jQuery Toggle with Cookie

Question

I have the following toggle system, but I want it to remember what was open/closed using the jQuery cookie plugin. So for example if I open a toggle and then navigate away from the page, when I come back it should be still open. By default all Toggles should be closed.

This is code I have so far, but it's becoming rather confusing, some help would be much appreciated thanks.

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; } };
        // var showTop = $.cookie('showTop');
        if ($.cookie('showTop') == 'collapsed') {

            $(".toggle_container").hide();
            $(".trigger").toggle(function () {
                $(this).addClass("active");
            }, function () {
                $(this).removeClass("active");
            });
            $(".trigger").click(function () {
                $(this).next(".toggle_container").slideToggle("slow,");
            });
        } else {

            $(".toggle_container").show();
            $(".trigger").toggle(function () {
                $(this).addClass("active");
            }, function () {
                $(this).removeClass("active");
            });
            $(".trigger").click(function () {
                $(this).next(".toggle_container").slideToggle("slow,");
            });
        };

        $(".trigger").click(function () {
            if ($(".toggle_container").is(":hidden")) {
                $(this).next(".toggle_container").slideToggle("slow,");
                $.cookie('showTop', 'expanded');
            } else {
                $(this).next(".toggle_container").slideToggle("slow,");
                $.cookie('showTop', 'collapsed');
            }

            return false;

        });

and this is a snippet of the HTML it works with:

<li> 
                                        <label for="small"><input type="checkbox" id="small" /> Small</label> 
                                        <a class="trigger" href="#">Toggle</a>  
                                        <div class="toggle_container"> 
                                            <p class="funding"><strong>Funding</strong></p> 
                                            <ul class="childs"> 
                                                <li class="child"> 
                                                    <label for="fully-funded1"><input type="checkbox" id="fully-funded1" /> Fully Funded</label> 
                                                    <a class="trigger" href="#">Toggle</a> 
                                                    <div class="toggle_container"> 
                                                        <p class="days"><strong>Days</strong></p> 
                                                        <ul class="days clearfix"> 
                                                            <li><label for="1pre16">Pre 16</label> <input type="text" id="1pre16" /></li> 
                                                            <li><label for="2post16">Post 16</label> <input type="text" id="2post16" /></li> 
                                                            <li><label for="3teacher">Teacher</label> <input type="text" id="3teacher" /></li> 
                                                        </ul> 
                                                    </div> 
                                                </li>

Answer 1

You can shorten all that code down to this, should keep it much simpler:

$(".toggle_container").toggle($.cookie('showTop') != 'collapsed');

$(".trigger").click(function () {
    $(this).toggleClass("active").next(".toggle_container").slideToggle("slow,");
    $.cookie('showTop', 
                $(".toggle_container").is(":hidden") ? 'expanded' : 'collapsed');
    return false;
});

Here's an approach that sets a cookie for each container, all that's necessary is to give each .toggle_container a unique ID:

$(".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;
});​

Answer 2

Removing clutter...

Answer 3

For some reason the comment box has disappeared for me??? I have given the containers unique ID's but the toggles no longer work. Not sure why.

Answer 4

Okay this is the code I have:

The stuff commented out worked fine, but didn't talk to unique ID's. The code above that doesn't work.

$(document).ready(function () {

        $(".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;
        });​

        //$(".toggle_container").toggle($.cookie('showTop') != 'collapsed');

        /*$(".trigger").click(function () {
            $(this).toggleClass("active").next(".toggle_container").slideToggle("slow,");
            $.cookie('showTop',
            $(".toggle_container").is(":hidden") ? 'expanded' : 'collapsed');
            return false;
        });*/

    });

and this is the HTML

                            <li> 
                    <input id="MC_ctl00_RPS_chkItem_1" type="checkbox" name="ctl00$MC$ctl00$RPS$ctl01$chkItem" /> 
                    <label for="MC_ctl00_RPS_chkItem_1" id="MC_ctl00_RPS_lbl_1">Medium</label> 
                    <a class="trigger" href="#">Toggle</a>  
                    <div class="toggle_container" id="divFund"> 
                        <p class="funding"><strong>Funding</strong></p> 
                        <ul class="childs"> 

                                <li class="child">
