js获取cookie是数字

// 设置Cookie
function setCookie(name, value, days) {
    let expires = "";
    if (days) {
        const date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + encodeURIComponent(value) + expires + "; path=/";
}

// 获取Cookie
function getCookie(name) {
    const value = `; ${document.cookie}`;
    const parts = value.split(`; ${name}=`);
    if (parts.length === 2) return decodeURIComponent(parts.pop().split(';').shift());
}

// 使用示例
setCookie('username', 'John Doe', 7);
setCookie('score', 100, 7);

console.log(getCookie('username')); // 输出: John Doe
console.log(getCookie('score')); // 输出: 100
