adding multiple values to an array or object in javascript

Question

i like to have array or object like:

[0]
   text:"first"
   id: 1
[1]
   text:"second"
   id: 2
[2]
   text:"third"
   id: 3

getting myself:

1: first
2: 1
3: second
4: 2
5: third
6: 3

here is my javascript with implementation for the array at the moment:

 var numberOfQuestions = questionaireResult.numberOfQuestions;
                var i;
                var j;
                var result = [];

                for (i = 0; i < numberOfQuestions; i++) {
                    debugger;
                    var question = questionaireResult.questions[i].text;
                    var questionID = questionaireResult.questions[i].id;


                    for (j = 0; j < questionaireResult.questions[i].answers.length; j++) {

                        var text = questionaireResult.questions[i].answers[j].text;
                        var id = questionaireResult.questions[i].answers[j].id;
                        result.push(text, id);
                    }
}

Push an object containing your data to the array instead:

result.push({text: text, id: id});

@RagimsRagimovs: In the next version of JavaScript (ECMAScript6), it'll be even more concise: result.push({text, id}); (that will be functionally identical to the above; basically it just figures out the name of the property from the name of the variable). But we don't have ES6 yet. :-)

Assuming that you want to store all answers into a single array, you could use concat to get the expected result and reduce the amount of code at the same time :

var questions = questionaireResult.questions,
    result = [],
    l = questions.length,
    i = 0;

for (; i < l; i++) {
    result = result.concat(
        questions[i].answers
    );
}

Here is how concat works (mdn doc) :

var a = [1, 2, 3],
    b = [4, 5, 6];
a.concat(b); // [1, 2, 3, 4, 5, 6]
