var _sn = ["df/common", "df/home2010"];

var _su = "http://www.jb51.net/skin/";

var Swidth = screen.width; var _se, _st;

for (i in _sn) {

_se = document.createElement("link");

_se.type = "text/css";

_se.rel = "stylesheet";

if (Swidth >= 1280) {

_st = _su + _sn[i] + ".w.css";

} else {

_st = _su + _sn[i] + ".css";

}

_se.href = _st;

document.getElementsByTagName("head")[0].appendChild(_se);
