这篇文章主要介绍了js实现精确到秒的日期选择器,以完整实例形式分析了JavaScript日期选择器的实现步骤与相关技巧,涉及JavaScript针对时间与日期的相关运算,需要的朋友可以参考下

本文实例讲述了js实现精确到秒的日期选择器。分享给大家供大家参考，具体如下：

<script>

// 主调用函数是 setday(this,[object])和setday(this)，[object]是控件输出的控件名，举两个例子：

// 一、<input name=txt><input type=button value=setday onclick="setday(this,document.all.txt)">

// 二、<input onfocus="setday(this)">
