打算做一個在線的純前端的問卷調查，一共有十個題目，選擇A得一分，選B得兩分，選C得三分，選D得四分，然後最後直接彈出結果，目前我遇到的問題是例如用戶在第一題選擇了A之後，如果之後他修改他的答案為B，那麼他的分數並不會減去一分再重新加兩分，請問能用什麼方法解決這個問題？謝謝

//僅針對你的單選題，且每道題目都設定了value
//雖然你說是十道而所貼代碼中為11道,長度依然取的10
他提交問卷的時候才把所有input的value值加起來不就可以了
其實不能這樣算。計算使用者的分數的時候就是重新統計一下，那麼如果這樣做的話，怎麼會出現-1+2這樣的情況。這可能是重新累加
若是10題選完後才彈出總分，可以在最後獲取所有題目的被選的答案對應的分數不就好了，沒必要選擇時立刻累加。
第11題，你怎麼點，分數都不加也不減。
因為你沒有對它計算，程式碼不用變化，把10改成11就可以了。
