如何通过JS中的内部键引用Obj

Question

Lets say I have an array of objects: 可以说我有一个对象数组：

inventory = [{name:'milk',price:4},{name:'apple',price:2}]

How could I reference the entire object that contains inventory.name = 'milk' or inventory.price = 4? 我如何才能引用包含清单。名称=“牛奶”或清单。价格= 4的整个对象？

I need to reference it in order to return its index inside of the outer array. 我需要引用它才能在外部数组中返回其索引。

Answer 1

There are several ways, but the first is: 有几种方法，但是第一种是：

const obj = inventory.find(object => object.name === "milk" || object.price === 4)

or you can use findIndex 或者您可以使用findIndex

Answer 2

Seems like you are looking for Array#findIndex : 似乎您正在寻找Array#findIndex ：

const index = inventory.findIndex(item => item.name === 'milk');

Or use Array#find if you want the actual object. 或者，如果需要实际对象，请使用Array#find 。
