Javascript Interactjs - 在放置区中删除 div 项
Javascript Interactjs - Delete div item on drop in dropzone
使用 interactjs 我正在尝试删除一个项目，当它被放入作为垃圾箱的放置区时。这里棘手的部分是放置区必须在 position:fixed 中并且最初可拖动的项目在 position:relative 中。我认为这会导致 dropzone 无法检测到当可拖动对象处于不同位置时什么时候被丢弃。我试图通过在拖动项目时将 position:absolute 更改为可拖动来解决此问题（on.dragmove），但不可避免地，可拖动与放置区重叠。我该怎么做？
