Javascript多个过滤器数组 [英] Javascript multiple filters array

问题描述

我的问题是对该问题的扩展 javascript过滤器数组多个条件
从这个问题开始，如果过滤器对象是

My question is extension to this question javascript filter array multiple conditions
from that question if filter object is

{地址:'England'，名称:'Mark'};

并且数组为

var users = [{
    name: 'John',
    email: '[e-mail]',
    age: 25,
    address: 'USA'
  },
  {
    name: 'Tom',
    email: '[e-mail]',
    age: 35,
    address: 'England'
  },
  {
    name: 'Mark',
    email: '[e-mail]',
    age: 28,
    address: 'England'
  }
];

所以答案是

[
  {
    "name": "Mark",
    "email": "[e-mail]",
    "age": 28,
    "address": "England"
  }
]

这绝对好，但我的问题是必须为过滤器对象属性值过滤数组
例如我的过滤器对象将是 {address:'England'，name:''} ，现在它必须为所有名称和地址England

which is absolutely fine but my question is array has to be filtered for the filter object properties value
for example my filter object will be {address: 'England', name: ''} now this has to filter the array for all names and address England

推荐答案

您将对用户以及每个过滤器对象的条目使用过滤器

You'd use filter on users and every on the filter object's entries

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

const res = users.filter(user => 
  Object.entries(filter)
  .every(([k,v]) => v === '' || user[k] === v)
);
console.log(res);

<script>
var users = [{
  name: 'John',
  email: '[e-mail]',
  age: 25,
  address: 'USA'
},
  {
    name: 'Tom',
    email: '[e-mail]',
    age: 35,
    address: 'England'
  },
  {
    name: 'Mark',
    email: '[e-mail]',
    age: 28,
    address: 'England'
  }
];
</script>
