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(), Date.getMonth(), and Date.getDay()?

Answer 1

Altered piece of code I often use:

Date.prototype.yyyymmdd = function() {   var mm = this.getMonth() + 1; // getMonth() is zero-based   var dd = this.getDate();    return [this.getFullYear(),           (mm>9 ? '' : '0') + mm,           (dd>9 ? '' : '0') + dd          ].join(''); };  var date = new Date(); date.yyyymmdd(); 

Answer 2

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,"");    <!-- Next line is for code snippet output only -->  document.body.innerHTML += res;
