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 = ;
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 = ; i < ; i++)
{
u = new UserInfo();
u.ID = + (i + );
u.Number = "ZH" + (i + ).ToString();
u.Name = "Name" + (i + ).ToString();
list.Add(u);
} if (dic != null && dic.Count > )
{
list = list.Where(x => x.Name.Contains(dic["Name"])).ToList();
} totalCount = list.Count;
list = list.Take(pageSize * pageIndex).Skip(pageSize * (pageIndex - )).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:
