如何在JavaScript中使用Moment.js格式化日期

Question

I'm using moment.js in my project, what I want is to convert a date in format dd-mm-yyyy to yyyy-mm-dd . I tried this but it didn't work, it gives me an invalid date:

alert(moment('14/10/2017').format('YYYY/MM/DD'));

Answer 1

You need to specify the current format of your date in moment() :

 var date = moment('14/10/2017', 'DD/MM/YYYY').format('YYYY/MM/DD'); console.log(date); // 2017/10/14
