// emu 现在把它改为IE/NS通用的了,但还没有进行充分测试。IE5,NS6.2下通过。
// walkingpoison说在ns7下面显示混乱,可惜emu的电脑丢了,没有办法在ns7下面继续调它了,有兴趣的朋友继续努力……

//----------------------------------------------------------------------------
//  这是梅花雨做的一个日历 Javascript 页面脚本控件,适用于微软的 IE (5.0以上)浏览器
//  主调用函数是 setday(this,[object])和setday(this),[object]是控件输出的控件名,举两个例子:
//  一、<input name=txt><input type=button value=setday onclick="setday(this,document.all.txt)">
//  二、<input onfocus="setday(this)">
//  若有什么不足的地方,或者您有更好的建议,请与我联系:mail: meizz@hzcnc.com
//  本日历的年份限制是(1000 - 9999)
//  按ESC键关闭该控件
//  在年和月的显示地方点击时会分别出年与月的下拉框
//  控件外任意点击一点即可关闭该控件
/* 以下为walkingpoison的修改说明
walkingpoison联系方式:wayx@kali.com.cn

Ver        2.0
修改日期:2002-12-13
修改内容:
1.*全新修改使用iframe作为日历的载体,不再被select和flash等控件挡住。
2.修正了移植到iframe后移动日历控件的问题。

Ver        1.5
修改日期:2002-12-4
修改内容:
1.选中的日期显示为凹下去的样式
2.修改了关闭层的方法,使得失去焦点的时候能够关闭日历。
3.修改按键处理,使得Tab切换焦点的时候可以关闭控件
4.*可以自定义日历是否可以拖动

Ver 1.4
修改日期:2002-12-3
修改内容:
1.修正选中年/月份下拉框后按Esc键导致年/月份不显示的问题
2.修正使用下拉框选择月份造成的日期错误(字符串转化为数字的问题)
3.*外观样式的改进,使得控件从丑小鸭变成了美丽的天鹅,从灰姑娘变成了高贵的公主,从……(读者可以自己进行恰当的比喻)
4.再次增大年/月份的点击空间,并对下拉框的位置稍作调整

注:*号表示比较关键的改动

说明:
1.受到iframe的限制,如果拖动出日历窗口,则日历会停止移动。
