Asp.net Ajax提供PageMethods调用

页面上的Javascript通过ASP.NET AJAX除了可以调用Web服务类，还可以调用网页中的静态方法。

<%@ Page Language="C#" %>

<%@ Import Namespace="System.Web.Services" %>

<%@ Import Namespace="System.Web.Script.Services" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

    [WebMethod]

    [ScriptMethod(UseHttpGet = true)]

    public static string ServerTime()

    {

        return DateTime.Now.ToUniversalTime().ToString();

    }

</script>

<script type="text/javascript">

    function pageLoad() {

        $addHandler($get('timeButton'), 'click', getTime);

    }

    function getTime() {

        PageMethods.ServerTime(OnServerTimeComplete);

    }

    function OnServerTimeComplete(result, userContext, methodName) {

        alert(result);

    }

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title>ASP.NET AJAX PageMethod</title>

</head>

<body>

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

    <div>

        <asp:ScriptManager ID="ScriptManager1" runat="server"

            EnablePageMethods="true">

        </asp:ScriptManager>

        <div>

            <input type="button" value="Show Server Time" id="timeButton" />

        </div>

    </div>

    </form>

</body>

</html>
