我的CSS结构

.new-checkbox ul {
  padding: 0;

  list-style: none;
  margin-left: 30px;

.new-checkbox ul li {

.new-checkbox input[type="checkbox"][id]:checked ~ li::before {
  content: "\25bc";
}

.new-checkbox li ul {
  display: none;
}

.new-checkbox li.has-checked > ul {
  display: block;
}

和我的jquery

$(document).ready(function() {


  $('.new-checkbox input[type=checkbox]').on("change", function() {
    var checked = this.checked,
      $li = $(this).parent();
    $li.find('input[type=checkbox]').prop('checked', checked).parent().toggleClass('has-checked', checked);

    $li.parentsUntil('.new-checkbox', 'li').each(function() {
      var $checks = $(this).find('ul input[type=checkbox]');
      $(this).children('input[type=checkbox]').prop('checked', !$checks.filter(':not(:checked)').length);

      $(this).toggleClass('has-checked', $checks.is(':checked'));
    });

  });

/*
  $('.new-checkbox li input[type="checkbox"]').on("click",function(e) {
        $(this).parent("li").toggleClass("downCheck");
    });
*/

    if($('.new-checkbox li:has("> ul")')) {
       $('.new-checkbox li input[type="checkbox"]').on("click",function(e) {
          $(this).parent("li").toggleClass("downCheck");
      });
    }

});

and to see on codepen
