javascript - 在数组对象中查找一个值并使用该对象中的另一个值

Question

找不到正确的工作流程来从循环数组中获取以下内容:

• 遍历数组中的所有对象并找到特定的 warehouse 值
• 如果该值存在于任何对象中，则使用包含特定 warehouse 值的对象并返回其中的 price 值

例如:如果我搜索 1374610389 仓库值(value)，我会得到返回价格 78.00

var test = [
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "10.00",
    warehouse: 1157964289
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "22.00",
    warehouse: 1269753487
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "78.00",
    warehouse: 1374610389
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "32.00",
    warehouse: 1674985630
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "16.00",
    warehouse: 1847893458
  }
]

Answer 1

The find() method returns a value of the first element in the array that satisfies the provided testing function.

您可以使用 find 方法:

test.find(obj => obj.warehouse == '1374610389').price

var test = [
    {
    lorem: "ipsum",
    dolor: "sit",
    price: "10.00",
    warehouse: 1157964289
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "22.00",
    warehouse: 1269753487
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "78.00",
    warehouse: 1374610389
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "32.00",
    warehouse: 1674985630
  },
  {
    lorem: "ipsum",
    dolor: "sit",
    price: "16.00",
    warehouse: 1847893458
  }
]

console.log( test.find(obj => obj.warehouse == '1374610389').price);
