    var date = dateObj.getDate();//日
    var day = dateObj.getDay();

    var week = weeks[day];//根据day值，获取星期数组中的星期数。
    var hours = dateObj.getHours();//小时

    var seconds = dateObj.getSeconds();//秒

    if(month<10){
        month = "0"+month;
    }
    if(date<10){
        date = "0"+date;
    }
    if(hours<10){
        hours = "0"+hours;
    }
    if(minutes<10){
        minutes = "0"+minutes;
    }
    if(seconds<10){
        seconds = "0"+seconds;
    }

    var newDate = year+"年"+month+"月"+date+"日"+hours+":"+minutes+":"+seconds+"&nbsp &nbsp"+week;
    document.getElementById("date1").innerHTML = "时间显示：" + newDate;//在div中写入时间
    setTimeout('getTime()', 500);//每隔500ms执行一次getTime()
}
</script>

<body onLoad="getTime()">
    <div id="date1">时间</div>
</body>
