一、页面代码,分为三部分,一是查询条件部分,二是数据部分,二是页码条
<div id="ticketoutquery"><td style="width: 70px; text-align: right"> 订票单号: <td style="text-align: left"> @Html.TextBoxFor(s => s.TicketNo) <td style="width: 70px; text-align: right"> 出票时间: @Html.TextBoxFor(s => s.CreateDateStart, new { @class = "datepicker" }) @Html.TextBoxFor(s => s.CreateDateEnd, new { @class = "datepicker" }) <td style="width: 70px; text-align: right"><input type="button" id="tbQueryticketout" onclick="doQueryticketoutProcessing(1)" class="btn btn-primary" value="查询" />
<div id="TaskList"> @Html.Raw(@ViewData["TaskLists"])
<div class="page_nav" id="pageBar" style="margin:0,auto"> @Html.Raw(OilDigital.TicketSys2.Web.PageBarHelper.GetPagaBar((int)ViewData["PageIndex"], (int)ViewData["PageCount"], (int)ViewData["recoredCount"]))
二、页面条码类封装如下:
public class PageBarHelper { public static string GetPagaBar(int pageIndex, int pageCount, int recoredCount) { if (pageCount == 1) { return string.Empty; } int start = pageIndex - 5;//计算起始位置.要求页面上显示10个数字页码. if (start < 1) { start = 1; } int end = start + 9;//计算终止位置. if (end > pageCount) { end = pageCount; //重新计算一下Start值. start = end - 9 < 1 ? 1 : end - 9; } StringBuilder sb = new StringBuilder(); if (pageIndex > 1) { //sb.AppendFormat("上一页", pageIndex - 1);、 sb.AppendFormat("上一页", pageIndex - 1); } for (int i = start; i <= end; i++) { if (i == pageIndex) { sb.Append(i); } else { sb.AppendFormat("{0}", i); } } if (pageIndex < pageCount) { sb.AppendFormat("下一页", pageIndex + 1); } if (recoredCount >0) { sb.AppendFormat(" 每页10条,共{0}条", recoredCount); } return sb.ToString(); } }
三、点击查询后会触发doQueryticketoutProcessing方法
function doQueryticketoutProcessing(pageIndex) { var ticketNoval = $('#TicketNo').val(); //订票单号 var CreateDateStart = $('#CreateDateStart').val(); //出票时间 var CreateDateEnd = $('#CreateDateEnd').val(); //出票时间 if (pageIndex == null || pageIndex == undefined || pageIndex <1) { pageIndex = 1; } var type = $("#type").val(); showMsg(); $.ajax({ type: "post", url: approvalUrl + "/GetProcessingTicketoutTaskListByQuery", data: { ReceiveNumber: ticketNoval, createDateStart: CreateDateStart, createDateEnd: CreateDateEnd, type: type, pageIndex: pageIndex }, datatype: "html", success: function (data) { hideMsg(); if (data.ticketList == "") { $("#taskList").html("暂时无任务列表!"); } else { $("#TaskList").empty(); $("#TaskList").html(data.ticketList); } $("#pageBar").html(data.pageBar); }, error: function (req, status, error) { hideMsg(); console.log("获取订票单失败,原因如下:\r\n" + error); } }); }
三、后台除了查询的条件外,分页的参数主要是pageIndex 和 pageSize. 传入后台后返回总记录数 recoredCount 和 总页数pageCount 下面给出分页的核心代码
public static IQueryableGetByStateAndDateTime(string ReceiveNumber, string ticketState, DateTime startDate, DateTime endDate,int pageIndex,int pageSize) { IQueryabletickets = dao.GetQueryable().Where(s => s.StateCode == "已出票" && s.CreatedTime > startDate && s.CreatedTime < endDate); if (!string.IsNullOrEmpty(ReceiveNumber)) { tickets = tickets.Where(s => s.ReceiveNumber == ReceiveNumber.Trim()); } if(pageIndex!=0) { tickets = tickets.OrderBy(s=>s.CreatedTime).Skip((pageIndex - 1) * pageSize).Take(pageSize); } return tickets; }
pageCount计算方法
pageCount = Convert.ToInt32(Math.Ceiling((double)recoredCount / pageSize));
四、分页控件的css样式如下:
page_nav{clear:both; padding:15px 0; color:#666; font:normal 12px/24px Arial; text-align:center;} .page_nav a{display:inline-block; height:22px; margin:0 2px; padding:0 8px; text-decoration:none; border:solid 1px #dbe5ee; -moz-border-radius:2px; -webkit-border-radius:2px; -khtml-border-radius:2px; border-radius:2px; background:#fff; color:#333; font:normal 12px/22px Arial, Helvetica, sans-serif; cursor:pointer;} .page_nav strong{display:inline-block; height:24px; margin:0 3px; padding:0 8px; border:none; -moz-border-radius:2px; -webkit-border-radius:2px; -khtml-border-radius:2px; border-radius:2px; background:#C00; color:#fff; font-weight:normal; line-height:24px; text-decoration:none;} .page_nav a:hover, .page_nav a.on{height:24px; margin:0 3px; border:none; background:#C00; color:#fff; line-height:24px; text-decoration:none;} .page_nav a.select{cursor:default;} .page_nav .view_all{display:block; text-align:center;} .page_nav .view_all a{height:auto; margin:0; padding:0; border:none; color:#06c; line-height:24px;} .page_nav .view_all a:hover{height:auto; margin:0; padding:0; background:none;}
注意事项:
必须配置nhibernate如下:有些是.MsSql2000Dialect 在使用分页的方法时是会报错的。
