Instead of beforeunload use onbeforeunload

popupcsd.onbeforeunload = function(){
    console.log('leaving page');                    
    alert('alert');
    return leavingPageText;
}

I tried and its working on my end

popup window url is different doamin is `www.domain.com` and popup url is `www.example.com` – Tanveer Hussain Dec 19 '17 at 08:31
That should not make a difference. You can open any site using window.open – cdoshi Dec 19 '17 at 09:10

Callback name that you have used is wrong. It should be changed as below.

 popupcsd.onbeforeunload instead of popupcsd.beforeunload
