Scrolling

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

// Whenever you want the textarea to be scrolled to the bottom, do this:
longStringElement.scrollTop = longStringElement.scrollHeight;
</script>

<textarea id="longString"...... </textarea>

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
Marcin

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

news:ejhl49$h70$1@news.onet.pl...If you need to add content to the textarea programmatically, readonly won't
stop you, but it does seem to allow the '...scrollTop = ...scrollHeight'
trick to work in IE -- at least it did in IE7 for me.

Only if you need for the user to add content via the keyboard will readonly
cause you difficulties. Even then, one work-around may be to switch readonly
off and on at different times (e.g. set readonly to true briefly when you
add content programmatically and need to auto-scroll to the bottom).

Does this help?
