.day() returns wrong day of month with Moment.js
提问by Yaron Levi
I am using Moment.js to parse a string and get the day, month and year separately:
我正在使用 Moment.js 来解析字符串并分别获取日、月和年：
var date = moment("12-25-1995", "MM-DD-YYYY");
var day = date.day();
However, dayis not 25—it's 1. What is the correct API method?
但是，day不是 25，而是 1。正确的 API 方法是什么？
回答by David Sherret
The correct function to use is .date():
要使用的正确功能是.date()：
date.date() === 25;
.day()gives you the day of the week. This works similarly to javascript's .getDate()and .getDay()functions on the date object.
.day()给你星期几。这与日期对象上的javascript.getDate()和.getDay()函数类似。
If you want to get the month and year, you can use the .month()and .year()functions.

This how to get parts of date:
这是如何获取部分日期：
var date = moment("12-25-1995", "MM-DD-YYYY");
if (date.isValid()) {
day = date.date();
console.log('day ' + day);
month = date.month() + 1;
console.log('month ' + month);
year = date.year();
console.log('year '+ urlDateMoment.year());
} else {
console.log('Date is not valid! ');
}
回答by Muhamed Krasniqi
You can use moment().format('DD')to get the day of month.
您可以使用moment().format('DD')来获取月份的日期。
var date = +moment("12-25-1995", "MM-DD-YYYY").format('DD');
// notice the `+` which will convert
// the returned string to a number.
Good Luck...
祝你好运...
