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>
