老习惯,先上个效果图:
1、在IBLL
在InterfaceCommonModelService接口中添加获取公共模型列表的方法
首先排序方法
- /// <summary>
- /// 排序
- /// </summary>
- /// <param name="entitys">数据实体集</param>
- /// <param name="roderCode">排序代码[默认:ID降序]</param>
- /// <returns></returns>
- IQueryable<CommonModel> Order(IQueryable<CommonModel> entitys, int roderCode);
- 查询数据方法
- /// <summary>
- /// 查询分页数据列表
- /// </summary>
- /// <param name="totalRecord">总记录数</param>
- /// <param name="model">模型【All全部】</param>
- /// <param name="pageIndex">页码</param>
- /// <param name="pageSize">每页记录数</param>
- /// <param name="title">标题【不使用设置空字符串】</param>
- /// <param name="categoryID">栏目ID【不使用设0】</param>
- /// <param name="inputer">用户名【不使用设置空字符串】</param>
- /// <param name="fromDate">起始日期【可为null】</param>
- /// <param name="toDate">截止日期【可为null】</param>
- /// <param name="orderCode">排序码</param>
- /// <returns>分页数据列表</returns>
- IQueryable<CommonModel> FindPageList(out int totalRecord, int pageIndex, int pageSize, string model, string title, int categoryID, string inputer, Nullable<DateTime> fromDate, Nullable<DateTime> toDate, int orderCode);
2、BLL
- 在CommonModelService写方法实现代码,内容都很简单主要是思路,直接上代码
- public IQueryable<CommonModel> FindPageList(out int totalRecord, int pageIndex, int pageSize, string model, string title, int categoryID, string inputer, Nullable<DateTime> fromDate, Nullable<DateTime> toDate, int orderCode)
- {
- //获取实体列表
- IQueryable<CommonModel> _commonModels = CurrentRepository.Entities;
- if (model == null || model != "All") _commonModels = _commonModels.Where(cm => cm.Model == model);
- if (!string.IsNullOrEmpty(title)) _commonModels = _commonModels.Where(cm => cm.Title.Contains(title));
- if (categoryID > 0) _commonModels = _commonModels.Where(cm => cm.CategoryID == categoryID);
- if (!string.IsNullOrEmpty(inputer)) _commonModels = _commonModels.Where(cm => cm.Inputer == inputer);
- if (fromDate != null) _commonModels = _commonModels.Where(cm => cm.ReleaseDate >= fromDate);
- if (toDate != null) _commonModels = _commonModels.Where(cm => cm.ReleaseDate <= toDate);
- _commonModels = Order(_commonModels, orderCode);
- totalRecord = _commonModels.Count();
- return PageList(_commonModels, pageIndex, pageSize).AsQueryable();
- }
- public IQueryable<CommonModel> Order(IQueryable<CommonModel> entitys, int orderCode)
- {
- switch(orderCode)
- {
- //默认排序
- default:
- entitys = entitys.OrderByDescending(cm => cm.ReleaseDate);
- break;
- }
- return entitys;
- }
3、web
由于CommonModel跟我们前台显示的数据并不一致,为了照顾datagrid中的数据显示再在Ninesky.Web.Models中再构造一个视图模型CommonModelViewModel
- using System;
- namespace Ninesky.Web.Models
- {
- /// <summary>
- /// CommonModel视图模型
- /// <remarks>
- /// 创建:2014.03.10
- /// </remarks>
- /// </summary>
- public class CommonModelViewModel
- {
- public int ModelID { get; set; }
- /// <summary>
- /// 栏目ID
- /// </summary>
- public int CategoryID { get; set; }
- /// <summary>
- /// 栏目名称
- /// </summary>
- public string CategoryName { get; set; }
- /// <summary>
- /// 模型名称
- /// </summary>
- public string Model { get; set; }
- /// <summary>
- /// 标题
- /// </summary>
- public string Title { get; set; }
- /// <summary>
- /// 录入者
- /// </summary>
- public string Inputer { get; set; }
- /// <summary>
- /// 点击
- /// </summary>
- public int Hits { get; set; }
- /// <summary>
- /// 发布日期
- /// </summary>
- public DateTime ReleaseDate { get; set; }
- /// <summary>
- /// 状态
- /// </summary>
- public int Status { get; set; }
- /// <summary>
- /// 状态文字
- /// </summary>
- public string StatusString { get { return Ninesky.Models.CommonModel.StatusList[Status]; } }
- /// <summary>
- /// 首页图片
- /// </summary>
- public string DefaultPicUrl { get; set; }
