                    "id": 19347
    }]
    

需要的数据：

[{
                    
                    "type": "基金从业人员资格证",
                    "url": "Upload/UserCenter/20150303/2015030315252534569105.jpg",
                    "id": 19332
                },
                {
                 
                    "type": "基金从业人员资格证",
                    "url": "Upload/UserCenter/20150303/2015030315252534569105.jpg",
                    "id": 19347
    }]

Answer 1

var data = [{type: 1, url: 1, id: 1, a: 1}];
data.map(({type, url, id}) => {
    return {type, url, id};
});

var data = [{type: 1, url: 1, id: 1, a: 1}];
data.map(({type, url, id}) => ({type, url, id}));

两种写法其实一样，第一个种可读性好点，扩展性也好

Answer 2

var data = [ ... ];
data.map(function(v) {
    var obj = {};
    
    obj.type = v.type;
    obj.url = v.url;
    obj.id = v.id;
    
    return obj;
});

Answer 3

去看看 map 的用法
