本文将使用jqgrid在Razor Page中实现分页功能。
List.cshtml代码如下:
1 @page 2 @model ListModel 3 @{ 4 Layout = "~/Pages/Shared/_Index.cshtml"; 5 } 6 7 <script> 8 $(function () { 9 gridList(); 10 }); 11 12 function gridList() { 13 var $gridList = $("#gridList"); 14 $gridList.dataGrid({ 15 url: "/Admin/User/List?handler=GridJson", 16 height: $(window).height() - 128, 17 colModel: [ 18 { label: ‘主键‘, name: ‘F_Id‘, hidden: true }, 19 { label: ‘账户‘, name: ‘F_Account‘, width: 80, align: ‘left‘ }, 20 { label: ‘姓名‘, name: ‘F_RealName‘, width: 80, align: ‘left‘ }, 21 { 22 label: ‘性别‘, name: ‘F_Gender‘, width: 60, align: ‘center‘, 23 formatter: function (cellvalue) { 24 if (cellvalue === true) { 25 return ‘男‘; 26 } else { 27 return ‘女‘; 28 } 29 } 30 }, 31 { label: ‘手机‘, name: ‘F_MobilePhone‘, width: 80, align: ‘left‘ }, 32 { 33 label: ‘公司‘, name: ‘F_OrganizeId‘, width: 150, align: ‘left‘, 34 formatter: function (cellvalue) { 35 return top.clients.organize[cellvalue] == null ? "" : top.clients.organize[cellvalue].fullname; 36 } 37 }, 38 { 39 label: ‘部门‘, name: ‘F_DepartmentId‘, width: 80, align: ‘left‘, 40 formatter: function (cellvalue) { 41 return top.clients.organize[cellvalue] == null ? "" : top.clients.organize[cellvalue].fullname; 42 } 43 }, 44 { 45 label: ‘岗位‘, name: ‘F_DutyId‘, width: 80, align: ‘left‘, 46 formatter: function (cellvalue) { 47 return top.clients.duty[cellvalue] == null ? "" : top.clients.duty[cellvalue].fullname; 48 } 49 }, 50 { 51 label: ‘创建时间‘, name: ‘F_CreatorTime‘, width: 80, align: ‘left‘, 52 formatter: "date", formatoptions: { srcformat: ‘Y-m-d‘, newformat: ‘Y-m-d‘ } 53 }, 54 { 55 label: "允许登录", name: "F_EnabledMark", width: 60, align: "center", 56 formatter: function (cellvalue) { 57 if (cellvalue) { 58 return ‘<span class=\"label label-success\">正常</span>‘; 59 } else if (cellvalue === 0) { 60 return ‘<span class=\"label label-default\">禁用</span>‘; 61 } 62 } 63 }, 64 { label: ‘备注‘, name: ‘F_Description‘, width: 200, align: ‘left‘ } 65 ], 66 pager: "#gridPager", 67 sortname: ‘F_DepartmentId asc, F_CreatorTime desc‘, 68 viewrecords: true 69 }); 70 71 $("#btn_search").click(function () { 72 $gridList.jqGrid(‘setGridParam‘, { 73 postData: { keyword: $("#txt_keyword").val() } 74 }).trigger(‘reloadGrid‘); 75 }); 76 } 77 78 function btn_add() { 79 $.modalOpen({ 80 id: "Form", 81 title: "新增用户", 82 url: "/Admin/User/Form", 83 width: "700px", 84 height: "510px", 85 callBack: function (iframeId) { 86 top.frames[iframeId].submitForm(); 87 } 88 }); 89 } 90 91 function btn_edit() { 92 var keyValue = $("#gridList").jqGridRowValue().F_Id; 93 $.modalOpen({ 94 id: "Form", 95 title: "修改用户", 96 url: "/Admin/User/Form?keyValue=" + keyValue, 97 width: "700px", 98 height: "510px", 99 callBack: function (iframeId) { 100 top.frames[iframeId].submitForm();

111 } 112 }) 113 } 114 115 function btn_details() { 116 var keyValue = $("#gridList").jqGridRowValue().F_Id; 117 $.modalOpen({ 118 id: "Details", 119 title: "查看用户", 120 url: "/Admin/User/Details?keyValue=" + keyValue, 121 width: "700px", 122 height: "550px", 123 btn: null, 124 }); 125 } 126 127 function btn_revisepassword() { 128 var keyValue = $("#gridList").jqGridRowValue().F_Id; 129 var account = $("#gridList").jqGridRowValue().F_Account; 130 var realName = $("#gridList").jqGridRowValue().F_RealName; 131 $.modalOpen({ 132 id: "RevisePassword", 133 title: ‘重置密码‘, 134 url: ‘/Admin/User/RevisePassword?keyValue=‘ + keyValue + "&account=" + escape(account) + ‘&realName=‘ + escape(realName), 135 width: "450px", 136 height: "260px", 137 callBack: function (iframeId) { 138 top.frames[iframeId].submitForm(); 139 } 140 }); 141 } 142 143 function btn_disabled() { 144 var keyValue = $("#gridList").jqGridRowValue().F_Id; 145 $.modalConfirm("注:您确定要【禁用】该项账户吗?", function (r) { 146 if (r) { 147 $.submitForm({ 148 url: "/Admin/User/List?handler=DisabledAccount", 149 param: { keyValue: keyValue }, 150 success: function () { 151 $.currentWindow().