I'm receiving an ajax response that has a date in the format mm/dd/yy. How can I convert this to the format yyyy-mm-dd using jquery? Does jquery have an internal function to do this?

- 1 @mVChr it's lame but generally you assume that 2-digit numbers greater than something like 90 (depends on the application) are in the 1900s, and 2-digit years smaller than that are in this century. – Pointy Commented Feb 22, 2011 at 22:59

Reset to default 4Simple with no checking of the input (JavaScript, no jQuery):
var d = '01/25/90'; // as an example
var yy = d.substr(6,2);
var newdate = (yy < 90) ? '20' + yy : '19' + yy;
newdate += '-' + d.substr(0,2) + '-' + d.substr(3,2); //1990-01-25
That sort of thing is not what jQuery is designed to facilitate. The jQuery library is primarily about DOM manipulation, with various concessions made to code structure convenience.
What you need to do is split up the ining address as text and either reconstruct it as a pliant JavaScript parseable date, or else just get the year, month, and day from the string and use the javascript "Date()" constructor that takes those as numeric values.This code will give you a Date from your format:
This code will give you a Date from your format:
function toDate(str) {
var rv = null;
str.replace(/^(\d\d)\/(\d\d)\/(\d\d)\$/, function(d, yy, mm, dd) {
if (!d) throw "Bad date: " + str;
yy = parseInt(yy, 10);
yy = yy < 90 ? 2000 + yy : 1900 + yy;
rv = new Date(yy, parseInt(mm, 10) - 1, parseInt(dd, 10));
return null;
});
return rv;
}

$(document).ready(function(){
$("#date").change(function(){
var $d = $(this).val();
var $yy = $d.substr(6,4);
var $dd = $d.substr(3,2);
var $mm = $d.substr(0,2);
var $newdate = $yy + '-' + $mm + '-' + $dd;
$("#date").val($newdate);
});
})
