jquery的前端框架挺多的,有easyUI ,bootstrap...,对于做系统软件或许easyUI比较好,因为里面控件很丰富,而bootstrap非常简洁大方,但是控件相
对比较少,特别是复杂的网格控件,几乎要自己来写!
介绍一下的easyUI 的datagrid,感觉写法还是比较简单易懂,重用性比较强!
主要实现了显示数据,查询数据(序列化传参),datagrid分页样式选用。
页面如下:
例子依赖:
1、asp.net mvc
2、easyui文件依赖包
下载地址:http://www.jeasyui.com/download/index.php
3、jquery.serialize-object.js
下载地址:https://github.com/macek/jquery-serialize-object
后端代码:
1、依赖的类:
1)Pager 兼容EasyUi 分页(用于查询条件实体继承)
1 /// <summary> 2 /// 兼容EasyUi 分页(用于查询条件实体继承) 3 /// </summary> 4 public class Pager 5 { 6 /// <summary> 7 /// 兼容EasyUi 分页参数,当前页 8 /// </summary> 9 public Int32 Page { get; set; } 10 11 /// <summary> 12 /// 兼容EasyUi 分页参数,每页记录数 13 /// </summary> 14 public Int32 Rows { get; set; } 15 }View Code
2)PersonConditions 查询条件实体类,继承Pager
1 /// <summary> 2 /// 查询条件实体类 3 /// </summary> 4 public class PersonConditions:Pager 5 { 6 public String Code { get; set; } 7 public String Name { get; set; } 8 public String Sex { get; set; } 9 public String Addr { get; set; } 10 public String Phone { get; set; } 11 public Double? Price { get; set; } 12 }View Code
3)Person Person实体
1 /// <summary> 2 /// Person实体 3 /// </summary> 4 public class Person 5 { 6 public String Code { get; set; } 7 public String Name { get; set; } 8 public String Sex { get; set; } 9 public String Addr { get; set; } 10 public String Phone { get; set; } 11 public Double? Price { get; set; } 12 }View Code
4)DataGridObj 兼容EasyUi DataGrid分页数据结构
1 /// <summary> 2 /// 兼容EasyUi DataGrid分页数据结构 3 /// </summary> 4 public class DataGridObj 5 { 6 /// <summary> 7 /// 总数量 8 /// </summary> 9 public Int32 total { get; set; } 10 11 /// <summary> 12 /// 数据 13 /// </summary> 14 public Object rows { get; set; } 15 }View Code
2、Home控制器
1)Index() 加载页面的方法
2)GetJson() DataGrid 获取数据的方法
1 public class HomeController : Controller 2 { 3 public ActionResult Index() 4 { 5 return View(); 6 } 7 8 9 [HttpPost] 10 public JsonResult GetJson(PersonConditions personWhere) 11 { 12 DataGridObj dgObj = new DataGridObj(); 13 14 #region 产生List<Person>数据 15 List<Person> list = new List<Person>(); 16 for (int i = 0; i < 15; i++) 17 { 18 Person person = new Person() 19 { 20 Code = "code" + i.ToString(), 21 Name = "name" + i.ToString(), 22 Sex=i%2==0?"男":"女", 23 Addr="Addr"+i.ToString(), 24 Phone="123456"+i.ToString(), 25 Price = i 26 }; 27 28 list.Add(person); 29 } 30 #endregion 31 32 IQueryable<Person> iqPerson = list.AsQueryable(); 33 #region 查询条件 34 if (String.IsNullOrEmpty(personWhere.Code) == false) 35 iqPerson = iqPerson.Where(a => a.Code == personWhere.Code); 36 if (String.IsNullOrEmpty(personWhere.Name) == false) 37 iqPerson = iqPerson.Where(a => a.Name == personWhere.Name); 38 if (personWhere.Price != null) 39 iqPerson = iqPerson.Where(a => a.Price == personWhere.Price); 40 #endregion 41 42 list = iqPerson.ToList(); 43 dgObj.rows = list.Skip((personWhere.Page - 1) * personWhere.Rows).Take(personWhere.Rows); 44 dgObj.total = list.Count(); 45 return Json(dgObj, JsonRequestBehavior.AllowGet); 46 } 47 }View Code
前端代码:
1、脚本
1)Common:通用类
SerializeObject:序列化form为对象
2)EasyUIHelper: EasyUI的帮助类
InitTextBox:设置textbox共同的初始属性,统一风格
InitDgPagination:设置datagrid的分页样式(放在datagrid初始化后),dgId为datagrid的id
3)myDgObj:进行对本页面datagrid的初始化,各种方法定义、调用
4)$(function () { });别忘了在里面调用初始化控件方法
2、HTML
1)form 查询条件
2)id为dg的div为用于绑定datagrid
3、页面代码

注意:
$("#dg").datagrid("load", Common.SerializeObject());
查询时,通过序列化form为对象post到GetJson()作为入参
