Question

在我引导AngularJS后，我似乎无法添加控制器。我得到的异常表明传递的控制器函数不是函数。但是，在Chrome调试器中，它显示为预期的功能。

（我意识到我没有使用初始化AngularJS的声明式样式，我正在探索框架。）

的JavaScript

function Bootstrapper() {

    var instance = new Object();

    instance.myModule = null;
    /*
     * Bootstrap AngularJS and initialize myModule
     */
    instance.bootstrapAngularJS = function() {
        instance.myModule = angular.module('myModule', []);
        angular.bootstrap(document, ['myModule']);
    };

    return instance;
}


function ControllerLibrary() {
}

ControllerLibrary.prototype.MediaLoaderController = function($scope) {
    $scope.status = "loading";
};

您必须在引导程序发生之前注册控制器，否则AngularJS无法找到控制器并抛出错误。请在此处查看工作plunker。摘录如下。

function Bootstrapper() {
    var instance = new Object();
    instance.myModule = angular.module('myModule', []);
    instance.bootstrapAngularJS = function() {
        angular.bootstrap(document, ['myModule']);
    };
    return instance;
}

$(document).ready( function(){
    bootstrapper = new Bootstrapper();
    controllerLibrary = new ControllerLibrary(); 
    bootstrapper.myModule.controller( "MediaLoaderController", controllerLibrary.MediaLoaderController );               
    bootstrapper.bootstrapAngularJS();
});

AngularJS控制器未注册
