【问题描述】:
这两个图像都旨在被拖入leftbox div。当您拖动橙色图像上方列出的蓝色图像时。它成功落入leftbox。当您将橙色图像拖动到放置目标时,蓝色图像会在放置后替换它。这是因为它列在橙色图像的上方。我通过交换代码顺序对此进行了测试。将橙色图像放在首位。橙色图像是当时唯一的接收者。任何帮助表示赞赏。
function allowdrag(e) {
e.preventDefault();
}
function Drop(e) {
e.preventDefault();
var texts = e.dataTransfer.getData('image/png')
var data = document.getElementById(texts);
e.target.appendChild(data)
}
function drog(e) {
e.dataTransfer.setData('image/png', e.target.id)
