my controller code

public actionresult waitinglist()         {             sytentities ca = new sytentities();             viewbag.categoryid = new selectlist(ca.businesscategories.tolist(), "categoryid", "categoryname");             viewbag.service = new selectlist(ca.tblbusinesscategories.tolist(), "businessid", "businessname");             return view();         }   public jsonresult categories(int id)         {             sytentities db = new sytentities();             var business = s in db.tblbusinesscategories                            s.categoryid == id                            select s;             return json(new selectlist(business.toarray(),"businessid", "businessname"), jsonrequestbehavior.allowget);         }   public jsonresult location(int id)         {               sytentities db = new sytentities();             var location = s in db.tblbusinesslocations                            s.businessid == id                             join loc in db.tbllocations                             on s.locid equals loc.locationid                            select loc;                return json(new selectlist(location.toarray(), "locationid", "locationname"), jsonrequestbehavior.allowget);          }         public jsonresult employee(int id)         {              sytentities db = new sytentities();             var emp = s in db.employees                       s.locationid == id && s.businessid == 91                       select s;             return json(new selectlist(emp.toarray(), "empid", "empname"), jsonrequestbehavior.allowget);         } 

in public jsonresult employee(int id) need pass ('#service') value. possible do? can please me?

you can pass many values want using data parameter of jquery.getjson

var url = '@url.action("categories", "appt")'; // don't hard code urls! $.getjson(url, { id: $('#business').val(), otherproperty: anothervalue }, function (data) {
