在Jquery里格式化Date日期时间数据

function timeStamp2String(time){
var datetime = new Date();
datetime.setTime(time);
var year = datetime.getFullYear();
var month = datetime.getMonth() + 1 < 10 ? "0" + (datetime.getMonth() + 1) : datetime.getMonth() + 1;
var date = datetime.getDate() < 10 ? "0" + datetime.getDate() : datetime.getDate();
var hour = datetime.getHours()< 10 ? "0" + datetime.getHours() : datetime.getHours();
var minute = datetime.getMinutes()< 10 ? "0" + datetime.getMinutes() : datetime.getMinutes();
var second = datetime.getSeconds()< 10 ? "0" + datetime.getSeconds() : datetime.getSeconds();
return year + "-" + month + "-" + date+" "+hour+":"+minute+":"+second;
}
