If its on page JavaScript and it is pulling data from database dynamically, than this is bad. However, if the request is made and JavaScript is running on the server it will output data as a plain text. This is Good. Google is looking for content. So when you view source all you will see is text that server side script produced. Try to keep on page data clean and do data gathering on the server side. This will speed up the page load and improve user experience.
