Question

在为我的学校项目编写基本游戏时，我遇到了一个问题，试图存储和排序高分数组，我相信使用 localstorage 是正确的方式去，但由于数组本身由一个名称和一个分数组成，我在尝试排序时遇到了问题。

    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"));
    }
}

您可以将allPlayers添加为对象数组，例如

＆＃13;

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

＆＃13;

然后用分数对其进行排序，这样你就可以得到高分以及排序数组中该玩家的名字

＆＃13;

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);

＆＃13;

＆＃34; sortedPlayers＆＃34;将包含排名最高的排序数组

localStorage数组排序
