Ext.onReady(function() { store3 = new Ext.data.JsonStore({ autoDestroy: true, totalProperty : 'totle', url: 'service.do', storeId: 'myStore', root: 'data', fields : [ 'id', "name", "pw" ] }); var pagingToolbar = new Ext.PagingToolbar({ emptyMsg : "没有数据", displayInfo : true, displayMsg : "显示从{0}条数据到{1}条数据，共{2}条数据", store : store3, pageSize : 50 }); var grade = new Ext.grid.GridPanel({ title : "数据列表", store : store3, height : 300, bbar : pagingToolbar, columns : [ { header : "id", dataIndex : "id", width : 300 }, { header : "name", dataIndex : "name", width : 300 }, { header : "pw", dataIndex : "pw" } ], region : 'center' }); var panel = new Ext.Viewport({ layout : 'border', items : [ grade ] }); });