$("#gridList").trigger("reloadGrid"); 152 } 153 }) 154 } 155 }); 156 } 157 158 function btn_enabled() { 159 var keyValue = $("#gridList").jqGridRowValue().F_Id; 160 $.modalConfirm("注:您确定要【启用】该项账户吗?", function (r) { 161 if (r) { 162 $.submitForm({ 163 url: "/Admin/User/List?handler=EnabledAccount", 164 param: { keyValue: keyValue }, 165 success: function () { 166 $.currentWindow().$("#gridList").trigger("reloadGrid"); 167 } 168 }) 169 } 170 }); 171 } 172 </script> 173 174 <div class="topPanel"> 175 <div class="toolbar"> 176 <div class="btn-group"> 177 <a class="btn btn-primary" onclick="$.reload()"><span class="glyphicon glyphicon-refresh"></span></a> 178 </div> 179 <div class="btn-group"> 180 <a id="NF-add" authorize="yes" class="btn btn-primary dropdown-text" onclick="btn_add()"><i class="fa fa-plus"></i>新建用户</a> 181 </div> 182 <div class="operate"> 183 <ul class="nav nav-pills"> 184 <li class="first">已选中<span>1</span>项</li> 185 <li><a id="NF-edit" authorize="yes" onclick="btn_edit()"><i class="fa fa-pencil-square-o"></i>修改用户</a></li> 186 <li><a id="NF-delete" authorize="yes" onclick="btn_delete()"><i class="fa fa-trash-o"></i>删除用户</a></li> 187 <li><a id="NF-Details" authorize="yes" onclick="btn_details()"><i class="fa fa-search-plus"></i>查看用户</a></li> 188 <li class="split"></li> 189 <li><a id="NF-revisepassword" authorize="yes" onclick="btn_revisepassword()"><i class="fa fa-key"></i>密码重置</a></li> 190 <li class="split"></li> 191 <li><a id="NF-disabled" authorize="yes" onclick="btn_disabled()"><i class="fa fa-stop-circle"></i>禁用</a></li> 192 <li><a id="NF-enabled" authorize="yes" onclick="btn_enabled()"><i class="fa fa-play-circle"></i>启用</a></li> 193 </ul> 194 <a href="javascript:;" class="close"></a> 195 </div> 196 <script>$(‘.toolbar‘).authorizeButton()</script> 197 </div> 198 <div class="search"> 199 <table> 200 <tr> 201 <td> 202 <div class="input-group"> 203 <input id="txt_keyword" type="text" class="form-control" placeholder="账户/姓名/手机" style="width: 200px;"> 204 <span class="input-group-btn"> 205 <button id="btn_search" type="button" class="btn btn-primary"><i class="fa fa-search"></i></button> 206 </span> 207 </div> 208 </td> 209 </tr> 210 </table> 211 </div> 212 </div> 213 <div class="gridPanel"> 214 <table id="gridList"></table> 215 <div id="gridPager"></div> 216 </div>
$gridList.dataGrid的定义见下一节。
jqGrid异步请求的默认请求参数属性包含:
{ page:"page", //当前页码 rows:"rows", //每页数量 sort:"sidx", //排序字段 order:"sord", //排序类型 search:"_search", nd:"nd", id:"id", oper:"oper", editoper:"edit", addoper:"add", deloper:"del", subgridid:"id", npage:null, totalrows:"totalrows" }
可以看到参数中包含名为page的参数,但是在Razor Page中名为page的参数已经被占用了,如图所示:
可以看到page参数是一个字符串类型,代表的是当前Page的地址。因此,不能使用再使用page作为当前页的名称,否则将会导致无法正常翻页。所以我们需要重新定义jqgrid的请求参数名称。可喜的是jqGrid提供了prmNames这个属性用来修改请求参数属性,因此我们对jqgrid做二级封装,代码如下:
$.fn.dataGrid = function (options) { var defaults = { datatype: "json", autowidth: true, rownumbers: true, shrinkToFit: false, gridview: true, rowNum: 15, rowList: [10, 15, 30, 50, 100], prmNames: { ‘page‘: ‘PageIndex‘, ‘rows‘: ‘PageSize‘, ‘order‘: ‘SortType‘, ‘sort‘: ‘SortColumn‘ } }; var options = $.extend(defaults, options); var $element = $(this); options["onSelectRow"] = function (rowid) {//选中某一行之后 var length = $(this).jqGrid("getGridParam", "selrow").length; var $operate = $(".operate"); if (length > 0) { $operate.animate({ "left": 0 }, 200); } else { $operate.animate({ "left": ‘-100.1%‘ }, 200); } $operate.find(‘.close‘).click(function () { $operate.animate({ "left": ‘-100.1%‘ }, 200); }); }; $element.jqGrid(options); };
