1、首先定义对象:
Ext.define('log',{ extend:'Ext.data.Model', fields:[ {name: 'id',mapping:'id'}, {name: 'user'}, {name: 'type'}, {name: 'time'}, {name: 'describe'} ] }); 2、定义Store:
var logStore=Ext.create('Ext.data.Store', { pageSize:rowNum, model:'log',//对象 remoteSort:true, proxy: { type:'ajax', actionMethods:{read:'POST'},//提交方式。post和get url: 'log.htm?show', extraParams:{//提交时传递的参数 startTime:"", endTime:"" },
reader: { totalProperty: 'totalRows',//分页数据,总条数 root: 'data'//分页list }, simpleSortMode :true }, sorters:[{ property:'id',//排序 direction:"ASC" }] });
3、定义grid:
var logGrid = Ext.create('Ext.grid.Panel',{ columnLines: true, width: '100%', id: 'logGrid', bbar: Ext.create('Ext.PagingToolbar', {//分页工具栏 store: logStore, id: 'pagger', displayInfo: true, displayMsg: '显示第 {0} 条到 {1} 条记录,一共 {2} 条', emptyMsg: "没有数据" }), viewConfig: { stripeRows: true }, tbar: [{}], columns:[//表头 {xtype: 'rownumberer',text:'序号',width:35,align:'left'}, {header: 'ID',width: 70,dataIndex: 'id',id: 'id',hidden: true,menuDisabled: true}, {header: '类别',width: 200,dataIndex: 'type',id: 'type',menuDisabled: false}, {header: '时间',width: 200,dataIndex: 'time',id: 'time',menuDisabled: true}, {header: '操作人',width: 200,dataIndex: 'user',id: 'user',menuDisabled: true}, {header: '描述',width: 200,dataIndex: 'describe',id: 'describe',menuDisabled: true} ], forceFit : true,//列自动扩展宽度 store: logStore, autoScroll: true, stripeRows: true }); logStore.load({params:{start:1,limit:10}});//加载数据 //logStore.loadPage(1);//这样也行
