$.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 + ">");

        }

    }

});

$.include(['http://image.esunny.com/script/jquery.divbox.js','/css/pop_win.css']);
