<script type="text/javascript">
var hd = document.getElementsByClassName("hd")[0].getElementsByTagName("li");
var bd = document.getElementsByClassName("bd")[0].getElementsByTagName("li");
for (var i = 0; i < hd.length; i++) {
hd[i].onclick = function(){
doTabs(this);
}
}
function doTabs(obj){
for (var i = 0; i < hd.length; i++) {
if(hd[i]==obj){
hd[i].className = "current";
bd[i].className = "current";
}else{
hd[i].className = "";
bd[i].className = "";
}
}
}
</script>
