問題在于 player1 的 for 回圈內的提示。當我在提示框中輸入蛇時，它會給出錯誤“蛇未定義”。但是當我在 for 回圈之外嘗試時，它作業正常。請幫助我，我仍處于學習階段。

不，不是。問題是代碼試圖使用未定義的變數：
(player1 == snake && player2 == snake)
沒有名為 的變數snake。但是，有一個字串值 'snake'：
let element = ['snake', 'water', 'gun']
您的意思是將其與字串進行比較嗎？：
(player1 == 'snake' && player2 == 'snake')
或者也許與陣列元素？：
(player1 == element[0] && player2 == element[0])
