如果DIV在ID为area的div中，即可拖拽。我在Drag函数里做了对父div的判断。

var _x = e.offsetX || e.layerX
var _y = e.offsetY || e.layerY
o.style.filter = 'Alpha(opacity=70)'
o.style.opacity = '0.7'
document.onmousemove = function(e){
var e = window.event || e
o.style.left = e.clientX - _x + 'px'
o.style.top = e.clientY - _y + 'px'
o.style.cursor="move"
}
document.onmouseup = function(e){
document.onmousemove = null
o.style.filter = o.style.opacity = ''
o.style.cursor="default"
}
}

<body>
<div id='area'>
<div onmousedown="Drag(this, event)" style="position:absoluteborder:1px solid redbackground:pinkwidth:400pxheight:300px"></div>

<div onmousedown="Drag(this, event)" style="position:absoluteleft:500pxborder:1px solid redbackground:pinkwidth:400pxheight:300px"></div>

前两天看错了，没能理解你的意思。今天碰巧又逛进来了所以修改了下，看符合你的要求不。
希望更简洁的代码？
那么使用eq（index）方法吧。一行代码解决你的问题。
//
//x:要在A中查找，x=1，在B中找：x=2...
//y：要找num1 y=1,找num2 y=2，.....
//
function getObj(x,y)
{
return $("body>div").eq(x-1).find("div").eq(y-1)
}
使用方法：
$(function())
将查找出D中的num3并显示其text
希望能帮助到你。
如果对您有帮助，请记得采纳为满意答案，谢谢！祝您生活愉快！
