這篇文章給大家分享的是有關ASP.NET MVC4 Razor模板如何實現分頁效果的內容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
一、無數據提交
第一步,建立一個 Controller命名為PageIndex的空控制器,自定義一個方法如下:
public ActionResult PageIndex(string action, string controller, int currentPage, int pageCount)
{
//int count = db.Product.Count();
ViewBag.PageCount = pageCount;//從操作中獲取總數據頁數將傳入分頁視圖頁面
ViewBag.CurrentPage = currentPage;//從操作中獲取當前頁數將傳入分頁視圖頁面
ViewBag.action = action;
ViewBag.controller = controller;
return PartialView();
}傳入四個參數:
action:操作(要分頁的視圖的操作,默認為Index);
controller:控制器;
currentPage:當前頁數;
pageCount:數據總頁數
第二步:添加視圖(PageIndex)
@if (ViewBag.PageCount == null || ViewBag.PageCount == 0)
{
<span>您好,當前沒有數據顯示!</span>
}
else
{
if (ViewBag.CurrentPage <= 10)
{
<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = 1 }, null)">
首頁</a>|</span>
}
else
{
<a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = 1 }, null)">
首頁</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 頁</a>|</span>
}
if (ViewBag.CurrentPage > 1)
{
<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage - 1 }, null)">
上一頁</a>|</span>
}
if (ViewBag.PageCount > ViewBag.CurrentPage)
{
<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage + 1 }, null)">
下一頁</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 頁</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 頁</a>
}
<span >當前頁數: @ViewBag.CurrentPage | 共 @ViewBag.PageCount 頁
</span>
}第三步:操作的視圖的控制器修改
public ViewResult Index(int? pageIndex)
{
int pageInd = pageIndex.HasValue ? pageIndex.Value : 1;
ViewBag.PageCount = (int)Math.Ceiling(result.Count() / 20.0);
//這里的是take,按照每頁20個顯示
return View(result.OrderBy(t => t.PID).Skip((pageInd - 1) * 20).Take(20));
}第四步:頁面調用(即最后一步)
復制代碼 代碼如下:
@Html.Action("PageIndex", "Product", new { action = "Index", controller = "Log", pageCount = ViewBag.PageCount, currentPage = ViewBag.CurrentPage })
一般來說,數據都是變動的。
二、有數據提交
第一步:建立一個 Controller命名為PageIndex的空控制器,自定義一個方法如下:
public ActionResult PageIndexKey(int currentPage, int pageCount)
{
ViewBag.PageCount = pageCount;//從操作中獲取總數據頁數將傳入分頁視圖頁面
ViewBag.CurrentPage = currentPage;//從操作中獲取當前頁數將傳入分頁視圖頁面
return PartialView();
}第二步:建立分布視圖
<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>當前沒有數據</span>
}
else
{
if (ViewBag.CurrentPage <= 10)
{
<span><a pageindex="1" href="#">首頁</a>|</span>
}
else
{
<span><a pageindex="1" href="#">首頁</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 頁</a>|</span>
}
if (ViewBag.CurrentPage >1)
{
<span><a pageIndex="@(ViewBag.CurrentPage - 1)" href="#">上一頁</a>|</span>
}
if (ViewBag.PageCount > ViewBag.CurrentPage)
{
<span><a pageIndex="@(ViewBag.CurrentPage + 1)" href="#">下一頁</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 頁</a></span>
}
<span >當前頁數: @ViewBag.CurrentPage | 共 @ViewBag.PageCount 頁
</span>
}
</div>第三步:修改操作視圖和控制器
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));
}視圖(頁面調用):
@using (Html.BeginForm())
{
根據性別得到查詢結果
性別: @Html.TextBox("sex")
<input type="submit" value="查詢" />
@Html.Action("PageIndexKey", "PageIndex", new { pageCount = ViewBag.PageCount, currentPage = ViewBag.CurrentPage })
}
Example:
//數據,一個list的集合
List<string> s = new List<string>();
s.Add("張軍");
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 })感謝各位的閱讀!關于“ASP.NET MVC4 Razor模板如何實現分頁效果”這篇文章就分享到這里了,希望以上內容可以對大家有一定的幫助,讓大家可以學到更多知識,如果覺得文章不錯,可以把它分享出去讓更多的人看到吧!
