Answer 1

This code should work. 此代码应该起作用。 These are easy to spot problems, just open up your javascript console (F12) and you'll see you have an extra ) on line 8, and a missing one line 10. There was also a typo on degCent . 这些很容易发现问题，只需打开JavaScript控制台 （F12） ，您就会在第8行看到一个额外的) ，而在第10行缺少了一个degCent上还有一个错字。
