Scrolling browser to newly visible panel?

[Gwyn Evans <gw...@gmail.com>]

Just wondering if there was anything that might help with the
following?

In a web page design I've been given, I may need to display an
'options' form to get additional input.  I'm doing this with Ajax,
but the problem is that it typically appears off the bottom of the
existing page - is there a good way of triggering the browser to do
something like scroll down, ideally to the bottom of the new form?

Best regards,
 Gwyn                          mailto:gwyn.evans@gmail.com

findpos(elem) has worked well for me on ajax-added elements:
http://www.quirksmode.org/js/findpos.html

Also this is good for the scrolling part:

And then if you wanted to animate the scrolling, and also wonder why 
this seemingly common need is not addressed by popular effects 
libraries, there's:

i found two possibilities to do this (although i haven't tried it with
wicket ajax):

var el = document.getElementById('panelInsertedViaAjax');
1)
document.getElementsByTagName('body')[0].scrollTop = el.offsetTop + el
.offsetHeight;
2)
el.scrollIntoView(false);
// false to position it to the bottom of the page
// true for the top
