使用 HTML 中的 ondragover HTML 属性在 HTML 中拖动元素时执行脚本。
您可以尝试运行以下代码来实现ondragover 属性 -
<!DOCTYPE HTML> <html> <head> <style> .drag { float : left; width : 100px; height : 35px; border : 2px dashed #876587; margin : 15px; padding: 10px; } </style> </head> <body> <div class = "drag" ondrop = "drop(event)" ondragover = "dropNow(event)"> <p ondragstart = "dragStart(event)" ondrag = "draggingNow(event)" draggable = "true" id="dragtarget">Drag!</p> </div> <div class = "drag" ondrop = "drop(event)" ondragover = "dropNow(event)"></div> <div id = "box"></div> <p>Drag the left box to the right or drag the right box to the left.</p> <script> function dragStart(event) { event.dataTransfer.setData("Text", event.target.id); } function draggingNow(event) { document.getElementById("box").innerHTML = "Dragged successfully!"; } function dropNow(event) { event.preventDefault(); } function drop(event) { event.preventDefault(); var data = event.dataTransfer.getData("Text"); event.target.appendChild(document.getElementById(data)); document.getElementById("box").innerHTML = "The element dropped successfully!"; } </script> </body> </html>
