クイズを作成するが、Javaは答えをチェックしないでください

私はテストをしようとしていますが、何らかの理由でコードを返答をチェックして数値グレードと文字グレードを返してください。私はこの問題を数時間修正しようとしましたが、何が問題なのかわかりません。ボタンが関数に接続されていないか、または関数が形式のエラーのため応答を計算できません。クイズを作成するが、Javaは答えをチェックしないでください

フォームとJavaScriptは、それらのエラーを持っています。私はそれをきれいにした。ほとんどの場合、入力変数を使用できるように、 "質問"変数をフォームにバインドする必要があります。

ラジオボタンにグループを追加すると、人々は同時に真偽を選択できなくなります。ハッピーコーディング。

このサンプルコードでは、いくつかの方向を見てみましょう。あなたが持っていた問題のいくつか： 1）あなたのコードには、ハンドラ関数にバインドするための正しいhtmlがありませんでした。 2）コード内でフォーム内のコントロールを取得できませんでした。 3）あなたのコードは、出力フィールドをフォームの一部として扱っていませんでした。

さらに進んでください。
