Javascript 在另一个数组中查找数组并获取结果的索引

我有这个阵列：

    var arr = [
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Nessuno"}, {name: "Tegole", slug: "tegole", option: "Senza Tegole"}], id:430, price:"1000"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Nessuno"}, {name: "Tegole", slug: "tegole", option: "Rossi"}], id:431, price:"1025"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Nessuno"}, {name: "Tegole", slug: "tegole", option: "Verdi"}], id:432, price:"1025"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Trasparente"}, {name: "Tegole", slug: "tegole", option: "Senza Tegole"}], id:433, price:"1100"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Trasparente"}, {name: "Tegole", slug: "tegole", option: "Rossi"}], id:434, price:"1125"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Trasparente"}, {name: "Tegole", slug: "tegole", option: "Verdi"}], id:435, price:"1125"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Noce"}, {name: "Tegole", slug: "tegole", option: "Senza Tegole"}], id:436, price:"1100"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Noce"}, {name: "Tegole", slug: "tegole", option: "Rossi"}], id:437, price:"1125"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Noce"}, {name: "Tegole", slug: "tegole", option: "Verdi"}], id:438, price:"1125"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Castagno"}, {name: "Tegole", slug: "tegole", option: "Senza Tegole"}], id:439, price:"1100"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Castagno"}, {name: "Tegole", slug: "tegole", option: "Rossi"}], id:440, price:"1125"},
{attributes: [{name: "Impregnante", slug: "impregnante", option: "Castagno"}, {name: "Tegole", slug: "tegole", option: "Verdi"}], id:441, price:"1125"}]

和另一个阵列：

var obj =  [{name: "Impregnante", slug: "impregnante", option: "Trasparente"}, {name: "Tegole", slug: "tegole", option: "Rossi"}];

有人能给我一个建议，如何在arr中找到obj并返回obj所在的id。。。 提前和Thx等抱歉的语言

尝试以下操作：

const parseData = (arr, obj) => {
  let found = arr.find(a => JSON.stringify(a.attributes) === JSON.stringify(obj));
  return found ? found.id : null;
}

console.log(parseData(arr, obj)); //434

---

为了提供对象比较，我使用了

JSON.stringify（）

。这种方法要求对操作中涉及的对象的属性进行严格的排序。如果此要求不可接受，您可以通过其他方式进行比较。

我认为这可以帮助您：

获取对象：

var arrFilter = arr.filter(function(a, b){ return JSON.stringify(a.attributes) == JSON.stringify(obj) });

// if you need the property ID
arrFilter[0].id

获取索引：

var idx = arr.findIndex(function(a, b){ return JSON.stringify(a.attributes) == JSON.stringify(obj) })

---

如果需要，可以使用箭头函数（Lambda表达式）。

Thx，它工作得很好，但是，如果我有像var obj2=[{option:“Trasparente”}，{option:“Rossi”}]这样的数组怎么办？只需进行严格的比较：

let found=arr.find（a=>a.attributes[0]。option==obj[0]。option&&a.attributes[1]。option==obj[1]。option）--根据您的需要，比较器可以定制成100种方式，解决方案很简单，但我对这种编程语言非常熟悉。又来了！
