sencha如何从事件中获取数据

how sencha get data from event

我在视图中有一个列表,在其上声明侦听器。如何从事件中获取记录数据"itemdoubletap"?

查看我的代码:

{
    xtype: 'list',
    flex: 1,                            
    store: 'loanliststore',
    itemTpl: '贷款名:{loanname},描述:{loandesc}',

    listeners: {
        itemdoubletap: function(index, target, record, e, eOpts){
            console.log(record.get('loanname'));
            //the console said cant read the property 'get'
        }
    }
}

你缺少一个参数,更改:

function(index, target, record, e, eOpts)

收件人:

function(cmp, index, target, record, e, eOpts)
