我如何使用for循环console.log shoppingCart数组中对象的name属性

Question

var shoppingCart = [{
  id: 0,
  name: 'Mens Shirt',
  price: 20,
  size: 'Large'
}, {
  id: 1,
  name: 'kids shirt',
  price: 15,
  size: 'small'
}]

Answer 1

您可以像这样简单地使用Array.prototype.forEach：

var shoppingCart = [{
  id: 0,
  name: 'Mens Shirt',
  price: 20,
  size: 'Large'
}, {
  id: 1,
  name: 'kids shirt',
  price: 15,
  size: 'small'
}]

shoppingCart.forEach(item => console.log(item.name));
