jQuery - keydown / keypress /keyup ENTERKEY detection?

JavaScript/jQuery

$("#entersomething").keyup(function(e){ 
    var code = e.key; // recommended to use e.key, it's normalized across devices and languages
    if(code==="Enter") e.preventDefault();
    if(code===" " || code==="Enter" || code===","|| code===";"){
        $("#displaysomething").html($(this).val());
    } // missing closing if brace
});

HTML

<input id="entersomething" type="text" /> <!-- put a type attribute in -->
<div id="displaysomething"></div>

I think you'll struggle with keyup event - as it first triggers keypress - and you won't be able to stop the propagation of the second one if you want to exclude the Enter Key.

update: nowadays we have mobile and custom keyboards and we cannot continue trusting these arbitrary key codes such as 13 and 186. in other words, stop using event.which/event.keyCode and start using event.key:

if (event.key === "Enter" || event.key === "ArrowUp" || event.key === "ArrowDown")

jQuery Sparkle includes a custom event for this. The source can be seen here: http://github.com/balupton/jquery-sparkle/blob/master/scripts/resources/jquery.events.js
