獲取單選按鈕的值設置

Question

我設置了響應由單選按鈕標記處理選擇題調查問卷A，B，C和D.

我想找出答案，每個通過獲取表單ID和單擊的按鈕值來提出問題，例如，使用第一組單選按鈕的響應可能是1B和第二，2D等等（表單ID腳本已經啓動並運行）。

我需要這與多組單選按鈕

這裏的頁面上工作是HTML：

<form class="toeic_pages" id="1"> 
     <label class="item1"> 
     <input type="radio" value="A" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
     <label class="item2"> 
     <input type="radio" value="B" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
     <label class="item3"> 
     <input type="radio" value="C" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
     <label class="item4"> 
     <input type="radio" value="D" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
    </form> 
    ...                 
    <form class="toeic_pages" id="2"> 
     <label class="item1"> 
     <input type="radio" value="A" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
     <label class="item2"> 
     <input type="radio" value="B" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
     <label class="item3"> 
     <input type="radio" value="C" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
     <label class="item4"> 
     <input type="radio" value="D" name="toeic"/> 
     <div class="radio-image"></div> 
     </label> 
    </form> 

不過，雖然我已經能夠用得到檢查單選按鈕值這個：

jQuery('input[name=toeic]').change(function(){ 
     var invar = jQuery('input[name=toeic]:checked').val(); 
     alert(invar); 
    }); 

該腳本只在點擊的第一行按鈕內有效。

爲了說明，如果在要訪問的第一行按鈕中點擊按鈕B，則顯示B（正確）。

但是，如果在另一行中，點擊了按鈕C，則B顯示（不正確）..並且B繼續顯示以用於所有後續的按鈕點擊。我已經檢查了這個SO網頁，但我一直沒有找到解決方案 - 這個問題似乎是多套單選按鈕。

任何幫助將非常讚賞

你可以做這樣的事情：

$(document).ready(function() { 
 
    $("#finish").click(function() { 
 
    var answersList = []; 
 
    //Loop over all questoins 
 
    $(".toeic_pages").each(function() { 
 

 
     var questionId = $(this).attr("id"); 
 
     var answer = $("input[name='toeic']:checked", $(this)).val(); 
 

 
     //if Answer isnt provided do not update the answersList 
 
     if (answer !== undefined) { 
 
     answersList.push({ 
 
      question: questionId, 
 
      answer: answer 
 
     }); 
 
     } 
 
    }); 
 
    console.log(answersList); 
 
    }); 
 
});

<form class="toeic_pages" id="1"> 
 
    <label class="item1"> 
 
    <input type="radio" value="A" name="toeic" /> 
 
    <div class="radio-image"></div> 
 
    </label> 
 
    <label class="item2"> 
 
    <input type="radio" value="B" name="toeic" /> 
 
    <div class="radio-image"></div> 
 
    </label> 
 
    <label class="item3"> 
 
    <input type="radio" value="C" name="toeic" /> 
 
    <div class="radio-image"></div> 
 
    </label> 
 
    <label class="item4"> 
 
    <input type="radio" value="D" name="toeic" /> 
 
    <div class="radio-image"></div> 
 
    </label> 
 
</form> 
 
... 
 
<form class="toeic_pages" id="2"> 
 
    <label class="item1"> 
 
    <input type="radio" value="A" name="toeic" /> 
 
    <div class="radio-image"></div>

    <label class="item4"> 
 
    <input type="radio" value="D" name="toeic" /> 
 
    <div class="radio-image"></div> 
 
    </label> 
 
</form> 
 

 
<button id="finish">Get Answers</button>

我認爲這正是你需要的。

$('#1 input').on('change', function() { 
 
     alert($('#1').attr('id')+$('input[name=radioName]:checked', '#1').val()); 
 
    }); 
 
    $('#2 input').on('change', function() { 
 
     alert($('#2').attr('id')+$('input[name=radioName]:checked', '#2').val()); 
 
    }); 
 
    $('#3 input').on('change', function() { 
 
     alert($('#3').attr('id')+$('input[name=radioName]:checked', '#3').val()); 
 
    }); 
 
    $('#4 input').on('change', function() { 
 
     alert($('#4').attr('id')+$('input[name=radioName]:checked', '#4').val()); 
 
    });
