PageMethods

主要是用到ScriptManger,老知识Mark一下,ScriptManager要EnablePageMethods="true"

后台

using System.Web.Script.Services;
using System.Web.Services;
[WebMethod] [ScriptMethod] public static string GetValue(string userID) { return userID+DateTime.Now.ToString(); }

 

前台

<head runat="server">

    <title>无标题页</title>

 



    <script language="javascript" type="text/javascript">

        function CheckUserID() {

            PageMethods.GetValue('Anson', function(result) {

                alert(result);

            });

        }

    </script>



</head>

<body>

    <form id="form1" runat="server"> 

     <asp:ScriptManager runat="server" EnablePageMethods="true">

    </asp:ScriptManager>

    <div>

        <input type="button" value="Test" onclick="CheckUserID();return false;" />

    </div>

    </form>

</body>
