javascript - How to fix: TypeError: 'null' is not an object (evaluating 'event.relatedTarget.parentNode') -


this came error after uploaded website i'm working on.

typeerror: 'null' not object (evaluating 'event.relatedtarget.parentnode')

any ideas on how fix this/ should replace with?

without other context, if event.relatedtarget.parentnode giving error means either event, or event.relatedtarget null.

so:

if (event && event.relatedtarget && event.relatedtarget.parentnode) {     // code here }

now how should handle case event or event.relatedtarget null? have no idea because haven't given enough information have idea doing.

what need figure out why it's (or maybe time) null.
