如何在JavaScript中获得ISO 8601周的开始和结束日期时间？

Question

If I have the Year (say 2013) and the ISO week (say 35), how do I get the Starting and Ending DateTime in pure JavaScript?

Is there any specific Library for dealing with DateTime in JavaScript?

Answer 1

As far as a library, there is http://www.datejs.com/ . Or http://phpjs.org/functions/date/ .

Answer 2

Try

var date  = new Date('01 Jan ' + year);
date.setDate(35 * 7);
date.setDate(date.getDate() - date.getDay()) //it will give the start of the week
