動態更改文本框的值應該在單選按鈕單擊時更改？

我有3個文本框和與其相關的單選按鈕。第一個文本框的值從數據庫中檢索，所有計算都在數據庫值上完成。但是，如果我想手動更改第一個文本框的值， 2盒的值必須改變。而且我不想將這個手動輸入的值插入到數據庫中。你告訴我如何對手動插入的值進行計算。動態更改文本框的值應該在單選按鈕單擊時更改？

在此先感謝

是; ...你能告訴我們你要執行什麼樣的計算，並給出一個值和預期輸出/改變值的例子嗎？此外，您沒有任何「文本框」，您可能有三個'或''元素，或者這些元素的組合。 – <span class="text-secondary"> <small> <span></span> </small> </span> </p> </div> </div> </div> <div
