JS实现漂亮的时间选择框效果

Posted in Javascript onAugust 20, 2016

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
