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, ViewBag.controller, new { PageIndex = 1 }, null)">首页</a><span><a href="@Url.Action(ViewBag.action, ViewBag.controller, 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, ViewBag.controller, new { PageIndex = i }, null)">第 @i 页</a>|</span>}if (ViewBag.CurrentPage > 1){<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage - 1 }, null)">上一页</a>|</span>}if (ViewBag.PageCount > ViewBag.CurrentPage){<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, 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, ViewBag.controller, new { PageIndex = ViewBag.PageCount }, null)">尾 页</a>}else{<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage + 10 }, null)">...</a></span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.PageCount }, 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):
@using (Html.BeginForm())
{ 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", "PageIndex", new { action = "", controller = "", pageCount = ViewBag.PageCount, currentPage = ViewBag.CurrentPage })
