Hi,

When I use multiple iframe in my web page with pNotify and do submit or a button click in the page, I am getting error "Uncaught TypeError: Cannot read property 'opener' of undefined" in at PNotify.position (pnotify.js:641).

I am getting this error when I am changing a iframe src in a text box change event and do submit the page. This is happening only in Chrome browser. Please help me to solve this issue. error

Many thanks!

研究方向: The error occurs at pnotify.js line 641 in the PNotify.position method when accessing window.opener inside iframes. Investigate whether window.opener is null/undefined in cross origin iframe contexts. A common fix is to check if window.opener exists before accessing its properties. The repository is stale with no recent activity, so any fix would need to be proposed in a new PR.
