以下是从store中精确定位数据的几种方法：
var data = 
{
'rowCountFather': 3,
rowCountSon: 3,
'fatherData': [{
fatherId: 'father',
fatherName: '1',
fatherIconCls: 'manage'
}, {
fatherId: 'father',
fatherName: '2',
fatherIconCls: 'manage'
}, {
fatherId: 'father',
fatherName: '3',
fatherIconCls: 'manage'
}],
sonData: [{
sonId: 'son',
sonName: 'ho1',
sonIconCls: 'manage'
}, {
sonId: 'son',
sonName: 'ho2',
sonIconCls: 'manage'
}, {
sonId: 'son',
sonName: 'ho3',
sonIconCls: 'manage'
}]
};
var store = new Ext.data.JsonStore({
data: data,
autoLoad: true,
root: 'fatherData',
fields: ['fatherId', 'fatherName', 'fatherIconCls']
})
alert("data" + data.rowCountFather);
alert(store.reader.jsonData['rowCountFather']);
alert(store.getAt(0).get('fatherName'));
alert(store.reader.jsonData.fatherData[0].fatherName);
alert(store.reader.jsonData.sonData[0].sonName);
