javascript - グループ内のラジオボタンの値を取得するホット

Question

2 つの異なるグループからラジオ ボタンの値を取得する方法 (DIV: ステップ 1 とステップ 2)?? 実際には5つ持っていますが、同じ話になります。

初期化中

        var a1Id;
        var a2Id; 
        var a3Id;
        var a4Id; 
        var a5Id;
        var a6Id; 

a1Id = questionaireResult.questions[0].answers[0].id; (value of id = 1)
            document.getElementById('antwort1fuerFrage1').value = a1Id;

 a2Id = questionaireResult.questions[0].answers[1].id; (value of id = 2)
                document.getElementById('antwort2fuerFrage1').value = a2Id;

and so on for 3,4,5, and 6...

JQUERY hier 選択したラジオボタンの値を読みたいです。グループごとにやってる

var selected = $("#step-1 input[type='radio']:checked");
                if (selected.length > 0) {
                    var answerIDQ1 = $('input[class=group1]:checked').val();
                }

                var selected = $("#step-2 input[type='radio']:checked");
                if (selected.length > 0) {
                    var answerIDQ2 = $('input[class=group2]:checked').val();
                }

HTML
