How to fix not working hide() show() in select option?

Question

JavaScript

Here is the site . There are Door type and Style fields.
These are related selects. You choose something in the first and in the second only the necessary information. Everything is built on .change() in the first select and hide()\.show() for option in the second list.

Doesn't work in safari. I don't know how to rewrite the code to make it work.
