jquery 动态记载css和js

 1 $.extend({
 2     includePath: '',
 3     include: function(file)
 4     {
 5         var files = typeof file == "string" ? [file] : file;
 6         for (var i = 0; i < files.length; i++)
 7         {
 8             var name = files[i].replace(/^\s|\s$/g, "");
 9             var att = name.split('.');
10             var ext = att[att.length - 1].toLowerCase();
11             var isCSS = ext == "css";
12             var tag = isCSS ? "link" : "script";
13             var attr = isCSS ? " type='text/css' rel='stylesheet' " : " language='javascript' type='text/javascript' ";
14             var link = (isCSS ? "href" : "src") + "='" + $.includePath + name + "'";
15             if ($(tag + "[" + link + "]").length == 0) $("head").append("<" + tag + attr + link + "></" + tag + ">");
16         }
17     }
18 });

使用方法
$.includePath = "http://localhost/";
$.include(['jquery.divbox.js','css/pop_win.css']);
