Ajax–調用PageMethod

PageMethods:

    using System.Web.Services;    [WebMethod]    public static string Ok()    {        return "this is function ok!";    }

注意:using及WebMethod

 

ScriptManager:

    <asp:ScriptManager ID="sm" runat="server" EnablePageMethods="true" >    </asp:ScriptManager>

注意:EnablePageMethods="true",否則無法啟用PageMethod

 

Js:

    <script type="text/javascript">        function btn_click(){            PageMethods.Ok(onSuccessed);        }                function onSuccessed(result){                $get("result").innerHTML=result;        }    </script>

 

結果:
