Check if window popup close or not

Question

I am opening a youtube video on popup using javascript. I am using the following code

  var myWindow;
    $("#nextview").click(function() {

    var vidurl = 'www.youtube.com'; 
    myWindow = window.open(vidurl, "popupWindow", "width=600, height=400, scrollbars=yes");
    //counter(myWindow,refreshIntervalId);

});

Now I want to show message when user close this popup window.

What I Tried

myWindow.addEventListener("beforeunload", function(event) {
    event.returnValue = "Write something clever here..";
});

Getting error

Uncaught TypeError: Cannot read property 'addEventListener' of undefined

Your code seems to work just fine, check it here https://jsfiddle.net/s254e3bk/1/ — Carsten Løvbo Andersen, Sep 11 '17 at 05:54
Looks like `addEventListener` is called before `myWindow` is initialized. — maazadeeb, Sep 11 '17 at 05:55
@CarstenLøvboAndersen I want to check if user closing the window or not and do some functionality there — Azad Chouhan, Sep 11 '17 at 05:57
@azadchouhan If you run the code i provided, then it writes to the console log when the user closes the window. If that is not what you want please explain. — Carsten Løvbo Andersen, Sep 11 '17 at 05:58
@CarstenLøvboAndersen yes your answer is working. But with the same domain's popup window. In my case the popup window will open a youtube video from my another website. so the url of both windows will be different. this is my problem. What I have to do for it? — Azad Chouhan, Sep 11 '17 at 06:05

try this

var myWindow;
    $("#nextview").click(function() {

    var vidurl = 'www.youtube.com'; 
    myWindow = window.open(vidurl, "popupWindow", "width=600, height=400, scrollbars=yes");
    //counter(myWindow,refreshIntervalId);
    myWindow.onbeforeunload = function(){ 
       //some code like
       alert("closed");
}
});

this also can able to catch the window close.
