本文章是利用jquery的ajax调用webservice返回json数组哦，json数据是网页特效的一种小型轻型数据，实时交互性更强于xml哦。

json数据

{"employee":[{"name":"john","sex":"man","age":"25"},{"name":"tom","sex":"man","age":"21"},{"name":"mary","sex":"woman","age":"21"}]}

  //jquery 调用webservice导入数据
            function loaddata() {
                var studentdata = collectiondata();
                $.ajax({
                    url: "importdataservice.asmx/importstu",
                    type: "post",
                    contenttype: "application/json;charset=utf-8",
                    datatype: "json",
                    data: "{"students":[{"name":"kobe ","sex":"boy","age":"20"},{"name":"mary","sex":"girl","age":"19"}]}",
                    success: function(result) {
                        alert(result.d);
                    },
                    error: function(e) {
                        alert(e.responsetext);
                    }
                });
            }
