function getD() {
var d = new Date("12/12/2012");
var month = d.getMonth()+1;
var day   = d.getDate();
var year  = d.getFullYear();

alert( month + "/" + day + "/" + year);
                }

Update

HTML:

$('#clickme').click(function() {
  var thetestdate = $('#testdate').val();
  mynewdate = getD(thetestdate);
  alert(mynewdate);
});

JS:

function getD(mydatevariable) {
var d = new Date(mydatevariable);
var month = d.getMonth()+1;
var day   = d.getDate();
var year  = d.getFullYear();
var wholedate = ( month + "-" + day + "-" + year);
return wholedate;
                               }

Quote the argument:

var d= new Date("12/12/2012");

Here's an updated fiddle. You're currently creating a date with the result of the expression 12/12/2012, which is three numbers and two division operators:

console.log(12 / 12 / 2012); // 0.0004970178926441351

Please stop answering duplicates instead of marking them ;) – plalx Oct 18 '13 at 13:32
@plalx - I find it quicker and more helpful to the OP to answer the question when it's such a simple one. If a duplicate then appears I always vote to close as well. – James Allardice Oct 18 '13 at 13:33
Perhaps it's faster but it pollutes SO and doesn't condition people to search before asking. (I did not downvote btw) – plalx Oct 18 '13 at 13:35
@plalx - I don't think it pollutes SO since the question will get closed as a dupe anyway. True about conditioning people to search before asking though. Here is not the place for this discussion though, I think it's been brought up on meta several times (where your approach does tend to be the accepted one I admit). – James Allardice Oct 18 '13 at 13:36
@plalx - Also, just closing as a dupe doesn't explain to the OP what's going wrong in their particular case. – James Allardice Oct 18 '13 at 13:38

You can always post a comment. I guess there could be cases where the question is complex enough to answer it even if it seems to be a possible duplicate, however it shouldn't be the norm. – plalx Oct 18 '13 at 13:40

You're creating a new date based on

(12 / 12) / 2012 == 0.0004970178926441351

which will be some fraction of a second after January 1, 1970.

You can create a Javascript date by parsing a string:

new Date( "12/12/2012");

or by passing in individual components:

new Date( 2012, 12, 12 );

See Date at MDN for more variations.
