我试图使用JS将日期对象转换为YYYYMMDD格式的字符串。有没有比连接Date.getYear()， Date.getMonth()和Date.getDay()更简单的方法?

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);

原生Javascript:
new Date().toLocaleString('zu-ZA').slice(0,10).replace(/-/g,'');
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））;
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
@o-o解对我没用。 我的解决方案如下:
Date.prototype.yyyymmdd = function() {
var mm = this.getMonth() + 1; // getMonth() is zero-based
var dd = this.getDate();
var ret = [this.getFullYear(), (mm<10)?'0':'', mm, (dd<10)?'0':'', dd].join('');
return ret; // padding
};
我试图写一个简单的库操作JavaScript日期对象。你可以试试这个。
var dateString = timeSolver.getString(date, "YYYYMMDD")
