localstorage阵列排序

Question

在为我的学校项目编码基本游戏时，我会遇到一个问题，试图存储和排序 highScore 数组，我相信使用>localstorage 是正确的方法

https://jsbin.com/fagupohozo/1/edit?js

    allPlayers = {};
function showScore(){
    getStoragePlayer();
    addPlayer();
    setStoragePlayer();
}
function addPlayer(){ //Adds a player to the array with score and name
    allPlayers[prompt("What's your name")] = score;
}
function setStoragePlayer(){ // Sends the array to the cloud for saving
    localStorage.setItem("PlayerArray", JSON.stringify(allPlayers));
}
function getStoragePlayer() { // Downloads the array from the cloud
    if (localStorage.PlayerArray != null) {
        allPlayers = JSON.parse(localStorage.getItem("PlayerArray"));
    }
}

您可以添加所有播放器作为

之类的对象数组

allPlayers = [
  {name:"John", score:20},
  {name:"Smith", score:40}
]

，然后用分数对其进行排序，以便您在排序阵列中获得高分以及该播放器的名称

var allPlayers = [
      {name:"John", score:20},
      {name:"Smith", score:40}
    ];
    var sortedPlayers = allPlayers.sort(function(a, b){
      return b.score - a.score
    });
    console.log(sortedPlayers);
