ASP.NET MVC4 Razor模板简易分页效果
一、无数据提交 第一步,建立一个 Controller命名为PageIndex的空控制器,自定义一个方法如下: public ActionResult PageIndex(string action,string controller,int currentPage,int pageCount) { //int count = db.Product.Count(); ViewBag.PageCount = pageCount;//从操作中获取总数据页数将传入分页视图页面 ViewBag.CurrentPage = currentPage;//从操作中获取当前页数将传入分页视图页面 ViewBag.action = action; ViewBag.controller = controller; return PartialView(); } 传入四个参数: action:操作(要分页的视图的操作,默认为Index); controller:控制器; currentPage:当前页数; pageCount:数据总页数 第二步:添加视图(PageIndex) @if (ViewBag.PageCount == null || ViewBag.PageCount == 0) { <span>您好,当前没有数据显示!</span> } else { if (ViewBag.CurrentPage <= 10) { <span><a href="@Url.Action(ViewBag.action,ViewBag.controller,new { PageIndex = 1 },null)"> 首页</a>|</span> } else { <a href="@Url.Action(ViewBag.action,null)"> 首页</a> <span><a href="@Url.Action(ViewBag.action,new { PageIndex = ViewBag.CurrentPage - 10 },null)"> ...</a> </span> } for (int i = ViewBag.CurrentPage - 3; i < ViewBag.CurrentPage + 3; i++) { if (i <= 0) { continue; } if (i > ViewBag.PageCount) { break; } <span><a href="@Url.Action(ViewBag.action,new { PageIndex = i },null)"> 第 @i 页</a>|</span> } if (ViewBag.CurrentPage > 1) { <span><a href="@Url.Action(ViewBag.action,new { PageIndex = ViewBag.CurrentPage - 1 },null)"> 上一页</a>|</span> } if (ViewBag.PageCount > ViewBag.CurrentPage) { <span><a href="@Url.Action(ViewBag.action,new { PageIndex = ViewBag.CurrentPage + 1 },null)"> 下一页</a></span> } if (ViewBag.CurrentPage == ViewBag.PageCount || ViewBag.CurrentPage >= ViewBag.PageCount - 10) { <a href="@Url.Action(ViewBag.action,new { PageIndex = ViewBag.PageCount },null)"> 尾 页</a> } else { <span><a href="@Url.Action(ViewBag.action,new { PageIndex = ViewBag.CurrentPage + 10 },null)"> ...</a></span> <a href="@Url.Action(ViewBag.action,null)"> 尾 页</a> } <span style="padding-left: 20px">当前页数: @ViewBag.CurrentPage | 共 @ViewBag.PageCount 页 </span> } 第三步:操作的视图的控制器修改 public ViewResult Index(int? pageIndex) { int pageInd = pageIndex.HasValue ? pageIndex.Value : 1; ViewBag.PageCount = (int)Math.Ceiling(result.Count() / 20.0); //这里的是take,按照每页20个显示 return View(result.OrderBy(t => t.PID).Skip((pageInd - 1) * 20).Take(20)); } 第四步:页面调用(即最后一步) 复制代码 代码如下:@Html.Action("PageIndex","Product",new { action = "Index",controller = "Log",pageCount = ViewBag.PageCount,currentPage = ViewBag.CurrentPage }) 一般来说,数据都是变动的。 二、有数据提交 第一步:建立一个 Controller命名为PageIndex的空控制器,自定义一个方法如下: public ActionResult PageIndexKey(int currentPage,int pageCount) { ViewBag.PageCount = pageCount;//从操作中获取总数据页数将传入分页视图页面 ViewBag.CurrentPage = currentPage;//从操作中获取当前页数将传入分页视图页面 return PartialView(); } 第二步:建立分布视图 <script> $(function () { $("#pageingByForm a").click(function (event) { $("#pageIndex").val($(this).attr("pageIndex")); //$(this).parent("Form").submit(); document.getElementsByTagName("Form").item(0).submit(); event.preventDefault(); }); }); </script> @Html.Hidden("pageIndex") <div id="pageingByForm"> @if (ViewBag.PageCount == null || ViewBag.PageCount == 0) { <span>当前没有数据</span> } else { if (ViewBag.CurrentPage <= 10) { <span><a pageindex="1" href="#">首页</a>|</span> } else { <span><a pageindex="1" href="#">首页</a>|</span> <span><a pageIndex="@(ViewBag.CurrentPage - 10)" href="#">...</a>|</span> } for (int i = ViewBag.CurrentPage - 3; i < ViewBag.CurrentPage + 3; i++) { if (i <= 0) { continue; } if (i > ViewBag.PageCount) { break; } <span><a pageIndex="@i" href="#">第 @i 页</a>|</span> } if (ViewBag.CurrentPage >1) { <span><a pageIndex="@(ViewBag.CurrentPage - 1)" href="#">上一页</a>|</span> } if (ViewBag.PageCount > ViewBag.CurrentPage) { <span><a pageIndex="@(ViewBag.CurrentPage + 1)" href="#">下一页</a></span> } if (ViewBag.CurrentPage >= ViewBag.PageCount - 10) { } else { <span><a pageIndex="@(ViewBag.CurrentPage + 10)" href="#">...</a>|</span> <span><a pageIndex="@ViewBag.PageCount" href="#">尾 页</a></span> } <span style="padding-left: 20px">当前页数: @ViewBag.CurrentPage | 共 @ViewBag.PageCount 页 </span> } </div> 第三步:修改操作视图和控制器 public ViewResult Index(int? pageIndex,string search) { int pageInd = pageIndex.HasValue ? pageIndex.Value : 1; ViewBag.PageCount = (int)Math.Ceiling(result.Count() / 20.0); return View(result.OrderBy(t => t.PID).Skip((pageInd - 1) * 20).Take(20)); } 视图(页面调用): 根据性别得到查询结果 性别: @Html.TextBox("sex") <input type="submit" value="查询" /> @Html.Action("PageIndexKey","PageIndex",new { pageCount = ViewBag.PageCount,currentPage = ViewBag.CurrentPage }) Example: //数据,一个list的集合 List<string> s = new List<string>(); s.Add("张军"); ViewBag.PageCount = (int)Math.Ceiling(s.Count() / 20.0); return View(s.Skip((pageInd - 1) * 20).Take(20)); @Html.Action("PageIndex", new { action = "",controller = "",currentPage = ViewBag.CurrentPage }) 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持编程小技巧。 您可能感兴趣的文章:
