JQuery+Ajax无刷新分页的实例代码(2)

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                pageCount = new News().GetNewsCount();
            }
        }

四、最主要的是ajax处理程序：PagerHandler.ashx

复制代码 代码如下:

 public class PagerHandler : IHttpHandler
    {
        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            string str = string.Empty;
            int pageIndex = Convert.ToInt32(context.Request["pageIndex"]);
            int size = Convert.ToInt32(context.Request["pageSize"]);
            if (pageIndex == 0)
            {
                pageIndex = 1;
            }
            int count = 0;

News n = new News();
            List<News> list = n.GetNewsList(pageIndex, size, ref count);
            StringBuilder sb = new StringBuilder();
            foreach (News p in list)
            {
                sb.Append("<tr><td>");
                sb.Append(p.News_id);
                sb.Append("</td><td>");
                sb.Append("<a href='#'>"+p.News_title+"</a>");
                sb.Append("</td><td>");
                sb.Append(p.News_time);
                sb.Append("</td><td>");
                sb.Append(p.News_readtimes);
                sb.Append("</td></tr>");
            }
            str = sb.ToString();
            context.Response.Write(str);
        }
