jQuery ON error. No error when using LIVE

Question

This is my current, i want to change .live but .on is not working..

$('#SearchString').live('keydown',function(e) {
if (e.which == 13) {
    if (!$("#SearchString").val()) {
        alert("Inget postnummer eller ort angiven!");
        return false;
    }
}
});




 $('#SearchString').on('keydown',function(e) {
if (e.which == 13) {
    if (!$("#SearchString").val()) {
        alert("Inget postnummer eller ort angiven!");
        return false;
    }
}
});

This is the ON version

What version of jQuery are you using? .on() was added in 1.7 http://api.jquery.com/on/ — Anton, Aug 26 '13 at 08:41
.live is aviable, in the version im using but.. Id rather not use it since im planning on upgrading to the newest. and .Live is removed then — Patrik Christoffersson, Aug 26 '13 at 08:42
@PatrikChristoffersson still you're not sharing the version of jQuery? — Praveen, Aug 26 '13 at 08:42
it should be `$(document).on('keydown', '#SearchString', function(){...})` — Arun P Johny, Aug 26 '13 at 08:42
Well, you didn't do the conversion correctly. Why don't you read the documentation? http://api.jquery.com/live/, http://learn.jquery.com/events/event-delegation/. — Felix Kling, Aug 26 '13 at 08:44

In event delegation model of on() the target element selector is passed as the second argument to the on() method.

$(document).on('keydown', '#SearchString', function(e){
    if (e.which == 13) {
        if (!$("#SearchString").val()) {
            alert("Inget postnummer eller ort angiven!");
            return false;
        }
    }
})
