就我个人而言，我会把它全部扔掉然后重新开始，但如果要保留它，请将代码分解成小块并将它们放入方法中以便开始。读取所有意大利面条代码（特别是在加载事件中）是痛苦的。我想你***重新开始。

Personally I'd throw it all away and start again but if you are going to keep it, break the code down into little chunks and put them in methods for a start. It's painful reading all that spaghetti code ( especially in a load event ). I think you will be better off starting afresh.
