效果如下：

function colok() {

var now = new Date(); //获取日期对象

var year = now.getYear(); //获取年

var month = now.getMonth(); //获取月份

var date = now.getDate(); //获取日

var day = now.getDay(); //获取星期

var hour = now.getHours(); //获取小时

var minu = now.getMinutes();//获取分

var sec = now.getSeconds(); //获取秒

var week;

month = month + 1;

if (month < 10){

month = "0" + month; //当月份小于10时，前补零

}

if (date < 10){

date = "0" + date; //当日期小于10时，前补零

}

if (hour < 10){

hour = "0" + hour; //当小时小于10时，前补零

}

if (minu < 10){

minu = "0" + minu; //当分钟小于10时，前补零

}

if (sec < 10){

sec = "0" + sec; //当秒小于10时，前补零

}

var arr_week = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五",

"星期六");

week = arr_week[day];

var time = "";

time = year + "年" + month + "月" + date + "日 " + week + " " + hour + ":"

+ minu + ":" + sec;//拼接显示的字符串

document.getElementById("time").innerHTML = "[" + time + "]";

var timer = setTimeout("colok()", 1000);//每隔1000毫秒自动执行函数

}

</script>
