window.onload is recognised by the opera browser but onunload and onbeforeunload are not.
The javascript function is called on onload but not on onunload and onbeforeunload.

All other browsers are fine with this but except opera.

Please post an SSCCE (Short Self-Contained Correct Example) demonstrating the issue.
