JQuery .net WebService 参数必须一致

$.ajax({
                type: "POST",
                contentType:"application/json; charset=utf-8",
                url: "/LearnJQuery/ajax1.asmx/response1",
               data:"{username:\""+$("#inputName").val()+"\"}",


上面的username必须和webservice中的一致.
今天终于感受到js调试的困难了.要小心小心啊.
