四択クイズを作成するJavaScriptコード・選択肢はランダム表示バージョン
＊＊＊変更＊＊＊とコメントアウトされている部分を変更して使って下さい。全部で二箇所あります。 出題数は、全問題の中から実際に何問出題するかを入力します。 出題する問題と答えについては、中が空欄になっているカッコの部分に、下の例のように入力して下さい。
["use(ユーズ)","使う"],
["()",""],
当サイトで掲載している英単語問題では、()の前に単語を入れ、カッコの中にカタカナで読み方を入れています。 読み方を入れない場合は最初の()を消してください。 後ろの""で囲まれている中には、正解の選択肢を入力します。 出題時には、入力されている全ての選択肢から、ランダムで3つの間違いの選択肢が選ばれます。
["()",""],
