本文实例为大家分享了JavaScript自定义日历签到功能的具体代码，供大家参考，具体内容如下
先看下效果图
红色块为已签到的日期，样式可以随意更改，清晰明了，话不多说上代码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>My JSP 'index.jsp' starting page
js文件：
