数应该是已注册的控制器

From what I read, the controller parameter should be a registered controller

控制器 - {（字符串|函数（）=} - 控制器FN应该与新创建的范围，或者作为字符串传递的注册控制器的名称关联

controller – {(string|function()=} – Controller fn that should be associated with newly created scope or the name of a registered controller if passed as a string.

所以，我写了一个工厂，应该可以载入我的文件，然后（承诺的风格！）我尝试对子级声明一个新的路径。

So I write a factory which should be able to load my file and then (promise style!) I whould try to declare a new route.

这给了我类似下面，其中依赖性是JavaScript文件路径的数组加载：

It gave me something like below where dependencies is an array of javascript files' paths to load :

用法

ScriptLoader.load(module.dependencies).then(function () { demoApp.routeProvider.when(module.action, {templateUrl: 'my-template', controller: module.controller}); });

脚本加载

angular.module('demoApp.services').factory('ScriptLoader', ['$q', '$rootScope', function ($q, $rootScope) { return { load: function (dependencies) { var deferred = $q.defer(); require(dependencies, function () { $rootScope.$apply(function () { deferred.resolve(); }); }); return deferred.promise; } } }]);

问题

我仍然有这个JavaScript错误'MouseTestCtrlA'不是一个函数，得到了不确定的，这意味着角不可能解决MouseTestCtrlA作为注册控制器。

I still have this javascript error "'MouseTestCtrlA' is not a function, got undefined" which means Angular could not resolved 'MouseTestCtrlA' as a registered controller.

谁能帮我这一点吗？

推荐答案

重读这篇文章 ify.io/lazy-loading-in-angularjs/ 建议保持 $的ContentProvider 实例角应用中。

Re-reading this article ify.io/lazy-loading-in-angularjs/ suggested to keep a $contentProvider instance inside Angular App.

我来到了我的app.js这code

I came up with this code in my app.js

demoApp.config(function ($controllerProvider) { demoApp.controller = $controllerProvider.register; });

它让我写我的控制器有望在外部JavaScript文件：

It enables me to write my controller as expected in a external javascript file :

angular.module("demoApp").controller('MouseTestCtrlA', fn);

希望这可以帮助！

Hope this can help !
