鉴于网上找到的几个日期选择程序有些问题，遂着手重写一个程序，大部分还是借鉴前人的代码，添加了时间选择功能，隐藏会遮挡控件的标签select，object。
开始本想使用window.createPopup()来弹出日历的选择，这样就可以跨过任何标签。
不过做到中途发现用createPopup窗口实现理论上是行不通的：
一是因为不在窗体里单击任何地方都会关闭窗口，而当用下拉框选择年份时，很有可能会单击到窗体外的地方，当然这个可以自己写select来避免，但是比较麻烦；
二是窗体的宽度和高度只能在弹出时设置，而显然，在选择不同年月时，控件高度是要发生改变的。
鉴于上面的原因，还是决定采用普通的处理方法。

/**
*本日历选择控件由tiannet根据前人经验完善而得。大部分代码来自meizz的日历控件。
*tiannet添加了时间选择功能、select,object标签隐藏功能，还有其它小功能。
*使用方法：
* (1)只选择日期   <input type="text" name="date"   readOnly onClick="setDay(this);">
* (2)选择日期和小时  <input type="text" name="dateh"  readOnly onClick="setDayH(this);">
* (3)选择日期和小时及分钟 <input type="text" name="datehm" readOnly onClick="setDayHM(this);">
*设置参数的方法
* (1)设置日期分隔符    setDateSplit(strSplit);默认为"-"
* (2)设置日期与时间之间的分隔符  setDateTimeSplit(strSplit);默认为" "
* (3)设置时间分隔符    setTimeSplit(strSplit);默认为":"
* (4)设置(1),(2),(3)中的分隔符  setSplit(strDateSplit,strDateTimeSplit,strTimeSplit);
* (5)设置开始和结束年份    setYearPeriod(intDateBeg,intDateEnd)
*说明：
* 默认返回的日期时间格式如同：2005-02-02 08:08
