Add 5 minutes to current time javascript
提问by venkat14
I am getting the current date as below:
我得到的当前日期如下：
var now = new Date();
I want to add 5 minutes to the existing time. The time is in 12 hour format. If the time is 3:46 AM, then I want to get 3:51 AM.
我想在现有时间上增加 5 分钟。时间采用 12 小时制。如果时间是凌晨 3:46，那么我想要凌晨 3:51。
function DateFormat(date) {
var days = date.getDate();
var year = date.getFullYear();
var month = (date.getMonth() + 1);
var hours = date.getHours();
var minutes = date.getMinutes();
var ampm = hours >= 12 ? 'PM' : 'AM';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0' + minutes : minutes;
var strTime = days + '/' + month + '/' + year + '/ ' + hours + ':' + minutes + ' ' + ampm;
// var strTime = hours + ':' + minutes + ' ' + ampm;
return strTime;
}
function OnlyTime(date) {
var days = date.getDate();
var year = date.getFullYear();
var month = (date.getMonth() + 1);
var hours = date.getHours();
var minutes = date.getMinutes();
var ampm = hours >= 12 ? 'PM' : 'AM';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0' + minutes : minutes;
// var strTime = days + '/' + month + '/' + year + '/ ' + hours + ':' + minutes + ' ' + ampm;
var strTime = hours + ':' + minutes + ' ' + ampm;
return strTime;
}
function convertTime(time)
{
var hours = Number(time.match(/^(\d+)/)[1]);
var minutes = Number(time.match(/:(\d+)/)[1]);
var AMPM = time.match(/\s(.*)$/)[1];
if (AMPM == "PM" && hours < 12) hours = hours + 12;
if (AMPM == "AM" && hours == 12) hours = hours - 12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if (hours < 10) sHours = "0" + sHours;
if (minutes < 10) sMinutes = "0" + sMinutes;
alert(sHours + ":" + sMinutes);
}
function addMinutes(date, minutes) {
return new Date(date.getTime() + minutes * 60000);
}
function convertTime(time)
{
var hours = Number(time.match(/^(\d+)/)[1]);
var minutes = Number(time.match(/:(\d+)/)[1]);
var AMPM = time.match(/\s(.*)$/)[1];
if (AMPM == "PM" && hours < 12) hours = hours + 12;
if (AMPM == "AM" && hours == 12) hours = hours - 12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if (hours < 10) sHours = "0" + sHours;
if (minutes < 10) sMinutes = "0" + sMinutes;
alert(sHours + ":" + sMinutes);
}
// calling way
var now = new Date();
now = DateFormat(now);
var next = addMinutes(now, 5);
next = OnlyTime(next);
var nowtime = convertTime(next);
How to add 5 minutes to the "now" variable? Thanks
如何向“now”变量添加 5 分钟？谢谢

You should use getTime()method.
你应该使用getTime()方法。
function AddMinutesToDate(date, minutes) {
return new Date(date.getTime() + minutes * 60000);
}
function AddMinutesToDate(date, minutes) {
return new Date(date.getTime() + minutes*60000);
}
function DateFormat(date){
var days = date.getDate();
var year = date.getFullYear();
var month = (date.getMonth()+1);
var hours = date.getHours();
var minutes = date.getMinutes();
minutes = minutes < 10 ? '0' + minutes : minutes;
var strTime = days + '/' + month + '/' + year + '/ '+hours + ':' + minutes;
return strTime;
}
var now = new Date();
console.log(DateFormat(now));
var next = AddMinutesToDate(now,5);

get minutes and add 5 to it and set minutes
获取分钟并添加 5 并设置分钟
var s = new Date();
console.log(s)
s.setMinutes(s.getMinutes()+5);
console.log(s)回答by Emil S. J?rgensen
//Date objects really covers milliseconds since 1970, with a lot of methods
//The most direct way to add 5 minutes to a Date object on creation is to add (minutes_you_want * 60 seconds * 1000 milliseconds)
var now = new Date(Date.now() + (5 * 60 * 1000));
console.log(now, new Date());回答by OliverRadini
Quite easy with JS, but to add a slight bit of variety to the answers, here's a way to do it with moment.js, which is a popular library for handling dates/times:
使用 JS 很容易，但为了给答案添加一点多样性，这里有一种使用 moment.js 的方法，它是处理日期/时间的流行库：

var now = moment();
var future = now.add(5, 'minutes');
console.log(future.format("YYYY-MM-DD hh:mm"))

Try this:
尝试这个：
var newDateObj = new Date();
newDateObj.setTime(oldDateObj.getTime() + (5 * 60 * 1000));

I'll give a very shortanswer on how to add anystring of the form ny:nw:nd:nh:nm:nswhere nis a number to the Dateobject:
我给一个很短的如何添加回答任何形式的字符串ny:nw:nd:nh:nm:ns，其中n是一个数字的Date对象：
/**
* Adds any date string to a Date object.
* The date string can be in any format like 'ny:nw:nd:nh:nm:ns' where 'n' are
* numbers and 'y' is for 'year', etc. or, you can have 'Y' or 'Year' or
* 'YEar' etc.
* The string's delimiter can be anything you like.
*
* @param Date date The Date object
* @param string t The date string to add
* @param string delim The delimiter used inside the date string
*/
function addDate (date, t, delim) {
var delim = (delim)? delim : ':',
x = 0,
z = 0,
arr = t.split(delim);
for(var i = 0; i < arr.length; i++) {
z = parseInt(arr[i], 10);
if (z != NaN) {
var y = /^\d+?y/i.test(arr[i])? 31556926: 0; //years
var w = /^\d+?w/i.test(arr[i])? 604800: 0; //weeks
var d = /^\d+?d/i.test(arr[i])? 86400: 0; //days
var h = /^\d+?h/i.test(arr[i])? 3600: 0; //hours
var m = /^\d+?m/i.test(arr[i])? 60: 0; //minutes
var s = /^\d+?s/i.test(arr[i])? 1: 0; //seconds
x += z * (y + w + d + h + m + s);
}
}
date.setSeconds(date.getSeconds() + x);
}
Test it:
测试一下：
var x = new Date();
console.log(x); //before
console.log('adds 1h:6m:20s');
addDate(x, '1h:6m:20s');
console.log(x); //after
console.log('adds 13m/30s');
addDate(x, '13m/30s', '/');
console.log(x); //after
Have fun!
玩得开心！

This function will accept ISO format and also receives minutes as parameter.
此函数将接受 ISO 格式并接收分钟作为参数。
function addSomeMinutesToTime(startTime: string | Date, minutestoAdd: number): string {
const dateObj = new Date(startTime);
const newDateInNumber = dateObj.setMinutes(dateObj.getMinutes() + minutestoAdd);
const processedTime = new Date(newDateInNumber).toISOString();
console.log(processedTime)
return processedTime;
}

return this;
}
let now = new Date( );
console.log(now);
now.AddMinutes( 5 );
