参考链接:https://segmentfault.com/a/1190000013606983
例子:
<!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>菜鸟教程(runoob.com)</title> <style type="text/css"> #div1 {width:350px;height:70px;padding:10px;border:1px solid #aaaaaa;} </style> <script> function allowDrop(ev) { ev.preventDefault(); } function drag(ev) { ev.dataTransfer.setData("Text",ev.target.id); } function drop(ev) { ev.preventDefault(); var data=ev.dataTransfer.getData("Text"); ev.target.appendChild(document.getElementById(data)); } </script> </head> <body> <p>拖动 RUNOOB.COM 图片到矩形框中:</p> <div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <br> <img id="drag1" src="https://www.runoob.com/images/logo.png" draggable="true" ondragstart="drag(event)" width="336" height="69"> </body> </html>
注意:
drop 是拖放结束的目标区域,要先把dragover的默认事件禁止才能出发drop事件
