本文实例讲述了jquery easyui datagrid实现增加，修改，删除的方法。分享给大家供大家参考，具体如下：
页面:
<body> <form id="form1" runat="server"> <table id="tt"> </table> </form> </body>
引用的JS:
<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="http://www.jb51.netscript/jquery-1.4.2.min.js" </script> <script type="text/javascript" src="http://www.jb51.netscript/jquery.easyui.min.js" </script> <script type="text/javascript" src="http://www.jb51.netscript/locale/easyui-lang-zh_CN.js" mce_src="script/locale/easyui-lang-zh_CN.js"></script>
JS:
<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="#">查看</a> '; var e = '<a href="#" mce_href="#">编辑</a> '; var d = '<a href="#" mce_href="#">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:
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
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
希望本文所述对大家jQuery程序设计有所帮助。
