我不喜欢修改本机对象，而且我认为乘法比填充接受的解决方案的字符串更清楚。

函数yyyymmdd(dateIn) { var yyyy = dateIn.getFullYear(); var mm = dateIn.getMonth() + 1;// getMonth()是从零开始的 var dd = dateIn.getDate(); 返回String(10000 * yyyy + 100 * mm + dd);// mm和dd的前导零 ｝ var today = new Date(); console.log(名称(今天));

// utc / gmt 0 文档。write('UTC/GMT 0: ' + (new Date()). toisostring()。片(0,19)。替换(/ [^ 0 - 9]/ g, " "));/ / 20150812013509 //客户端本地时间 文档。write('<br/>本地时间:' + (new Date(Date.now()-(new Date()). gettimezoneoffset () * 60000)). toisostring()。片(0,19)。替换(/ [^ 0 - 9]/ g, " "));/ / 20150812113509

纯JS (ES5)解决方案，没有任何可能的日期跳转问题，由date . toisostring()打印UTC:

var now = new Date();
var todayUTC = new Date(Date.UTC(now.getFullYear(), now.getMonth(), now.getDate()));
return todayUTC.toISOString().slice(0, 10).replace(/-/g, '');

这是为了回应@weberste对@Pierre Guilbert的回答的评论。

Try this:

函数showdate () {

var a = new Date();
var b = a.getFullYear();
var c = a.getMonth();
(++c < 10)? c = "0" + c : c;
var d = a.getDate();
(d < 10)? d = "0" + d : d;
var final = b + "-" + c + "-" + d; 

return final;


} 

document.getElementById("todays_date").innerHTML = showdate();

var dateDisplay = new Date( 2016-11-09 05:27:00 UTC );
dateDisplay = dateDisplay.toString()
var arr = (dateDisplay.split(' '))
var date_String =  arr[0]+','+arr[1]+' '+arr[2]+' '+arr[3]+','+arr[4]

这将显示像Wed,Nov 09 2016,10:57:00这样的字符串

一个衬线(2022)，带正确的时区偏移

var dateDisplay = new Date(Date.now() - (new Date().getTimezoneOffset() * 1000 * 60)).toJSON().slice(0, 10).replaceAll("-", "");

// YearMonthDay var dateDisplay = new Date(Date.now() - (new Date().getTimezoneOffset() * 1000 * 60)).toJSON().slice(0, 10).replaceAll("-", ""); console.log("YearMonthDay"); console.log(dateDisplay); // Year-Month-Day var dateDisplay = new Date(Date.now() - (new Date().getTimezoneOffset() * 1000 * 60)).toJSON().slice(0, 10); console.log("Year-Month-Day"); console.log(dateDisplay); // Year-Month-Day Hour:Minute:Second var dateDisplay = new Date(Date.now() - (new Date().getTimezoneOffset() * 1000 * 60)).toJSON().slice(0, 19).replace("T", " "); console.log("Year-Month-Day Hour:Minute:Second"); console.log(dateDisplay); // Year-Month-Day Hour-Minute-Second var dateDisplay = new Date(Date.now() - (new Date().getTimezoneOffset() * 1000 * 60)).toJSON().slice(0, 19).replace("T", " ").replaceAll(":", "-"); console.log("Year-Month-Day Hour-Minute-Second"); console.log(dateDisplay); // ISO-8601 standard: YYYY-MM-DDTHH:mm:ss.sssZ var dateDisplay = new Date(Date.now() - (new Date().getTimezoneOffset() * 1000 * 60)).toJSON(); console.log("ISO-8601 standard: YYYY-MM-DDTHH:mm:ss.sssZ"); console.log(dateDisplay);
