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);

const date = new Date()

console.log(date.toISOString().split('T')[0]) // 2022-12-27

以下是对https://stackoverflow.com/users/318563/o-o的回答的一点改进

Date.prototype.ddmmyyyy = function(delimiter) {
    var yyyy = this.getFullYear().toString();
    var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
    var dd  = this.getDate().toString();
    return (dd[1]?dd:"0"+dd[0]) + delimiter + (mm[1]?mm:"0"+mm[0]) + delimiter +yyyy  ; // padding
};

希望对大家有所帮助!

回答另一个简单性和可读性的问题。 此外，不鼓励使用新方法编辑现有的预定义类成员:

function getDateInYYYYMMDD() {
    let currentDate = new Date();

    // year
    let yyyy = '' + currentDate.getFullYear();

    // month
    let mm = ('0' + (currentDate.getMonth() + 1));  // prepend 0 // +1 is because Jan is 0
    mm = mm.substr(mm.length - 2);                  // take last 2 chars

    // day
    let dd = ('0' + currentDate.getDate());         // prepend 0
    dd = dd.substr(dd.length - 2);                  // take last 2 chars

    return yyyy + "" + mm + "" + dd;
}

var currentDateYYYYMMDD = getDateInYYYYMMDD();
console.log('currentDateYYYYMMDD: ' + currentDateYYYYMMDD);

yyyymmdd=x=>（f=x=>（x<10&&'0'）+x，x.getFullYear（）+f（x.getMonth（）+1）+f（x.getDate（）））; 警报（年年月日（新日期））;

这段代码修复了Pierre Guilbert的答案:

(10000年后依然有效)

YYYYMMDD=new Date().toISOString().slice(0,new Date().toISOString().indexOf("T")).replace(/-/g,"")
