Change layer visibility between two frames

[spiderbo]

Hi,

I have two framesets:

index.htm
|
----------------------
| |
index_nav.htm index_main.htm
(index_nav) (index_main)
Call to hidden layers |
|
-----------------
| |
nav.htm main.htm
(nav) (main)
hidden layers


The frame names are in brackets underneath the document names.

If I put the following javascript in index_nav.htm,
Code:
var doCheck = (top.parent.main.document.all!=null);


I get
Code:
"Error: 'top.parent.main.document' is null or not an object".


If I put a call to the hidden layers within the same frameset (nav.htm), I don't get any errors, i.e.,
Code:
var doCheck = (parent.main.document.all!=null);



Can anyone help? I seem to have tried every combination; parent.parent..., parent.frames[1]... and still keep getting errors.

Thank you for your response, I tried it and still receive the same error: "'top.main.document' is null or not an object".

Any more ideas?

The frame has definately loaded,

Have a look at the following really simple code:

You will see that the top frame INDEX_NAV, which is a parent to the MAIN frame does not work, however, the left hand frame NAV frame, which is in the same frame set as MAIN does work.

It looks like you named your lower frame index_main...

[spiderbo]

first frame set (index9.htm):
<FRAMESET rows="100,*" FRAMEBORDER=1 BORDER=1>
<FRAME NAME="index_nav" SRC="NAVpage9.html">
<FRAME NAME="index_main" SRC="MAINpage9.html">
</FRAMESET>


second frame set(MAINpage9.html):
<FRAMESET cols="200,*" FRAMEBORDER=1 BORDER=1>
<FRAME NAME="nav" SRC="index_main.htm">
<FRAME NAME="main" SRC="FirstMainPage9.html">
</FRAMESET>

So, it looks like you need to reference it like this, in your top frame:

top.index_main.main.document...

Thank you pyro, you have saved me hours of work, you are a genius!

Thanks also to Khalid, yours looked like it would have worked too, just a little more complicated.
