非常简洁的动态加载js和css的jquery plugin

核心提示:1// plugin author : [email protected]// plugin name : $.include3// $.include('file/ajaxa.js');$.include('file/ajaxa.css');4// or $.includePat

 

1// plugin author :  [email protected]
 2// plugin name : $.include
 3//     $.include('file/ajaxa.js');$.include('file/ajaxa.css');
 4//  or $.includePath  = 'file/';$.include(['ajaxa.js','ajaxa.css']);

 6$.extend({
 7    includePath: '',
 8    include: function(file) {
 9        var files = typeof file == "string" ? [file]:file;
10        for (var i = 0; i < files.length; i++) {
11            var name = files[i].replace(/^s|s$/g, "");
12            var att = name.split('.');
13            var ext = att[att.length - 1].toLowerCase();
14            var isCSS = ext == "css";
15            var tag = isCSS ? "link" : "script";
16            var attr = isCSS ? " type='text/css' rel='stylesheet' " : " language='javascript' type='text/javascript' ";
17            var link = (isCSS ? "href" : "src") + "='" + $.includePath + name + "'";
18            if ($(tag + "[" + link + "]").length == 0) document.write("<" + tag + attr + link + "></" + tag + ">");
19        }
20    }
21});

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"
  });
  .
});
.

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。
