Question

**<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"＆GT; **

在上面的dtd中， calender 程序在 IE 8，Chrome，safari，opera 中工作正常但是在Firefox中它会产生问题将所有值显示为1.

我在下面给出的日历程序脚本请检查并帮助我

该脚本不适用于该doctype。它生成HTML代码，而不是XHTML代码。

此外，该脚本使用eval来查找元素而不是document.getElementById，这些元素仅适用于尝试模拟它的IE和浏览器。 eval函数有很少的用途，但这并不是很好用。如果您只有您所描述的那个问题，我会感到惊讶。

IE浏览器中的Javascript与Firefox错误
