js日期选择控件

网上有许多js写的时间选择控件，但大都不能在aspx中使用（只能在html中用）
好不容易找到一个可以用的，不过界面难看了 代码如下：


dateTimePicker.js代码如下：

//   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)">

在head中包含
<script language="JavaScript" type="text/javascript" src="dateTimePicker.js"></script>

在输入框
<input id="t_startTime" type="text" class="gray_18" value="" size="15" runat="server" onclick="setday(this)">

编码问题：
最佳方法是把js的编码换成utf-8，而不是把aspx的编码换成gb2312
在vs中打开该js文件，选择 文件－－另存为  在弹出的对话框中选高级－－编码 选择utf-8编码
