Moment js get first and last day of current month
提问by user3574492
How do I get the first and last day and time of the current month in the following format in moment.js:
如何在 moment.js 中以以下格式获取当月的第一天和最后一天以及时间：
2016-09-01 00:00
2016-09-01 00:00
I can get the current date and time like this:
moment().format('YYYY-MM-DD h:m')which will output in the above format.
我可以像这样获取当前日期和时间：
moment().format('YYYY-MM-DD h:m')它将以上述格式输出。
However I need to get the date and time of the first and last day of the current month, any way to do this?
但是我需要获取当月第一天和最后一天的日期和时间，有什么办法吗？
EDIT:My question is different from thisone because that asks for a given month that the user already has whereas I am asking for the currentmonth along with asking for a specific format of the date that is not mentioned in the other so called 'duplicate'.
编辑：我的问题与此不同，因为它要求用户已经拥有的给定月份，而我要求的是当前月份以及其他所谓的“重复”中未提及的特定日期格式'。

In case anyone missed the comments on the original question, you can use built-in methods (works as of Moment 1.7):
如果有人错过了对原始问题的评论，您可以使用内置方法（适用于 Moment 1.7）：
const startOfMonth = moment().startOf('month').format('YYYY-MM-DD hh:mm');
const endOfMonth = moment().endOf('month').format('YYYY-MM-DD hh:mm');

There would be another way to do this:
还有另一种方法可以做到这一点：
var begin = moment().format("YYYY-MM-01");
var end = moment().format("YYYY-MM-") + moment().daysInMonth();
回答by Kevin Grosgojat
You can do this without moment.js
你可以在没有 moment.js 的情况下做到这一点
A way to do this in native Javascript code :
一种在本机 Javascript 代码中执行此操作的方法：
var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);
firstDay = moment(firstDay).format(yourFormat);
lastDay = moment(lastDay).format(yourFormat);

Assuming you are using a Date range Picker to retrieve the dates. You could do something like to to get what you want.
假设您使用日期范围选择器来检索日期。你可以做一些类似的事情来得到你想要的。
$('#daterange-btn').daterangepicker({
ranges: {
'Today': [moment(), moment()],
'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
'Last 7 Days': [moment().subtract(6, 'days'), moment()],
'Last 30 Days': [moment().subtract(29, 'days'), moment()],
'This Month': [moment().startOf('month'), moment().endOf('month')],
'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')]
},
startDate: moment().subtract(29, 'days'),
endDate: moment()
}, function (start, end) {
alert( 'Date is between' + start.format('YYYY-MM-DD h:m') + 'and' + end.format('YYYY-MM-DD h:m')}

moment startOf()and endOf()is the answer you are searching for.. For Example:-
时刻startOf()和endOf()是您正在寻找的答案.. 例如：-
moment().startOf('year'); // set to January 1st, 12:00 am this year
moment().startOf('month'); // set to the first of this month, 12:00 am
moment().startOf('week'); // set to the first day of this week, 12:00 am
moment().startOf('day'); // set to 12:00 am today

当月的第一个和最后一个日期在 moment.js

const firstdate = moment().startOf('month').format('DD-MM-YYYY');
console.log(firstdate);
console.log("current month last date");
const lastdate=moment().endOf('month').format("DD-MM-YYYY");
console.log(lastdate);

As simple we can use daysInMonth()and endOf()
很简单，我们可以使用daysInMonth()和endOf()
const firstDay = moment('2016-09-15 00:00', 'YYYY-MM-DD h:m').startOf('month').format('D')
const lastDay = moment('2016-09-15 00:00', 'YYYY-MM-DD h:m').endOf('month').format('D')
