私がやっていることは、ページ内でシンプルな紙、岩、はさみのゲームをシミュレートすることです。ラジオボタンでr/p/sを選択し、プレーヤー2は同じことをします。javacript関数で正しい値を返す問題
このコードには複数の問題がありますが、ロック/ペーパー/ハサミを解決する機能を実行しようとするたびに、私は本当に奇妙なものが返ってきます。
else if (player1Choice("Rock") && player2Choice("Scissors")) {
$("resultOutput").value = "Player 1s Rock beats Player 2s Scissors";
}
いつも私はこの結果を私の結果として得ています。私は関数を見てきたので、私はおそらく、現時点で明らかな解決策についてはあまり気にしていません。
