jquery, encodeurlcomponent

Below jquery ajax is working fine. What I want to do is below:
url: GetModelListJSon + encodeURIComponent("(011,115217)"),

I want to be
var customerNo = "111";
var companyNo = "222";
and I got error alert in Chrome saying below:

XMLHttpRequest cannot load http://clientaccesstest.abc.com/wcf/orders/RestService/QuoteServiceJVC/GeModelList(.....)?_=1428433644469. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:62937' is therefore not allowed access.

The web service is working fine without cross domain issue. When I hard code like below, it works fine. Any ideas how to fix it?


url: GetModelListJSon + encodeURIComponent("(customerNo,companyNo)"),



function GetModelList(divisCode)
      var customerNo = "315217";            
        var GetModelListJSon = "http://clientaccesstest.abc/GetModel";            
        $(document).ready(function () {
            $.ajax({
              crossDomain: true,
                cache: false,
                type: "GET",
                async: false,
                dataType: "json",
                contentType: 'text/plain',
                url: GetModelListJSon + encodeURIComponent("(011,115217)"),
                success: function (data) {
                    $('#data').html(data);
                    if (data == null)
                        return;
                    resultObj = jQuery.parseJSON(data);
                    if (resultObj.Status != 'Failed') {
                        $('#json').html(setModelInfo(resultObj.Data,divisCode));
                    }
                },
                error: function (xhr,status,error) {
                    $('#data').html(xhr.responseText);
                    alert(xhr.responseText + " : error GetModelListJSon");
alert(status);
alert(error);
                }
            });
        });
}
