MVC异步分页代码分享 

1、控制器代码 

// // GET: /AjaxUser/ shopEntities shop = new shopEntities(); public ActionResult Index() { return View(); } public ActionResult loadjson() { int pageSize = Request["pageSize"] == null ? 10 : int.Parse(Request["pageSize"]); int pageIndex = Request["pageIndex"] == null ? 1 : int.Parse(Request["pageIndex"]); int totalCount = shop.tbl_admin.Count(); //给前台userinfo所有的数据，并且是json格式 var allorder = shop.tbl_admin.OrderBy(u=>u.id) .Skip(pageSize*(pageIndex-1)) .Take(pageSize) .ToList(); //接受一个对像，内部把此对象使用javaScript序列化类对象志字符串，发送到前台 var data = from u in allorder select new { u.id,u.realname,u.sex}; string strNav = PageNavHelper.ShowPageNavigate(pageIndex,pageSize,totalCount); var result = new {Data=data, NavStr=strNav }; return Json(result, JsonRequestBehavior.AllowGet); }

2、Html代码 

@{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Index</title> <link href="~/Content/NavPage.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.8.2.min.js"></script> <script src="~/Scripts/jquery-ui-1.8.24.js"></script> <script src="~/Scripts/jquery.easyui.min.js"></script> <script src="~/Scripts/jquery.unobtrusive-ajax.js"></script> <script src="~/Scripts/jquery.validate.unobtrusive.js"></script> <script type="text/javascript"> $(function () { //页面加载完成后从后如加载当前页数据 initTable(); }); //初始化表格数据 function initTable(queryData) { $.getJSON("/AjaxUser/loadjson",queryData, function (data) { var tb = $("#tbList"); //先移除旧的，添加新的 $("#tbList tr[type=data]").remove(); for (var i = 0; i < data.Data.length; i++) { var strTr = "<tr type='data'>"; strTr += "<td>" + data.Data[i].id + "</td>"; strTr += "<td>" + data.Data[i].realname + "</td>"; strTr += "<td>" + data.Data[i].sex + "</td>"; strTr += "<td><a UId='" + data.Data[i].id + "' href='javascript:void(0)'>修改</a>" + "<a UId='" + data.Data[i].ID + "' href='javascript:void(0)'>删除</a></td>"; strTr += "</tr>"; tb.append(strTr); } $("#Nav").html(data.NavStr); //绑定分页标签的点击事件 $(".pageLink").click(function () { //把页码弹出来 var strHref = $(this).attr("href"); var queryStr = strHref.substr(strHref.indexOf('?') + 1); //alert(queryStr); initTable(queryStr); return false; }); }); } </script> </head> <body> <div> <table> <tr> <td>id</td> <td>姓名</td> <td>性别</td> <td>操作</td> </tr> </table> <div class="paginator"> </div> </div> </body> </html>

3、分页类

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web; namespace MvcTest4.Models { public class PageNavHelper { //主要就是输出分页的超级链接的标签 //自定义分页Helper扩展 public static string ShowPageNavigate(int currentPage, int pageSize, int totalCount) { var redirectTo = HttpContext.Current.Request.Url.AbsolutePath; pageSize = pageSize <= 0 ? 3 : pageSize; var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数 var output = new StringBuilder(); if (totalPages > 1) { //if (currentPage != 1) {//处理首页连接 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex=1&pageSize={1}'>首页</a> ", redirectTo, pageSize); } if (currentPage > 1) {//处理上一页的连接 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>上一页</a> ", redirectTo, currentPage - 1, pageSize); } else { // output.Append("<span class='pageLink'>上一页</span>"); } output.Append(" "); int currint = 5; for (int i = 0; i <= 10; i++) {//一共最多显示10个页码，前面5个，后面5个 if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages) { if (currint == i) {//当前页处理 //output.Append(string.Format("[{0}]", currentPage)); output.AppendFormat("<a class='cpb' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage, pageSize, currentPage); } else {//一般页处理 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage + i - currint, pageSize, currentPage + i - currint); } } output.Append(" "); } if (currentPage < totalPages) {//处理下一页的链接 output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>下一页</a> ", redirectTo, currentPage + 1, pageSize); } else { //output.Append("<span class='pageLink'>下一页</span>"); } output.Append(" "); if (currentPage != totalPages) { output.AppendFormat("<a class='pageLink' href='{0}?pageIndex={1}&pageSize={2}'>末页</a> ", redirectTo, totalPages, pageSize); } output.Append(" "); } output.AppendFormat("第{0}页 / 共{1}页", currentPage, totalPages);//这个统计加不加都行 return output.ToString(); } } }

4、分页CSS 

body { } .paginator { font: 12px Arial, Helvetica, sans-serif; padding: 10px 20px 10px 0; margin: 0px; } .paginator a { border: solid 1px #ccc; color: #0063dc; cursor: pointer; text-decoration: none; } .paginator a:visited { padding: 1px 6px; border: solid 1px #ddd; background: #fff; text-decoration: none; } .paginator .cpb { border: 1px solid #F50; font-weight: 700; color: #F50; background-color: #ffeee5; } .paginator a:hover { border: solid 1px #F50; color: #f60; text-decoration: none; } .paginator a, .paginator a:visited, .paginator .cpb, .paginator a:hover { float: left; height: 16px; line-height: 16px; min-width: 10px; _width: 10px; margin-right: 5px; text-align: center; white-space: nowrap; font-size: 12px; font-family: Arial,SimSun; padding: 0 3px; }
