如何实现弹出浮动层,让让后面的所有元素都禁用

http://groups.csdn.net/javascript/editsectioncard 点击那个卡片

看梅老大的思路，貌似是在body里插入一个width,height都是100%的层，把所有玩意儿都盖掉的样子让我感兴趣的是
MzLockWindow._hide("SELECT"); MzLockWindow._hide("OBJECT");}
我们都知道div是盖不住select这样地咚咚，so，梅老大就把他们都hide了，为了避免show的时候，把原来hide的误show出来，还加了个属性保存，呵呵那iframe里的select盖得住吗？没试过，问问

从梅老大的代码盗版而来，IE6.0,FF1.5下pass，对付着用吧<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
