如何使jQuery插件（jquery.cookie，jquery.validate.unobtrusive）可通過requirejs和use.js加載

Question

我一直在嘗試從http://net.tutsplus.com/tutorials/javascript-ajax/building-a-scalable-app-with-backbone-js/擴展模板應用程序。 通過以下實現，我將面臨“ Uncaught ReferenceError：未定義jQuery”。 有人可以讓我知道造成問題的原因是什么。

config.js
// Set the require.js configuration for your application.
require.config({
  // Initialize the application with the main application file
  deps: ["main"],
  urlArgs: "bust=" + (new Date()).getTime(),
  waitSeconds: 15,
  paths: {
    // JavaScript folders
    libs: "../assets/js/libs",
    plugins: "../assets/js/plugins",

    // Libraries
    //jquery: "../assets/js/libs/jquery",
    jquery: "http://code.jquery.com/jquery-1.7.min",
    jquerycookie:  "../assets/js/libs/jquery.cookie",
    jqueryDataTables: "../assets/js/libs/jquery.dataTables.min",
    jqueryValidate: "../assets/js/libs/jquery.validate",
    jqueryValidateUnobtrusive: "../assets/js/libs/jquery.validate.unobtrusive",
    underscore: "../assets/js/libs/underscore",
    backbone: "../assets/js/libs/backbone",
    highcharts:  "../assets/js/libs/highcharts/highcharts",
    highstock:  "../assets/js/libs/highcharts/highstock",
    easyXDM:     "../assets/js/libs/easyXDM/easyXDM.min",
    dateFormat: "../assets/js/libs/date.format",
    // Shim Plugin
    use: "../assets/js/plugins/use"
  },
  priority: [
        'jquery',
        'jquerycookie',
        'jqueryValidate',
        'jqueryValidateUnobtrusive',
        'underscore',
        'easyXDM',
        "highcharts",
        "highstock",
        "dateFormat"
  ],
  use: {
    backbone: {
      deps: ["use!underscore", "jquery"],
      attach: "Backbone"
    },
    jqueryDataTables: {
        deps: ["jquery"]
    },
    jqueryValidate: {
        deps: ["jquery"]
    },
    jqueryValidateUnobtrusive: {
        deps: ["jquery", "jqueryValidate"]
    },
    jquerycookie: {
        deps: ["jquery"]
    },
    underscore: {
      attach: "_"
    },
    highcharts: {
      exports: 'Highcharts'
    },
    highstock: {
      exports: 'highstock'
    }
  }
});

main.js
require([
    "namespace",

    // Libs
    "jquery",
    "jqueryDataTables",
    "use!backbone",

    'jquerycookie',
    'jqueryValidate',
    'jqueryValidateUnobtrusive',
    'highcharts',

    // Modules
    "modules/tricklebot",
    "modules/home",
    "modules/dashboard",
    "modules/profile",
    "modules/transactions",
    "modules/analysis",
    "modules/signup",

],

function(namespace, $, jqDT, Backbone,
         jqCookie, jqValidate, jqValidateUnobtrusive, highcharts,       
         tricklebot, Home, Dashboard, Profile, Transactions, Analysis, Signup) {
......

我認為您正在遵循一個過時的教程，require.js配置中的use和priority已被shim替換，請查看： https : //github.com/jrburke/requirejs/wiki/Upgradeing-to-RequireJS-2.0

Answer 2

現在，有一種使用較新的RequireJS來加載普通JS文件的簡便方法，該方法可以避免所有路徑，映射和勻稱廢話：

require(['jquery'],function($){
    require(
        [
            'path/to/my/module'
            , 'path/to/plugin1' // <- plain js file but OMIT ".js" extension in the ID
            , 'path/to/plugin2' // <- plain js file but OMIT ".js" extension in the ID
            , 'path/to/plugin3' // <- plain js file but OMIT ".js" extension in the ID
        ]
        , function(myModule /*, it does not matter what plugins return*/){
            // jQuery will have all the above plugins applied by now
            // because they apply their code to global window.jQuery
            // just start using them
            $(selector).plugin1(blah)
        }
    )
})

使用不帶“ .js”的計划JavaScript文件，使其像模塊ID一樣受所有“映射”和“路徑”修改的約束，但是當/如果普通JS文件不是模塊，仍然不會抱怨。

這些模塊不會在以后的加載中重新加載，因為它們是從第一次緩存開始的。 利潤！
