我已尝试运行 interact.js 拖放方法，如 example 中所示本身。我下载了 interact.js 和 interact.min.js 并将它们也包含在我的 html 文件中。但是这个功能好像没有实现。在这方面的任何建议将不胜感激。我在下面的上下文中为代码提供了 jsFiddle

/* The dragging code for '.draggable' from the demo above
* applies to this demo as well so it doesn't have to be repeated. */
// enable draggables to be dropped into this
interact('.dropzone').dropzone({
// only accept elements matching this CSS selector
accept: '#yes-drop',
// Require a 75% element overlap for a drop to be possible
overlap: 0.75,
// listen for drop related events:
ondropactivate: function(event) {
// add active dropzone feedback
event.target.classList.add('drop-active');
},
ondragenter: function(event) {
var draggableElement = event.relatedTarget,
dropzoneElement = event.target;
// feedback the possibility of a drop
dropzoneElement.classList.add('drop-target');
draggableElement.classList.add('can-drop');
draggableElement.textContent = 'Dragged in';
