您需要在数据路径之前设置点。Docker-comose需要知道数据与docker-compose文件位于同一路径

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<section class="content container-fluid" id="quiz">
  <button class="btn btn-primary" id="next">Next</button>
  <button class="btn btn-info" id="prev">Prev</button>
  <button class="btn btn-default" id="start">Start Over</button> //checkboxes inputs for the final results
  <ul id="result-input" class="hide-input">
    <li><input type="checkbox" name="answer" value="0">1</li>
    <li><input type="checkbox" name="answer" value="1">2</li>
    <li><input type="checkbox" name="answer" value="2">3</li>
    <li><input type="checkbox" name="answer" value="3">4</li>
    <li><input type="checkbox" name="answer" value="4">5</li>
    <li><input type="checkbox" name="answer" value="5">6</li>
  </ul>
</section>

错误是错误的卷的映射：

my_couchdb_data:/opt/couchdb/data

应该是

    // here we add event handler for newly created checkboxes.
    nextQuestion.find("input[type='checkbox']").on('change',function () {

      if ($(this).is(":checked")) {

        //add checkbox background when is checked
        $(this).addClass("input-before");

        //uncheck the checkbox if another checkbox is checked
        $('#next').prop("disabled",false);
        $('input.cb').not(this).prop('checked',false,function(){
          //remove the background ...this is not working
          $(this).removeClass("input-before");
        })

      } else {
        $('#next').prop("disabled",true);
        $(this).removeClass("input-before");
      }
    });
