ext json数据的读取

huangdh12 2010-01-16 09:49:39





Ext.onReady(function(){

	var data={

		totalcount:10,

		root:[

		{name:'name1',id:'id1',sex:'sex1'},

		{name:'name2',id:'id2',sex:'sex2'},

		{name:'name3',id:'id3',sex:'sex3'},

		{name:'name4',id:'id4',sex:'sex4'},

		{name:'name5',id:'id5',sex:'sex5'},

		{name:'name6',id:'id6',sex:'sex6'},

		{name:'name7',id:'id7',sex:'sex7'},

		{name:'name8',id:'id8',sex:'sex8'},

		{name:'name9',id:'id9',sex:'sex9'},

		{name:'name10',id:'id10',sex:'sex10'}

		]

	};

	var reader = new Ext.data.JsonReader(

	{root:'root'},[

	{name:'name'},

	{name:'id'},

	{name:'sex'}

	]	

	);

	

	var proxy = new Ext.data.MemoryProxy(data);

	

	var store = new Ext.data.Store({

		proxy: proxy,

		reader:reader

	});

	

	var cm = new Ext.grid.ColumnModel([

	{header:'名字',dataIndex:'name'},

	{header:'id号',dataIndex:'id'},

	{header:'性别',dataIndex:'sex'},

	]);

	

	var grid = new Ext.grid.GridPanel({

		store:store,

		cm:cm,

		autoHeight : true

	});

	grid.render('hello');	

});

为何我这样数据读取不了？
json数据应该用什么proxy？
