绝对完美！！变量空间递归终于研究成功了哈哈~~~~~~

楼主你是指的这个吗？
http://www.lostinet.com/test.asp

哎，，我也知道IE5会死的了。。已经麻木了。就是这个URL的原码
http://www.lostinet.com/public/VariablesScopeRecursion.html------------------
首先是函数定义的递归：
//construct new Licence for this scope
eval(PopupLicence+"");
//re construct InnerPopup for recursion
eval(InnerPopup+"");然后这里调用的时候，InnerPopup已经是内部的第N层了。
//variables scope recursion
InnerPopup(node,Command,GetElementScrollX(td)+td.offsetWidth,GetElementScrollY(td));
上面就是空间的递归点。（哈哈，，空间析构的地方很模糊，也是IE5死的原因）

楼主这么高兴，可惜我学艺不精看不懂，只能恭喜楼主了

效果还不错，windows的级联菜单。

原来也可以用这种方法做树阿！那我给公司做的那个商品列表就有头目了！动态成生XML到HTML文档里。我倒是第一次看到！good!!!!

2: mybios(俊俊哥哥)我用XML只是因为我有那堆XML，不想弄其他数据而已。
做成菜单也是因为想不到有什么好做

点左键啊：function RetractPopupLicence()
{
new PopupLicence().Retract();
}
document.attachEvent("onclick",RetractPopupLicence);

调试易

绝对完美！！变量空间递归终于研究成功了哈哈~~~~~~
