I have an array of objects with category trees containing children arrays. Each category has a property disabled which may be true or false. I need to collect an array of all parents ids that has to be set disabled true if all of its bottom most children has disabled true.
[
{
Category: {
id: "69",
createdAt: "2022-05-24T09: 54: 27.104Z",
updatedAt: "2022-05-25T10: 36: 14.168Z",
name: "Jewelry",
key: "prykrasy",
description: "Прикраси",
disabled: false,
mpath: "69.",
children: [
{
Category: {
id: "70",
createdAt: "2022-05-24T09: 54: 27.109Z",
updatedAt: "2022-05-25T10: 36: 14.156Z",
name: "Accessories",
key: "aksesyary-dlya-prykras",
description: "Аксесуари для прикрас",
disabled: false,
mpath: "69.70.",
children: [
],
},
Category: {
id: "71",
createdAt: "2022-05-24T09: 54: 27.115Z",
updatedAt: "2022-05-25T10: 36: 14.156Z",
name: "Silver",
key: "bizhuteriya",
description: "Silver",
disabled: false,
mpath: "69.71.",
children: [
],
},
Category: {
id: "72",
createdAt: "2022-05-24T09: 54: 27.121Z",
updatedAt: "2022-05-25T10: 36: 14.168Z",
name: "jlewelry-stuff",
key: "uvelirni-vyroby",
description: "Ювелірні вироби",
disabled: true,
mpath: "69.72.",
children: [
]
}
}
]
}
}
]
I created a function to check the Category object for two things:
children?For case 1, it stores the id in a variable you can access. For case 2, it runs the same check for the children Category objects.
const allDisabled = []; // stores the ids
const checkChildren = (category) => {
let disabledCount = 0;
for (let i = 0; i < category.children.length; i++) {
const ctg = category.children[i].Category; // child category
if (ctg.disabled) {
disabledCount++;
}
if (ctg.children.length) {
checkChildren(ctg);
}
}
if (disabledCount === category.children.length) {
// all children are disabled
allDisabled.push(category.id);
}
}
Now you can run this function.
const categoriesArray = [...];
categoriesArray.forEach(item => checkChildren(item.Category));
