jquery toggle with cookie quick help

Question

Hopefully a quick fix after spending quite a few hours trying to get this to work:

Basically I to ONLY add the class "active" to .trigger anchor when when it has either been clicked or the cookie has made it open. And when the anchor is clicked again to close the container remove the class "active".

Here is my code. Thanks.

$(document).ready(function () {

            jQuery.cookie = function (name, value, options) { if (typeof value != 'undefined') { options = options || {}; if (value === null) { value = ''; options = $.extend({}, options); options.expires = -1; } var expires = ''; if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) { var date; if (typeof options.expires == 'number') { date = new Date(); date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000)); } else { date = options.expires; } expires = '; expires=' + date.toUTCString(); } var path = options.path ? '; path=' + (options.path) : ''; var domain = options.domain ? '; domain=' + (options.domain) : ''; var secure = options.secure ? '; secure' : ''; document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join(''); } else { var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } };

            $(".toggle_container").hide();

            $('.toggle_container').each(function () {
                $(this).toggle($.cookie('show-' + this.id) != 'collapsed');
            });

            $('.trigger').click(function () {
                var tc = $(this).toggleClass('active').next('.toggle_container').slideToggle('slow', function () {
                    $.cookie('show-' + $(this).attr('id'), $(this).is(':hidden') ? 'collapsed' : 'expanded');
                });
                return false;
            });

        });
