Javascript 在我使用Phaser制作的游戏中，我试图宣布胜利者，但它不断重复警报

我一直试图提醒玩家，如果玩家1赢了，那么提醒玩家1赢了，但它会不断弹出，直到你点击停止显示此对话

另外，当我添加到检测第二个玩家时，它就是不起作用

function detectWin () {
    if (score + playerTwoScore == 5900 && score > playerTwoScore) {
        alert("Player 1 Wins!");
    }
}

detectWin();

而且，当我这样做时，显示玩家2获胜是不起作用的

function detectWin () {
    if (score + playerTwoScore == 5900 && score > playerTwoScore) {
        alert("Player 1 Wins!");
    } else (score + playerTwoScore == 5900 && score < playerTwoScore) {
        alert("Player 2 Wins!");
  }
}
 detectWin();

函数（）{
如果（分数+playerTwoScore==5900&&score>playerTwoScore）{
警报（“玩家1获胜！”）；
}其他（分数+playerTwoScore==5900&&score
