[jquery] go top / 맨위로 / 위로 올라가기

1. 부드럽게 올리기

<script>
var scrollUpDelay = 1;
var scrollUpSpeed = 30;
function scrollUp()
{
	 if(document.body.scrollTop<1)
 {
	 return;
 }
document.body.scrollTop=document.body.scrollTop-scrollUpSpeed;
setTimeout('scrollUp()',scrollUpDelay);
}
</script>
<a href="javascript:scrollUp()"><span style="color:#FFF076;">Go Top</span></a>

2. 간단

1. <a href="#">Go Top</a>
2. <a href="javascript:scroll(0,0)">Go Top</a>
