 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);
                    }
}

please help to get a structured array or object

Answer 1

将包含您的数据的对象推入数组：

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

Answer 2

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]
