EasyUI实现分页、搜索、行按钮功能

1、html+js代码:

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
     <link rel="stylesheet" type="text/css" href="~/jquery-easyui-1.5.3/themes/default/easyui.css">
    <link rel="stylesheet" type="text/css" href="~/jquery-easyui-1.5.3/themes/icon.css">
    <script src="~/jquery-easyui-1.5.3/jquery.min.js"></script>
    <script src="~/jquery-easyui-1.5.3/jquery.easyui.min.js"></script>
</head>
<body>    
    <div style="margin-bottom:20px">
        姓名:<input class="easyui-textbox" id="btnSearchName" style="width:150px;height:32px;">
        <input type="button" value="搜索" onclick="search()" />
    </div>
    
    <table id="dg" title="列表" class="easyui-datagrid" style="width:100%;">  
    </table>  

   <script>
       var params = {};
       $(function () {
           loadData(params);
       });

       function loadData(params) {
           $('#dg').datagrid({
               url: '/Page/GetPageData',//数据请求地址  
               method: 'post', 
               pagination: true,//分页显示  
               fitColumns: true,//自动适应宽度  
               autoRowHeight: true,//自动行高度  
               loadMsg: '正在加载...',
               nowrap: true,//设置为true 有利于提高性能  
               idField: 'Number',//字段标识  
               rownumbers: true,//显示行号  
               singleSelect: true,//只允许选择一行  
               pageNumber: 1,//初始化页面数量  
               pageSize: 10,//初始化显示条数  
               pageList: [10, 20, 30, 40, 60],//分页列表  
               columns: [[
                   { field: 'Name', title: '姓名', width: 50 },
                   { field: 'Number', title: '工号', width: 50 },
                   {
                       field: 'action', title: '操作', width: 10, align: 'center',
                       formatter: function (value, row, index) {
                           //row.ID,数据id(主键)
                           var a = '<a href="#" onclick="edit(' + row.ID + ')">Edit</a> ';
                           var b = ' <a href="#" onclick="del(' + row.ID + ')">Delete</a>';
                           return a + b;
                       }
                   }
               ]],
               queryParams: params  //参数
           });
       }

       function search() {
           var name = $("#btnSearchName").val();
           params.name = name;
           loadData(params);
       }

       function edit(id) {
           alert(id);
       }

       function del(id) {
           alert(id);
       }

    </script>
</body>
</html>
html+js代码

点击分页,会往后台传两个默认的参数,page表示当前页索引,rows表示当前页大小(即每页多少行数据),其他参数在easyui的datagrid控件的queryParams属性中

 

2、后台代码,这里用的asp.net,如下:

public class PageController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public ActionResult GetPageData()
        {
            int pageIndex = Convert.ToInt32(HttpContext.Request.Form["page"]);
            int pageSize = Convert.ToInt32(HttpContext.Request.Form["rows"]);
            var name = HttpContext.Request.Form["name"];
            Dictionary<string, string> dic = new Dictionary<string, string>();
            if(!string.IsNullOrEmpty(name))
            {
                dic.Add("Name",name);
            }
            
            int totalCount = 0;
            List<UserInfo> list = GetData(dic,pageIndex, pageSize, out totalCount);

            return Json(new { total = totalCount, rows = list }, JsonRequestBehavior.AllowGet);
        }

        private List<UserInfo> GetData(Dictionary<string, string> dic,int pageIndex,int pageSize,out int totalCount)
        {
            List<UserInfo> list = new List<UserInfo>();
            UserInfo u = null;
            for (int i = 0; i < 55; i++)
            {
                u = new UserInfo();
                u.ID = 10000 + (i + 1);
                u.Number = "ZH" + (i + 1).ToString();
                u.Name = "Name" + (i + 1).ToString();
                list.Add(u);
            }

            if (dic != null && dic.Count > 0)
            {
                list = list.Where(x => x.Name.Contains(dic["Name"])).ToList();
            }

            totalCount = list.Count;
            list = list.Take(pageSize * pageIndex).Skip(pageSize * (pageIndex - 1)).ToList();
            return list;
        }

        public class UserInfo
        {
            public int ID { get; set; }
            public string Number { get; set; }
            public string Name { get; set; }
        }
    }
后台代码

后台会传json到前台,json中有两个参数,total表示数据源总数量,rows表示当前页的数据。

 

3、先看效果图:
