使用 moment.js 获取到月底的剩余天数

Question

I want to display or hide a link depending on whether there are less than 2 weeks left in the month, using moment.js, but I'm not sure the correct way to go about it.

Currently I have...

if (moment().endOf('month')<=(13, 'days'))
{
    //do link stuff here
}

...but I don't think that's the correct way of doing it. It certainly isn't doing anything anyway. Could anyone give me any pointers? Thanks in advance.

Answer 1

You could do something like this:

var a = moment().endOf('month');
var b = moment();

if(a.diff(b, 'days') <= 13)
{
    //do something
}

Answer 2

If you're looking for a plain javascript version, I've wrote this function:

function getMonthDaysLeft(){
    date = new Date();
    return new Date(date.getFullYear(), date.getMonth() + 1, 0).getDate() - date.getDate();
}

Answer 3

Maybe something like this can help.

const d = moment();
const currentDay = d.get("date");
const daysInMonth = d.daysInMonth();
const remainingDays = daysInMonth - currentDay;

console.log(remainingDays <= 13)
