<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-cookie/1.4.1/jquery.cookie.min.js"></script>

// 设置或修改 Cookie
$.cookie('cookieName', 'newValue', { expires: 7, path: '/' });

// 读取 Cookie
var cookieValue = $.cookie('cookieName');
console.log(cookieValue);

// 设置或修改 Cookie
document.cookie = "cookieName=newValue; expires=Thu, 18 Dec 2023 12:00:00 UTC; path=/";

// 读取 Cookie
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
    var cookie = cookies[i].trim();
    if (cookie.indexOf("cookieName=") == 0) {
        var cookieValue = cookie.substring("cookieName=".length, cookie.length);
        console.log(cookieValue);
    }
}

// 使用 jquery.cookie 库修改 Cookie
$.cookie('cookieName', 'newValue', { expires: 7, path: '/' });

// 使用原生 JavaScript 修改 Cookie
document.cookie = "cookieName=newValue; expires=Thu, 18 Dec 2023 12:00:00 UTC; path=/";
