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 -- Tomasz Dziurko - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Disabling 'back'/'next' web browser button usage in application
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 On Wed, 2008-10-29 at 09:52 +0100, Tomasz Dziurko wrote: Hi.

Re: Disabling 'back'/'next' web browser button usage in application
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.

Re: Disabling 'back'/'next' web browser button usage in application
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? Regards -- Tomasz Dziurko - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Disabling 'back'/'next' web browser button usage in application
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.