- }
- }
在ArticleController中添加一个返回json类型的JsonList方法
- /// <summary>
- /// 文章列表Json【注意权限问题,普通人员是否可以访问?】
- /// </summary>
- /// <param name="title">标题</param>
- /// <param name="input">录入</param>
- /// <param name="category">栏目</param>
- /// <param name="fromDate">日期起</param>
- /// <param name="toDate">日期止</param>
- /// <param name="pageIndex">页码</param>
- /// <param name="pageSize">每页记录</param>
- /// <returns></returns>
- public ActionResult JsonList(string title, string input, Nullable<int> category, Nullable<DateTime> fromDate, Nullable<DateTime> toDate, int pageIndex = 1, int pageSize = 20)
- {
- if (category == null) category = 0;
- int _total;
- var _rows = commonModelService.FindPageList(out _total, pageIndex, pageSize, "Article", title, (int)category, input, fromDate, toDate, 0).Select(
- cm => new Ninesky.Web.Models.CommonModelViewModel()
- {
- CategoryID = cm.CategoryID,
- CategoryName = cm.Category.Name,
- DefaultPicUrl = cm.DefaultPicUrl,
- Hits = cm.Hits,
- Inputer = cm.Inputer,
- Model = cm.Model,
- ModelID = cm.ModelID,
- ReleaseDate = cm.ReleaseDate,
- Status = cm.Status,
- Title = cm.Title
- });
- return Json(new { total = _total, rows = _rows.ToList() });
- }
下面是做界面了,在添加 List方法,这里不提供任何数据,数据在JsonList 中获得
- /// <summary>
- /// 全部文章
- /// </summary>
- /// <returns></returns>
- public ActionResult List()
- {
- return View();
- }
右键添加视图
- <div id="toolbar">
- <div>
- <a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-edit',plain:true" >修改</a>
- <a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-remove',plain:true" ">删除</a>
- <a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-reload',plain:true" onclick="$('#article_list').datagrid('reload');">刷新</a>
- </div>
- <div class="form-inline">
- <label>栏目</label><input id="combo_category" data-options="url:'@Url.Action("JsonTree", "Category", new { model="Article" })'" class="easyui-combotree" />
- <label>标题</label> <input id="textbox_title" class="input-easyui" style="width:280px" />
- <label>录入人</label><input id="textbox_inputer" class="input-easyui" />
- <label>添加日期</label>
- <input id="datebox_fromdate" type="datetime" class="easyui-datebox" style="width:120px" /> -
- <input id="datebox_todate" type="datetime" class="easyui-datebox" style="width:120px; " />
- <a href="#" id="btn_search" data-options="iconCls:'icon-search'" class="easyui-linkbutton">查询</a>
- </div>
- </div>
- <table id="article_list"></table>
- <script src="~/Scripts/Common.js"></script>
- <script type="text/javascript">
- $("#article_list").datagrid({
- loadMsg: '加载中……',
- pagination:true,
- url: '@Url.Action("JsonList","Article")',
- columns: [[
- { field: 'ModelID', title: 'ID', checkbox: true },
- { field: 'CategoryName', title: '栏目'},
- { field: 'Title', title: '标题'},
- { field: 'Inputer', title: '录入', align: 'right' },
- { field: 'Hits', title: '点击', align: 'right' },
- { field: 'ReleaseDate', title: '发布日期', align: 'right', formatter: function (value, row, index) { return jsonDateFormat(value); } },
- { field: 'StatusString', title: '状态', width: 100, align: 'right' }
- ]],
- toolbar: '#toolbar',
- idField: 'ModelID',
- });
- //查找
- $("#btn_search").click(function () {
- $("#article_list").datagrid('load', {
- title: $("#textbox_title").val(),
- input: $("#textbox_inputer").val(),
- category: $("#combo_category").combotree('getValue'),
- fromDate: $("#datebox_fromdate").datebox('getValue'),
- toDate: $("#datebox_todate").datebox('getValue')
- });
- });
- }
- </script>
上面都是easyui-datagrid的内容。
总体思路是BLL中实现查询公共模型列表,web中添加一个JsonList方法调用BLL中的方法并返回列表的Json类型。然后再添加一个List调用JsonList用来显示。下篇文章做删除和修改操作,希望大家会持续关注。
