JavaScript - 添加和删除 div onclick 子 href

Question

在我的表单中，我有一个名为 Add Record 的 href，单击它会向表单添加新的 html 元素行。添加的 html 元素行具有 remove 和 add href。单击该行末尾的 remove 后，该特定行将被删除...但是，当我单击子元素上的 add 时，会出现一个新行没有被创建。

$(document).ready(function(e) {

  var html = '<div><label>Category:</label><select id="childcategory"><option value="0" selected>Select Category</option><option value="CatA">Category A</option><option value="CatB">Category B</option></select><a href="#" id="remove">Remove</a><a href="#" id="childAdd">AddRecord</a></div>';
  var maxRows = 20;
  var x = 1;
  //Add rows
  $("#add").click(function(e) {
    if (x <= maxRows) {
      $("#container").append(html);
      x++;
    }
  })

  /*//Add rows
  $("#container").on('click', '#childAdd', function(e){
      $(this).parent('div').add();
      x++;
      })
  })*/

  //Remove rows
  $("#container").on('click', '#remove', function(e) {
    $(this).parent('div').remove();
    x--;
  })
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
  <div id="container" class="container-fluid">
    <div class="row">
      <div class="col-sm-12">
        <div class="main-content">
          <div class="block">
            <label>Category:</label>
            <select id="category" name="category[]" required>
                          <option value="0" selected>Select Category</option>   
                          <option value="ToiletSoap">Toilet Soap</option>
                          <option value="ToothPaste">ToothPaste</option>
                        </select>
            <a href="#" id="add">Add record</a>
          </div>
        </div>
      </div>
    </div>
  </div>
</form>

您可以使用相同的函数来添加记录，我希望这是您期望的输出，如果不是请评论，我会更新

$(document).ready(function(e) {

  var html = '<div><label>Category:</label><select id="childcategory"><option value="0" selected>Select Category</option><option value="CatA">Category A</option><option value="CatB">Category B</option></select><a href="#" id="remove">Remove</a><a href="#" id="childAdd">AddRecord</a></div>';
  var maxRows = 20;
  var x = 1;
  //Add rows
  $("form").on('click','#add, #childAdd', function(e) {
    if (x <= maxRows) {
      $("#container").append(html);
      x++;
    }
  })


  //Remove rows
  $("#container").on('click', '#remove', function(e) {
    $(this).parent('div').remove();
    x--;
  })
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
  <div id="container" class="container-fluid">
    <div class="row">
      <div class="col-sm-12">
        <div class="main-content">
          <div class="block">
            <label>Category:</label>
            <select id="category" name="category[]" required>
                          <option value="0" selected>Select Category</option>   
                          <option value="ToiletSoap">Toilet Soap</option>
                          <option value="ToothPaste">ToothPaste</option>
                        </select>
            <a href="#" id="add">Add record</a>
          </div>
        </div>
      </div>
    </div>
  </div>
</form>
