存储：cookie,localstorage

创建模块：

(function () {
    /**
     * FCZX.foo.bar
     */
    let FCZX = {};
    FCZX.globalNamespace = function (ns) {
        var nsParts = ns.split(".");
        var root = window;
        for (var i = 0; i < nsParts.length; i++) {
            if (typeof root[nsParts[i]] == "undefined") {
                root[nsParts[i]] = {};
            }
            root = root[nsParts[i]];
        }
        return root;
    }

    window.FCZX = FCZX;
})();

简单加密：

(function () {
    FCZX.globalNamespace('FCZX.Encript');

    FCZX.Encript.encode = function (value) {
        if (value) {
            return btoa(encodeURIComponent(JSON.stringify(value)))
        }
    }

    FCZX.Encript.decode = function (value) {
        if (value) {
            return JSON.parse(decodeURIComponent(atob(value)))
        }
    }
})();

localstorage:

(function (win) {
    FCZX.globalNamespace('FCZX.Store');

    FCZX.Store.setItem = function (key, value) {
        win.localStorage.setItem(key, FCZX.Encript.encode(value))
    }

    FCZX.Store.getItem = function (key) {
        let value = win.localStorage.getItem(key)
        if (value) {
            return FCZX.Encript.decode(value)
        }
    }

    FCZX.Store.clear = function (key) {
        key ? win.localStorage.removeItem(key) : win.localStorage.clear();
    }
})(window);

cookie:

setCookie = function (key, value, expires, domain, path = "/") {
    let today = new Date();
    today.setTime(today.getTime());
    if (expires) {
        expires = expires * 1000 * 60 * 60 * 24;
    }
    let expiresDate = new Date(today.getTime() + (expires));

    document.cookie = key + "=" + escape(value) +
        ((expires) ? ";expires=" + expiresDate.toGMTString() : "") +
        ((path) ? ";path=" + path : "") +
        ((domain) ? ";domain=" + domain : "");
}

getCookie = function (key) {
    var allCookies = document.cookie.split(';');
    var cookieKey = '';
    var cookieValue = '';
    var tempCookie = '';
    var isFound = false;

    for (const item of allCookies) {
        tempCookie = item.split('=');
        cookieKey = tempCookie[0].replace(/^s+|s+$/g, '');
        if (cookieKey == key) {
            isFound = true;
            if (tempCookie.length > 1) {
                cookieValue = unescape(tempCookie[1].replace(/^s+|s+$/g, ''));
            }
            return cookieValue
        }
        cookieKey = '';
        tempCookie = null;
    }
    if (!isFound) {
        return null
    }
}

deleteCookie = function (key, domain, path = '/') {
    if (app.getCookie(key)) {
        document.cookie = key + "=" +
            ((path) ? ";path=" + path : "") +
            ((domain) ? ";domain=" + domain : "") + ";expires=Thu, 01-Jan-1970 00:00:01 GMT";
    }
}

getToken = function () {
    var arr, reg = new RegExp("(^| )_x_token=([^;]*)(;|$)");
    if (arr = document.cookie.match(reg)) {
        return unescape(arr[2]);
    } else {
        return undefined;
    }
};
