如何使用数组过滤数组数组？

如何针对数组（myNumbers）过滤数组数组（result）以仅获取result中每个数组中myNumbers中出现的值？

具体来说，给出：

var result = [02, 03, 04, 06, 07, 11, 12, 13];

var myNumbers = [
    [01, 03, 04, 05, 09, 10, 12, 14],
    [01, 03, 04, 05, 06, 08, 10, 12],
    [01, 02, 04, 05, 06, 08, 10, 12],
    [01, 03, 04, 05, 06, 09, 12, 13],
    [01, 02, 03, 05, 06, 08, 10, 11]
];

输出应该是：

[
    [03, 04, 12],
    [03, 04, 06, 12],
    [02, 04, 06, 12],
    [03, 04, 06, 12, 13],
    [02, 03, 06, 11],
]

我一次只能过滤一个数组：

// This only filters it for myNumbers[0]
var confereResult = result.filter(function (number) {
    if (myNumbers[0].indexOf(number) == -1)
            return number;
    console.log(number);
});

我如何通过整个列表呢？

您可以映射过滤的结果。

var filter = [02, 03, 04, 06, 07, 11, 12, 13],
    array = [[01, 03, 04, 05, 09, 10, 12, 14], [01, 03, 04, 05, 06, 08, 10, 12], [01, 02, 04, 05, 06, 08, 10, 12], [01, 03, 04, 05, 06, 09, 12, 13], [01, 02, 03, 05, 06, 08, 10, 11]],
    result = array.map(a => filter.filter(f => a.includes(f)));

console.log(result.map(a => a.join(' ')));

.as-console-wrapper { max-height: 100% !important; top: 0; }
