页面:

view plaincopy to clipboardprint?
01.<body>
02.    <form id="form1" runat="server">
03.    <table id="tt">
04.
05.    </table>
06.
07.
08.    </form>
09.</body>
<body>
    <form id="form1" runat="server">
    <table id="tt">

    </table>


    </form>
</body>

引用的JS:

view plaincopy to clipboardprint?
01.<link rel="stylesheet" type="text/css" href="../../script/themes/default/easyui.css" />
02.    <link rel="stylesheet" type="text/css" href="../../script/themes/icon.css" />
03.    <script type="text/javascript" src="../../script/jquery-1.4.2.min.js" </script>
04.    <script type="text/javascript" src="../../script/jquery.easyui.min.js" </script>
05.    <script type="text/javascript" src="../../script/locale/easyui-lang-zh_CN.js" mce_src="script/locale/easyui-lang-zh_CN.js"></script>
<link rel="stylesheet" type="text/css" href="../../script/themes/default/easyui.css" />
    <link rel="stylesheet" type="text/css" href="../../script/themes/icon.css" />
    <script type="text/javascript" src="../../script/jquery-1.4.2.min.js" </script>
    <script type="text/javascript" src="../../script/jquery.easyui.min.js" </script>
    <script type="text/javascript" src="../../script/locale/easyui-lang-zh_CN.js" mce_src="script/locale/easyui-lang-zh_CN.js"></script>

JS:

view plaincopy to clipboardprint?
01.<script type="text/javascript"></script>
<script type="text/javascript"></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?
01.using System;
02.using System.Web;
03.using System.Data;
04.using System.Text;
05.
06.public class studentHandler : IHttpHandler {
07.
08.    public void ProcessRequest (HttpContext context) {
09.        context.Response.ContentType = "text/plain";
10.        DataSet ds = new DataSet();
11.        //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
12.        int row = int.Parse(context.Request["rows"].ToString());
13.        int page = int.Parse(context.Request["page"].ToString());
14.        ds = GetContent(row, page);
15.        string text =json.Dataset2Json(ds);
16.        context.Response.Write(text);
17.    }
18.
19.    private DataSet GetContent(int pagesize,int pageindex)
20.    {
21.        Graduate.BLL.Student bll = new Graduate.BLL.Student();
22.        return bll.GetList(pagesize, pageindex);
23.    }
24.    public bool IsReusable {
25.        get {
26.            return false;
27.        }
28.    }
29.
30.}
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?
01.using System;
02.using System.Web;
03.using System.Web.SessionState;
04.
05.public class delHandler : IHttpHandler,IRequiresSessionState {
06.
07.    public void ProcessRequest (HttpContext context) {
08.        context.Response.ContentType = "text/plain";
09.        string id = context.Request["id"].ToString();
10.        string type = context.Request["type"].ToString();
11.        switch (type)
12.        {
13.            case "stu":
14.                Graduate.BLL.Student stubll = new Graduate.BLL.Student();
15.                stubll.Delete(id, HttpContext.Current.Session["username"].ToString(), HttpContext.Current.Session["usertype"].ToString());
16.                break;
17.            default:
18.                break;
19.        }
20.    }
21.
22.    public bool IsReusable {
23.        get {
24.            return false;
25.        }
26.    }
27.
28.}
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
