window.onunload is not working in Samsung Galaxy Tab browser

Question

In my application clicking on a link a child window opens, now when I close the parent window I need to capture window.onunload event of parent window so that I can close child window.

This is working fine in desktop browsers, but not in Samsung Galaxy Tab in built browser.

Can anybody help me on that?

Answer 1

You need to check if window.unload is even supported on that browser. You might want to look at using div overlays instead which you can control.

Answer 2

Due to inconsistencies in browser support, you might consider redundant mechanisms using a shotgun approach:

• Trap the parent window's hide, unload, and beforeunload events and close the child window. Trap ALL of them! One of them is bound to work.

• Write a timer in the child window that polls/checks for window.opener and closes itself if the parent no longer exists

Answer 3

The onbeforeunload function isn't implemented by H browser, instead use:

window.onHide callback function
