本文實例講述了ASP.NET利用后臺實現直接生成html分頁的方法,是一個比較實用的功能。分享給大家供大家參考之用。具體方法如下:
1.建立存儲過程:
ALTER procedure [dbo].[p_news_query]@Page intasbeginselect top 5 new_id,new_title,new_url,new_content_text,create_time,user_name from (select *,ROW_NUMBER() over(order by new_id desc ) as RowNumber from (select new_id,new_title,new_url,new_content_text, dbo.f_ConvertDate(a.create_time) create_time, b.user_name from xs_new a left join xs_users b on b.user_no=a.create_user)TI ) A where A.RowNumber>(@Page-1)*5end
目前實驗的是每頁5條數據,傳入當前頁碼就可以了
2.前臺定義一個div ,用于顯示
<div id="divPage" runat="server" class="divpage"> </div>
3.后臺根據傳入參數來拼html
目前是模仿博客園的模式,前后顯示5條,多余的加...后到最后一條。具體代碼如下:
StringBuilder sbr = new StringBuilder(); int ITotalCount = pageLogic.QueryNewsCount(); int IPage = 1; if (Request["p"] != null) { IPage = Convert.ToInt32(Request["p"]); } int IPageCount = 5; int ITotalPage = ITotalCount / IPageCount; if (ITotalCount % IPageCount > 0) { ITotalPage += 1; } if (IPage != 1) { sbr.Append("<a href=/"news.ASPx?p=" + (IPage - 1).ToString() + "/"></a>"); } if (ITotalPage <= 10) { for (int i = 1; i <= ITotalPage; i++) { if (i == IPage) { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); } } } else { if (IPage - 5 > 2 && IPage + 7 < ITotalPage)//前后都有的 { sbr.Append("<a href=/"news.ASPx?p=1/">1</a>..."); for (int i = IPage - 5; i <= IPage + 5; i++) { if (i == IPage) { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); } } sbr.Append("...<a href=/"news.ASPx?p=" + ITotalPage.ToString() + "/">" + ITotalPage.ToString() + "</a>"); } else if (IPage - 5 <= 2)//前面不夠,后面有多余 { for (int i = 1; i <= 10; i++) { if (i == IPage) { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); } } sbr.Append("...<a href=/"news.ASPx?p=" + ITotalPage.ToString() + "/">" + ITotalPage.ToString() + "</a>"); } else if (IPage + 7 >= ITotalPage)//前面多余,后面不足 { sbr.Append("<a href=/"news.ASPx?p=1/">1</a>..."); for (int i = ITotalPage - 10; i <= ITotalPage; i++) { if (i == IPage) { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); } } } } if (IPage != ITotalPage) { sbr.Append("<a href=/"news.ASPx?p=" + (IPage + 1).ToString() + "/"></a>"); } divPage.InnerHtml = sbr.ToString(); rptNews.DataSource = pageLogic.QueryNews(IPage); rptNews.DataBind();
4.測試效果如下圖所示:
