从CSDN上下了个div拖动的代码，但在FF下不能运作，请大家帮忙改改

介绍一个:
http://www.cnblogs.com/cloudgamer/archive/2008/09/15/1290954.html

N多错误,建议楼主放弃吧.
ff3不支持的东东
   divClone.childNodes[1].setAttribute("onmousemove", function(){startMove(this,event)});
   divClone.childNodes[1].setAttribute("onmouseup", function(){endMove()});   var cDiv = document.createElement;
   var backDiv = cDiv("div");以及event对象的获取,都是不正确的,呵呵.
本来想帮你改改的,错误地方太多了.
今天事太多了.

主要是不兼容的写法．修改量太大了．
divClone.childNodes[1].setAttribute("onmousemove", function(){startMove(this,event)});
＝＞
divClone.childNodes[1].onmousemove = function(event){ startMove(this, event);};var cDiv = document.createElement;
var backDiv = cDiv("div");
＝＞
var backDiv = document.createElement("div");js要么写通用的写法，要么就要注意兼容不同的浏览器．
这两种写法，至少在ie ,ff上是有效的．

改了一下，FF下能显示，但移动不能。setcapture怎么改？<html>

topDiv.setAttribute("onmousedown", function(){setMove(this,event)});
之类的改成
topDiv.addEventLisenter("onmousedown", function(){setMove(this,event)});
window.setCapture(Event.MOUSEMOVE|Event.MOUSEUP);
改成
window.captureEvents(Event.MOUSEMOVE|Event.MOUSEUP);对应的其他
releaseCapture => releaseEvents
detachEvent => removeEventListener