为了符合C#的属性命名规范,我们将几个需要接受的参数都使用匈牙利命名法。
为了接收前台jqgird传递的参数,我们定义一个Class,内容如下:
/// <summary> /// 分页信息 /// </summary> public class PagerInfo { /// <summary> /// 表名称 /// </summary> public string TableName { get; set; } /// <summary> /// 主键名称 /// </summary> public string PKField { get; set; } = "id"; /// <summary> /// 返回列 逗号分隔 /// </summary> public string ReturnField { get; set; } = "*"; /// <summary> /// 查询条件 /// </summary> public string QueryString { get; set; } /// <summary> /// 排序列 /// </summary> public string SortColumn { get; set; } /// <summary> /// 排序类型 /// </summary> public string SortType { get; set; } /// <summary> /// 当前页 /// </summary> public int PageIndex { get; set; } /// <summary> /// 每页条数 /// </summary> public int PageSize { get; set; } /// <summary> /// 总记录数 /// </summary> public int TotalCount { get; set; } /// <summary> /// 总页数 /// </summary> public int PageCount { get { if (this.TotalCount <= 0) { return 0; } return TotalCount % this.PageSize == 0 ? TotalCount / this.PageSize : TotalCount / this.PageSize + 1; } } }
代码中的红色部分就是与我们自定义的jqgrid请求参数对应。分页获取数据的方法:
/// <summary> /// 分页获取对象 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="pagerInfo"></param> /// <returns></returns> public static List<T> GetPageList<T>(PagerInfo pagerInfo) { using (var conn = ConnectionFactory.GetInstance()) { var param = new DynamicParameters(); param.Add("@tbName", pagerInfo.TableName); param.Add("@pkField", pagerInfo.PKField); param.Add("@pageIndex", pagerInfo.PageIndex); param.Add("@pageSize", pagerInfo.PageSize); param.Add("@returnField", pagerInfo.ReturnField); param.Add("@orderField", pagerInfo.SortColumn); param.Add("@queryStr", pagerInfo.QueryString); param.Add("@itemCount", 0, DbType.Int32, ParameterDirection.Output); param.Add("@pageCount", 0, DbType.Int32, ParameterDirection.Output); var list = conn.Query<T>("SP_Pagination", param, commandType: CommandType.StoredProcedure).ToList(); pagerInfo.TotalCount = param.Get<int>("@itemCount"); return list; } }
可以看到代码中调用了Mysql数据库中名为:SP_Pagination 的存储过程,该存储过程定义见下一节。
SP_Pagination定义如下:
CREATE DEFINER=`root`@`%` PROCEDURE `SP_Pagination`(in tbName varchar(20),#表名 in returnField varchar(100),#要显示的列名 in queryStr varchar(500),#where条件(只需要写where后面的语句) in orderField varchar(500),#排序条件(只需要写order by后面的语句) in pageSize int,#每一页显示的记录数 in pageIndex int,#当前页 out itemCount int, out pageCount int) BEGIN if (pageSize < 1)then set pageSize = 20; end if; if (pageIndex < 1)then set pageIndex = 1; end if; if(LENGTH(queryStr)>0)then set queryStr=CONCAT(‘ where ‘,queryStr); end if; if(orderField is not null and LENGTH(orderField)>0)then set orderField = CONCAT(‘ order by ‘,orderField); end if; set @strsql = CONCAT(‘select ‘, returnField, ‘ from ‘, tbName, ‘ ‘, queryStr, ‘ ‘, orderField, ‘ limit ‘, pageIndex * pageSize - pageSize, ‘,‘, pageSize); prepare stmtsql from @strsql; execute stmtsql; deallocate prepare stmtsql; set @strsqlcount=concat(‘select count(1) as count into @itemCount from ‘,tbName,‘‘,queryStr); prepare stmtsqlcount from @strsqlcount; execute stmtsqlcount; deallocate prepare stmtsqlcount; set itemCount=@itemCount; set pageCount = (itemCount + pageIndex - 1) / pageSize; END
至此,Razor Page分页功能实现完毕。需要特别注意的是jqgrid的page参数与Razor Page的page参数冲突的问题。
