    Hi!

    I have such code:

    <textarea name="text_field">very long text</textarea>

    I have filled in the value of textarea field. This value is a very long
    string.
    I would like to scroll this textarea field into the end.

    Would you like to help me how to do that?

    Thank you in advance

    Hi again!

    Unfortunately this example doesn`t work on IE.
    I have created such code:

    <script language=JavaScript>

    var biografiaElement = document.getElementById("biografia");
    var utworyElement = document.getElementById("utwory");

    alert(biografiaElement.scrollHeight);

    biografiaElement.scrollTop = biografiaElement.scrollHeight;
    utworyElement.scrollTop = utworyElement.scrollHeight;
    </script>

    Alert gives me 0 height and I don`t know why...

    Please help me.
    Thank you in advance

    Unfortunately this example doesn`t give me a solution I would like to have.
    I would like to have textarea element with updating possibilites.

    I tried

    var elem=document.getElementById("biografia");

    if(elem)
    {
    elem.focus();
    MoveToEnd(elem);
    elem.focus();
    }

    but also without results.
    I use IE 6.0.

    Please help me, I cannot find any properly-working solution in post
    archieves
    Thank you Andrew for helping
