使用Ajax.NET异步调用-优快云博客

一种异步调用方式，AJAX的一种实现方式.这种方式需要Ajax.NET Library的DLL文件Ajax.dll,可以从网上获得,我使用的是Version 5.6.3.4。示例如下: 页面代码如下:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html xmlns="http://www.w3.org/1999/xhtml " >
<head id="Head1" runat="server">
    <title>无标题页</title>
    <script type="text/javascript" language="javascript">
    function CallServer()
    {
        Test.RaiseBack(document.all.DataInput.value,GetCallbackData);
    }
    function GetCallbackData(response)
    {
        var result=(response.value == null ? "" : response.value);
        alert("服务器返回:/n" + result);
    }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input id="DataInput" />
        <button type="button" language="javascript" onclick="CallServer();">异步调用</button>
    </div>
    </form>
</body>
</html>

后台代码如下:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class Test : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Ajax.Utility.RegisterTypeForAjax(typeof(Test));
    }
    [Ajax.AjaxMethod]
    public string RaiseBack(string eventArgument)
    {
        return "Time:" + DateTime.Now.ToString() + "/nUpperData is:" + eventArgument.ToUpper();
    }
}
