提前，道歉的代碼量。我想提出一個完整的圖片。爲什麼單選按鈕消失與JQuery驗證？
我的問題：當表單驗證（使用Jquery Validate）時，如果用戶在發送前沒有選擇單選按鈕，單選按鈕將消失。我怎樣才能解決這個問題？
UUUHMM：當我從單選按鈕中刪除「必需」時，單選按鈕不會消失。你會認爲「問題解決了」，但是我確實需要在沒有使用單選按鈕時顯示一條消息，並且這不會發生。
檢查Windows計算機後，我看到沒有任何消息顯示在Windows計算機上。什麼？？？我究竟做錯了什麼！？在Mac上顯示消息。

您是否嘗試過使用您的代碼段？它在我的瀏覽器中提出錯誤「myFunction未定義」 – blackmiaool
@blackmiaool，我做了編輯以解決「myFunction未定義」問題。但是這不能解決我的問題。當使用發送按鈕而沒有首先選擇單選按鈕時，單選按鈕仍然消失。 – Eddy
如何重現你的問題呢？我試圖「發送」按鈕，但沒有任何事情發生。你能否提供更簡單的演示並描述如何重現它？ – blackmiaool
