Get linkage with JavaScript

<script>//Linkage Query $ (function () {$ ("#BranchName"). Change (function () {var pa                Rent = $ ("#BranchName option:selected"). Val (); if (parent = "" && parent!=0) {$.ajax ({url: "/store/getstore?branch Id= "+ $ (" #BranchName option:selected "). Val (), type:" Get ", Success:functio N (data) {if (data).                                Data.length > 0) {var op = ""; for (var i = 0; i < data. Data.length; i++) {op + = "<option value=" + data. Data[i]. Id + ">" + data. Data[i].                                                            Dealername + "</option>"} $ ("#DealerName"). HTML (OP); } if (data. Data = = "") {var option = "<option></option>" $ ("#DealerName"). HTML (option);                }                            }                    });                    } else {eqlee.showwarring ("Please select a branch and reseller");                $ ("#DealerName"). HTML ("<option> please select </option>");        }            });    }); </script>

　　

Above is the implementation of the linkage script

        Public Jsonresult GetStore (Guid branchid)        {            var data = new Models.returnjson () {Error = false};            var filter = string. Format ("Deleted = 0 and Branchid = ' {0} '", Branchid);            var Dealermodel = _blldealer.list (where:filter);            var id = dealermodel.select (x = x.id);            var dealername = dealermodel.select (x = x.dealername);            data = new Models.returnjson () {Error = false, data = Dealermodel};            return jsonnet (data, behavior:JsonRequestBehavior.AllowGet);        }

The above is the way to get linkage in the background

The above is the method to get linkage, because there is no time to write, only simple point.
