A Javascript question (Objects in a loop).

Question

Hi guys!

Just wanna ask for help on my code i got stuck on how to implement a Object inside a For Loop.

So I have this to do's:

create Object containing bio of a user.
Asked Name, Aged, Sex.

So far this is my code:

var userQuestions = [
    "Name",
    "Age",
    "Sex"
];

var userDetails = {
    user : '',
    age : 0,
    sex : ''
}

console.log(userDetails);


    for (var i = 0; i < userQuestions.length; i+=1){
        var question = userQuestions[i];
        var answer = prompt(question);

        if( answer ) {
            //HOW TO ADD THE ANSWERS TO MY OBJECTS KEYS userDetails.
        }

    }

As you can see I can figure out how to add the Users Answer back to the Object named usersDetails. I was thinking just to update the userDetails.name = 'User Answer'. But I can think on how to use the objects index if its possible.

I appreciate for your help!

Thanks,

Owa

Hi Owa,

This is pretty simple to implement, with one small change! Did you notice that the questions in your array are very similar to the object properties that you want to use? The only exceptions are that you have a question 'Name' and the corresponding property is 'user', and of course your object properties are lower case.

If you create a third variable, key, which you set to be equal to the lower-case version of your question, then you can then use this to access the corresponding property in your object:

for (var i = 0; i < userQuestions.length; i+=1){
    var question = userQuestions[i];
    var answer = prompt(question);
    var key = question.toLowerCase();

    if( answer ) {
        userDetails[key] = answer;
    }
}

I hope this helps, Chris
