1. target 为空或者不是对象

2. code:
function initDrag(e)
{
var DragHandle = nn6? e.target:event.srcElement; //这句错误

var topElement ="HTML";
while(DragHandle.tarName!= topElement &&DragHandle.className!="dragAble")
{
DragHandle =nn6?DragHandle.parentNode:DragHandle.parentElement;
}
if(DragHandle.className =="dragAble")
{
isdrag = true;
DragObj =DragHandle ;
nTY = parseInt(DragObj.style.top +0);
y = nn6 ? e.clientY : event.clientY;
nTX = parseInt(DragObj.style.left +0);
x = nn6 ? e.clientX: event.clientX;
document.onmousemove =moveMouse;
return false;
}



}

document.onmousedown=initDrag;
document.onmouseup=new Function("isdrag=false");

设个断点看看target是什么不就知道了么？

[JeffrySun]

var DragHandle == nn6? e.target:event.srcElement;

少了个=，变成赋值了， 估计是手误

不知道实际程序里是不是也这么写的
