Typeerror: $.event.props is Undefined

Question

I have a slider like this for example: http://themes.audemedia.com/html/servereast/vps-slider-6-plans.html

In my case it is presenting the following error in the console when I click on the slide/drag button:

As you report this page on the official website, the property jQuery.event.props has been removed since jQuery version 3.0.0:

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 already supported in jQuery 3.0. The jQuery Migrate plugin provides support for These properties if you still need them.

So you have 2 alternatives:

1. Use an additional plugin called jQuery Migrate, supporting the property or,
2. Using a version earlier than 3.0.0 of jQuery.

Obs.: the page you mentioned uses jQuery v2.1.4, which can be checked at this link.
