Question

我目前正在尝试使用JQuery cookie插件在cookie userScoreCookie中存储变量userScore。当我在console.log中时，打印数据的内容是'undefined'。造成这种情况的原因是什么？

var cookieValue;
var userScore = 0;
$.cookie('userScoreCookie', 'userScore', {path: '/',expires: 365});
cookieValue = $.cookie("userScoreCookie");
console.log("cookie score: " + cookieValue);
