ExtJs對於Ajax的使用非常簡單，看下面的代碼:

1.Html頁：

<!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 >
     <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <link rel="stylesheet" type="text/css" href="js/ext2.2/resources/css/ext-all.css" />
     <script type="text/javascript" src="js/ext2.2/adapter/ext/ext-base.js"></script>
    <script type="text/javascript" src="js/ext2.2/ext-all.js"></script>
    <title></title>
</head>
<body>
<script type="text/javascript">
    Ext.onReady(function() {

Ext.get("btnTest").on("click", fnAjaxDemo);

})
</script>

        <input id="name" value="Jimmy" name="name" />
        <button id="btnTest">擷取服務端資訊</button>

</body>
</html>

2.服務端GetData.ashxusing System.Web;
using System.Web.Services;

namespace Ajax_WCF
{
    /// <summary>
    /// $codebehindclassname$ 的摘要說明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    public class GetData : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            if (context.Request["name"] != null && context.Request["name"].ToString()!="")
            {
                context.Response.Write("Hello World," + context.Request["name"].ToString() + "!");
            }
            else
            {
                context.Response.Write("Hello World");
            }
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}
