Javascript help needed, store local variable

As Javascript newbie I'm not able to store locally a variable and reuse from Google cache.
I have a counter that starts onClick from zero then increments until a specific number then goes to a new page.
In the new page I need to continue the counter from the previous number.
I can't use cookies since this is for a Chrome extension, so I used storage.local and I set my manifest as follow:
...
"permissions": ["storage", "https://example.com/*", "unlimitedStorage"],
"content_scripts": [
{
"matches": ["https://example.com/*"],
"js": ["js/jquery-2.1.4.min.js", "js/example.js"],
"css": ["css/example.css"]
}
],
...
So basically when I click my button it starts the follow function and it increments this.count
function Button(t, e, i) {
var n = this;
n.$el = t,
n.count = (Record.get(function() {tmf.followBtn.counter()}) > 1 ? Record.get(function() {tmf.followBtn.counter()}) : 0),
n.$title = t.find(".tmf-btn__title"),
n.$subtitle = t.find(".tmf-btn__subtitle"),
n.action = new BulkAction(e, i), n.$el.on("click", function() {
n.$el.addClass("tmf-btn--active"),
n.$title.text(n.count),
n.action.paused ? (n.action.proceed(), n.$subtitle.text("Click to pause")) : (n.action.pause(), n.$subtitle.text("Click to continue"))
})
}
function Profile(t) {
this.$el = $(".ProfileCard:eq(" + t + ")"),
this.isLoaded() && (this.$btn = this.$el.find(".user-actions-follow-button"),
this.id = this.$el.data("user-id") + "-")
}
function BulkAction(t, e) {
this.callback = t,
this.interval = e,
this.paused = !0
}
function gotoPage() {
window.location.replace("https://example.com/newpage/");
}
$.fn.isPresent = function() {
return this.length > 0
};
var USER_ID = $("#user-dropdown").find("[data-user-id]").data("user-id"),
Record = {
storage: chrome.storage.local,
key: USER_ID.toString(),
get: function(t) {
var e = this;
this.storage.get(this.key, function(i) {
e.result = i, t.call()
})
},
set: function() {
this.storage.set(this.result)
},
add: function(t) {
this.result[this.key] ? this.result[this.key] += t : this.result[this.key] = t, this.set()
},
includes: function(t) {
return this.result[this.key] ? this.result[this.key].includes(t) : !1
}
},
tmf = {
init: function() {
var t = this;
t.$el = $("<div>").addClass("tmf animated").appendTo("body")
},
toggle: function() {
var t = this;
this.$el.removeClass("flipInY flipOutY tmf--active"), $(".ProfileCard").length > 10 ? t.$el.load(chrome.extension.getURL("html/actions.html"), {}, function() {
$(".tmf-btn").on("click", function() {
t.$el.addClass("tmf--active")
}), t.followBtn = new Button($(".tmf-btn--follow"), function() {
this.follow()
}, 100), t.unfollowBtn = new Button($(".tmf-btn--unfollow"), function() {
this.unfollow()
}, 100), t.$el.addClass("flipInY");
var e = new MutationObserver(function(e) {
e.forEach(function(e) {
var i = $("#message-drawer").html();
i.includes("66885") && t.followBtn.setIdle()
})
});
e.observe(document.getElementById("message-drawer"), {

$(".flipInY").hide();
});
observer.observe(document.querySelector("head > title"), {
subtree: !0,
characterData: !0,
childList: !0
});
I need to store locally my counter, so as you can see I tried to set it as:
Record.set(function() {tmf.followBtn.counter()}); inside my follow function.
Then I tried to get it from my Button function as:
n.count = (Record.get(function() {tmf.followBtn.counter()}) > 1 ? Record.get(function() {tmf.followBtn.counter()}) : 0),
Why all the time I reload the page, the counter starts from zero?

make jquery default collapse

i have phpbb 3.1 forum.
i have a- jquery.collapse.js.
i want that the defult will be collapsed insted of open.
wheat parameter do i need to change to do it?
and can o make it that in default only 1 is open and not close?
the default will be the 1st category to be open, and when i open the next one, the open one will close automatically.
the code-

Soundcloud stratus player won't dynamically add more than an individual track at a time

