我努力改變文本的顏色，當它被點擊但沒有成功。 question有一個標籤，四個標籤options，一個標籤correct answer和一個標籤explanation。如何在使用jquery點擊文本時更改文本的顏色？
我試圖當任何option用戶點擊，那麼它應該與correct answer匹配，並更改選項，也就是文本的顏色時，答案是正確的文字顏色應該變成綠色，否則顏色應開啓變紅。
但是，當我點擊任何option它只會變成紅色。正確的option應該變成綠色，但它變成了紅色。我找不出原因。 看看我的代碼。告訴我我錯在哪裏以及解決方案是什麼。

可以請你把你的html代碼這裏。 –
你首先必須知道答案是否正確。然後改變顏色，這不應該很難。 – Ionut
只選擇.correctans不是全部，它顯然將它們全部設置爲紅色。 –
