mui.ajax 调用 WEB Service 报错

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8848' is therefore not allowed access. The response had HTTP status code 500.

function getData() {
                var result = "";
                mui.ajax("http://mobile.china-crown.com:8088/Service.asmx/GetCustomerPageList", {
