[Javascript] <OBJECT> dereferencing

Wed Mar 12 08:14:41 CST 2003

I was thinkin' you could just use a top level frame for all pages to fit
within to give you a top.framename to get back up, but it sounds like a
better way would be to use the id attributes which would probably need to
have unique names in a schema that would allow you to get around using them.
You could then access them with the enumerator object IIRC.

Dear Tom:

  Some of my other applications use frames, so yes, I am familiar with what
they can do.  However, frames are "fixed" to the window space [yes, there
are
ways of dynamicly moving them about, but they are somewhat pathological],
and
I want things that close-up when they are deleted, can be scrolled as sets,
and generally manipulated on a "rubber" background -- none of which are easy
(or possible) with the conventional frame architecture.

  Basicly, I need to know how to reference back to the parent object that
contains the <OBJECT> declaration that contains the code snippet, as seen
from the internal code snippet.  The rest I can figure out using the tools I
have available to me.
