javascript - 如何使用jquery-ui使可拖动div可调整大小

我创建了一些小部件，这些小部件应该在屏幕上的任意位置为draggable，并由用户为resizable。我设法使它们成为draggable，但不能使它们成为resizable。这是小提琴：

https://jsfiddle.net/vaxobasilidze/reL880g8/

我究竟做错了什么？我也有其他元素，可以通过相同的方式使它们可拖动和调整大小，但是由于未知的原因，这仅在此小部件上不起作用。



function foo(){
  $('.channel').each(function() {
    $(this).draggable({
      containment: $('.screens'),
      stack: '.channel',
      drop: function (event, ui) {

      },
      drag: function(){
        var draggedItemId = $(this).attr('id');
      },
      stop: function(){
        var draggedItemId = $(this).attr('id');
      }
    }).resizable();
  });
}

function makeDraggable(){
  var height = $('.channels').height();
  $('.ram').draggable({
    stack: '.ram',
  }).resizable();
}

makeDraggable();
foo();

另一个更新是先添加resizable，然后像draggable一样调用$(this).resizable().draggable()我对代码进行了此类更改。您现在可以使用相同的代码。
