jquery - 如何仅 append 到每个 div 一次

Question

我有几个问题，用户将单击"is"或“否”按钮，并希望将其单击的值 append 到一个显示他们选择的内容的空类中。

每次我单击"is"或“否”时，该值都会 append 到每个问题中，以便在底部显示这些值，即“是、否、否、是”。我希望只显示该特定问题的值。

到目前为止我所拥有的 -

$(function() {
var answer = $(".answer");
answer.each(function(index) {
$(this).on("click", function(){
  var userAnswer = $(this).attr("data-id");
  var displayAnswer = $(".display-answer");
  displayAnswer.each(function() {
      $(this).append(userAnswer);
    });
   });
  });
});

HTML

<div class="question-wrap">
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Maiores, ea maxime velit hic tenetur, animi. Similique dolorem modi quos eius in, unde, sapiente, non ipsa aliquam accusamus quis facilis enim.</p>
        <div class="answer-buttons">
            <div class="answer yes"><p>Yes</p></div>
            <div class="answer no"><p>No</p></div>
        </div>
        <div class="display-answer"></div>
    </div>

Answer 1

这是获得您描述的结果的方法

    $(function(){
    	$(".answer").click(function(){ /*You can register the click handler easily in one step*/
      	var userAnswer = $(this).attr("data-id");
        $(this).parent().siblings(".display-answer").append(userAnswer); /*First, find the parent, then the "display-answer" siblings*/
      });
    
    });

p{
  font-family:sans-serif;
}

.answer{
  border:1px solid black;
  text-align:center;
  flex-grow:100;
  width:100px;
  display:inline-block;
}
