1.简单的显示年月日、星期、时间
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>当前系统时间</title>
<link rel="stylesheet" href="style.css" />
<script language="javascript" type="text/javascript">
window.onload = function(){
showTime();
}
function checkTime(i){ //补位处理
var i;
if(i<10){
i="0"+i;
}
return i;
}
function showTime(){
var now=new Date();
var year=now.getFullYear() ;
var month=now.getMonth()+1;
var day=now.getDate();
var h=now.getHours();
var m=now.getMinutes();
var s=now.getSeconds();
m=checkTime(m);
s=checkTime(s);
var d=now.getDay();
var weekday=new Array(7)
weekday[0]="星期日"
weekday[1]="星期一"
weekday[2]="星期二"
weekday[3]="星期三"
weekday[4]="星期四"
weekday[5]="星期五"
weekday[6]="星期六"
document.getElementById("show").innerHTML=""+year+"年"+month+"月"+day+"日 "+weekday[d]+h+":"+m+":"+s;
t=setTimeout(‘showTime()‘,500);
}
</script>
</head>
<body>
<div class="content1">
<div id="show">显示时间的位置</div>
</div>
</body>
</html>
2.制作倒计时
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>研究生考试时间</title>
<link rel="stylesheet" href="style.css" />
<script type="text/javascript">
window.onload = function(){
var timedate= new Date("2017,12,25"); //自定义结束时间
var now = new Date() ; //获取当前时间
var date = timedate.getTime() - now.getTime(); //得出的为毫秒
var time = Math.ceil(date/(1000*60*60*24)) ; //1000 * 60 * 60 * 24一天的秒数
if(time > 0 ){
document.getElementById(‘timeShow‘).innerHTML = time;
}else{
alert("时间已经到了");
}
}
</script>
</head>
<body>
<div class="content2">
<div class="txtshow">距离设置时间还有<span id="timeShow"></span>天</div>
</div>
</body>
</html>
