页面的HTML部分如下：

< div class ="tableContainer">
< input id ="currentPage" type ="hidden" value =" @ViewData[ "currentPage"] "/>
< input id ="totalPages" type ="hidden" value =" @ViewData["totalPages" ] " />
< table class ="table table-hover table-striped">
< thead>
< tr>
< th class ="col-md-4 text-center"> 乘车码 </th >
< th class ="col-md-4 text-center"> 订单号 </th >
< th class ="col-md-4 text-center"> 订单日期 </th >
</ tr>
</ thead>
< tbody>
@foreach ( var item in Model)
{
< tr>
< td> @item.BusNo </ td>
< td> @item.OrderId </ td>
< td> @item.OrderDate </ td>
</ tr>
}
</ tbody>
</ table>
< ul id ="example"></ ul>
</ div >

 

页面的javascript部分如下：（此处需要引用插件bootstrap-paginator，具体的使用方法也在官网能看到，这里就不再详述）

@ Scripts.Render( "~/bundles/bootstrap-paginator" )
< script type ="text/javascript">
$( \'#example\' ).bootstrapPaginator({
currentPage: $( \'#currentPage\' ).val(), //当前页
totalPages: $( \'#totalPages\' ).val(), //总页数
bootstrapMajorVersion: 3, //兼容Bootstrap3.x版本
tooltipTitles: function (type, page) {
switch (type) {
case "first" :
return "第一页" ;
case "prev" :
return "上一页" ;
case "next" :
return "下一页" ;
case "last" :
return "最后一页" ;
case "page" :
return page;
}
return "" ;
},
onPageClicked: function (event, originalEvent, type, page) {
$.get( \'/Home/GetPaginationData\' , { currentPage: page, pageSize:10 }, function (view) {
$( \'#tableTest\' ).html(view);
});
}
});
</ script >

 

上面的“#tableTest”是一个div，是< div class ="tableContainer">的父节点，在父页面中占位，就是说当页面数据返回将刷新整个PartialView，后台是一个GET，如下：

 

public ActionResult GetPaginationData( int currentPage = 1, int pageSize = 10)
{
using (var context = new TestEntities ())
{
int count;
var q = (from a in context.Tickets
join b in context.Order on a.OrderId equals b.Id
select new TableItem
{
BusNo = a.BusNumber,
OrderId = b.Id,
OrderDate = b.OrderDateTime,
}).Pagination(currentPage, pageSize, out count);
var data = q.ToList();
ViewData[ "totalPages" ] = count / pageSize + 1; //计算分页后总的页面数
ViewData[ "currentPage" ] = currentPage; //当前页码
return PartialView("~/Views/Home/OrderList.cshtml" ,data);
}
}

 

 其中的Pagination扩展函数用于数据库分页，请参考我的另外一篇博文 “Entity Framework 分页处理”
