代码
//获取存储缓存json字符串并转换为数组
var playersArray = JSON.parse(sessionStorage.getItem("playersArray"));
//获取玩家数量并转换为number
var players = +sessionStorage.getItem("players");
//选择的玩家
var choosePlayer;
//存储玩家存活状态
var playerLife;
//获取平民数
var villager = sessionStorage.getItem("villager");
if (sessionStorage.getItem("playerLife") != null) {
    playerLife = JSON.parse(sessionStorage.getItem("playerLife"));
} else {
    playerLife = new Array(players);
}
$(function () {
    console.log(players);
    console.log(playersArray);
    //进行元素克隆、默认有一个，只需要克隆数量-1个
    for (var i = 0; i < players - 1; i++) {
        $("#player1").clone().attr("id", "player" + (i + 2)).appendTo("div.players");
    };
    // 对克隆元素内部进行内容修改
    for (var i = 0; i < players; i++) {
        //更改序号
        var id = "#player" + (i + 1);
        $(id).find("p.number").text((i + 1) + "号");
