Answer 1

Cut your date string into 3 pieces, reverse order, and glue it back

"2014-12-03".split('-').reverse().join('-'); // "03-12-2014"

Breakdown:

1. "2014-12-03" - string
2. ['2014','12','03'] - create an array by splitting each string which isn't -
3. ['03','12','2014'] - reversing the array
4. "03-12-2014" - joining all items in the array and putting - between them.

Answer 2

How about this:

var from = "2014-12-03"; 

function convert(date){
    var d=new Date(date);
    function addLeadingZero(d){
        return (d<10)?"0"+d:d;
    }
    return [d.getDay(), d.getMonth()+1, d.getFullYear()].map(addLeadingZero).join("-");
}

console.log(convert(from));

Fiddle updated.

If I were you I'd use momentJS , it'll handle this kind of thing for you. If you pull in the library all you'll need to do is:

var from = moment("2014-12-03", "YYYY-MM-DD");
var date = moment.format("DD/MM/YYYY");
alert(date);

Much easier than trying to roll your own solution and if you ever need to support additional formats it'll make your life easy.
