are all in the same interview
after add_favorite_btn click, I successfully changed the id property of add_favorite_btn to remove_favorite_btn
. At this time, I was pressing it, according to my idea, I could start remove_favorite_btn event
directly, but it turned out that he was still engaged in add_favorite_btn activities instead of remove_favorite_btn
. How could this happen?
