最初在数字数组中曾经是数字并且它工作正常但是当我将数字更改为图片时，我能够拖动它们但是我不能放在正确的位置，比如...它们是可拖动但不可丢弃的！我没有触摸代码我只更改了数组和循环来显示图片，任何人都知道该怎么做，拜托？

这是style.css文件

代码最初是针对数组中的10个元素请帮助

好吧，我找到了答案，如果有人需要这个代码，你只需要编辑

function handleCardDrop( event, ui ) {
      var slotNumber = $(this).data( 'string' );
      var cardNumber = ui.draggable.data( 'string' );

这样它会检测到字符串:) 祝你有愉快的一天
