How do I get the current date in JavaScript?
如何在JavaScript中获取当前日期？
使用new Date()生成一个包含当前日期和时间的新Date对象。
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10) {
dd = '0'+dd
}
if(mm<10) {
mm = '0'+mm
}
today = mm + '/' + dd + '/' + yyyy;
document.write(today);
var utc = new Date().toJSON().slice(0,10).replace(/-/g,'/');
document.write(utc);UPDATED! , Scroll Down
If you want something simple pretty to the end user ... Also, fixed a small suffix issue in the first version below. Now properly returns suffix. Also, fixed a small suffix issue in the first version below. Now properly returns suffix.
var objToday = new Date(),
weekday = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'),
dayOfWeek = weekday[objToday.getDay()],
domEnder = function() { var a = objToday; if (/1/.test(parseInt((a + "").charAt(0)))) return "th"; a = parseInt((a + "").charAt(1)); return 1 == a ? "st" : 2 == a ? "nd" : 3 == a ? "rd" : "th" }(),
dayOfMonth = today + ( objToday.getDate() < 10) ? '0' + objToday.getDate() + domEnder : objToday.getDate() + domEnder,
months = new Array('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'),
curMonth = months[objToday.getMonth()],
curYear = objToday.getFullYear(),
curHour = objToday.getHours() > 12 ? objToday.getHours() - 12 : (objToday.getHours() < 10 ? "0" + objToday.getHours() : objToday.getHours()),
curMinute = objToday.getMinutes() < 10 ? "0" + objToday.getMinutes() : objToday.getMinutes(),
curSeconds = objToday.getSeconds() < 10 ? "0" + objToday.getSeconds() : objToday.getSeconds(),
curMeridiem = objToday.getHours() > 12 ? "PM" : "AM";
var today = curHour + ":" + curMinute + "." + curSeconds + curMeridiem + " " + dayOfWeek + " " + dayOfMonth + " of " + curMonth + ", " + curYear;
document.getElementsByTagName('h1')[0].textContent = today;<h1></h1>
