How can I remove all objects which are having `areWeCreatingNewUser` property

June 5, 2023

I have the following object

const obj = {
    "title": "sample",
    "status": 0,
    "creationDate": null,
    "userGroup": "",
    "signatureDelay": "2023-06-05T11:07:18.786Z",
    "listSign": [],
    "priority": false,
    "nature": null,
    "qesData": {
        "signatories": [
            {
                "displayName": "Some user",
                "email": "someuser@hotmail.com",
                "firstname": "User first name",
                "id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04",
                "lastname": "User last name",
                "locale": "en",
                "signatoryAttributes": []
            },
            {
                "email": "test@hotmail.com",
                "displayName": "",
                "areWeCreatingNewUser": true
            },
            {
                "email": "test1@hotmail.com",
                "displayName": "",
                "areWeCreatingNewUser": true
            }
        ]
    },
    "fileName": "sample.pdf",
}

I need to loop through the qesData => signatories array and remove all of the objects there which are having areWeCreatingNewUser property set to true.

So I tried

for(var i = 0;i < obj.qesData.signatories.length;i++) {
            if(obj.qesData.signatories[i].areWeCreatingNewUser) {
                obj.qesData.signatories.splice(i,1);
            }
        }

the problem here is that the first time when it founds the user with email test@hotmail.com it remove it with splice at index 1 and after that the obj.qesData.signatories is modified and on next iteration it does not remove the user with email test1@hotmail.com

How can I solve this issue ?

Also I forgot to mention that I need to use old javascript code,filter is not an option

>Solution :

You can use Array.filter() to do it

const obj = {
    "title": "sample",
    "status": 0,
    "creationDate": null,
    "userGroup": "",
    "signatureDelay": "2023-06-05T11:07:18.786Z",
    "listSign": [],
    "priority": false,
    "nature": null,
    "qesData": {
        "signatories": [
            {
                "displayName": "Some user",
                "email": "someuser@hotmail.com",
                "firstname": "User first name",
                "id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04",
                "lastname": "User last name",
                "locale": "en",
                "signatoryAttributes": []
            },
            {
                "email": "test@hotmail.com",
                "displayName": "",
                "areWeCreatingNewUser": true
            },
            {
                "email": "test1@hotmail.com",
                "displayName": "",
                "areWeCreatingNewUser": true
            }
        ]
    },
    "fileName": "sample.pdf",
}

obj.qesData.signatories = obj.qesData.signatories.filter(d => !d.areWeCreatingNewUser)
console.log(obj)

Update: for ES5 style,below is a reference for you

const obj = {
    "title": "sample",
    "status": 0,
    "creationDate": null,
    "userGroup": "",
    "signatureDelay": "2023-06-05T11:07:18.786Z",
    "listSign": [],
    "priority": false,
    "nature": null,
    "qesData": {
        "signatories": [
            {
                "displayName": "Some user",
                "email": "someuser@hotmail.com",
                "firstname": "User first name",
                "id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04",
                "lastname": "User last name",
                "locale": "en",
                "signatoryAttributes": []
            },
            {
                "email": "test@hotmail.com",
                "displayName": "",
                "areWeCreatingNewUser": true
            },
            {
                "email": "test1@hotmail.com",
                "displayName": "",
                "areWeCreatingNewUser": true
            }
        ]
    },
    "fileName": "sample.pdf",
}

let data = []
for(d of obj.qesData.signatories){
   if(!d.areWeCreatingNewUser){
     data.push(d)
   }
}

obj.qesData.signatories = data
console.log(obj)
