js依据某一个值或者某一个数组过滤出对象数组中符合条件的汇合,利用filter和includes:

案例1:

    const target = [{a: [1, 2, 3]}, {a: [11, 22, 31]}, {a: [9, 7, 3]}];    const tempSpecId = 3;    const selectedArray = target.filter((item) => {      return item.a.includes(tempSpecId)    });    console.log(selectedArray, 'selectedArray-')    // [{a: [1, 2, 3]}, {a: [9, 7, 3]}]

案例2:

    const specIds = [1, 2, 3, 4];    const productList = [{a: 1}, {a: 22}, {a: 3}];    const selectedArray = productList.filter(item => {      return !specIds.includes(item.a)    });    console.log(selectedArray, 'selectedArray')    // [{a: 22}]
