Undercore & Backbone support for AMD (How to use Undercore & Backbone in Require.js)

Requirejs fills the gap in front-end modular development, Requirejs follows AMD (Asynchronous module definition, asynchronous module definition) specification, more and more frameworks support AMD, like the recent jquery, but some also do not support, like backbone, So how do you use backbone in Requirejs? Some of their features need to be set using Requirejs:

require.config ({    paths:{        ' jquery-1.7.2 ',        ' underscore ',        ' backbone ' ,        localstorage:' backbone-localstorage '    },    shim: {        backbone: {            deps: [' Underscore '],            ' Backbone '        },        localstorage:{            deps: [' Backbone '],             ' Store '}}    ); require ([function($, _, Backbone) {    }) ;
