You can prevent user to type white space like this just return false if keycode is 32 otherwise return true

$("input").on("keydown", function (e) {
    return e.which !== 32;
});

JS Fiddle Example

Note: You have mentioned Key code 38 but this is for UP arrow key not for Space

Here is the list of Key Code, but unfortunately author didn't include the space's Key code in this list :)
