推荐答案

不，这根本不是事件冒泡的代码.

建议您先阅读，然后尝试，然后在遇到问题时发布特定问题. :thumbsup:

No, this is not at all the code of event bubbling.

Would suggest you to read first, then try and then post specific issue if faced. :thumbsup:

没有问题，并从标题中删除了((是对的))".我们无法告诉您您的代码是否正确"，因为我们没有(也不想要)您的所有代码.如果可以编译，请在调试器下运行它.如果不正确，您很快就会知道.

Not a question, and removed "(Is it right)" from title. We can''t tell you if your code is "right", because we don''t have (nor do we want) all of your code. If it compiles, run it under the debugger. If it''s not right, you''ll know in short order.
