如何过滤对象数组 Javascript 中的数组对象？

Question

我正在尝试按产品

筛选列表

const questions = [
    { "id": 2616, "offerings": [{"code": "AA"},{"code": "AB"}]},
    { "id": 1505, "offerings": [{"code": "AA"},{"code": "ABC"}]},
    { "id": 1500, "offerings": [{"code": "AC"},{"code": "DC"}]}
];

const filterByArray = ['AB', 'DC'];

我的预期结果是根据 filterByArray

中传递的内容取回所有数组元素

[
    { "id": 2616, "offerings": [{"code": "AA"},{"code": "AB"}]},
    { "id": 1500, "offerings": [{"code": "AC"},{"code": "DC"}]}
]

我尝试使用

过滤数组

var filtered = questions.filter(function(element) {
    return element.offerings.filter(function(cd) {
       return filterByArray.indexOf(cd.code) > -1;
    }).length === filterByArray.length;
});

console.log(filtered)

但这会一直返回所有数组元素。

使用Array.some() and Array.includes().

const questions = [
    { "id": 2616, "offerings": [{"code": "AA"},{"code": "AB"}]},
    { "id": 1505, "offerings": [{"code": "AA"},{"code": "ABC"}]},
    { "id": 1500, "offerings": [{"code": "AC"},{"code": "DC"}]}
];

const filterByArray = ['AB', 'DC'];

const output = questions.filter(q => q.offerings.some(o => filterByArray.includes(o.code)));

console.log(output);
