Is there a way to make moment.js output “1 day” in

问题:

I'm using the Time to X function of Moment.js. When the second parameter is true, then the result is a day. Is there a way to make this 1 day through the API, or will I need to do a string replace?

回答1:

You can use the string.replace method to replace "a day" with "1 day".

Or you can try like this:

var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
var differenceInMillisec = a.diff(b);
var differenceInDays = a.diff(b, 'days'); //Output 1 day

回答2:

well, sometimes when the result is very simple, just go for it. a string replace is just one line of code... Even if there is a solution with the api, I'm sure it would be more "complicated" than doing a string replace... or just write a reusable function and call that function on the result like : replaceString(Time_to_X); where replaceString is a function using a string replace

I've got a simple 100% solution to your question:

moment.localeData()._relativeTime.d = '1 day'; // override 
console.log( moment.duration(1, 'days') );     // = '1 day', not 'a day'.
