使用直線JS與玩家對cpu設置進行井字遊戲。我試圖找出一個隨機函數的CPU轉。它正在打破這個功能，並通過它。 console.log（cpuTurn（））;在玩家標出正方形後總是返回false。 （我==「」）blanks.push（[我]）;我有一個問題，我認爲這是一個問題：if（i ==「」）blanks.push（[i]）;如果我聲明一個像Val這樣的變量，並把它放在前面，就像這樣：if（Val（i）==「」）...我會得到一個錯誤，說明'Val'不是函數。針對井字遊戲不能正常工作的隨機javascript AI功能
我以什麼我需要在這裏做完全糊塗了......

熟悉的調試器，它應該是很容易步執行代碼，看看發生了什麼。 –
var Val = 0;你正在使用它像Val（i）？ –
'i =='「'整數與字符串相比如何？ –
