在JQuery中如何获取当前时间？

////发表时间(now)
function p(s) {
return s < 10 ? '0' + s : s;
}
var myDate = new Date();
//获取当前年
var year = myDate.getFullYear();
//获取当前月
var month = myDate.getMonth() + 1;
//获取当前日
var date = myDate.getDate();
var h = myDate.getHours(); //获取当前小时数(0-23)
var m = myDate.getMinutes(); //获取当前分钟数(0-59)
var s = myDate.getSeconds();

var now = year + '-' + p(month) + "-" + p(date) + " " + p(h) + ':' + p(m) + ":" + p(s);
