" XMLHttpRequest cannot load http://shoperola.com/Restaurant/foodysrest/sample?{}. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://:8088' is therefore not allowed access".

Answer

you are trying to perform XMLHttpRequest(AJAX) to another domain.

This is restricted due to security reasons.
