How to adapt to the new jquery?

Question

JavaScript

Good afternoon or evening, I decided to put a chat and a couple of scripts, but I ran into a problem that the chat does not scroll down, namely, part of the script does not work.
The script works on version jquery 2.1.1
And it is necessary on version 1.9.1 and above

the script itself - jsfiddle.net/fod07w4f

Many thanks in advance

Код предложить не могу, но можно поставить две версии jQuery - одну как $, а на ваш код навесить jQuery. Две версии одновременно, в общем
