     var source= document.getElementById("ddlFromCity").value;
     var desti = document.getElementById("ddlToCity").value;
     if(Category != "" && Category != null)

The method getFairChart(String, String, String, String, String, String, String, String, String, String) in the type Values is not applicable for the arguments (String, String, String, String, String, void, String, void, String, void)

Java is already executed at the server side before the response arrives to the client and Javascript (which is an entirely different language) can only be executed at the client side if the response is already arrived at the client side.
If you want to execute some Java using Javascript, you'll have to create a new request to the server. That can be a GET request or a POST request. You can use plain vanilla links, or forms or AJAX for that.
