一个简单的JS日期挂历脚本
分享一个JS脚本做的日期挂历，在需要的时候可以引入你的程序。
如需单独引入这个脚本，请将它保存在一个文件中然后引入它：如这样
<script type="text/javascript" src="${pageContext.request.contextPath}/jsFile/Birthday.js" ></script>
若不需要引入，而将它作为内置与html的一部分，则在需要调用的地方调用该事件；
<input id="username" type="text" "new Calendar().show(this);" readonly="readonly" >
//调用实例
// onclick="new Calendar().show(this);" readonly="readonly"
