//设置关联数据 dragEl.addEventListener("dragstart", dragstartHandle);
//禁止默认事件,使其可拖放 dropEl.addEventListener("dragenter", preventDefault); dropEl.addEventListener("dragover", preventDefault);
//鼠标释放,在拖放目标上接受数据并处理 dropEl.addEventListener("drop", dropHandle); function dropHandle(event) { event.preventDefault(); var data = event.dataTransfer.getData("Text"); event.target.appendChild($("#" + data)); } function dragstartHandle(event) { event.dataTransfer.setData("Text", event.target.id); } function preventDefault(event) { console.log(event.type); event.preventDefault(); } function $(sel) { return document.querySelector(sel); } } </script> </body> </html>
