在外部窗口的新窗口（window.open）中的onclose / onunload

Question

Is there any way to capture the event onclose of the window? I am trying to auth the user on twitter with a popup. And I would like to reject the request/promise if the user close the window.

The problem is onclose does not exists and onunload works on urls of the same domain. I have tried an iframe, but twitter do not allow that.

No., There is no event for capturing window close event.

Try using window.unload(function(){}) in the current page.

above event triggered while refreshing the page or navigating from the current page.
