Get String in YYYYMMDD format from JS date object?

Question

I\'m trying to use JS to turn a date object into a string in YYYYMMDD format. Is there an easier way than concatenating Date.getYear()

Answer 1

I didn't like adding to the prototype. An alternative would be:

var rightNow = new Date();
var res = rightNow.toISOString().slice(0,10).replace(/-/g,"");


document.body.innerHTML += res;
