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 })
