使用cookie将用户信息从一个剃刀页面传送到另一个页面

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 = name + "=" + (value || "") + expires + "; path=/";
}

// 使用示例
setCookie('userInfo', JSON.stringify({username: 'JohnDoe', age: 30}), 7);

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

// 使用示例
var userInfo = JSON.parse(getCookie('userInfo'));
console.log(userInfo); // 输出: {username: "JohnDoe", age: 30}
