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

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

在ArticleController中添加一个返回json类型的JsonList方法

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

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。
