私はクイズの静的HTMLページを作成しました。続き は、私は、ユーザーが、正しいと一緒にすべての答えを保存したい .txtファイルにすべてが正常に動作しているが、私がチェックし、ラジオボタンの値と最終結果を保存したい私のコードJavaScriptを使用してHTMLページコンテンツを.txtファイルに保存する方法は？

です間違っている。
にラジオの値を追加 - .valueを使用して、配列にして最終的なスコア？ –
Rico
document.getElementById("question").text;はdocument.getElementById("question").innerHTML;であるべき
あなたは私にコード – stone
を教えてもらえますか？申し訳ありません。あなたが投稿したコードは、私がうんざりを与えている、私はそれを読むことができません:)） – Rico
