dojo 二 AMD模块
可参考官方教程:http://dojotoolkit.org/documentation/tutorials/1.7/hello_dojo/
教程里主要定义了两个方法,setText设置文本内容和restoreText重置文本内容。
这两个方法通过dojo.define这个方法来定义。
// In 
demo/myModule.js (which means this code defines// the 
"demo/myModule" module):define([    // The dojo/dom module is required by this 
module, so it goes    // in this list of 
dependencies.    "dojo/dom"], 
function(dom){    // Once all modules in the dependency list 
have loaded, this    // function is called to define the 
demo/myModule module.    //    // The dojo/dom module is passed as the 
first argument to this    // function; additional modules in the 
dependency list would be    // passed in as subsequent 
arguments.    var oldText = 
{};    // This returned object becomes the defined 
value of this module    return {        setText: 
function(id, text){            var node = 
dom.byId(id);            oldText[id] = 
node.innerHTML;            node.innerHTML = 
text;        },        restoreText: 
function(id){            var node = 
dom.byId(id);            node.innerHTML = 
oldText[id];            delete 
oldText[id];        }    };});
define 方法引用了必要的类,就像java 中的 
import;并且还包含了对业务逻辑的实现,
并通过return来返回,以上就是myModule.js文件的全部内容。
那么在html页面里,通过dojo.require来加载上面的js代码,
// 
Require the module we just createdrequire(["demo/myModule"], 
function(myModule){    // Use our module to change the text in the 
greeting    myModule.setText("greeting", 
"Hello Dojo!");    // After a few seconds, restore the text to 
its original state    setTimeout(function(){        myModule.restoreText("greeting");    }, 3000);});
在这里暂且先总结为:dojo.define 方法仅用于定义和声明,dojo.require 方法仅用于异步加载js文件
