这是CSS和HTNL代码。

所以我需要修改这些代码才能拥有克隆对象。

试试此代码示例

interact('.draggable').draggable({
    inertia: true,
    restrict: {
      restriction: "#visualizer-panel",
      endOnly: true,
      elementRect: { top: 0, left: 0, bottom: 1, right: 1 }
    },
    onmove: function (event) {
      var target = event.target;   
      var x = (parseFloat(target.getAttribute('data-x')) || 0) + event.dx;
      var y = (parseFloat(target.getAttribute('data-y')) || 0) + event.dy;

      target.style.webkitTransform =
      target.style.transform = 'translate(' + x + 'px, ' + y + 'px)';

      target.setAttribute('data-x', x);
      target.setAttribute('data-y', y);
    },
    onend: function(event) {
        console.log(event);
    }
}).on('move', function (event) {
var interaction = event.interaction;
if (interaction.pointerIsDown && !interaction.interacting() && event.currentTarget.getAttribute('clonable') != 'false') {
  var original = event.currentTarget;
  var clone = event.currentTarget.cloneNode(true);
  var x = clone.offsetLeft;
  var y = clone.offsetTop;
  clone.setAttribute('clonable','false');
  clone.style.position = "absolute";
  clone.style.left = original.offsetLeft+"px";
  clone.style.top = original.offsetTop+"px";
  original.parentElement.appendChild(clone);
  interaction.start({ name: 'drag' },event.interactable,clone);
}
});

如何使用interact.js拖动，删除和克隆对象

这是CSS和HTNL代码。
