JS实现漂亮的时间选择框效果
更新时间：2016年08月20日 11:46:12 作者：xiangqian0505
这篇文章主要介绍了JS实现漂亮的时间选择框效果,结合实例形式分析了javascript时间选择框插件的实现与使用方法,需要的朋友可以参考下
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
