jQuery.event.props is undefined

There is an issue with jquery version 3 or above as mentioned in the jquery.event.move github issue page:

jQuery 3.0.0 breaks jQuery.event.props usage

This happened since in jQuery 3.0.0 upgrade jQuery.event.props and jQuery.event.fixHooks are removed. More details here:

Breaking change: jQuery.event.props and jQuery.event.fixHooks removed

jQuery's event handling performance increased thanks to a reorganization of event property management. The main improvement is that jQuery now only calculates or copies a property on the first access, rather than calculating and copying them up front. This is a really big win with properties that may force layout that the event handler may not even need. The most common use we know of was to add properties for pointer events, which is no longer necessary because those events are supported already in jQuery 3.0. The jQuery Migrate plugin provides support for these properties if you still need them. The related but undocumented mouseHooks and keyHooks lists were removed as well. The team is interested in understanding other use cases before defining new APIs, so feel free to open a ticket.

The github issue is still open and no solution has been provided yet as of 08.01.2016. As an alternative fix you can either:-

• Use the jQuery Migrate plugin, which provides support for these properties.
• Or, use any jQuery version below 3.0.0
