Javascript error: TypeError: 'null' is not an object (evaluating 'event.target') on safari

Question

I have difficulty on integrating my JavaScript syntax. My code is working on Internet Explorer (IE). However, I encountered a JavaScript error when running it on Safari.

Answer 1

According to MDN:

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Event.srcElement is a proprietary alias for the standard Event.target property. It is specific to old versions of Microsoft Internet Explorer.

So just avoid using event.srcElement instead you should use event.target.
