简介：
我正在尝试制作石头、纸和剪刀(rps(。
问题：
我正在尝试在我的功能中保存两个不同的选项，以便我可以制作一个功能游戏。然而，每次我的数组被重置时。这使得我不能使用rps的用户输入。
当前代码：
function game(input) {
var playerMoves = [];
if (playerMoves.length < 2) {
playerMoves.push(input);
} else {
playerMoves = [];
}
console.log(playerMoves);
}h1 {
text-align: center;
}
button {
font-size: 1.2rem;
}
#player_turn {
color: rgb(255, 0, 0);
}
.container {
display: flex;
width: 100%;
flex-direction: row;
justify-content: space-around;
}
.images {
width: 200px;
cursor: pointer;

"；Dev"；注意：
如果您认为任何东西已经过时/没有用处。请注意，我对所有类型的输入都持100%的开放态度。
将playerMoves声明移出函数：
var playerMoves = []
function game(input) {
if (playerMoves.length < 2) {
playerMoves.push(input);
console.log(playerMoves);
} else {
playerMoves = [];
}
}h1 {
text-align: center;
}
button {
font-size: 1.2rem;
}
#player_turn {
color: rgb(255, 0, 0);
}
.container {
display: flex;
width: 100%;
flex-direction: row;
justify-content: space-around;
}
.images {
width: 200px;
cursor: pointer;
