怎么在asp.net后臺中生成一個html分頁功能?相信很多沒有經(jīng)驗的人對此束手無策,為此本文總結(jié)了問題出現(xiàn)的原因和解決方法,通過這篇文章希望你能解決這個問題。
1.建立存儲過程:
ALTER procedure [dbo].[p_news_query] @Page int as begin select 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)*5 end
目前實驗的是每頁5條數(shù)據(jù),傳入當(dāng)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(jù)傳入?yún)?shù)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() + "\">上一頁</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() + "\">下一頁</a>"); } divPage.InnerHtml = sbr.ToString(); rptNews.DataSource = pageLogic.QueryNews(IPage); rptNews.DataBind();
