I want to know how you guys deal with back button issues in your web applications.
I can not forbid users to click back button on their browser, but when they hit it, the page code doesn't run. So writing in page_load() makes no sense.
I have searched online and found this link: Disabling Back button on the browser. It does not work for me. Any idea?
There is no way to disable the back button. You can try to open your page/form in a new window so there would be nothing to navigate back to
Normally, If I have a critical or lengthy form, I tend to maintain a dirty-flag and if the user starts entering something, the dirty-flag gets set and on save or submit it gets reset. You can use unload/beforeunload javascript event to see if the dirty-flag is set and ask for confirmation.

I want to go previous page when the user clicks on the browser back button. When I navigate another page, I can not go to the last page by using the browser back button. So, can anyone help me find a solution to this problem?
Ensure that every state that you want to show up in next/back is differentiated by a route change navigated to by NavigationManager.
If you make a page /somePage and you let the user step through several choices, and then the user navigates (using the URL bar) then hits the back button on the browser, they will go back to /somePage and not back to the choices they made.
If you make a page /somePage and each time the user makes a choice they are navigated to a new page using NavigationManager, for example /somePage/someSelection, then when they hit back they will go back to /somePage/someSelection. This requires you to load data on subpage choices on init based on optional page route parameters, but the tradeoff is having browser navigations that are part of next/back.
My problem is that after clicking the Browser back button the code in the BeforePagesLoad-Event not triggered. There is a function to get set an object in a manged bean.

Is there a way to trigger a event after clicking the browser back button?
I am no x-pages expert, but it looks to be a server side technology, meaning that a server call must be made in order for the code to run.
The first thread is a solution for forcing a page reload via cookies, while the second involves javascript/jquery. The second also may touch on some cache control of different browsers.
Force a page refresh when page visited from back button
Is there a cross-browser onload event when clicking the back button?
Any Xpages application update in design causes the application refresh which removes scope variables, session etc. When this occures and there is a page opened in users browser with some partial refresh action buttons ... such buttons simply do nothing when clicked which is quite confusing. No message that's warning the user that the page is stale or something. Is there a way how to detect such situation in general so I can inform user in browser with some dialog that he should reload the entire page?
For all scope variables above request (which gets initialized when you send a request and is always shiny and new) you never can take their existence for granted. Best example: user leaves a form open, locks the PC, goes for lunch, lets the session expire (which also deletes the view scope). (S)he comes back, opens a new tab and logs in - so there is a valid (new) session, hits submit in the first tab -> bum all your code fails.
This is the same scenario as an updated design short of the scenario Panu was pointing to.
So in your code check for the existence of your scoped variables and force a full refresh. Or (I like that better) add an error to the page so that gets displayed with an appropriate action.
I'm trying to launch a "logout" page if the usesr closes the browser...I've looked for a couple of days and I think I have looked at all of the related topics...tried quite a few...but so far, nothing is working the way I need it to...
Everything seems to trigger just navigating to the next page...I want to be able to navigate the site and NOTHING IF I LOG OUT...but if I CLOSE THE BROWSER (or the DOMAIN changes), I want to fire the logout page.
Actually, it really doesn't need to open a popup...but that would be my preference...
Thanks for any help in getting a definitive answer...
HOLD THE PHONE...
Just FYI...I found what seems to be working here:
[http://eureka.ykyuen.info/2011/02/22/jquery-javascript-capture-the-browser-or-tab-closed-event/][1]
...and it also seems that there are some very useful variations from contributers.
I also added a line to the original script to execute my logout page...
You should be able to add a listener using onbeforeunload and ask the user if they want to log out in the prompt https://developer.mozilla.org/en-US/docs/DOM/window.onbeforeunload
I'm facing a strange problem here, i have used a sample code of graph api's (reallylongaddress-iPhone-Facebook-Graph-API-59e6399, Created by , https://github.com/reallylongaddress/iPhone-Facebook-Graph-API) which was available on github. And i faced these problems:-
1) I'm having a share button of my own , when i click on it to login to fb a white view (or popup ) apears for almost 5 seconds and it appears evry time when i click on share button to share something on my facebook wall, even if i'm logged in . I reduced this problem to only one time.
2) The second and main problem now i'm facing is that on login it doesn't have any close button on it , and user must have to login ,other wise the application will not continue. Can i place a close button on this fb login web view?
NOTE:I have also used the fbconnect earlier but i dont wanna use publish dialog box ,, which shows user a dialog box and then user can press on "pulish" or "skip" button. instead i want that what ever the user wants to share on wall can be shared on just one tap on a button. That is why i have used this sample code, but it also has these two problems i have specified above.
Please help me with these 2 problems above or suggest me any other alternative option which does not have the "publish.stream" dialog box.
Thanks
In this condition Facebook controller are called by UINavigationController.
Finally i solved the problem and placed a close button on the login view. and on tab of this button i closed the login web view
