Convert mm/dd/yyyy to yyyy-mm-dd

Question

I need to convert a date like this, 03/07/2016 to a date format like, 2016-03-07.

How can I do this using javascript or jquery?

Answer 1

Assuming your input is a string, this is easy to do using a regular expression with the String .replace() method:

var input = "03/07/2016";
var output = input.replace(/(\d\d)\/(\d\d)\/(\d{4})/, "$3-$1-$2");

Actually, if the input format is guaranteed, you could just swap the pieces around based on their position without bothering to explicitly match digits and forward slashes:

var output = input.replace(/(..).(..).(....)/, "$3-$1-$2");
