<!DOCTYPE html>

<head>
<meta charset="UTF-8">
<title>js_date</title>
</head>
<body>
<div id="newData"></div>
</body>
<script type="text/javascript">
function time(){
var mydate = new Date();
var year = mydate.getFullYear();
var mon = getMyMonth(mydate.getMonth());
var day = mydate.getDate();
var hour = mydate.getHours();
var min = mydate.getMinutes();
var sec = mydate.getSeconds();
document.getElementById("newData").innerHTML="如今的时间为："+year+"年"+mon+"月"+day+"日"+hour+"时"+min+"分"+sec+"秒";
}
window.setInterval(time,1000);
function getMyMonth(month){
switch(month){
case 0:
return 1;
break;
case 1:
return 2;
break;
case 2:
return 3;
break;
case 3:
return 4;
break;
case 4:
return 5;
break;
case 5:
return 6;
break;
case 6:
return 7;
break;
case 7:
return 8;
break;
case 8:
return 9;
break;
case 9:
return 10;
break;
case 10:
return 11;
break;
case 11:
return 12;
break;
}
}
</script>
</html>显示效果如下：
用setInterval()函数每秒执行一次。
