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 })
