It's one of those things that can't be done with the current browsers.
If you were setting up a stand-alone browser on a computer in the foyer of your local museum (for example) then you could put the browser into kiosk mode (that forces the page to full screen with no window chrome).
I bet you aren't, though. Sorry![[smile]](/data/assets/smilies/smile.gif "[smile] [smile]")

There is no way, using JavaScript, to categorically stop the user from navigating back and forth successfully in all modern browsers.
Much like trying to hide source or stop images from being stolen: give up while you're ahead!

... and be aware that I can right-click (in the windows world) and go back... and I can use command-left bracket (and right bracket) in the Mac world (for Safari at least)...
Just to say that if your web application relies on the user being never using the back/forward buttons... then it is going to be tricky to get a robust solution. It may be better to find a method to gracefully fail -- the users will learn quickly
I would imagine that a simple pop-up (as suggested) would suit for most of the people most of the time. And that's probably not a bad target.

Why would you want to? So they don't see old data? Instead of trying to disable the back button, you should disable the browser's cache. That way, when the user clicks the back button a new request will be made to the server and the latest data from your datasource can be displayed to the user.

I want to disable BACK so they see old data ... it's the contrary lol.
Imagine, you chat with someone and here is the conversation history, that you see on the web page:
- Hi, what's up?
- I'm fine, what about you ?
- Not much ...
Now, you press one time BACK, you obtain:
- Hi, what's up?
- I'm fine, what about you ?
You press a second time BACK, you obtain:
- Hi, what's up?
You press a third time BACK, you obtain: ... nothing ...
And you know that the principle of the chat is to keep the history in a kind of textarea with horizontal scrollbar. I don't want the user to be able to remove the history. It's the same in Messenger, AIM ...
I'm gonna work on your piece of code now.
Thanks to you !
