Disabling 'back'/'next' web browser button usage in application
Hi.
I have application which consists of questions to user provided in
some order. Each question is reachable on the same address, let's say
http://myApp/Question. Application engine knows which question to show
from database record. Each question page has 'Previous Question' and
'Next Question' buttons which increase/decrease questionNumber in
database and redirects to http://myApp/Question (which loads question
looking for its number in database).
My problem is:
How "disable" 'back' and 'next' button in web browser so user can go
to previous/next question only by using 'Previous Question' / 'Next
Question' button? Is there a way to remove whole page from session? So
user when clicks "back"/"next" will see custom communicate "your
session expired or you clicked 'back' or 'next' button on your web
browser while doing a test'. Or maybe I could achieve such
functionality in other way?
Thank you in advance for help
Regards

And any hint how to do this? :)
I thought about two possible ways to solve my problem:
1. on clicking Next/Prev Question button remove current page from
PageMap (although no idea how to do this yet ;) ) and then redirect
further, so when user use back button he will see session-expired-like
page
2. on clicking Next/Prev Question button invalidate Question and
answers model so (not sure, but think it works this way) when user
backs models will be loaded again.
What do you think?

it is too bad that there are no deployed examples of wicketstuff-jquery
project to see it in action.
What I've done is exactly this.
With HistoryAjaxBehavior you could listen for clicks on back/forward
button.

I think a better solution is to make the browser's back/forward buttons have
the same effect as clicking on the 'Previous Question'/'Next Question'
buttons. If you put effort into making that work instead of putting your
effort into trying to disable the browser's back/forward buttons, then you
will have a better application in the end -- one that the user's will
appreciate more.

Hi Tomasz,
Recently I integrated a JavaScript library with Wicket that could help
you with this particular application.
Take a look at the code and examples:
https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicketstuff-jquery/src/main/java/org/wicketstuff/jquery/ajaxbackbutton
https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicketstuff-jquery-examples/src/main/java/org/wicketstuff/jquery/ajaxbackbutton
The code is quite new and the example page is the only test for it, so
it could have some bugs ...
Try it and let me know whether it is in any help for you.
Martin
