Is it possible to disable brower refresh capabilities with JavaScript?

The reason I ask such an odd question is that I currently am creating computer based test environment, and obviously in the test I have a live countdown timer. Unfortunately on refreshing the page the timer is reset :(.

Obviously I will be looking to involve some method of storing the start time server side so that it always starts the countdown from this. However in a test situation I want the user to be locked in essentially, so I want to know if I can disable the browser navigationg buttons like back and refresh.

Not much control here, but did you try onUnload event of JavaScript.

<body onUnload='SaveCounterData();'>

This event is supposed to execute, when the page is being unloaded. Why/How (back button/refresh/closing window) it is being unloaded is not important here.

No, you cant.

There are only some nasty ways involving an alert message that has to be confirmed (works in most browsers).

In a real environment you should work with some server side logging based on account/ip and/or cookies.

In a test environment you could give the user a specific browser without that funcitonality. Firefox offers that in form of prism.

Not unless you can give the user a browser which has had that functionality removed
