extjs 多维数组支持

1. 使用继承(extend)

 1 var model = Ext.define("Ext.data.reader.SomeModel", {
 2     extend: 'Ext.data.Model',
 3     fields: [
 4         {name: 'name'},
 5         {name: 'extra.gender'}
 6     ],
 7     get: function(field){
 8         if (field.indexOf('.') !== -1) {
 9             var parts = field.split('.');
10             var value = Ext.data.Model.prototype.get.call(this, parts[0]);
11 
12             return Ext.isObject(value) ? value[parts[1]] : undefined;
13         }
14         return Ext.data.Model.prototype.get.call(this, field);
15     }
16 })

2. 使用映射(mapping)

 {name: 'gender', mapping: 'extra.gender'}
