backbone.js - Backbone JS、Marionette 和 Require JS

Question

我正在尝试使用 Marionette 来掌握 Backbone 和 Require JS，因为它有一些出色的功能。但是，我发现该应用程序可供查看时存在一些问题:

main.js

require(['application'], function(app){
app.start();
});

application.js

define([
'marionette',
'router'
], function(marionette, Router){

"use strict";

var app = new marionette.Application();

app.addRegions({
    header : 'header',
    main   : '#main'
});

app.addInitializer(function(){
    this.router = new Router();
});

return app;

});

仪表板.js

define([
'application',
'underscore',
'backbone', 
], function(app, _, Backbone) {
var DashboardView = Backbone.View.extend({

initialize: function() {
    console.log(app);
    $('a').click(function(e){
        e.preventDefault();
        app.router.navigate("claims", {
           trigger: true 
        });
    });
},

});
return DashboardView;
});

我在控制台日志中收到未定义信息？应用程序应该使用 requirejs 模块吗？

编辑:使用 require 更新

require.config({

paths: {
    'jquery'        : '../vendors/jquery-1.8.2',
    'underscore'    : '../vendors/underscore',
    'text'          : '../vendors/text',
    'json2'         : '../vendors/json2',
    'backbone'      : '../vendors/backbone',
    'marionette'    : '../vendors/plugins/backbone.marionette',
    'paginator'     : '../vendors/plugins/backbone.paginator',
    'relational'    : '../vendors/plugins/backbone.relational',
    'moment'        : '../vendors/moment',
    'bootstrap'     : '../vendors/bootstrap',
    'datepicker'    : '../vendors/plugins/bootstrap.datepicker',
    'templates'     : 'templates/'
},

shim: {

    backbone: {
        deps: ['underscore', 'jquery'],
        exports: 'Backbone'
    },
    marionette : {
        exports : 'Backbone.Marionette',
        deps : ['backbone']
    },
    paginator: {
        deps: [
        'backbone',
        'underscore',
        'jquery'
        ],
        exports: 'Backbone.Paginator'
    },
    relational: ['backbone'],
    underscore: {
        'exports': '_'
    },
    bootstrap: {
        deps: ['jquery'],
        exports: "bootstrap"
    },
    datepicker: {
        deps: ['jquery','bootstrap'],
        exports: "datepicker"
    },
    moment: {
        exports: 'moment'
    }
}

});

require(['application'], function(app){
    app.start();
});

路由器

define([
  'views/claims/PaginatedList',
  'views/dashboard/Dashboard'
  ], function(PaginatedClaimListView, DashboardView){

var Router = Backbone.Router.extend({

    routes: {

        "": "index",
        "claims": "claims"

    },

    initialize: function(){
        Backbone.history.start({
            pushState: true,
            root: '/app_dev.php/hera'
        });
    },

    index: function(){
        var dashboard = new DashboardView();
    },

    claims: function(){
        var claimListView = new PaginatedClaimListView();
    }

});

return Router;

});

Answer 1

我想我已经弄清楚了，即使我不是 100% 确定原因。

问题在于您的 Router 定义。将 View 与对 Application 的引用放在一起，可以使路由器在 main.js 中调用 app.start() 之前启动。事实上，如果您在 main.js 中放置一个 console.log(app) ，您会注意到它在dashboard.js 中的那个之后被调用。

这就是我解决这个问题的方法:

define(['backbone'], function(Backbone){

var Router = Backbone.Router.extend({

    routes: {
        "": "index",
        "claims": "claims"
    },

    initialize: function(){
        Backbone.history.start({
            pushState: true,
            root: '/app_dev.php/hera'
        });
    },

    index: function(){
        require(['views/dashboard/Dashboard'],function(DashboardView){
            var dashboard = new DashboardView();
        });
    },

    claims: function(){
        require(['views/claims/PaginatedList'],function(PaginatedClaimListView){
             var claimListView = new PaginatedClaimListView();
        });
    }

});

return Router;

});

我不确定是否有更好的解决方案可以让您的 View 在路由器中定义，无论如何，这有效并且会让您的路由器更轻，特别是当您的 View 数量增加时...
