js调用浏览器的打印功能后，当用户点击确定打印或取消打印时我怎么知道？

当用户点击确定打印或取消打印后，我需要将css样式换回原来的样式，卡在不知道JS如何描述点击确定或取消了，求大神指点一二！

Have you solved it? I have encountered this problem recently and I want to know how I can know whether he clicked the "Print" or "Cancel" button

不需要js做任何事情，使用专门给打印机写的css样式就可以了。使用媒体查询@media print来针对打印机写样式，当你点击打印时，这个css样式会起作用，当你取消打印时，就会恢复成原来的样式
