JS 得到日期時間。年月日時分秒

<script  type="text/javascript">
function curDateTime() {
var d = new Date();
var year = d.getFullYear();
var month = d.getMonth() + 1;
var date = d.getDate();
var day = d.getDay();
var Hours=d.getHours(); //获取当前小时数(0-23)
var Minutes=d.getMinutes(); //获取当前分钟数(0-59)
var Seconds=d.getSeconds(); //获取当前秒数(0-59)
var curDateTime = year;
if (month > 9)
curDateTime = curDateTime + month;
else
curDateTime = curDateTime + "0" + month;
if (date > 9)
curDateTime = curDateTime + date;
else
curDateTime = curDateTime + "0" + date;
if (Hours > 9)
curDateTime = curDateTime + Hours;
else
curDateTime = curDateTime + "0" + Hours;
if (Minutes > 9)
curDateTime = curDateTime + Minutes;
else
curDateTime = curDateTime + "0" + Minutes;
if (Seconds > 9)
curDateTime = curDateTime + Seconds;
else
curDateTime = curDateTime + "0" + Seconds;
document.getElementById("NumberNo").value=curDateTime;
}
curDateTime();
