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*///------------------ 样式定义 ---------------------------////功能按钮同样样式var s_tiannet_turn_base = "height:16px;font-size:9pt;color:white;border:0 solid #CCCCCC;cursor:hand;background-color:#2650A6;";//翻年、月等的按钮var s_tiannet_turn = "width:28px;" + s_tiannet_turn_base;//关闭、清空等按钮样式var s_tiannet_turn2 = "width:22px;" + s_tiannet_turn_base;//年选择下拉框var s_tiannet_select = "width:64px;display:none;";//月、时、分选择下拉框var s_tiannet_select2 = "width:46px;display:none;";//日期选择控件体的样式var s_tiannet_body = "width:150;background-color:#2650A6;display:none;z-index:9998;position:absolute;" + "border-left:1 solid #CCCCCC;border-top:1 solid #CCCCCC;border-right:1 solid #999999;border-bottom:1 solid #999999;";//显示日的td的样式var s_tiannet_day = "width:21px;height:20px;background-color:#D8F0FC;font-size:10pt;";//字体样式var s_tiannet_font = "color:#FFCC00;font-size:9pt;cursor:hand;";//链接的样式var s_tiannet_link = "text-decoration:none;font-size:9pt;color:#2650A6;";//横线var s_tiannet_line = "border-bottom:1 solid #6699CC";//------------------ 变量定义 ---------------------------//var tiannetYearSt = 1950;
