[Prototype-core] Re: Why are all children of an 'update'd element being purged?
I understand that. And I was using update to clear the container and add a new element. My problem was, I have a reference to the previous element of the container that was just cleared, and I am saving that reference of the element with the intention of replacing the new container content with that element at some future time. Right now I'm using innerHTML = '', since using Element#update would wipe out the storage of the element I have a reference to, and that is highly undesirable.

Element#replace may be what you are looking for. Allen Madsen http://www.allenmadsen.com On Sat, Jul 3, 2010 at 6:00 AM, Viktor Kojouharov vkojouha...@gmail.com wrote: I understand that.

[Prototype-core] Re: Why are all children of an 'update'd element being purged?
Thanks for the clarification. Most methods that change content destroy the old content in favor of the new. The same is true for #replace suggested above. If you need to retain content while putting new content in its place, you may need a deep-clone method (which i've requested in the past and someone provided a possibility as an extension, but i couldn't get it to work). A search on this group for deep clone brings up a thread with a similar method and suggestions of additional arguments to control the amount of storage that gets copied. Another alternative could be to move the containers you need to preserve to some other, hidden, parent container before placing the new content. Sorry i wasn't more helpful. i'm a little rusty of late, being pressed for more C# development than web work lately. i hope one of the big- brains here can take a look and offer something for you. -joe t.
