关于Ext grid 数据源 Store问题之引用类型

Question

请问乍样在Store里面怎样解析引用类型type 谢谢各位 要求grid表格显示type.name的值gggggg

 

        var ds = Ext.data.Store({
            proxy:new Ext.data.HttpProxy({url:'../JSON/pankuSvr.getEquipment'}), //请求Seam注解方法
            reader:new Ext.data.JsonReader(
            {root:'results',totalProperty:'totalProperty'},
            [{name:'id'},
             {name:'test'},
             {name:'type'}] //引用类型 一个type实体类型,里面有id和name
            )，
            sortInfo:{field:'id',direction:'desc'}
        });
        var cm  = new Ext.grid.ColumnModel([
            {header:'ID',dataIndex:'id'},
            {header:'Test',dataIndex:'test'},
            {header:'Type',dataIndex:'type'} //此类型在页面上显示为Object用Firefox调试 发现type里面有id 和 name 值 :   "type":{"id":1,"name":"gggggg"}
        ]);
        var grid = new Ext.grid.GridPanel({
            id:'grid',
            store:ds,
            cm:cm
        })

ID	Test	type
1	测试数据1	object
2	测试数据2	object

var cm = new Ext.grid.ColumnModel([

{header:'ID',dataIndex:'id'},

{header:'Test',dataIndex:'test'},

{header:'Type',dataIndex:'type',
renderer:function(type){return:type.name;}
}
]);
