分页技术html控制每页显示,自动化分页，HTML代码控制 思想_html/css_WEB-ITnose

1、绑定分页数据

Request：主要是获取当前查询中所参与的所有条件

pageSize：分页显示数量

totalCount：分页总数

currentPageStr：自定义参数(后面会更新该参数的用法和途径)

tab：自定义参数(后面会更新该参数的用法和途径，和上面currentPageStr配合使用，需优化)

pageIndexNumber：页面上显示当前页前、后多少页数数的数字

如：显示当前页前后个5页的数字

IsShouCount：是否显示总数量

2、用法，Response.Write页面输出一段html

3、源代码 方法主要用到请求头类的使用，HttpRequest

public static class ZCJExtensions{ /// /// 分页Pager显示(分页请求字符串默认为pi) /// /// 每页记录的数量 /// 总记录数 /// 显示页索引的数量 /// public static string Pager(int pageSize, int totalCount,int pageIndexNumber = 10) { return ZCJExtensions.Pager(HttpContext.Current.Request, pageSize, totalCount, "pi", "", pageIndexNumber); } /// /// 分页Pager显示 /// /// 请求 /// 每页记录的数量 /// 总记录数 /// 请求字符串 /// 切换ID /// 显示页索引的数量 /// public static string Pager(HttpRequest requ, int pageSize, int totalCount, string currentPageStr = "1",string tab="",int pageIndexNumber = 10,bool IsShouCount=false) { //var queryString = html.ViewContext.HttpContext.Request.QueryString; string html = ""; var queryString = requ.QueryString; int currentPage = 1; //当前页 var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数 //var dict = new System.Web.Routing.RouteValueDictionary(html.ViewContext.RouteData.Values); var dict = new System.Web.Routing.RouteValueDictionary(requ.Form); var output = new System.Text.StringBuilder(); var url = requ.Url.AbsolutePath + "?" + currentPageStr + "=(*)"; if (tab.Length > 0) { url += "&tab=" + tab; } //与相应的QueryString绑定 foreach (string key in queryString.Keys) { if (!string.IsNullOrEmpty(key) && queryString[key] != null ) { dict[key] = queryString[key]; if (key != currentPageStr && key.ToLower()!="tab") { url += "&" + key + "=" + queryString[key]; } } } //获取 ～/Page/{page number} 的页号参数 int.TryParse((dict[currentPageStr] != null) ? dict[currentPageStr].ToString() : "0", out currentPage); if (currentPage <= 0) currentPage = 1; if (totalPages > 1) { if (currentPage != 1) { dict[currentPageStr] = 1; //output.AppendFormat("{0} ", html.RouteLink(" 1) { //处理上一页的连接 dict[currentPageStr] = currentPage - 1; var pageunm = (currentPage - 1).ToString(); var tempurl = url.Replace("(*)", pageunm); //output.Append(html.RouteLink("上一页"); } else { //output.Append("= 1 && (currentPage + i - currint) <= totalPages) if (currint == i) { //当前页处理 output.Append(string.Format("{0}", currentPage)); } else { //一般页处理 dict[currentPageStr] = currentPage + i - currint; var pageunm = (currentPage + i - currint).ToString(); var tempurl = url.Replace("(*)", pageunm); //output.Append(html.RouteLink((currentPage + i - currint).ToString(), dict)); output.Append("" + pageunm + ""); } output.Append(""); } if (currentPage < totalPages) { //处理下一页的链接 dict[currentPageStr] = currentPage + 1; var pageunm = (currentPage + 1).ToString(); //output.Append(html.RouteLink(">", dict)); var tempurl = url.Replace("(*)", pageunm); output.Append("下一页"); } else { //output.Append(">"); } output.Append(""); if (currentPage != totalPages) { dict[currentPageStr] = totalPages; var pageunm = totalPages.ToString(); var tempurl = url.Replace("(*)", pageunm); //output.Append(html.RouteLink(">>", dict)); output.Append("尾页"); } output.Append(" "); } output.AppendFormat("第{0}页/共{1}页", currentPage, totalPages);//这个统计加不加都行 if (IsShouCount == true) { output.AppendFormat("，共{0}条记录", totalCount); } //HtmlString return output.ToString(); }}
