It is probably better to make the addHours method immutable by returning a copy of the Date object rather than mutating its parameter. Date.prototype.addHours= function(h){ var copiedDate = new Date(this.getTime()); copiedDate.setHours(copiedDate.getHours()+h); return copiedDate; } Th...
## 問題描述 使用 JavaScript 為日期添加小時和分鐘 (Adding hours and minutes to a date with JavaScript) I am building a meeting calendar based on time zones around the world. My problem is how to add or subtract the time zone from the user selected date
functionaddHoursToDate(objDate,intHours){varnumberOfMlSeconds=objDate.getTime();varaddMlSeconds=(intHours*60)*60*1000;varnewDateObj=newDate(numberOfMlSeconds+addMlSeconds);returnnewDateObj;} Here’s how you can call it to get, for example, a date exactly one day in the future. ...
在上述示例中,首先将日期和时间分别存储在datePickerDate和timePickerTime变量中。然后,使用split()方法将日期字符串和时间字符串拆分为数值数组,并将其存储在[year, month, day]和[hours, minutes]变量中。最后,使用这些值创建一个新的Date对象,注意按照 JavaScript 的月份规则,需要将月份减去1。这样就得到了一个包...
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...
.getDate() Returns the date of the month. (1-31) .getDay() Returns the day-of-week as a number. (0-6) Sun=0, Mon=1, Tue=2, etc. .getHours() Returns the hour of the day. (0-23) .getMinutes() Returns the minute of the hour. (0-59) ...
Date.prototype.addHours=function(value) {if(!value || isNaN(value)) value = 0;this.setHours(this.getHours() +value);returnthis; }; Date.prototype.addMinutes=function(value) {if(!value || isNaN(value)) value = 0;this.setMinutes(this.getMinutes() +value);returnthis; ...
Date.prototype.setMonth(month[, day]):设置月份。 Date.prototype.setDate(day):设置日期。 Date.prototype.setHours(hour[, min[, sec[, ms]]]):设置小时数。 Date.prototype.setMinutes(min[, sec[, ms]]):设置分钟数。 Date.prototype.setSeconds(sec[, ms]):设置秒数。
