javascript - js 中是否有类似 'lies in' 运算符的内容，因为我们在 mongoose/mongo 中有 '$in'

Question

我想在js中实现这样的功能

            function(arrayOfObjects, arrayOfValues, property) {

/*here i want to return all the objects of 'arrayOfObjects' 
        which satisfies the following condition 
        (index is the iterative index of array 'arrayOfObjects')
               arrayOfObjects[index][property] is equivalent to any of
    the values that lies in arrayOfValues */

            };

示例:

arrayOfObjects = [{ a: 1, b: 2 }, { a: 3, b:4 }, { a: 1, b :3 }];
arrayOfValues = [ 2, 3 ];

function(arrayOfObjects, arrayOfValues, 'b')

应该返回 [{ a: 1, b: 2 }, { a: 1, b :3 }]

Answer 1

arrayOfObjects.filter(function (elem) {
    return elem.hasOwnProperty(property)
        && -1 !== arrayOfValues.indexOf(elem[property]);
});
