How to disable the browser back and forward button

[Rakuli]

Javascript isn't really intended to control the browser functionality, it is to enhance the page for the user.

There is no way to disable the back button with javascript it requires javascript tricks which personally I can't stand if a site does this to me -- I find a site on Google, have a quick look and try click back only to be on the same page again grr

The back button is dependent on the browser's history object:

Code: Select all

window.history

but the history object is not writable for security reasons. You have three methods that can navigate to any node along the history object:

Code: Select all

window.history.forward();
window.history.back();
window.history.go(value);

window.history.go(-1); //equivalent to .back();
window.history.go(1); //equivalent to .forward();

The go method can also specify a URL, but it's only in relation to the children of the history object, not a redirect.

The back and forward button functionality can be extended to operate on asynchronous server requests (either through local anchor points or asynchronous buffering techniques like iframe or ajax) but cannot and SHOULD NOT be disabled.

Don't. Users will hate you, and designers will sneer at you.

I agree, this sort of thing would make me angrily punch my keyboard .
