最初在数字数组中曾经是数字，但工作正常，但是当我将数字更改为图片时，我可以拖动它们，但不能将其放到正确的位置，例如..它们是可拖动但不能拖放的！我没有触摸代码，只是更改了数组和循环以显示图片，任何人都不知道该怎么办，请吗?
originally in the numbers array used to be numbers and it was working fine but then when i changed the numbers into pictures, i'm able to drag them but i'm not able to drop in the right place, like .. they are dragable but not dropable ! i didn't touch the code i only changed the array and the loop to show the pictures, anyone have any idea what to do, please ?
