我正在使用Backbone,Marionette和RequireJS构建应用程序,如果可以通过任何方式改进/改进应用程序启动,我希望由一些经验丰富的人员运行。
文件夹结构:
index.html
js/
collections/
libs/
backbone.js
marionette.js
require.js
...
models/
views/
app.js
init.js
router.js
目前应用程序的引导程序如下:
index.html
将requireJS入口点定义为:
<script data-main="js/init" src="js/libs/require.js"></script>
init.js
执行RequireJS配置并执行:
require(['app'], function(App){
App.start();
});
app.js
中的应用模块:
App = new Backbone.Marionette.Application();
App.addInitializer(function (options) {
// initialize the Router; will only setup the routes and corresponding callbacks; not history.start()
App.router = new Router();
// initialize Marionette regions
App.addRegions({
'header': '#header',
'main': '#main',
'footer': '#footer'
});
});
App.on('start', function(options) {
Backbone.history && Backbone.history.start() || console.error('No "Backbone.history" to .start()');
});
return App;
router.js
中的路由器模块:
return Backbone.Router.extend({
routes: {
'panel/:handle': 'showPanel',
},
showPanel: function (handle) {
require(['app'], function (App) {
App.main.show(new Panel_v({userHandle: handle}));
});
}
});
有没有办法让路由器模块不那么复杂?我通过这种方式解决了由App-&gt; Router-&gt; App。
形成的循环依赖问题还有其他建议吗?

我最近来到这个解决方案,在main.js文件中加入App和Router:
App.js
define(['marionette'], function(Marionette) {
var App;
App = new Backbone.Marionette.Application();
App.vars = {};
App.addRegions({
headerRegion: "#header-region",
mainRegion: "#main-region",
footerRegion: "#footer-region",
dialogsRegion: "#dialogs"
});
App.vent.on("routing:started", function() {
Backbone.history.start();
});
return App;
});
Router.js
define(['marionette', 'app'], function(Marionette, App) {
var appRouter, routerController;
routerController = {
showViaggi: function() {
return require(['modules/viaggi/viaggi'], function(Viaggi) {
App.Modules.viaggi = new Viaggi();
return App.Modules.viaggi.start();
});
}
};
return appRouter = Backbone.Marionette.AppRouter.extend({
appRoutes: {
'viaggi': 'showViaggi'
},
controller: routerController
});
});
Main.js,我的初始脚本加载了Require.js
define(['app', 'routers/appRouter'], function(App,appRouter) {
App.addInitializer(function() {
App.Router = new appRouter;
return App.vent.trigger("routing:started");
});
return App.start();
});
