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。
