Question

有人可以帮我这个JavaScript吗？我正在尝试克隆多个不同的输入。单击附加按钮时，我想独立克隆付款/付款。众议院负责我要克隆的选择和输入。我能够以我想要的方式克隆标准输入，但也希望使用它来克隆选择框。我也似乎可以使附加的按钮正确排列。我在JavaScript方面很糟糕，因此甚至不确定我是否会以正确的方式进行操作。任何帮助表示赞赏。

$(function() {
  $(document).on('click', '.btn-add', function(e) {
    e.preventDefault();

    var controlForm = $('.controls stuff:first'),
      currentEntry = $(this).parents('.entry:first'),
      newEntry = $(currentEntry.clone()).appendTo(controlForm);

    newEntry.find('input').val('');
    controlForm.find('.entry:not(:last) .btn-add')
      .removeClass('btn-add').addClass('btn-remove')
      .removeClass('btn-success').addClass('btn-danger')
      .html('<span class="glyphicon glyphicon-minus"></span>');
  }).on('click', '.btn-remove', function(e) {
    $(this).parents('.entry:first').remove();

    e.preventDefault();
    return false;
  });
});

.entry:not(:first-of-type) {
  margin-top: 10px;
}

.glyphicon {
  font-size: 12px;
}

Answer 1

我明白了，如果可以帮助其他人，这是我的代码。

$(function(){
        $(document).on('click', '.btn-add', function(e) {
            e.preventDefault();
            var parentRow = $(this).closest('.charge-row'),
                cloneRow = cloneChargeRow(parentRow);

            $('.charge-row:last').after(cloneRow);

        }).on('click', '.btn-remove', function(e) {
            $(this).closest('.charge-row').remove();

            e.preventDefault();
            return false;
        });

        function cloneChargeRow(parentRow) {
          // Clear existing add button
          $('.charge-row').find('.btn-add').removeClass('btn-add btn-success').addClass('btn-remove btn-danger');
          $('.charge-row').find('.btn').html('<span class="glyphicon glyphicon-minus"></span>')


          var newRow = parentRow.clone();

          newRow.find('.btn').addClass('btn-add btn-success').removeClass('btn-remove btn-danger');
          newRow.find('.btn').html('<span class="glyphicon glyphicon-plus"></span>');
          newRow.find('select :selected').removeAttr('selected');
          newRow.find('input').val('');

          return newRow;
        }
    });

这是html：

        <div class="container">
      <div class="col-md-10">

    <legend>House Charges - Richfield</legend>
        <div class="charge-row row">
          <!-- Dynamic House charges Divider-->
          <div class="col-md-3 col-md-offset-2 colspace">
            <div class="form-group">
              <select class="form-control" id="account_selector" name="house_account[]">
                <option>Select House Acct</option>
                <option>2</option>
                <option>3</option>
                <option>4</option>
                <option>5</option>
              </select>
            </div>                        
          </div>

          <div class="col-md-3 colspace">
            <div class="form-group">
              <div class="controls">
                <div class="entry input-group">
                  <input id="house_total" name="house_total[]" class="form-control" placeholder="Total $" type="text">
                  <span class="input-group-btn">
                    <button class="btn btn-success btn-add" type="button">
                      <span class="glyphicon glyphicon-plus"></span>
                    </button>
                  </span>
                </div>
              </div>
            </div>            
          </div>
        </div>
      </div>
