关于寒羽风的WebCalendar.js不能选当天之后的时间

问题描述

有谁用过这个日历控件的，这个控件不能选择当日之后的日期，只能选择之前的日子，看了半天看不懂，我贴上代码 <!-- var cal; var isFocus=false; //是否为焦点 //以上为  寒羽枫 2006-06-25 添加的变量 //选择日期 → 由 寒羽枫 2006-06-25 添加 function SelectDate(obj,strFormat) {     var date = new Date();

解决方案

发给你了 里面我写了样例程序，当然，里面还可以传很多参数控制。收到回复。
解决方案二：
引用这个空间不怎么样吧。我发给你一个好用的。
解决方案三：
哈哈 好长啊。这个空间不怎么样吧。我发给你一个好用的。
