js cookie 设置多个值

// 设置单个Cookie
document.cookie = "username=John Doe; expires=Thu, 18 Dec 2023 12:00:00 UTC; path=/";

// 设置多个Cookie
document.cookie = "name=John";
document.cookie = "age=30";
document.cookie = "email=john@example.com";

// 或者在同一个Cookie中存储多个值，使用分隔符
document.cookie = "user_info=name:John,age:30,email:john@example.com";

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

setCookie("user_info", "name:John,age:30,email:john@example.com", 7);
