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?
当前回答
@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
};

有些日期=新日期(); =某物。 游戏机。log (dateFormated);
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,"")
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
似乎mootools提供了Date().format(): https://mootools.net/more/docs/1.6.0/Types/Date
但我不确定是否值得只针对这个特定的任务。
