For example, to add one day to the current date, use the following code: consttoday=newDate();consttomorrow=newDate()// Add 1 Daytomorrow.setDate(today.getDate()+1) To update an existing JavaScriptDateobject, you can do the following: constdate=newDate();date.setDate(date.getDate()+1...
If we are interested in adding that day to today, we can replace new Date(date) with new Date() in the above code, or we can pass the new Date() to the function directly. var tmpDate = new Date(); // Today console.log(addDaysToDate(tmpDate, 2)); // today + 2 Output: ...
Date.prototype.toISODate=function(){constyear=this.getFullYear();constmonth=String(this.getMonth()+1).padStart(2,'0');constday=String(this.getDate()).padStart(2,'0');return`${year}-${month}-${day}`;};// 使用示例constdate=newDate();constisoDate=date.toISODate();console.log(isoD...

Within the/build/folder, adate.jsfile has been created for each of the 150+ supported Cultures. Changing the Culture of the library is as easy as changing thedate.jsfile. <!-- Set the CultureInfo to de-DE (German/Deutsch) --> Before minification, the Datejs library is contained in ...
new Date(value); new Date(dateString); new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]); year:表示年份的整数值。0到99会被映射至1900年至1999年,其它值代表实际年份。 monthIndex:是从0开始计算的,这就意味着一月份为0,十二月份为11。 当Date...
The Date object in JavaScript returns the current day, date, and time (with time zone) on the device. In JavaScript, there are some situations where developers need to add hours to a Date object. The Date object offers a number of methods, including “setHours()”, “getTime()”, “...
