Question

如果我要查找的值在对象数组中，我希望javascript返回true

下面是数组数据

[
{
holdings: [
{ product: { id: 1, prodName: 'LX세미콘', prodCode: '108320' } },
{ product: { id: 2, prodName: '컴투스', prodCode: '078340' } }
]
},
{
holdings: [ { product: { id: 1, prodName: 'LX세미콘', prodCode: '108320' } } ]
}
]

如果产品的produccode为"108320"，我想返回true。

我试着

Answer 1

您可以使用Array.prototype.some:

const data = [
{
holdings: [
{ product: { id: 1, prodName: 'LX세미콘', prodCode: '108320' } },
{ product: { id: 2, prodName: '컴투스', prodCode: '078340' } }
]
},
{
holdings: [ { product: { id: 1, prodName: 'LX세미콘', prodCode: '108320' } } ]
}
]

function present(code, data) {
return data.some(item =>
item.holdings.some(holding =>
holding.product.prodCode === code
)
)
}
console.log(present('108320', data));
