Javascript date - Leading 0 for days and months where applicable

Question

Is there a clean way of adding a 0 in front of the day or month when the day or month is less than 10:

var myDate = new Date(); var prettyDate =(myDate.getFullYear() +'-'+ myDate.getMonth()) +'-'+ myDate.getDate(); 

This would output as:

2011-8-8 

I would like it to be:

2011-08-08 

Answer 1

The format you seem to want looks like ISO. So take advantage of toISOString():

var d = new Date(); var date = d.toISOString().slice(0,10); // "2014-05-12" 

Answer 2

No, there is no nice way to do it. You have to resort to something like:

var myDate = new Date();  var year = myDate.getFullYear();  var month = myDate.getMonth() + 1; if(month <= 9)     month = '0'+month;  var day= myDate.getDate(); if(day <= 9)     day = '0'+day;  var prettyDate = year +'-'+ month +'-'+ day;
