本文实例为大家分享了java编写全年考勤日历的具体代码，供大家参考，具体内容如下

JAVA代码：

 }
 public String dateCellClick(){
 
 return SUCCESS;
 }
}

action配置：

HTML代码：

<%@ page language="java" contentType="text/html; charset=utf-8"
 pageEncoding="utf-8"%>
<%
 String path = request.getContextPath();
 String basePath = request.getScheme() + "://"
  + request.getServerName() + ":" + request.getServerPort()
  + path;
%>
<%@taglib prefix="s" uri="/struts-tags"%>

 
  .disabledTd{
  background-color:gray;
  }
  .weekendTd{
  background-color:yellow;
  }
  .holidayTd{
  background-color:green;
  }
  .generalTd{
  background-color:white;
  }
  #calTbl{
  font-family: verdana,arial,sans-serif;
  font-size:13px;
  color:#333333;
  border-width: 1px;
  border-color: #a9c6c9;
  border-collapse: collapse;
  }
  #calTbl th{
  border-width: 1px;
  padding: 4px;
  border-style: solid;
  border-color: #a9c6c9;
  background-color:olive;
  }
  #calTbl td {
  border-width: 1px;
  padding: 4px;
  border-style: solid;
  border-color: #a9c6c9;
  }
  .rowHeader{
  background-color:olive;
  }
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
    
 
 
  
  
 

效果如下
