我在我的應用程序中有兩個單選按鈕，其中一個是使用combobox的meterid，另一個是帶有文本框的consumername。現在的問題是，每當我選擇單選按鈕結果只是正確的，但我無法找到哪個單選按鈕，我已經選擇。如何找出使用jsp選擇了哪個單選按鈕

請幫我解決這個問題。
感謝您的回覆其實myproblem是我的應用程序2單選按鈕都有稱爲meterid和consumername。如果我選擇了consumername單選按鈕，結果正在顯示，但在得到結果後，單選按鈕正在進行休息，這意味着我無法看到我選擇了哪個單選按鈕。 –
爲了找到問題，我們需要知道是否正在執行JS函數searchOptions（1），如果它正在更新DOM，這是正常的，值被重置。 –
