Changing the format of a date string

Question

I have a date string, 04-11-2010, in JavaScript I want to have a function that will convert it to 2010-11-04.

Does anyone know how I can do

Answer 1

Top of my head:

 var dt1   = parseInt(ab.substring(0,2),10);
 var mon1  = parseInt(ab.substring(3,5),10);
 var yr1   = parseInt(ab.substring(6,10),10);

Then you have the pieces you need.
