请教，怎样给JSP时间控件设置初始时间？

laotiedeboke1 2015-08-07 06:34:48

请教，有以下JSP时间控件代码，这个代码没有初始值，怎样给其设置一个初始值？
需要是给第一个文本框赋初始值为当天的0点0分0秒；第二个文本框设置初始值为当天的23点59分59秒。

跪求高人指点!
本人新手，谢谢啦！
JSP时间控件部分代码如下：

<HTML>
<HEAD>
<TITLE>没有初始值的时间控件</TITLE>
<script language="javascript" type="text/javascript">
// 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)">

var bMoveable=true;
var strFrame;

document.writeln('<iframe id=endDateLayer frameborder=0 width=162 height=211 style="position: absolute; z-index: 9998; display: none"></iframe>');

strFrame+='INPUT.button{BORDER-RIGHT: #63A3E9 1px solid;BORDER-TOP: #63A3E9 1px solid;BORDER-LEFT: #63A3E9 1px solid;';

再说一遍，请教，这个代码没有初始值，怎样给其设置一个初始值？
需要是给第一个文本框赋初始值为当天的0点0分0秒；第二个文本框设置初始值为当天的23点59分59秒。
