Question

在使用拖放字段或元素到容器时，是否有办法在页面上生成多个放置区域？例如，如果我有一个容器，当一个字段放在它上面时，它将动态生成顶部，左侧，右侧和底部放置区域。所以我可以选择格式化行和列的字段。像这样Demo page。我想将这些字段样式/设置存储到数据库中。

任何人都会遇到这样的事情？

当然，只需使用一个类作为dropzone选择器（基于https://jqueryui.com/droppable/的代码）

  $(function() {
    $("#draggable").draggable();
    $(".droppable").droppable({
      drop: function( event, ui ) {
        // detect which dropzone the object was dropped into
        var index =  $(".droppable").index(this);
        $( this )
          .addClass( "ui-state-highlight" )
            .find( "p" )
            .html( "Dropped in box with index: " + index);
      }
    });
  });
  </script>
</head>
<body>
<div id="draggable" class="ui-widget-content">
  <p>Drag me to my target</p>
</div>

<div class="droppable" class="ui-widget-header">
  <p>Drop here</p>
</div>
<div class="droppable" class="ui-widget-header">
  <p>no, Drop here</p>
</div>
<div class="droppable" class="ui-widget-header">
  <p>rather, Drop here</p>
</div>
<div class="droppable" class="ui-widget-header">
  <p>you should really Drop here</p>
</div>
</body>
