javascript - 如何根据价格对数组中的对象进行排序

Question

如果我有这样的东西:

var lowestPricesCars =
{
  HondaC:
  {
    owner: "",
    price: 45156
  },
  FordNew:
  {
    owner: "",
    price:4100
  },
  HondaOld:
  {
    owner: "",
    price: 45745
  },
  FordOld:
  {
    owner: "",
    price: 34156
  },
}

如何根据价格订购汽车？

如果问题不清楚，请将其注释掉。

谢谢

Answer 1

const arrayOfKeys = Object.keys(lowestPricesCars)
const keysSortedByPrice = arrayOfKeys.sort((a,b) => {
  return lowestPricesCars[a].price - lowestPricesCars[b].price;
});
let carsSortedByPrice = {}
keysSortedByPrice.forEach(key => carsSortedByPrice[key] = lowestPricesCars[key])

如果要颠倒顺序:

return lowestPricesCars[b].price - lowestPricesCars[a].price;
