我有以下数组：
const arr1 = [
{"id": 699306, "address": "On earth" },
{"id": 701298, "address": "On earth" },
{"id": 701299, "address": "On earth" },
{"id": 701300, "address": "On earth" }
];
另一个数组非常复杂，如下所示：
const arr2 = [

所以我想要的是将两个数组合并为一个，如下所示：
const arr1 = [
{"id": 699306, "address": "On earth", "included": [items from arr2], "excluded": [items from arr2] },
{"id": 701298, "address": "On earth", "included": [items from arr2], "excluded": [items from arr2] },
{"id": 701299, "address": "On earth", "included": [], "excluded": [] }, //As there is no matching for these ids
{"id": 701300, "address": "On earth", "included": [], "excluded": [] }
];
我知道，这种关系看起来不合适，但这就是我现在的情况。有什么办法可以映射它们吗？
我尝试了以下操作，但它对于包含和排除对象都返回 null：
mapArraysById(array1: Item[], array2: Item[]): Item[] {
const mergedArray: Item[] = [];
for (let i = 0; i < array1.length; i++) {
const item1 = array1[i];
console.log("id: " + item1.id);
const item2 = array2.find(item => item.id === item1.id);
if (item2) {
console.log("Item 2:");
console.log(item1 + " " + item2);
mergedArray.push({ ...item1, ...item2 });
} else {
mergedArray.push({ ...item1, included: [], excluded: [] });
}
}
return mergedArray;
}
尝试迭代
arr1arr2参考以下代码参考：
const arr1 = [
{ id: 699306, address: "On earth" },
{ id: 701298, address: "On earth" },
{ id: 701299, address: "On earth" },
{ id: 701300, address: "On earth" },
];
const arr2 = [
{
included: [
{
id: 699306,
levelColumn: "CLAIM_DATE",
levelColumnName: "Claims",
isIncluded: true,
tabs: [{ tabId: 1231, tabName: "Files" }],
levels: [
{ permValue: "01/01/2021", permName: "01/01/2021" },
{ permValue: "01/01/2022", permName: "01/01/2022" },
],
},
{
id: 701298,
levelColumn: "CLAIM_DATE",
levelColumnName: "Claims",
isIncluded: true,
tabs: [{ tabId: 1231, tabName: "Files" }],
levels: [
{ permValue: "01/01/2021", permName: "01/01/2021" },
{ permValue: "01/01/2022", permName: "01/01/2022" },
],
},
],
excluded: [
{
id: 368302,
levelColumn: "E1_APP_USER_ID",
levelColumnName: "User",
isIncluded: false,
tabs: [{ tabId: 1971, tabName: "Users" }],
levels: [
{ permValue: "575301", permName: " Kelley Mahowald (kmahowald [575301])" },
],
},
],
},
];
const mergeArrays = (arr1, arr2) => {
const { included, excluded } = arr2[0]; // get included and excluded from arr2
return arr1.map(item => {
const includedItems = included.filter(i => i.id === item.id); // get matching included items
const excludedItems = excluded.filter(e => e.id === item.id); // get matching excluded items
return {
...item,
included: includedItems.length > 0 ? includedItems : [],
excluded: excludedItems.length > 0 ? excludedItems : [],
};
});
};
console.log(JSON.stringify(mergeArrays(arr1, arr2)));
