jquery的ajax調用Webservice返回Json數組

本文章是利用jquery的ajax調用webservice返回json數組哦，json資料是網頁特效的一種小型輕型資料，即時互動性更強於xml哦。

json資料

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

 

  //jquery 調用webservice匯入資料
            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);
                    }
                });
            }

                        student student = new student();

                        //為新構造的student對象屬性賦值。
                        foreach (string key in stu.keys)
