从不同的单选按钮组获取单选按钮标签并附加到分区

Question

有3个单选按钮组供用户选择。只要用户选中要显示的单选按钮标签，就会获得分区'#targetOption'。在我的代码下面，它能够获得第一个选中的单选按钮。

例如，如果用户单击第一个单选按钮组，＃targetOption将显示A.然后，如果用户单击第二个单选按钮组，＃targetOption将显示A B.

<div id="options">
    <div class="form-group required"> 
        <div class="radio"> 
            <label> <input type="radio" value="a">
            A   
            </label> 
        </div>
        <div class="radio"> 
            <label> <input type="radio" value="b">
            B   
            </label> 
        </div>
        <div class="radio"> 
            <label> <input type="radio" value="c">
            C   
            </label> 
        </div>
    </div>

    <div class="form-group required"> 
        <div class="radio">

        <div class="radio">

            F   
            </label> 
        </div>
    </div>

    <div class="form-group required"> 
        <div class="radio"> 
            <label> <input type="radio" value="g">
            G

        <div class="radio"> 
            <label> <input type="radio" value="h">

        <div class="radio">

            I   
            </label> 
        </div>
    </div>
  </div>  
    <div id="targetID"></div>

        $('#options').click(function() {
                        $('#targetID').html('');

                        $("input[type='radio']:checked").each(function() {
                          var optiontext = $(this).parent().text();
                          console.log(optiontext);
                         $('#targetID').html(optiontext);
                        });


                      });
