你判断一下 你的 chessArr[i][j] 值
if (chessArr[i][j] == 0) { drawChess(i, j, me); if (me) { chessArr[i][j] = 1; } else { chessArr[i][j] = 2; } me = !me; for (var k = 0; k < count; k++) { if (wins[i][j][k]) { if(chessArr[i][j] == 1 ){ //这个表示我方赢了 myWin[k]++; computerWin[k] = 6; if (myWin[k] == 5) { window.alert("you win !!!"); over = true; } }else{ myWin[k] = 6; computerWin[k] ++ ; if (computerWin[k] == 5) { window.alert("计算机赢了"); over = true; } } } }}
