本文实例讲述了JS实现漂亮的时间选择框效果。分享给大家供大家参考，具体如下：
HTML代码部分：
<html><script language=javascript src="dataone.js"></script><table align="center"><tr><td><body>(1)只选择日期 <input type="text" name="date" readOnly onClick="setDay(this);"><br/> (2)选择日期和小时 <input type="text" name="dateh" readOnly onClick="setDayH(this);"><br/> (3)选择日期和小时及分钟 <input type="text" name="datehm" readOnly onClick="setDayHM(this);"> </body></td></tr></table></html>
dataone.js代码：
/***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;";
