cookie.js

网上看到操作cookie的一个javascript类库。

var Cookie = {
    set: function(name, value, daysToExpire) {
        var expire = '';
        var path = '; path=/';
        if (daysToExpire != undefined) {
            var d = new Date();
            d.setTime(d.getTime() + (86400000 * parseFloat(daysToExpire)));
            expire = '; expires=' + d.toGMTString();
        }
        return (document.cookie = escape(name) + '=' + escape(value || '') + expire + path);
    },
    get: function(name) {
        var cookie = document.cookie.match(new RegExp('(^|;)\\s*' + escape(name) + '=([^;\\s]*)'));
        return (cookie ? unescape(cookie[2]) : null);
    },
    erase: function(name) {
        var cookie = Cookie.get(name) || true;
        Cookie.set(name, '', -1);
        return cookie;
    },
    accept: function() {
        if (typeof navigator.cookieEnabled == 'boolean') {
            return navigator.cookieEnabled;
        }
        Cookie.set('_test', '1');
        return (Cookie.erase('_test') === '1');
    }
};
