整理之前写的一个登录页面，包含js获取时间、节假日、节气，根据一天中各个时间段显示问候语，登陆背景也会根据节假日和24节气更换背景，为你的项目添加更多可能
一、一天中根据时间变换问候语
html
<div class="welcomeMsg"><span id="welcomeMsg"></span><span id="timeClock"></span></div>js
welcomeMsg();
tick();
function welcomeMsg(){
now = new Date(),hour = now.getHours();
if(hour == 23 || hour < 6){$("#welcomeMsg").html("别熬夜了，该睡觉了！");}
else if(hour < 9){$("#welcomeMsg").html("早上好，开始美好的一天！");}
else if(hour < 12){$("#welcomeMsg").html("上午好，加油工作！");}
else if(hour < 13){$("#welcomeMsg").html("中午好，吃好休息好！");}
else if(hour < 18){$("#welcomeMsg").html("下午好，继续努力工作！");}
else if(hour < 23){$("#welcomeMsg").html("晚上好，放松心情！");}
}
//选择当前时间
function showLocale(objD){
var str,colorhead,colorfoot;
var yy = objD.getYear();
if(yy<1900) yy = yy+1900;
var MM = objD.getMonth()+1;
if(MM<10) MM = '0' + MM;
var dd = objD.getDate();
if(dd<10) dd = '0' + dd;
var hh = objD.getHours();
if(hh<10) hh = '0' + hh;
var mm = objD.getMinutes();
if(mm<10) mm = '0' + mm;
var ss = objD.getSeconds();
if(ss<10) ss = '0' + ss;
var ww = objD.getDay();
if ( ww==0 );
if ( ww > 0 && ww < 6 ) colorhead="<font class=\"white\">";
if ( ww==6 ); colorhead1="<font class=\"nowtime\">";
if (ww==0) ww="周日";
if (ww==1) ww="周一";
if (ww==2) ww="周二";
if (ww==3) ww="周三";
if (ww==4) ww="周四";
if (ww==5) ww="周五";
if (ww==6) ww="周六";
colorfoot="</font>"
str = colorhead1+ hh + ":" + mm + ":" + ss +colorhead1 + colorfoot;
return(str);
}
function tick()
{
var today;
today = new Date();
//当前日期时间
document.getElementById("timeClock").innerHTML = showLocale(today);
window.setTimeout("tick()", 1000);
}效果如下：
二、根据节假日、节气变化背景
html
<div class="wrap"></div>css
.wrap{
position:fixed;
top:0;
right:0;
bottom:0;
left:0;
background: #000 left center no-repeat;
background-attachment: fixed;
background-size: cover;
}js
var localpath = '../images/bg/';
changeBackground(localpath);
function changeBackground(localpath){
var festivals={

};
now = new Date(),hour = now.getHours();
var background = festivals[(now.getMonth()+1)+'/'+now.getDate()]; //节日
var background1 = festivals[showCal()]; //农历节日
var background2 = festivals[getjq(now.getFullYear(),now.getMonth()+1,now.getDate())]; //节气
if(background == undefined){
if(background1 == undefined){
if(background2 == undefined){
//非节假日、非节气日的早中晚背景
if(hour >=7 && hour <=11){
background = localpath+'morning.jpg';
}else if(hour >=12 && hour <=17){
background = localpath+'afternoon.jpg';
}else {
background = localpath+'evening.jpg';
}
}else{
background = background2;
}
}else{
background = background1;
}
}
$('.wrap').css('background-image', 'url('+background+')');
}下面是获取农历和节气的方法
