层移动兼容问题

Question

自己修改到下面这样了
在FF下可以拖动，但是只是在第一次的时候才可以
可以保存测试一下就知道了<script>
var isIE=(navigator.appVersion.toLowerCase().indexOf('msie')>=0);
var dragapproved=false;
if(document.all){
    document.onmouseup=new Function("dragapproved=false");
}
function Move(e){
    e=e||event;
    iex=e.clientX
    iey=e.clientY
    if(isIE==true){
        tempx=document.getElementById("moves").style.pixelLeft
        tempy=document.getElementById("moves").style.pixelTop
    }else{
        tempx=document.getElementById("moves").style.left;
        tempy=document.getElementById("moves").style.top;
    }
    dragapproved=true
    document.onmousemove=function(e){
        e=e||event;
        if (dragapproved==true){
            if(isIE==true){
                document.getElementById("moves").style.pixelLeft=tempx+e.clientX-iex
                document.getElementById("moves").style.pixelTop=tempy+e.clientY-iey
            }else{
                document.getElementById("moves").style.left = tempx+e.clientX-iex+"px";
                document.getElementById("moves").style.top = tempy+e.clientY-iey+"px";
            }
            return false
        }
    }
}
</script>
<div id="moves" style="position:absolute;">
    <div onMousedown="Move(event)">移动</div>
</div>
