页面:

view plaincopy to clipboardprint?

<body>
<form id="form1" runat="server">
<table id="tt">
</table>
</form>
</body>

引用的JS:

view plaincopy to clipboardprint?

<link rel="stylesheet" type="text/css" href="http://www.cnblogs.com/script/themes/default/easyui.css" />
<link rel="stylesheet" type="text/css" href="http://www.cnblogs.com/script/themes/icon.css" />
<script type="text/javascript" src="http://www.cnblogs.com/script/jquery-1.4.2.min.js" </script>
<script type="text/javascript" src="http://www.cnblogs.com/script/jquery.easyui.min.js" </script>
<script type="text/javascript" src="http://www.cnblogs.com/script/locale/easyui-lang-zh_CN.js" mce_src="script/locale/easyui-lang-zh_CN.js"></script>

JS:

view plaincopy to clipboardprint?

<script type="text/javascript"><!--
$(function(){
$('#tt').datagrid({
width:810,
height:400,
idField:'xsbh',
url:'studentHandler.ashx',
singleSelect:true,
columns:[[
{field:'xsbh',title:'编号',width:80},
{field:'UserName',title:'姓名',width:100},
{field:'Sex',title:'性别',width:30},
{field:'SchoolYear',title:'年份',width:50},
{field:'opt',title:'操作',width:100,align:'center',
formatter:function(value,rec,index){
var s = '<a href="#" mce_href="#" onclick="view(\''+ rec.xsbh + '\')">查看</a> ';
var e = '<a href="#" mce_href="#" onclick="edit(\''+ rec.xsbh + '\')">编辑</a> ';
var d = '<a href="#" mce_href="#" onclick="del(\''+ index +'\')">删除</a> ';
return s+e+d;
}
}
]],
toolbar:[{
text:'增加',iconCls:'icon-add',handler:function(){
window.location.href='StuAdd.aspx';
}
},
{text:'导入',iconCls:'icon-add',handler:function(){
window.location.href='StuImport.aspx'
}
},
{text:'查找',iconCls:'icon-search'}
],
pagination:true
});
})
function view(bh) //转到查看页面
{
window.location.href='StuView.aspx?id='+bh+'&page=stu';
// var row = $('#tt').datagrid('getSelected');
// if(row)
// {
// alert(row.xsbh);
// }
}
function edit(bh) //转到编辑页面
{
window.location.href='StuEdit.aspx?id='+bh;
}
function del(index){ //删除操作
$.messager.confirm('确认','确认删除?',function(row){
if(row){
var selectedRow = $('#tt').datagrid('getSelected'); //获取选中行
$.ajax({
url:'delHandler.ashx?id='+selectedRow.xsbh+'&type=stu',
//加了个type，作用是以后不管什么删除，都可以转到这个ashx中处理
success:function(){alert('删除成功');}
});
$('#tt').datagrid('deleteRow',index);
}
})
}
// --></script>

这里面要注意的是，"操作"的跨行，一定要带上field:'opt',当然，field可以是任何值，这个值不用从数据库中绑定，随便取.如果没有field的话，会弹出 "rowspan为空或不是对象"的错误

获取数据和分页ashx:

view plaincopy to clipboardprint?

using System;
using System.Web;
using System.Data;
using System.Text;
public class studentHandler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
DataSet ds = new DataSet();
//点击datagrid的分页按钮，自动向后台发送2个参数,rows和page，代表每页记录数和页索引
int row = int.Parse(context.Request["rows"].ToString());
int page = int.Parse(context.Request["page"].ToString());
ds = GetContent(row, page);
string text =json.Dataset2Json(ds);
context.Response.Write(text);
}
private DataSet GetContent(int pagesize,int pageindex)
{
Graduate.BLL.Student bll = new Graduate.BLL.Student();
return bll.GetList(pagesize, pageindex);
}
public bool IsReusable {
get {
return false;
}
}
}

using System; using System.Web; using System.Data; using System.Text; public class studentHandler : IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "text/plain"; DataSet ds = new DataSet(); //点击datagrid的分页按钮，自动向后台发送2个参数,rows和page，代表每页记录数和页索引 int row = int.Parse(context.Request["rows"].ToString()); int page = int.Parse(context.Request["page"].ToString()); ds = GetContent(row, page); string text =json.Dataset2Json(ds); context.Response.Write(text); } private DataSet GetContent(int pagesize,int pageindex) { Graduate.BLL.Student bll = new Graduate.BLL.Student(); return bll.GetList(pagesize, pageindex); } public bool IsReusable { get { return false; } } }

删除ashx

view plaincopy to clipboardprint?

using System;
using System.Web;
using System.Web.SessionState;
public class delHandler : IHttpHandler,IRequiresSessionState {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
string id = context.Request["id"].ToString();
string type = context.Request["type"].ToString();
switch (type)
{
case "stu":
Graduate.BLL.Student stubll = new Graduate.BLL.Student();
stubll.Delete(id, HttpContext.Current.Session["username"].ToString(), HttpContext.Current.Session["usertype"].ToString());
break;
default:
break;
}
}
public bool IsReusable {
get {
return false;
}
}
}

using System; using System.Web; using System.Web.SessionState; public class delHandler : IHttpHandler,IRequiresSessionState { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "text/plain"; string id = context.Request["id"].ToString(); string type = context.Request["type"].ToString(); switch (type) { case "stu": Graduate.BLL.Student stubll = new Graduate.BLL.Student(); stubll.Delete(id, HttpContext.Current.Session["username"].ToString(), HttpContext.Current.Session["usertype"].ToString()); break; default: break; } } public bool IsReusable { get { return false; } } }

IRequiresSessionState 是因为用到了服务器端的session，没有用到的话可以去掉
