// plugin author : chenjinfa@gmail.com
2// plugin name : $.include

$.extend({

includePath: '',

include: function(file) {

10 for (var i = 0; i < files.length; i++) {
11 var name = files[i].replace(/^\s|\s$/g, "");
12 var att = name.split('.');
13 var ext = att[att.length - 1].toLowerCase();
14 var isCSS = ext == "css";

放在javascript文件头部，就像C#（using...）或Java（import ...）
示例：部门管理页 Department.aspx
注：因编辑器的问题，内容（http://www.cnblogs.com）原文是“. . / . . /”
.<head>
<link rel="stylesheet" href="http://www.cnblogs.com/css/common.css" type="text/css"/>
<script src="http://www.cnblogs.com/javascript/jquery.js" type="text/javascript"></script>
<script src="http://www.cnblogs.com/javascript/common.js" type="text/javascript"></script>
<script src="DepartmentInfo.js" type="text/javascript"></script>
</head>
include plugin 代码 放在公共common.js。
DepartmentInfo.js 文件代码
$.includePath = 'http://www.cnblogs.com/javascript/';
$.include(['json2.js', 'jquery.tree.js', 'jquery.tree.css']);
$(function() {
$("#depTree").tree({
url: "http://www.cnblogs.com/service/ES_SYSTEM.svc/DEP_INFO_Tree"
});
.
});
.
$.include(['json2.js', 'jquery.tree.js', 'jquery.tree.css']);
$(function() {
$("#depTree").tree({
url: "http://www.cnblogs.com/service/ES_SYSTEM.svc/DEP_INFO_Tree"
});
.});
.
这样写法挺好看的。
以后有空再我发表我写的整个项目及体会。基于asp.net Data Service 和 jquery的一套框架系统，名称定为：“E-Frame“，实现了基于角色权限系统等功能。
