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
