 var grid = Ext.create('Ext.grid.Panel', {            renderTo: Ext.getBody(),            store: store,            height: 400,            width:800,            selModel: { selType: 'checkboxmodel' },   //选择框            columns: [                                              { text: '型录ID', dataIndex: 'cataId', align: 'left', maxWidth: 80 },                          { text: '型录编号', dataIndex: 'cataNo',  maxWidth: 120 },                          { text: '助记标题', dataIndex: 'cataTitle', align: 'left', minWidth: 80 },                          { text: '应用对象', dataIndex: 'cataObjectName', maxWidth: 80, align: 'left' },                                                  { text: '发布状态', dataIndex: 'cataPublishName', maxWidth: 80 },                          { text: '活动截止日期', dataIndex: 'cataEndDate',xtype:'datecolumn',dateFormat :'Y-m-d H:i:s' },                          { text: '更新时间', dataIndex: 'holyUpdateTime',xtype:'datecolumn',dateFormat :'Y-m-d H:i:s'},                          { text: '发布时间', dataIndex: 'catapushtime',xtype:'datecolumn',dateFormat :'Y-m-d H:i:s'}                       ],            bbar: [{                xtype: 'pagingtoolbar',                store: store,                displayMsg: '显示 {0} - {1} 条，共计 {2} 条',                emptyMsg: "没有数据",                beforePageText: "当前页",                afterPageText: "共{0}页",                displayInfo: true                             }],             listeners: { 'itemclick': function (view, record, item, index, e) {               Ext.MessageBox.alert("标题",record.data.cataId);            }            },             tbar:[             {text:'新增',iconCls:'a_add',handler:showAlert},"-",             {text:'编辑',iconCls:'a_edit2',handler:showAlert},"-",             {text:'停用/启用',iconCls:'a_lock'},"-",             {text:'发布',iconCls:'a_upload',handler:showAlert},"-",             {text:'组织型录',iconCls:'a_edit',handler:showAlert},"-",             {text:'管理商品',iconCls:'a_edit',handler:showAlert},"-",             "->",{ iconCls:"a_search",text:"搜索",handler:showAlert}],         });
function showAlert (){      var selectedData=grid.getSelectionModel().getSelection()[0].data;      Ext.MessageBox.alert("标题",selectedData.cataId); }
}); 


这个只能获取单行数据 
function showAlert (){             var selectedData=grid.getSelectionModel().getSelection()[0].data;             Ext.MessageBox.alert("标题",selectedData.cataId);         }
这个可以获取选择的多行数据
 var rows = grid.getView().getSelectionModel().getSelection();                var msg = "";                for (var i = 0; i < rows.length; i++) {                    msg = msg + rows[i].get('cataId') + ',';                }
