<!--  
//-------------------------------------------------------------------------------

// 这是一个日历 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,\[object\])，\[object\]是控件输出的控件名，举两个具体调用的例子：  
// 一、<input name=txt><input type=button value=setday οnclick="setday(this,document.all.txt)">  
// 二、<input οnfοcus="setday(this)">  
// 本日历的年份限制是（1000 - 9999）
