我想简化一个对象数组.我们假设我有以下数组:

var users = [{
    name: 'John',
    email: 'johnson@mail.com',
    age: 25,
    address: 'USA'
    },
    {
        name: 'Tom',
        email: 'tom@mail.com',
        age: 35,
        address: 'England'
    },
    {
        name: 'Mark',
        email: 'mark@mail.com',
        age: 28,
        address: 'England'
}];

并过滤对象:

var filter = {address: 'England', name: 'Mark'};

例如,我需要按地址和名称过滤所有用户,所以我循环过滤器对象属性并检查出来:

function filterUsers (users, filter) {
    var result = [];
    for (var prop in filter) {
        if (filter.hasOwnProperty(prop)) {

            //at the first iteration prop will be address
            for (var i = 0; i < filter.length; i++) {
                if …
