从对象内的对象数组中删除对象

Question

I am not sure how to form this question, but I will do my best. I want to remove an object from an array produits that is inside the parent object, depending on the families.name that must equal a string from the initial object that I want to delete ( I already achieved this part).

Right now I'm stuck and don't know how to update the initial Parent object, I was able to delete the object from the array produits.

The parent Object:

let Parent = {
    "Id": "60f03c42a512e04c4b0161e7",
    "familles": [{
            "name": "LOV D+",
            "parent": "QB",
            "produits": [{
                    "uid": "ITEM-20210715-20758",
                    "type": "fabricant",
                    "parent_uid": null,
                    "version_application": "1.1.0",
                    "creation_date": null,
                    "titu": "REST1",
                    "ref_cstb": "162367462",
                    "gamme": "SUPERGRES",
                    "serie": "PREMIERE",
                    "description": "300x300 - 20 - Blue",
                    "usines": null
                },
                {
                    "uid": "QB32N-20210720-75584",
                    "type": "fabricant",
                    "parent_uid": null,
                    "version_application": "1.1.0",
                    "creation_date": "2021-07-20T14:34:04.49Z",
                    "titu": "REST1",
                    "ref_cstb": "ref-18-taieb",
                    "gamme": "SUPERGRES T_20",
                    "serie": "WIND",
                    "description": null,
                    "usines": null
                }
            ],
            "version_schema": null
        },
        {
            "name": "LOV F+",
            "parent": "QB",
            "produits": [{
                "uid": "ITEM-20210720-33547",
                "type": "fabricant",
                "parent_uid": null,
                "version_application": "1.1.0",
                "creation_date": "2021-07-20T14:46:37.649Z",
                "titu": "REST1",
                "ref_cstb": "ref19-taieb",
                "gamme": "SUPERGRES T_20",
                "serie": "STOCKHOLM",
                "description": null,
                "usines": null
            }],
            "version_schema": null
        }
    ]
}

The object I want to delete

let obj1 = {
    "uid": "ITEM-20210715-20758",
    "type": "fabricant",
    "parent_uid": null,
    "version_application": "1.1.0",
    "creation_date": null,
    "titu": "REST1",
    "ref_cstb": "162367462",
    "gamme": "SUPERGRES",
    "serie": "PREMIERE",
    "description": "300x300 - 20 - Blue",
    "usines": null,
    "group": "QB - LOV D+",
    "parent": "QB"
}

So that my Parent Object will look like this

let Parent = {
    "Id": "60f03c42a512e04c4b0161e7",
    "familles": [{
            "name": "LOV D+",
            "parent": "QB",
            "produits": [{
                "uid": "ITEM-20210720-75584",
                "type": "fabricant",
                "parent_uid": null,
                "version_application": "1.1.0",
                "creation_date": "2021-07-20T14:34:04.49Z",
                "titu": "REST1",
                "ref_cstb": "ref-18-taieb",
                "gamme": "SUPERGRES T_20",
                "serie": "WIND",
                "description": null,
                "usines": null
            }],
            "version_schema": null
        },
        {
            "name": "LOV F+",
            "parent": "QB",
            "produits": [{
                "uid": "ITEM-20210720-33547",
                "type": "fabricant",
                "parent_uid": null,
                "version_application": "1.1.0",
                "creation_date": "2021-07-20T14:46:37.649Z",
                "titu": "REST1",
                "ref_cstb": "ref19-taieb",
                "gamme": "SUPERGRES T_20",
                "serie": "STOCKHOLM",
                "description": null,
                "usines": null
            }],
            "version_schema": null
        }
    ]
}

What I have so far done:

    Remove(obj, parentObj) {

        let a = e.group.split("-").pop().slice(1)
        console.log(a) // Will Display LOV D+ 
        let newArray = this.certificat.familles.find((x: {
            name: any;
        }) => x.name === a); // Will display the proper object that have the name = LOV D+
        newArray = newArray.produits.filter(({
            uid
        }) => {
            return uid !== e.uid;
        }); // This will delete the object from the array, but it will not update the parent object, I'm missing something here 
    }

Remove(obj1, parent)

Answer 1

Here you go. This will splice the object with matching name and uid from Parent , like you want.

 let Parent = { "Id": "60f03c42a512e04c4b0161e7", "familles": [{ "name": "LOV D+", "parent": "QB", "produits": [{ "uid": "ITEM-20210715-20758", "type": "fabricant", "parent_uid": null, "version_application": "1.1.0", "creation_date": null, "titu": "REST1", "ref_cstb": "162367462", "gamme": "SUPERGRES", "serie": "PREMIERE", "description": "300x300 - 20 - Blue", "usines": null }, { "uid": "QB32N-20210720-75584", "type": "fabricant", "parent_uid": null, "version_application": "1.1.0", "creation_date": "2021-07-20T14:34:04.49Z", "titu": "REST1", "ref_cstb": "ref-18-taieb", "gamme": "SUPERGRES T_20", "serie": "WIND", "description": null, "usines": null } ], "version_schema": null }, { "name": "LOV F+", "parent": "QB", "produits": [{ "uid": "ITEM-20210720-33547", "type": "fabricant", "parent_uid": null, "version_application": "1.1.0", "creation_date": "2021-07-20T14:46:37.649Z", "titu": "REST1", "ref_cstb": "ref19-taieb", "gamme": "SUPERGRES T_20", "serie": "STOCKHOLM", "description": null, "usines": null }], "version_schema": null } ] } let obj1 = { "uid": "ITEM-20210715-20758", "type": "fabricant", "parent_uid": null, "version_application": "1.1.0", "creation_date": null, "titu": "REST1", "ref_cstb": "162367462", "gamme": "SUPERGRES", "serie": "PREMIERE", "description": "300x300 - 20 - Blue", "usines": null, "group": "QB - LOV D+", "parent": "QB" } function Remove(obj, parentObj) { let famille = parentObj.familles.findIndex((x) => x.name === obj.group.split(" - ").pop()); let produit = parentObj.familles[famille].produits.findIndex((x) => x.uid === obj.uid); parentObj.familles[famille].produits.splice(produit, 1); } Remove(obj1, Parent); console.log(Parent);

Answer 3

can't understamd your question properly but if you want to manually remove array then use

delete Parent.familles[0].produits[0]

delete keyword to delete and then path of array to delete.

Answer 4

You can search for the index of the particular element/object and then delete it using

delete Parent.familles[0].produits[0]

 const fruits = ["Banana", "Orange", "Apple", "Mango"]; console.log(fruits.indexOf("Apple"))
