因为要做一个日历控件，遇到国家法定节假日,怎么实现此功能呢？其实实现代码很简单的。下面我给大家分享js判断节假日实例代码，需要的朋友参考下吧
效果展示：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<script src="jquery.min.js" type="text/javascript"></script>
<script src="date.js" type="text/javascript"></script>
</head>

<body>
<h3>填写时间算算我们能上几天班？！</h3>
<p id="p1">
开始时间：<input id="startDate" type="text" value="2018-02-01"></input>
截止日期：<input id="endDate" type="text" value="2018-02-28"></input>

ps：下面在给大家分享一段代码基于js判断所有节假日，具体代码如下所示：
// JavaScript Document
calendar = new Date();
month = calendar.getMonth();
date = calendar.getDate();
if ((month == 0) && (date == 1)) document.write("元旦");
if ((month == 1) && (date ==13 )) document.write("除夕");
if ((month == 1) && (date ==14 )) document.write("春节/情人节");
if ((month == 2) && (date == 1)) document.write("国际海豹日");
if ((month == 2) && (date == 8)) document.write("国际劳动妇女节/中国保护母亲河日");
if ((month == 2) && (date == 12)) document.write("植树节");
if ((month == 3) && (date == 1)) document.write("愚人节");
if ((month == 3) && (date == 5)) document.write("清明节");
if ((month == 4) && (date == 1)) document.write("国际劳动节");
if ((month == 4) && (date == 9)) document.write("母亲节");
if ((month == 5) && (date == 1)) document.write("国际儿童节");
if ((month == 5) && (date == 26)) document.write("国际禁毒日");
if ((month == 7) && (date == 1)) document.write("建军节");
if ((month == 7) && (date == 15)) document.write("日本无条件投降日/世纪婚纱日");
if ((month == 7) && (date == 16)) document.write("七夕情人节");
if ((month == 9) && (date == 20)) document.write("世界厨师日");
if ((month == 9) && (date == 22)) document.write("世界传统医药日");
if ((month == 9) && (date == 24)) document.write("联合国日/世界发展信息日");
if ((month == 9) && (date == 25)) document.write("世界骨质疏松日/抗美援朝纪念日/环卫工人节");
if ((month == 9) && (date == 31)) document.write("世界勤俭日/中国男性健康日");
if ((month == 11) && (date == 24)) document.write("平安夜");
if ((month == 11) && (date == 25)) document.write("圣诞节");
上面是我整理给大家的，希望今后会对大家有帮助。
