Submit form with Enter key without submit button? [duplicate]

$("input").keypress(function(event) {
    if (event.which == 13) {
        event.preventDefault();
        $("form").submit();
    }
});

Change #form to your form's ID

$('#form input').keydown(function(e) {
    if (e.keyCode == 13) {
        $('#form').submit();
    }
});

Or alternatively

$('input').keydown(function(e) {
    if (e.keyCode == 13) {
        $(this).closest('form').submit();
    }
});
