问题描述

我想通过Requirejs模块化骨干我的应用程序,但我似乎无法得到Requirejs包括骨干。这里是我的main.js是被从索引页包括:

I am trying to modularize my Backbone app through Requirejs, but I cannot seem to get Requirejs to include Backbone. Here is my main.js that gets included from the index page:

require.config({
    baseUrl: '/static/js/',
    paths: {
        jquery: 'libs/jquery/jquery-min',
        underscore: 'libs/underscore/underscore-min',
        backbone: 'libs/backbone/backbone-min',
        text: 'libs/require/text',
    },
});

require(['/static/js/views/app.js'], function(AppView) {
    var appView = new AppView;
});

下面是我的app.js,但未通过上面的文件包括:

Here is my app.js that gets included from the above file:

define([
    'jquery',
    'underscore',
    'backbone',
], function($, _, Backbone) {
  console.log($);
  console.log(_);
  console.log("inside of the app js file");
    var AppView = Backbone.View.extend({

        initialize: function() {
            console.log("inside of appview initialize");
        },

    });
});

以下信息会在我的谷歌浏览器的控制台打印出来:

The following information gets printed out in my Google Chrome console:

function (a,b){return new e.fn.init(a,b,h)}
app.js:7undefined
app.js:8inside of the app js file
app.js:9Uncaught TypeError: Cannot read property 'View' of undefined

为$的定义工作,但对于_和骨干的定义不工作。他们拿出为未定义。任何想法,为什么发生这种情况?

The definition for $ works, but the definitions for _ and Backbone do not work. They come up as undefined. Any idea why this is happening?

推荐答案

我建议你使用已绑定的jQuery的requireJS的版本。它会为你节省很多安装的痛苦。你可以在这里阅读细节: http://requirejs.org/docs/jquery.html 并在这里下载文件: https://github.com/jrburke/require-jquery

I recommend you use the version of requireJS that has jQuery bundled. It will save you much setup pain. You can read the details here: http://requirejs.org/docs/jquery.html and download the files here: https://github.com/jrburke/require-jquery

在他们自己的话说:

使用RequireJS,脚本可以以不同的顺序比他们指定的顺序加载。这可能会导致该承担的jQuery已经加载jQuery插件的问题。使用组合RequireJS + jQuery的文件,确保jQuery是在页面之前任何jQuery插件负载。

With RequireJS, scripts can load in a different order than the order they are specified. This can cause problems for jQuery plugins that assume jQuery is already loaded. Using the combined RequireJS + jQUery file makes sure jQuery is in the page before any jQuery plugins load.

这应该采取与requireJS正确加载的jQuery的护理:

This should take care of loading jQuery properly with requireJS:

<script data-main="js/main" src="js/require-jquery.js"></script>

Main.js

有两点要注意这里:


  • 无需重新定义jQuery的路径,因为这已经照顾

  • 您还必须标明的jQuery作为必需的模块

  • (我不得不更新的路径有他们在我的系统工作)

code:

require.config({
    baseUrl: 'js/',
    paths: {
        underscore: 'libs/underscore-min',
        backbone: 'libs/backbone-min',
    },
});

require(['jquery', 'app'], function($, AppView) {
    console.log("done w/ requires");
    console.log($)
    console.log(AppView)
    var appView = new AppView;
});

app.js

一对夫妇的注意事项:


  • 您只能在回调加载它们,如果它们已被定义为模块后,检索JS文件。所以功能($,_,骨干)将无法给你。

  • 您必须返回你的对象,以便它可以在main.js回调使用(返回APPVIEW)

code:

define(
    [
    'jquery',
    'underscore',
    'backbone',
    ],
    function() {
        console.log($);
        console.log(_);
        console.log(Backbone);
        console.log("inside of the app js file");
        return AppView = Backbone.View.extend({
            initialize: function() {
            console.log("inside of appview initialize");
        },
    });
});

控制台

随着地方,code,这是控制台输出:

With that code in place, this is the console output:

function ( selector, context ) {
    // The jQuery object is actually just the init constructor 'enhanced'
    return new jQuery.fn.init( selector, context, rootjQuery );
    } [app.js:8]

function (a){return new m(a)} [app.js:9]

Object [app.js:10]

inside of the app js file [app.js:11]

done w/ requires main.js:21

function ( selector, context ) {
    // The jQuery object is actually just the init constructor 'enhanced'
    return new jQuery.fn.init( selector, context, rootjQuery );
} [main.js:22]

function (){a.apply(this,arguments)} [main.js:23]

inside of appview initialize [app.js:15]
