RequireJs入门实例

按照这篇文章自己动手写了一个例子，做了小修改

一：目录

二：源码

0，index.html

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title>Home</title>

    <style type="text/css">  
*{font-family:"微软雅黑","microsoft Yahei",verdana;}  
.text01{line-height:20px;font-size:13px;font-family:verdana;}  
pre{margin:0px;padding:2px 0px;font-size:13px;font-family:verdana;}  
.div01{border:1px solid red;text-align:left;padding:5px;  
}  
</style>  
</head>
<body>
<h4>requireJS 例子 example 01</h4>  
<div id="loadMsgCon" class="div01"></div>  
<script data-main="scripts/main" src="scripts/require.js"></script> <!--注意 requireJS 文件对应即可,同时data-main属性值写对即可-->  
</body>
</html>

1，main.js

//1，about require js config//配置信息  
;  
require.config({  
    //define all js file path base on this base path  
    //actually this can setting same to data-main attribute in script tag  
    //定义所有JS文件的基本路径,实际这可跟script标签的data-main有相同的根路径  
    baseUrl:"./scripts"   
  
    //define each js frame path, not need to add .js suffix name  
    //定义各个JS框架路径名,不用加后缀 .js  
    ,paths:{   
        "jquery":["http://libs.baidu.com/jquery/2.0.3/jquery", "lib/jquery/jquery.min"] //把对应的 jquery 这里写对即可  
        ,"workjs01":"work/workjs01"   
        ,"workjs02":"work/workjs02"  
        ,"underscore":"" //路径未提供，可网上搜索然后加上即可  
    }  
      
    //include NOT AMD specification js frame code  
    //包含其它非AMD规范的JS框架  
    ,shim:{   
        "underscore":{  
            "exports":"_"  
        }  
    }  
      
});  
  
//2，about load each js code basing on different dependency  
//按不同先后的依赖关系加载各个JS文件  
require(["jquery","workjs01"],function($,w1){  
    require(['workjs02']);  
});

2，workjs01.js

define(['jquery'],function($){  //注意模块的写法  
    //1,define intenal variable area//变量定义区  
    var myModule = {}; //推荐方式  
    
    var moduleName = "work module 01";  
    var version = "1.0.0";  
      
    //2,define intenal funciton area//函数定义区  
    var loadTip = function(tipMsg, refConId){  
        var tipMsg = tipMsg || "module is loaded finish.";  
        if(undefined === refConId || null === refConId || "" === refConId+""){  
            alert(tipMsg);  
        }else{  
            $('#' + (refConId+"")).html(tipMsg);  
        }  
    };  
      
    //3,should be return/output a object[exports/API] if other module need  
    //如有需要暴露(返回)本模块API(相关定义的变量和函数)给外部其它模块使用  
    myModule.moduleName = moduleName;  
    myModule.version = version;  
    myModule.loadTip = loadTip;   
    return myModule;  
      
    /* 
    //this is same to four line code upper//跟上面四行一样 
    return { 
        "moduleName":"work module 01" 
        ,"version":"1.0.0" 
        ,loadTip:loadTip 
    }; 
    */  
      
});

3, workjs02.js

define(['workjs01'],function(w01){  
    //1,define intenal variable area//变量定义区  
    var moduleName = "work module 02";  
    var moduleVersion = "1.0.0";  
      
    //2,define intenal funciton area//函数定义区  
    var setHtml = function(refId,strHtml){  
        if(undefined === refConId || null === refConId || "" === refConId+""){  
            return;  
        }else{  
            $('#' + (refId + "")).html(strHtml+"");  
        }  
    };  
      
    //3,auto run when js file is loaded finish  
    //在JS加载完,可在本模块尾部[return之前]运行某函数,即完成自动运行  
    w01.loadTip("本页文件都加载完成，本页设计 workjs01.js 文件依赖jquery, workjs02.js 依赖 workjs01.js","loadMsgCon");  
      
    //4,should be return/output a object[exports/API]  
    //如有需要暴露(返回)本模块API(相关定义的变量和函数)给外部其它模块使用  
    return {  
        "moduleName":moduleName  
        ,"version": moduleVersion  
    }  
      
});
