frames and back action

F

Flyzone

Hello, I have a page defined like this:

<html>
<frameset>
<frame src="./topone.pl">
<frameset>
<frame src="./frame1.pl">
<frame src="./frame2.pl">
</frameset>
</frameset>
</html>

Then I click in one link in the first page and the mainpage, frame1
and frame2 change the page show.
The problem is that when pressing the "back" action, just the frame2
change, than I need to press other two times the "back" to arrive in
the original page/frames.

Does exist a back action (-3)? I tried the code:
window.onback = history.back(-3);
without success (FF e IE7)

Any help will be appreciate
Thanks in advance

Hi,

Yes, that is because the browser thinks you want to go back if you hit
the BACK button.
What if you actually wanted to go back only from your last click in some
frame, and the browser decides to go back in all frames? What is some of
those frames don't have a history to go back to?

What you see is normal and desired behaviour.

If you MUST sync your frames somehow, you'll have to build that
explicity in JavaScript. But of course your pages will fail when a user
has it disabled.
That is about 10% of the websurfers I think.
Warning: Thomas Pointedears once told me that 138% of the statistics you
find on the web are flawed. ;-)

Solution?
Don't use frames and avoid this whole mess. Or make a working syncing
mechanism in JavaScript.

I cannot avoid frames (many reasons for this), but I however have the
problem with the back action...
From msdn website seems not exist and if I try to use it in a
webpage,
the action is made when loading the page.
So..how to intercept the back button of the browser?

Thanks...

Hi,

I cannot follow everything you wrote, but I can maybe help with the last
question: "So..how to intercept the back button of the browser?"

Have a look at the unload event handler, eg:
<body onUnLoad="alert('bye');">

Maybe you can do the syncing in there?

An intranet does not exist in a vacuum either.

Just a little problem....the first frame is reloaded itself
every 5 seconds....the onUnload is activated also on this...
I made a little more investigation and the onback action
doesn't exist (in msdn library)...

I could solve putting a back-button in the first frame with:
onClick=\"top.history.go(-3);

But I would like to intercept the back button of the browser
(for the backspace I don't have this problem).

Well..maybe I have missed somethings in the pre-project
thinking to use the frames :p

Hi,

Well, in all honesty, I don't think anybody in here can help you since
we don't know the requirements of your webapplication. SO we cannot help
you with the syncing of the contents in the frames.

Personally I am also inclined to advise you to make a better design. (Or
your bosses). Syncing frames sounds to me like bad design.
There are probably better, more robust, ways to solve the problem at hand.

Yes, like the last ten years or so.
