一昨年、JavaScriptの授業を受けて合格し、今は夏休みです。使用した本は JavaScript 第 8 版、Tom Negrino、Dori Smith です。名前ジェネレーターのコードがあります。必要なものはすべてこの本にあります (p. 301)。名前と姓が必要ですが、別のばかげた名前を出力するためにミドル ネームを追加したかったのです。これは宿題ではなく、私がやってみたかったことです。姓または名を空白のままにすると、「有効な名前ではありません」というメッセージが表示されます。そこで私はミドルネームをコード化し、ミドルネームに 26 語を入力しましたが、コードは姓と名以外を認識しませんでした。私にはこれが機能するように見えますが、それでも姓と名のみが機能します。たぶん、別の目で、私が見逃したものや含まれていないものを見ることができるかもしれません.

提案をありがとう、CK
