没有细看你的代码, 不过你的eval显然不是最好的代码:
eval("var mdata = document.all.div" + obj.substr(6,1) + ".style.display");
==>
var mdata = document.getElementById("div"+ obj.substr(6, 1)).style.display;//若是不考虑浏览器兼容性的话你也可以用:
var mdata = document.all("div"+ obj.substr(6,1)).style.display;
eval("var mdata = document.all.div" + obj.substr(6,1) + ".style.display");
==>
var mdata = document.getElementById("div"+ obj.substr(6, 1)).style.display;//若是不考虑浏览器兼容性的话你也可以用:
var mdata = document.all("div"+ obj.substr(6,1)).style.display;
getElementById(nnn)
nnn="xxx"
或者是
a="x" nnn="xx"+a很多人也许对request.form("xxx")也是有这样的困惑的其实道理是一样的用request.form(nnn)代替也是一样的，做程序一定不要想得太死了
