代码适用于JSFiddle，但在本地保存时不起作用 [英] Code works on JSFiddle but when saved locally doesn't work
问题描述
我正尝试从用户那里接收输入并将其显示为列表。幸好有人已经做到了，并在JSFiddle上找到了它。代码工作正常，但当我在本地移动时，它不起作用。当我输入文字时，没有任何反应。我在这里遇到类似的问题，但仍然无法正常工作。
I am trying to take in input from the user and display it as a list. Thankfully someone has already done it and found it on JSFiddle. The codes works fine there but when I move it locally, it is not working. When I enter the text, nothing happens. I went through similar issues here but still not working.
如果您发现错误，请指教。谢谢。
Please advice if you spot the mistake. Thank you.

推荐答案
将它放在 $（document）.ready（）{} 或将它移动到 body 的结尾处让它再次运作。
Since your jquery code comes before your html, i think putting it in a $(document).ready() {} or moving it to the end of the body will make it work again.
