我想用单个对象检查数组内的条件。
let arr = [
{
name: "john",
description: {
height: 5.5,
weight: 54,
},
},
{
name: "mary",
description: {
height: 5.8,
weight: 65,
},
},
{
name: "smith",
description: {
height: 6.1,
weight: 85,
},
},
];
let obj = {
height: 5.8,
weight: 65,
};
我想比较数组中的obj，如果它匹配一个，我想获取名称。例如，obj等于结婚。我想印玛丽。这就是我尝试过的。
let result = arr.filter((item) => item.description === obj )
console.log(result.name);
您可以使用对象的条目构建过滤器，并迭代所有条目并检查值。然后映射名称。
let array = [{ name: "john", description: { height: 5.5, weight: 54 } }, { name: "mary", description: { height: 5.8, weight: 65 } }, { name: "smith", description: { height: 6.1, weight: 85 } }],
object = { height: 5.8, weight: 65 },
filters = Object.entries(object),
result = array
.filter(({ description }) => filters.every(([key, value]) => description[key] === value))
.map(({ name }) => name);
console.log(result);本文收集自互联网，转载请注明来源。
