JQuery实现Ajax 根据商品名称自动显示价格

SELECT  id, name, price  FROM  dbo.T_Product
where  name  =   @name

using  System;
using  System.Collections.Generic;
using  System.Linq;
using  System.Web;
using  AJAX.DataSetProductsTableAdapters;

namespace  AJAX
{
     ///   <summary>
     ///  GetPrice 的摘要说明
     ///   </summary>
     public   class  GetPrice : IHttpHandler
    {

         public   void  ProcessRequest(HttpContext context)
        {
            context.Response.ContentType  =   " text/plain " ;
             string  name  =  context.Request[ " name " ];

            var data  =   new  T_ProductTableAdapter().GetDataByName(name); //调用DataSet中的方法
             if  (data.Count  <=   0 )
            {
                context.Response.Write( " none|0 " );    // 竖线左边是返回状态，右边是价格
            }
             else
            {
                context.Response.Write( " ok| "   +  data.Single().price);  // 我们自己定义的协议格式 ok可以换成其他的字符串；
            }
        }

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