<!DOCTYPE HTML> <html> <head> <style type = "text/css"> #boxA, #boxB { float:left;padding:10px;margin:10px; -moz-user-select:none; } #boxA { background-color: #6633FF; width:75px; height:75px; } #boxB { background-color: #FF6699; width:150px; height:150px; } </style> <script type = "text/javascript"> function dragStart(ev) { ev.dataTransfer.effectAllowed = 'move'; ev.dataTransfer.setData("Text", ev.target.getAttribute('id')); ev.dataTransfer.setDragImage(ev.target,0,0); return true; } </script> </head> <body> <center> <h2>Drag and drop HTML5 demo</h2> <div>Try to drag the purple box around.</div> <div id = "boxA" draggable = "true" ondragstart = "return dragStart(ev)"> <p>Drag Me</p> </div> <div id = "boxB">Dustbin</div> </center> </body> </html>
