JsonReader ArrayReader解析器的施用

Ext.onReady(function(){

	var fields=["id","name","email","sex","age"];// 字段的描述,指列
	
	
	
	
	var data=[["1","lang","lijun@126.com","0","20"],

	["4","lang","lijun@126.com","0","20"],
	["5","lang","lijun@126.com","0","20"]];// 行,与field一一匹配,本地数据取值方式
	
	// store表示数据存储器
	var store=new Ext.data.Store({
	
		//数据存储器的数据
		data:data,//data必须为数组，才能够实用arrayReader
		//参数id表示唯一标识,采用ArrayReader数组解析器解析
		reader:new Ext.data.ArrayReader({id:"id"},fields)
	})
	
	
	var cm=new Ext.grid.ColumnModel([{
	header:"id",// 列名
