Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

    Javascript: Key Detection

    I have a function that is called on the onkeyup event for a textarea:
    lArea.onkeyup = updateLivePreview;
    in my updateLivePreview function I need to check if the key that was released was infact the Enter button, if so do x else do y. How would I acheive this?
    Build a man a fire and he is warm for a day.
    Set a man on fire and he is warm for the rest of his life.

    Hi Sammo

    Try this

    function updateLivePreview(e)
    var code;
    if (!e) var e = window.event;
    if (e.keyCode) code = e.keyCode;
    else if (e.which) code = e.which;
    if (code == 13){
    alert("Enter is pressed");
