我只是在很短的时间里编程，但是我面对的是一个难以理解的数据结构。我有一个函数，可以获取一组对象，表示添加到购物车中的产品。
getAllAddedItems(addedItems) {
this.fullInfoAddedItems.push(addedItems);
const filtered = this.fullInfoAddedItems.reduce((filtered, item) => {
if ( !filtered.some(filteredItem => JSON.stringify(filteredItem) === JSON.stringify(item)) ) {
filtered.push(item);
}
return filtered;
}, []);
this.fullInfoAddedItems = filtered;
}
结果，我得到以下对象数组
[
{
"price": 0,
"functional_id": "carnet_de_conventions",
"quantity": 3
},
{
"price": 0,
"functional_id": "depliants_services_incinération",
"quantity": 4
}
]
问题是，我需要嵌套对象数组中的数据“名称”以完成视图信息。
这将是数组的结构

[我附加了一个stacblitz链接，通过“ functional_id”来模拟我要进行比较的操作，以从嵌套对象数组中获取“名称”并推送到第一个数组
https://stackblitz.com/edit/angular-ivy-3wfgme
有人给我一个有效的选择。预先谢谢你。
我想做的是遍历第二个数组，将原始产品的“ functional_id”与添加到第一个数组中的产品的“ functional_id”进行比较，因此我可以在第一个数组中提取“ name”，然后推入第一个数组
this.market.forEach(function(item: any, i) {
item.products.forEach(function(products: any, i) {
products.items.forEach(function(sale: any, i) {
let saleId = sale.functional_id;
console.log(sale);
console.log(saleId);
});
});
});
这是我想要做的，但是我看不到如何比较两个数组
addedItems数组，并对该数组中的每个项目，迭代products数组内的每个对象中的product数组，并检查当前items数组内的任何项目是否具有functional_id等于functional_id数组中当前项目的addedItemsgetAllAddedItems(addedItems) {
addedItems.forEach(item => {
this.product.forEach(({products}) => {
products.forEach(({name, items}) => {
const index = items.findIndex(i => i.functional_id === item.functional_id);
if (index > -1) item.name = name;
})
})
})
console.log(addedItems);
}
这里是stackblitz demo。打开控制台以查看功能的输出
for (var j = 0; j <= nestedArray.length - 1; j++) {
for (var k = 0; k <= nestedArray[j]['products'].length - 1; k++) {
for (var i = 0; i <= inputArray.length - 1; i++) {
let pos = nestedArray[j]['products'][k]['items'].map(ele => ele.functional_id).indexOf(inputArray[i]['functional_id']);
if (pos != -1) {
inputArray[i]['name'] = nestedArray[j]['products'][k]['name'];
}
}
}
}
