Hehehehe.... funnyyyyy... :-)
Okay, let me rephrase: Can anybody help me, and tell me how to emulate
'history.back() ' USING JAVASCRIPT CODE, without using the history object?

every browser i've ever seen already has the ability to return to the
previous resource built in and it works which is a good thing
considering its the most used function after the humble little link.

you are trying to re-invent the wheel and it will be at best square.
you are wasting your time.

Sorry, window.location and document.refere r, of course.

My Mozilla Firebird v0.6 has no problems with it.
Can you show a live page where it fails?

I'm sorry Jacqui or (maybe) Pete, I don't know if you have read the message,
but I discovered that the HISTORY object seems not supported by Gecko in
strict mode. And that is exactly the object that is used in the 'solution'
you point me to.
You are right to argue the use of a history.back() function in JavaScript.
What I want to do, is create a sort of 'wizard' application, such as you
commonly see in Windows when going through complex tasks. These
applications often have a 'next' button, going to the next step, and a
'previous' button going to the previous step.
Of course I could create all kinds of complex scripts for the 'previous'
button, retrieving previously entered information from cookies, session
variables or database fields, but a simple 'history.back() ' JavaScript
function also does the trick. That is, on every JavaScript-enabled browser
except for Gecko in strict mode...
Now, before resorting to writing complex code for that one set of browsers,
I was trying to find out if there was another simple way to go 'back in
history'...

Belay that. You are right. Document.refere r could be refered[sic] to client
side to insert the relevent link into the document *provided* the browser
provides said datum in its request for the page.

Cheers
Richard.

The code I wrote is enough to duplicate the problem on Mozilla 1.5a. Just
copy those 3 lines to an empty HTML file, run it, see the empty results
page, and check the JavaScript Console under Tools > Web Development >
JavaScript Console...
I am now downloading Firebird v0.6.1 to check the problem there...

Okay, the problem is not there in Firebird v.0.6.1, so maybe it is a
Mozilla-specific problem?

....
The source I pointed you to uses 'history.back() ' and works fine in
Mozilla 1.5b.

Re: Javascript 'history' object unavailable in Mozilla/Gecko/Netscape in strict mode??

Okay everybody, thanks for your support! I've found the solution to my
problem...
It seems that this is indeed a bug in Mozilla 1.5a. I've just downloaded
the newest 'nightly build' (1.5b) and it works there...

Now... I assume you know the URI that the 'next' button is going to take the
user to, and that will have to be coded into each page. You say this is a
wizard style thing, so I'm also going to assume it is a sequential affair -
stage 1 -> stage 2 -> stage 3 -> finished - that kind of thing... does it
not follow that you should know where the user came from, and can then code
that URI into the 'previous' button. Eg. You are at stage 2 of the wizard.
<p><a href="stage1.ht ml">Previous</a> | <a
href="stage3.ht ml">Next</a></p>... that sort of thing...

Just a thought... feel free to tell me if I am barking up the wrong tree!
