Dojo中数组arrayUtil的几个简单方法示例

懒得写文字,直接贴index.html代码:

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4     <meta charset="UTF-8" >
 5     <title>Tutorial: Hello Dojo!</title>
 6 </head>

 8 <body>
 9     <h1 id="greeting">Hello</h1>
10 
11     <script type="text/javascript">

13             async : true,

15             packages : [{
16                 name : "dojo",
17                 location :　location.pathname.replace(/\/[^/]*$/,'')+"/../dojo-release-1.10.4/dojo"

 文件夹结构如下:

--myTestDemos
    |--array
        |--index.html
    |--dojo-release-1.10.4
        |--dojo
        |--dijit
        |--dojox
