推荐兼容 IE、 FireFox 的 javascript 日历控件

一、简介与声明
此日历控件是 CSDN 网友 KimSoft 的作品：http://blog.csdn.net/kimsoft/archive/2006/05/24/753225.aspx 。界面清爽，纯脚本运行，实现了日期的回显功能，最重要的是兼容 FireFox 。
为了适应更多需求，我针对该控件作了以下修改：
1、返回日期的输出格式，我改成了由用户以参数形式指定 Style
2、关于 IE 中 <select> 下拉框的处理，不调用隐藏，而是用<iframe>直接覆盖
3、不使用 //this.panel.style.visibility = "hidden"; 因为它在 FireFox 中会掩盖之前出现过地方下面的链接文字，而是改用 this.panel.style.display = "none";
4、新增失去焦点后，整个 WebCalendar 即隐藏

三、调用方法
1、引用 WebCalendar.js
<script src="js/WebCalendar.js" type="text/javascript"></script>
2、编写触发的脚本事件
this.Txt_Date.Attributes["onclick"] = "SelectDate(this,'yyyy-MM-dd')";
<input name="Txt_Date" type="text" maxlength="10" id="Txt_Date" onclick="SelectDate(this,'yyyy-MM-dd')" />

三、调用方法
1、引用 WebCalendar.js
<script src="js/WebCalendar.js" type="text/javascript"></script>
2、编写触发的脚本事件
this.Txt_Date.Attributes["onclick"] = "SelectDate(this,'yyyy-MM-dd')";
<input name="Txt_Date" type="text" maxlength="10" id="Txt_Date" onclick="SelectDate(this,'yyyy-MM-dd')" />
