When you send a request (parser.js) it should show my custom spinner. After loading the data the spinner shouldn't be visible. I have a div id="loader-wrapper" which I set visible or none.

1. I have a problem when I want to use this spinner on different sites because the id is the same. 

2. Setting the spinner visible and not visible doesn't work in the parser.js

Can someone help me?
