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。
