请问如何遍历一个对象 判断每个属性值是否为0？

Question

let obj = {
    area: 0,
    business_license_imgs: 0,
    business_place_imgs: 0,
    company_name: 0,
    contact_name: 1,
    customer_type: 0
}

是对象，不是数组，请问怎么快速判断每个属性值是否为0

Answer 1

Object.values(obj).every(n => n === 0);

Answer 2

1.用 for...in 循环：

let isAllZero = true;
for (let key in obj) {
  if (obj[key] !== 0) {
    isAllZero = false;
    break;
  }
}

2.用 Object.entries：

const isAllZero = Object.entries(obj).every(([key, value]) => value === 0);

3.用 Object.keys：

const isAllZero = Object.keys(obj).every(key => obj[key] === 0);

Answer 3

使用Object.values() + every可以判断

Object.values(obj).every(item => item === 0)
