Question

运行下面的代码段，将至少两个项目拖到中心，按＆＃34;创建＆＃34;按钮并尝试连接端点以查看问题。

当我尝试连接来自不同div的端点时，它们实际连接，但问题是，连接路径显示错误。它始终连接源端点所在的同一div中的端点。尽管如此，如果你将鼠标悬停在我真正想要连接的点上，它会显示连接已完成，甚至拖动也能正常工作。亲自尝试一下，获得完整的体验。

$(document).ready(function() {
  $('#deviceName li').draggable({
    helper: 'clone',
    revert: 'invalid'
  });
  $('#interface li').draggable({
    helper: 'clone',
    revert: 'invalid'
  });
  $('#display li').draggable({
    helper: 'clone',
    revert: 'invalid'
  });
  $('#output li').draggable({
    helper: 'clone',
    revert: 'invalid'
  });
function foo(){
  $('.foo').each(function() {
    $(this).draggable({
      containment: $(this).parent(),
      stack: '.foo'
    });
  });
}
  $('#mainDiv').droppable({
    drop: function(event, ui) {
      if (!ui.draggable.hasClass('foo')) {
        var title = ui.draggable.text().trim();
        var item = $('<div class="foo">').append('<table class="elementTable"><tr><th class="thClass">' + title + '</th></tr><tr class="tableBody"><td class="tableConn">Link 1</td></tr><tr><td class="tableConn">Link 2</td></tr></table>');
        item.draggable();
        $(this).append(item);
        foo();
      }
    }
  });
});
