運行此代碼時，進行修正顯示在標籤上選擇的第一個按鈕的名稱中的「功能radioButtonClick」，但是當你選擇別的東西后，它不更新，並且按鈕標籤出來交換。

所以基本上，會發生什麼情況是：

點擊單選按鈕，1 - >顯示 「1選擇」 然後， 點擊單選按鈕2 - >什麼也沒有發生。 然後再次點擊 單選按鈕，1 - >顯示「2選擇」 最後，再次 點擊單選按鈕2 - >顯示「1選擇」

我該如何解決這個問題？

預先感謝您。

您的代碼沒有什麼意義，每次單選按鈕更改時都會創建一個新標籤，並且您在每次單擊時註冊一個新的NSD_OnChange事件處理函數，並且此處理函數會嘗試在該函數的頂部創建另一個頁面舊的，這是完全不受支持的行爲！

有很多方法來編寫，這裏有3個例子：
