EasyUI——实现展示后台数据代码

下面是View显示代码:

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";    

}

<script type="text/javascript">
    $(function () {
        var editRow = undefined;
        $("#tb1").datagrid({
            fitColumns: true,
            striped: true,
            //这里需要接收【总行数total】和【数据组rows】的【JSON格式】的数据{total:23,rows:[{},{}]}
            url: "/UserExpression/GetAllUserInfos",            
            singleSelect: false,
            pagination: true,
            rownumbers: true,         
            pageSize: 5,
            pageList: [5, 10, 15],
            columns: [
                   [// u.Id,u.UName,u.Pwd,u.Remark,u.SubTime
                     { title: "用户名", field: "UName", allgn: "center", width: 40 },
                     { title: "密码", field: "Pwd", allgn: "center", width: 40 },
                     { title: "备注", field: "Remark", allgn: "center", width: 40 },
                      { title: "保存时间", field: "SubTime", allgn: "center", width: 40 },
                     {
                         title: "编辑", field: "xx", allgn: "center", width: 40, formatter: function (value, row, index) {
                             var btn = '<a class=Update>修改</a>|<a class=delete>删除</a>';
                             return btn;
                         }
                     },
                   ]
            ],
            //在数据加载成功的时候触发。
            onLoadSuccess: function (data) {
                $('.Update').linkbutton({
                    text: '修改',
                    iconCls: 'icon-edit',
                    plain: true,//是否显示边线
                    onClick: function () {
                        var zhi = $("#tb1").datagrid("getSelections");
                        window.location.href = '/HomeText/Edit?id=' + zhi[0].productID;
                    }
                })
                $('.delete').linkbutton({
                    text: '删除',
                    iconCls: 'icon-edit',
                    plain: true,//是否显示边线
                    onClick: function () {
                        var zhi = $("#tb1").datagrid("getSelections");
                        $.ajax({
                            type: 'POST',
                            dataType: 'json',
                            url: '/HomeText/DeleteConfirmed?id=' + zhi[0].productID,
                            success: function (data) {
                                $("#tb1").datagrid("reload");
                            }
                        })
                    }
                })
            },
            toolbar: [
                {
                    text: "添加",
                    iconCls: "icon-add",
                    handler: function () {
                        window.open("/HomeText/Create")
                    }
                },
            {
                text: "删除",
                iconCls: "icon-cancel",
            }
            ],
        })
    })
</script>
<table id="tb1"></table>

 

下面是Controller后台代码:

using IBLL;
using SQLModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MVC展示数据.Controllers
{
    public class UserExpressionController : Controller
    {
        //利用spring.net在Config里面进行配置，这样就不用new对象了
        public IUserInfo UserInfoBLL2 { get; set; }       
        
        #region 加载用户的数据
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult GetAllUserInfos()
        {
            //根据分页显示数据
            int pageSize = Request["rows"] == null ? 5 : int.Parse(Request["rows"]);
            int pageIndex = Request["page"] == null ? 1 : int.Parse(Request["page"]);          
          
            //--------------------------------第几页,每页几条,根据id进行查询
            var data = UserInfoBLL2.LoadByPage(pageIndex, pageSize, n => n.Id)
             //-----避免重复查询   
             .Select(u => new { u.Id, u.UName, u.Pwd, u.Remark, u.SubTime });            
           
            //总的数据条数
            int total = UserInfoBLL2.Load().Count();
            var result = new { total=total,rows=data};
            return Json(result, JsonRequestBehavior.AllowGet);
        } 
        #endregion
    }
}
