我的意思是要用鼠标单击层，然后可以拉着层改变位置。
有没有办法？
以下代码加入<body>区域 就可以了
<script language="javascript">
var IE5=(document.getElementById && document.all)? true : false;
var W3C=(document.getElementById)? true: false;
var currIDb=null, currIDs=null, xoff=0, yoff=0; zctr=0; totz=0;
function trackmouse(evt){
if((currIDb!=null) && (currIDs!=null)){
var x=(IE5)? event.clientX+document.body.scrollLeft : evt.pageX;
var y=(IE5)? event.clientY+document.body.scroll : evt.pageY;
currIDb.style.left=x+xoff+px;
currIDs.style.left=x+xoff+10+px;
currIDb.style.top=y+yoff+px;
currIDs.style.top=y+yoff+10+px;

用js做，呵呵，比较不错
Dreamwaver给你大把垃圾代码。
用我的吧：
层的拖动
<script>
//SZUDragDiv类的定义
function SZUDragDiv()
{
this.DragObj=null
this.Moving=false;
this.OffSetX=0
this.OffSetY=0
this.OldDocOnMove=document.onmousemove;
this.Grab=SZUDragDiv_Grab;
this.Move=SZUDragDiv_Move;
this.Drop=SZUDragDiv_Drop;
}
function SZUDragDiv_Grab(obj)
{
this.DragObj=obj
this.OffSetX=event.x-this.DragObj.style.pixelLeft
this.OffSetY=event.y-this.DragObj.style.pixel
this.Moving=true
document.onmousemove=this.Move
}
function SZUDragDiv_Move()
{
if(this.Moving==true)
{
this.OldDocOnMove
this.DragObj.style.pixelLeft=event.x-this.OffSetX
this.DragObj.style.pixel=event.y-this.OffSetY
}
}
function SZUDragDiv_Drop()
{
this.DragObj=null
this.Moving=false
document.onmousemove=this.OldDocOnMove
}
</script>
<script>
var myDrag=new SZUDragDiv(); //生成一个SZUDragDiv对象
</script>
在页面里
<div id=yourdiv style="position:absolute;" onmousedown="myDrag.Grab(this)" onmousemove="myDrag.Move()" onmouseup="myDrag.Drop()">
hello</div>
