MVC HtmlHelper扩展类PagingHelper实现分页功能,供大家参考,具体内容如下
using System; using System.Collections.Generic; using System.Collections.Specialized; using System.Linq; using System.Text; using System.Web; using System.Web.Mvc; using System.Web.Routing; namespace HtmlHelperMvc.Models { /// <summary> /// 分页类如果一个页面显示两个列表只需要复制该类到项目中重命名一个就可以 /// </summary> public static class PagingHelper { #region 属性Property /// <summary> /// 当前页码 /// </summary> private static int".class值").live("click", function () { /// var page = $(this).attr("pagingParamName值"); /// $("#order").html("").load("/Customer/Order"+page); /// });live自动给遍历增加事件 /// </summary> /// <param name="html"></param> /// <param name="htmlAttributes">new {@class="grey",pagingParamName="page",href="/Admin/Product/Index" rel="external nofollow" } pagingParamName默认page,匿名类添加控件属性</param> /// <returns></returns> public static MvcHtmlString Paging(this System.Web.Mvc.HtmlHelper html, object htmlAttributes) { RouteValueDictionary values = new RouteValueDictionary(htmlAttributes); #region 属性赋值 if (values["href"] != null) { PagingUrl = values["href"].ToString(); } if (values["pagingParamName"] != null) { PagingParamName = values["pagingParamName"].ToString(); values.Remove("pagingParamName"); } else { PagingParamName = "page"; } #endregion #region 分页最外层div/span TagBuilder builder = new TagBuilder("div");//span //创建Id,注意要先设置IdAttributeDotReplacement属性后再执行GenerateId方法. //builder.IdAttributeDotReplacement = "_"; //builder.GenerateId(id); //builder.AddCssClass(""); //builder.MergeAttributes(values); builder.InnerHtml = PagingBuilder(values); #endregion return MvcHtmlString.Create(builder.ToString(TagRenderMode.Normal));//解决直接显示html标记 } private static string PagingBuilder(RouteValueDictionary values) { #region 条件搜索时包括其他参数 StringBuilder urlParameter = new StringBuilder(); NameValueCollection collection = HttpContext.Current.Request.QueryString; string[] keys = collection.AllKeys; for (int i = 0; i < keys.Length; i++) { if (keys[i].ToLower() != "page") { urlParameter.AppendFormat("&{0}={1}", keys[i], collection[keys[i]]); } } #endregion //CurrentPage = Convert.ToInt32(HttpContext.Current.Request.QueryString["page"] "0"); StringBuilder sb = new StringBuilder(); #region 分页统计 sb.AppendFormat("Total {0} Records Page {1} of {2} ", TotalCount, CurrentPage, TotalPages); #endregion #region 首页 上一页 sb.AppendFormat(TagBuilder(values, 1, " First")); //sb.AppendFormat("<a href={0}",url,urlParameter); if (HasPreviousPage) { sb.AppendFormat(TagBuilder(values, CurrentPage - 1, " Prev ")); //sb.AppendFormat("<a href={0}", url, CurrentPage - 1, urlParameter); } #endregion #region 分页逻辑 if (TotalPages > 10) { if ((CurrentPage + 5) < TotalPages) { if (CurrentPage > 5) { for (int i = CurrentPage - 5; i <= CurrentPage + 5; i++) { sb.Append(TagBuilder(values, i, i.ToString())); } } else { for (int i = 1; i <= 10; i++) { sb.Append(TagBuilder(values, i, i.ToString())); } } sb.Append("...

后台Controller代码
// // GET: /Home/ public ActionResult Index(int"htmlcode">@{ ViewBag.Title = "Index"; } @using HtmlHelperMvc.Models; <h2>Index</h2> <hr /> <style type="text/css"> #on { color: #FFF; background-color: #337AB7; border-color: #337AB7; } .pagination a { margin-right: 3px; padding: 5px 10px; font-size: 12px; text-decoration: none; background-color: #fff; border: 1px solid #ddd; cursor: pointer; display: inline-block; border-radius: 3px; } a { color: #337ab7; text-decoration: none; } a { background-color: transparent; } * { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; } </style> <script src="/UploadFiles/2021-04-02/jquery-1.8.2.js">最终效果图:
