帮我看看吧，为什么一个可以达到拖动到我指定的地方的目的，而另外一个不行呢。只是Points设置不同而已，不明白




<script language="javascript">
var MOVEOBJ = null;
var MOVEFLAG = false;
function moveIt(obj){
document.onmousemove = move;
document.onmouseup = drop;

MOVEOBJ = obj;
CURRENTX = (event.clientX + document.body.scrollLeft);
CURRENTY = (event.clientY + document.body.scrollTop);
return true;
}

function move(){
if (MOVEOBJ == null) { return false; }
MOVEFLAG = true;
newX = (event.clientX + document.body.scrollLeft);
newY = (event.clientY + document.body.scrollTop);
newX = event.x;
newY = event.y;
var arr = new Array();
// alert(MOVEOBJ.Points.value);
arr = MOVEOBJ.Points.value.split(",");
MOVEOBJ.Points.value = arr[0] + ',' + arr[1] + ',' + newX + ',' + newY + ',' + arr[4] + ',' + arr[5];
event.returnValue = false;
return false;
}

function drop(){
if(MOVEFLAG) MOVEFLAG = false;
MOVEOBJ = null;
return true;
}
