使用jquery动态加载js，css文件

复制代码 代码如下:

$.extend({

includePath: '',

include: function(file) {

var files = typeof file == "string" ? [file]:file;

for (var i = 0; i < files.length; i++) {

var name = files[i].replace(/^s|s$/g, "");

var att = name.split('.');

var ext = att[att.length - 1].toLowerCase();

var isCSS = ext == "css";

var tag = isCSS ? "link" : "script";

var attr = isCSS ? " type='text/css' rel='stylesheet' " : " language='javascript' type='text/javascript' ";

var link = (isCSS ? "href" : "src") + "='" + $.includePath + name + "'";

if ($(tag + "[" + link + "]").length == 0) document.write("<" + tag + attr + link + "></" + tag + ">");

}

}

});

//使用方法

$.includePath = 'http://hi.baidu.com/javascript/';

$.include(['json2.js', 'jquery.tree.js', 'jquery.tree.css']);
