[Javascript] Enumerating Other Window

[David Lovering]

It isn't quite that simple.

When a program spawns a remote, the parent can do pretty much as you said,
and use

    windowname.document.formname.varname.attribute  -- OR --
    windowname.document.framename.document.formname.varname.attribute
// one or more frames

to call up the bits in the child window(s).

When the child program wants to access items in the parent window, it is a
bit more complicated.

    For a single form, no-frame parent:

    window.opener.document.formname.varname.attribute

    For multiframe, multiform parent(s):

    window.opener.parent.document.formname.varname.attribute -- OR --

window.opener.parent.document.framename.document.formname.varname.attribute

  It gets REALLY tedious when you start embedding things inside <OBJECT>
declarations, as it appears with
MicroSloth's defective DOM structure you can only go from the parent to the
child, and not backwards.  I won't even attempt to give you a path map for
this -- it is too complicated to explain lucidly in a few sentences.

  The reason the second 'document' declarations are needed inside pages with
frames is that the frame acts as a document boundary, and to access the
internals of one you must 'bust-through' the hard outer layer to get at the
soft and chewy insides.

  Hope this helps.
