javascript - 如何在javascript中检查对象的属性数组是否为空

Question

我正在尝试在 js 中进行验证以检查对象的属性数组是否为空字符串，为了澄清更多，我有一个内部包含对象的数组，我想检查每个对象是否为空属性(“”)，这是我写的代码，但我不确定这是正确的方法

const items = [
  { name: "something", quantity: "25", unit: "d" },
  { name: "something", quantity: "25", unit: "d" },
  { name: "something", quantity: "25", unit: "d" },
];

const validation = items.map((item) => {
  return Boolean(item.name && item.quantity && item.unit);
});

但它只是给了我一个这样的数组:

[true, true, true]

如果所有属性都不为空，就像我希望它只给我值 true

谢谢

你可以拿 Array#every

The every() method tests whether all elements in the array pass the test implemented by the provided function. It returns a Boolean value.

并获取 true如果所有值都不是假的。

const items = [
  { name: "something", quantity: "25", unit: "d" },
  { name: "something", quantity: "25", unit: "d" },
  { name: "something", quantity: "25", unit: "d" },
];

const validation = items.every(item => item.name && item.quantity && item.unit);

console.log(validation);
