javascript - 通过仅包含数组属性子集的对象过滤javascript数组

我有一个具有许多属性的对象数组。我希望能够基于仅包含数组属性子集的过滤器对象找到匹配项。例如，我有一个客户

let Customer = {
    Name: "John Doe",
    Age: 80,
    Hair: "Red",
    Gender: "Male",

};

我有我的搜索对象:

let searchObject ={
    Hair: "Red",
    Gender: "Male"
}

我希望能够在数组中找到所有与searchObject匹配的客户，而不必这样做:

this.array.filter(z=>z.Hair == searchObject.Hair && z.Gender == searchObject.Gender);

我希望当searchObject添加更多属性时，它也会自动对这些属性进行过滤

最佳答案

您可以在内部的every()的Object.keys()上使用searchObject，并检查searchObject中的键的所有值是否与数组中对象的相应值匹配。

下面的代码段中，我有两个对象的Gender不同

let array = [{
    Name: "John Doe",
    Age: 80,
    Hair: "Red",
    Gender: "Male",
},{
    Name: "Marry",
    Age: 80,
    Hair: "Red",
    Gender: "Female",
}]

let searchObject ={
    Hair: "Red",
    Gender: "Male"
}

const res = array.filter(x => Object.keys(searchObject).every(k => x[k] === searchObject[k]));

console.log(res)
