在此先感谢，我正在尝试将粘性图像一个接一个地添加，如下图所示，但我得到的结果是一个在另一个下面。最新添加的便签应该在最上面，所有其他的便签都在最新的后面。任何帮助将不胜感激。

最佳答案

定位粘性并将其放入容器中。然后根据 .sticky 计数分配 left 值。检查下面的片段。

$('#addProblem').click(function() {
  $('.sticky').after('<div class="sticky"><textarea placeholder="Type the problem here..."></textarea><br></div>');
  var stickyCount = $('.sticky').length - 1;
  $('.sticky').each(function() {
    $(this).css('left', stickyCount * 100);
    stickyCount--;
  });
});
