[英]Javascript - Uncaught SyntaxError: Unexpected token 'else'
這是我第一次學習編程 Javascript 並且一直在研究這個程序，在牆上喝 99 杯飲料直到它達到零。我從早上 12 點開始學習這個程序......現在是凌晨 3 點，我瘋了，無法看到我的錯誤。
我在哪里 go 錯了？ 我以后如何防止這種情況發生？
這是我在制作 JS 程序時的第一次嘗試，所以請不要太討厭我，我剛剛打開一本書，從晚上 11 點 30 分開始直到現在凌晨 3 點問。
謝謝男生或女生！

你在 vars 中做了換行符。
你寫的是drink而不是drinks
通過<script type="text/javascript">更改<script> >
謝謝你！ 事實證明我的代碼不起作用，因為我沒有在 IF/ELSE 語句中將s添加到“drink”。 我有一個變量拼寫錯誤，導致代碼無法打印。
