Javascript rquirejs-从全局空间获取问题

在我的应用程序中，我为我的应用程序创建了一个全局空间，上面写着

socialApp

。甚至在调用initialize方法之前，我就在窗口中声明

socialApp

，如下所示：

define([
    'jquery',
    'underscore',
    'backbone',
    'marionette',
    'scripts/appRoutes',
    'scripts/app/appModel',
    'scripts/app/layout/appLayout'], 
    function ($,_,Backbone,Marionette,Routes,appModel,appLayout) {
    "use strict";

    socialApp = window.socialApp || {}; // i am declared the socialApp here.
    socialApp = new Backbone.Marionette.Application();

    socialApp.addInitializer(function(options) {
        socialApp.NewRoute = new Routes;
        socialApp.GenModel = new appModel({router:socialApp.NewRoute}); //i am getting error saying "Uncaught ReferenceError: socialApp is not defined" - why?
        socialApp.Layout = new appLayout();
        socialApp.Layout.render();
        Backbone.history.start();
    });

这种情况并不总是发生，但在某些情况下，我会遇到这种错误。如何解决这个问题

在

appModel

中，我这样声明：

define(['jquery','underscore','backbone','marionette'], 
    function ($,_,Backbone,Marionette) {
    "use strict";
    socialApp = window.socialApp || {}; //exactly i am getting error from here on refresh some times..
    socialApp.Model = Backbone.Model.extend({
        initialize:function(currentRoute){
            this.router = currentRoute.router;
        }
    });
    return socialApp.Model;
});

我在哪里犯的错？有人能理解我吗？

你不能在AMD模块中声明全局变量，socialApp是模块本身中的局部变量。因此，请为socialApp变量声明AMD模块，如下所示：

define([
    'jquery',
    'underscore',
    'backbone',
    'marionette',
    'scripts/appRoutes',
    'scripts/app/appModel',
    'scripts/app/layout/appLayout'], 
    function ($,_,Backbone,Marionette,Routes,appModel,appLayout) {
    "use strict";

    socialApp = window.socialApp || {}; // i am declared the socialApp here.
    socialApp = new Backbone.Marionette.Application();

    socialApp.addInitializer(function(options) {
        socialApp.NewRoute = new Routes;
        socialApp.GenModel = new appModel({router:socialApp.NewRoute}); //i am getting error saying "Uncaught ReferenceError: socialApp is not defined" - why?
        socialApp.Layout = new appLayout();
        socialApp.Layout.render();
        Backbone.history.start();
    });

文件：socialApp.js

define(['marionette'], function(Marionette) {
   var socialApp = {};
   return socialApp;
});

define(['jquery','underscore','backbone','marionette', 'socialApp'], 
    function ($,_,Backbone,Marionette, socialApp) {

    socialApp.Model = Backbone.Model.extend({
        initialize:function(currentRoute){
            this.router = currentRoute.router;
        }
    });
    return socialApp.Model;
});

并要求您使用它的任何地方都提供socialApp

文件：appModel.js

define(['marionette'], function(Marionette) {
   var socialApp = {};
   return socialApp;
});

define(['jquery','underscore','backbone','marionette', 'socialApp'], 
    function ($,_,Backbone,Marionette, socialApp) {

    socialApp.Model = Backbone.Model.extend({
        initialize:function(currentRoute){
            this.router = currentRoute.router;
        }
    });
    return socialApp.Model;
});

或者，如果你坚持全局变量；在窗口内显式声明socialApp

替换

socialApp=window.socialApp | |{}与
window.socialApp=window.socialApp | |{}
您收到的错误是什么？我想，需要在模块中声明。它不作为
窗口工作。socialApp
-甚至。
