Adjusting the attributes of an item identified by a unique identifier

Question

Adjusting the attributes of an item identified by a unique identifier

I am working with an array of objects that looks like the following:

var data = [{
id: 1,
firstName: 'John',
secondName: 'Doe',
email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9ff5f0f7f1fbf0fadff2fef6f3b1fcf0f2">[email protected]</a>'}];

In my code, I have a function called update which prompts the user for an id and updates the data object with the same id using the values provided by the user. For example:

function update(firstName, lastName, email, id)

I am looking for a way to update the data array based on the id provided by the user and also return true if the specified id was found in the array.

Answer №1

Utilizing Destructuring Assignment to transfer an Object as arguments for a Function:

var users = [{
id : 1,
firstName : 'Jane',
lastName : 'Doe',
email : '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fd97929593999298bd909c94a1919292">[email protected]</a>'}];


function updateUser({firstName, lastName, email, id}){
  if(id == '1'){
    console.log(`update ${firstName}`)
  }
}

users.forEach(user => updateUser(user))

function modifyUserInfo(firstName, lastName, email, id) {
  var index = 0;
  while (index<dataCollection.length) { // looping through data array to find specified ID
    if (dataCollection[index].id == id) { // update values in the array when ID is found
      dataCollection[index].firstName = firstName;
      dataCollection[index].lastName = lastName;
      dataCollection[index].email = email;
      return true; // indicating that value was found and updated successfully
    }
    index++;
  }
  return false; // indicating that no matching value was found for the given ID
}

let information = [{
                   id : 1,
                   firstName : 'John',
                   secondName : 'Doe',
                   email : '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="aec4c1c6c0cac1cbeec3cfc7c280cdc1c3">[email protected]</a>'}];

function updateData(id, firstName, lastName, email){
    let user = information.find(item => item.id === id)

    if(!user){
        return false
    }

    user.firstName = firstName
    user.lastName = lastName
    user.email = email
 
    return true
}

console.log(updateData(1, 'Mike', 'Smith', '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0e6367656b4e636f6762206d6163">[email protected]</a>'))

console.log(information[0])

To ensure that the array only contains an object with the same Id, only one will be updated

function updateData(id, firstName, lastName, email){
    let user = information.find(item => item.id === id)

    if(!user){
        return false
    }

    user.firstName = firstName
    user.lastName = lastName
    user.email = email
 
    return true
}

console.log(updateData(1, 'Mike', 'Smith', '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0e6367656b4e636f6762206d6163">[email protected]</a>'))
