Is there any way to do two (or more) $(''element'').setStyle
changes
atomically? I''m trying to do a Tab control, where one <div> is
hidden
as another appears, but I occasionally get flickering when (for a
split second) both <div> elements are visible simultaneously.
My calls are:
-- div1.setStyle({height: div2.getHeight()+''px''});
-- div2.setStyle({height: 0});
For reasons specific to my code, I can''t use "display:none"
to make it
invisible; I have to use height. But sometimes, right in between these
commands, both div1 & div2 occupy space in the document flow, causing
the page to flicker. If I were simply to reverse the commands, then it
will flicker in the other direction, so that won''t help,
unfortunately.
Any help would be greatly appreciated.
Thanks,
Jonathan

By the way, I''m using standard Prototype and Scriptaculous for this (I forgot to make that clear before) On Oct 25, 7:57 pm, Jonathan <jonsol...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Is there any way to do two (or more) $(''element'').setStyle changes > atomically?

I takes a few moments to write your own (very simple) function, something like: function swapHeights(el1, el2) { el1.setStyle(...); el2.setStyle(...) } or maybe you''d like to extend Element.methods. -- Rob --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

My question, I guess, is whether there''s a way to make multiple calls to setStyle before any of them take effect. Essentially, I want the next browser update to have the results of both changes. I do not want to permit the browser to update in between (after the first but before the second). I''m not looking for something specific to my needs, for setting the Height specifically. I''m just wondering if there''s any way to solve this general problem.

Any flickering that you see may be the result of other scripts running while the browser is trying to update, hence the flickering. You can only fix that by changing when the other scripts run, not the style setting function itself.> I''m not looking for something specific to my needs, for setting the > Height specifically.
