如何使用lodash根據SQL IN子句等條件過濾數組？

Question

我正在嘗試使用 lodash 過濾數組中存在的數據。 我正在嘗試像 SQL IN 子句一樣過濾。

ex: - select * from Test where id IN (2,4,5,67); 

JSON：

storedData = [
    {
        "id" : 1,
        "name" : "ABC"
    },
    {
        "id" : 2,
        "name" : "XYZ"
    },
    {
        "id" : 3,
        "name" : "BVX"
    },
    {
        "id" : 4,
        "name" : "OOO"
    }
]

搜索條件：

[2,4,5,67]

所需輸出：

output = [
    {
        "id" : 2,
        "name" : "XYZ"
    },
    {
        "id" : 4,
        "name" : "OOO"
    }
]

下面是我試圖實現的代碼

output = _.filter(storedData, (value) => {
    return value.id == 2 || value.id == 4 || value.id == 5 || value.id == 67
});

你能幫我如何過濾 IN 子句嗎？

Answer 1

您可以使用intersectionWith找到兩個數組之間的intersectionWith ，這允許您提供回調並保留回調為其返回true的第一個數組中的所有元素。

請參閱下面的示例：

 const storedData = [ { "id" : 1, "name" : "ABC" }, { "id" : 2, "name" : "XYZ" }, { "id" : 3, "name" : "BVX" }, { "id" : 4, "name" : "OOO" } ]; const search = [2,4,5,67]; const res = _.intersectionWith(storedData, search, (o, n) => o.id === n); console.log(res);

Answer 2

使用.includes

_.filter(storedData, (value) => _.includes(criteria, value.id))

 const storedData = [ { id: 1, name: "ABC", }, { id: 2, name: "XYZ", }, { id: 3, name: "BVX", }, { id: 4, name: "OOO", }, ] const criteria = [2, 4, 5, 67] const output = _.filter(storedData, (value) => _.includes(criteria, value.id)) console.log(output)
