I have been busy for 3 days, I finally solved the bug, in fact, it is not difficult, especially Michael gives me my thinking, but the main thing is that the code gives it a lot, so it is very chaotic, some statements are not very good. Match, such as the} in JavaScript's annotation statement,} in the true execution statement, {match, make real statements very well. Finally, I have deleted them, and I can reach it. There are still 2 days left, there are 2 bugs, the head is big ..........
