The event code you have already seems to work when I test it. You just need to return false to stop the browser from closing. The user will be asked if they’re sure they want to navigate away from the page.

I’m using this shortened version of your code:

window.onbeforeunload = confirmExit;
function confirmExit(){
    alert("confirm exit is being called");
    return false;
}
