我的目的是使用combobox加載ASHX文件的JSON，但不知道為什么總是加載不到數據。前臺代碼：?<script type="text/javascript" language="javascript" >??????? $(function () {??????????? $("#ddlGys").combobox({???????????? url: '/Common/Helper.ashx',???????????? mode:'remote',???????????? valueFild: 'gys',???????????? textFild:'gysbh'??????????? });??????? });??? </script> ?<select id="ddlGys"? class="easyui-combobox"? /> 后臺： ?public List<Supplier> GetSupplier()??????? {??????????? DataTable dt = GingKo.Code.GetDT("select top 20 gysbh,gys from wz_gys");??????????? List<Supplier> suppliers = new List<Supplier>();??????????? for (int i = 0; i < dt.Rows.Count; i++)??????????? {??????????????? Supplier tmp = new Supplier();??????????????? tmp.gys = dt.Rows[i]["gys"].ToString();??????????????? tmp.gysbh = Convert.ToInt32(dt.Rows[i]["gysbh"].ToString());??????????????? suppliers.Add(tmp);??????????? }??????????? return suppliers;??????? } ???? //該方法為combobox提供JSON ???? public string GetSuppliersJSON()??????? {??????????? JavaScriptSerializer serializer = new JavaScriptSerializer();??????????? Supplier s = new Supplier();??????????? List<Supplier> suppliers = s.GetAllSupplier();??????????? string json = serializer.Serialize(suppliers);??????????? return json;??????? }
