function addOneDayToDate() { var currentDate = new Date(); currentDate.setDate(currentDate.getDate() + 1); return currentDate; } 在这个例子中,我们创建了一个名称为addOneDayToDate()的函数,该函数返回当前日期加上1天的日期。 总结 在JavaScript中,要添加1天日期,我们可以使用内置的Date对象和set...
Date.prototype.getDaysDiff=function(otherDate){constoneDay=24*60*60*1000;// 一天的毫秒数constdiffInTime=Math.abs(this-otherDate);constdiffInDays=Math.round(diffInTime/oneDay);returndiffInDays;};// 使用示例constdate1=newDate('2022-01-01');constdate2=newDate('2022-01-10');constdaysDiff=...

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...
Date.today().addDays(1)// Add one day (+1).Date.today().addMonths(-3)// Subtract three months (-3).Date.today().add(1).day()// Add one (+1) day. Supports all date parts (year, month, day, hour, minute, second, millisecond, and weeks)Date.today().add(-3).months()//...

在上述代码中,addOneMinute函数接受一个时间对象作为参数,并返回增加一分钟后的时间对象。我们通过创建一个新的时间对象,并使用setMinutes方法进行增加操作。最后返回新的时间对象。 类图 下面是一个表示时间对象的类图示例: Date- year: number- month: number- day: number- hour: number- minute: number- second...
Date.today().addDays(1)// Add one day (+1).Date.today().addMonths(-3)// Subtract three months (-3).Date.today().add(1).day()// Add one (+1) day. Supports all date parts (year, month, day, hour, minute, second, millisecond, and weeks)Date.today().add(-3).months()//...
newDate();newDate(value);newDate(dateString);newDate(year,monthIndex[,day[,hours[,minutes[,seconds[,milliseconds]]]); 1. 2. 3. 4. 注意, 创建一个新Date对象的唯一方法是通过 new 操作符,例如:let now = new Date(); 若将它作为常规函数调用(即不加 new 操作符),将返回一个字符串,而非 Da...
Specifying a day higher than max, will not result in an error but add the overflow to the next month: Specifying: constd =newDate(2018,5,35,10,33,30); Is the same as: constd =newDate(2018,6,5,10,33,30); Try it Yourself » ...
