js时间代码

一：

function date(){

//arguments JS自带的变量

this.length = arguments.length;

for(var i= 0; i < this.length; i ++){

this[i] = date.arguments[i];

}

function displaytime(){

var d = new Date();

var h = d.getHours();

var m = d.getMinutes();

var s = d.getSeconds();

//0-2 午夜 2-5 凌晨 5-9 早上 9-12 上午 12-14 中午 14-18 下午 18-24 晚上

var ampm = "上午";

if (h >= 0 && h < 2) ampm = "午夜";

if (h >= 2 && h < 5) ampm = "凌晨";

if (h >= 5 && h < 9) ampm = "早上";

if (h >= 9 && h < 12) ampm = "上午";

if (h >= 12 && h < 14) ampm = "中午";

if (h >= 14 && h < 18) ampm = "下午";

if (h >= 18) ampm = "晚上";

//12小时制

if (h >12) h -= 12;

//补0

if (m < 10) m = "0" + m;

//补0

if (s < 10) s = "0" + s;

var time = ampm + h + ":" + m + ":" + s;

//年月日和星期

var day = new date("星期日","星期一","星期二","星期三","星期四","星期五","星期六");

var ymd = d.getYear() + "年" + (d.getMonth() + 1) + "月" + d.getDate() + "日" + day[d.getDay()];

//取得显示位置

var tiemarea = document.getElementById("timearea");

timearea.innerHTML = ymd + " " + time;

setTimeout("displaytime()",1000);

}

</script>

</div>

二：

<SCRIPT>setInterval("jnkc.innerHTML=new Date().toLocaleString();",1000); </SCRIPT>

</div>