Thanks to other people's questions, I have gotten AJAX links to work for individual songs when clicked in the DOM. My problem is that I need to find a way to load all of the tracks under a given user's account on soundcloud. I edited the stratus.js file to make it listen for the click by using .delegate(), but I can't figure out how to call the track listing from soundcloud and load it through the given iframe. This is the stratus.js file.
(function() {
var $;
$ = jQuery;
(function($){var g,d,j=1,a,b=this,f=!1,h="postMessage",e="addEventListener",c,i=b[h]&&!$.browser.opera;$[h]=function(k,l,m){if(!l){return}k=typeof k==="string"?k:$.param(k);m=m||parent; if(i){m[h](k,l.replace(/([^:]+:\/\/[^\/]+).*/,"$1"))}else{if(l){m.location=l.replace(/#.*$/,"")+"#"+(+new Date)+(j++)+"&"+k}}};$.receiveMessage=c=function(l,m,k){if(i){if(l){a&&c(); a=function(n){if((typeof m==="string"&&n.origin!==m)||($.isFunction(m)&&m(n.origin)===f)){return f}l(n)}}if(b[e]){b[l?e:"removeEventListener"]("message",a,f)} else{b[l?"attachEvent":"detachEvent"]("onmessage",a)}}else{g&&clearInterval(g);g=null;if(l){k=typeof m==="number"?m:typeof k==="number"?k:100; g=setInterval(function(){var o=document.location.hash,n=/^#?\d+&/;if(o!==d&&n.test(o)){d=o;l({data:o.replace(n,"")})}},k)}}}})(jQuery);
$.fn.stratus = function(settings) {
return $.stratus(settings);
};
$.stratus = function(settings) {
var root_url, src;
root_url = settings.env === 'development' ? 'http://example.com:3000' : 'http://stratus.sc';
$('head').append("<link rel='stylesheet' href='" + root_url + "/stratus.css' type='text/css'/>");
if (settings.align === 'top') {
$('head').append("<style>#stratus{ top: 0; }</style>");
}
if (settings.position === 'absolute') {
$('head').append("<style>#stratus{ position: absolute; }</style>");
}
if (settings.offset) {
$('head').append("<style>#stratus{ " + settings.align + ": " + settings.offset + "px !important; }</style>");
}
$('body').append("<div id='stratus'><iframe allowtransparency='true' frameborder='0' scrolling='0'></div>");
src = root_url + '/player?' + $.param(settings, true) + '&link=' + encodeURIComponent(document.location.href);
$('#stratus iframe').attr({
src: src
});
$('#stratus iframe').load(function() {// /resolve?url=
return $(this).css({
visibility: 'visible'
});
});
$('#stratus').show();
$(document).delegate("a.stratus","click", function () {
$.postMessage($(this).attr('href'), src, $('#stratus iframe')[0].contentWindow);
return false;
});
return $.receiveMessage(function(e) {
return $('#stratus').toggleClass('open');
}, root_url);
};
}).call(this);
I believe that a call through the Soundcloud API will be necessary, then a run through the user data for individual track additions through the iframe. This is the player.js file, which I'm not sure is necessary for this post, but it helped me begin to understand what was happening with the initial adding of tracks from the customisable Links field:

I'm aware that this is rather intensive, and I apologize for that. Just throwing up a prayer that I won't have to radically alter my website user's experience in a negative way.

I don't know about the stratus player, but in general - if you want to retrieve a list of tracks of a specific user - given that you know the user's id, you indeed have to make a call to the soundcloud API. You can do it like this:
SC.initialize({
client_id: "YOUR_CLIENT_ID",
redirect_uri: "http://example.com/callback.html",
});
/**
Once that's done you are all set and ready to call the SoundCloud API.
**/
/**
Call to the SoundCloud API.
Retrieves list of tracks, and displays a list with links to the tracks showing 'tracktitle' and 'track duration'
**/
var userId = 39090345; // user_id of Prutsonic
SC.get("/tracks", {
user_id: userId,
limit: 100
}, function (tracks) {
for (var i = 0; i < tracks.length; i++) {
console.log(tracks[i].title);
}
});
You can try my fiddle here: http://jsfiddle.net/tobiasbeuving/26pHX/5/

TypeScript - JavaScript using knockout.js not working in IE8 - "Object doesn't support this property or method"

I have this code (also shown below) that is giving me an error in IE8 but is fine in Chrome and PhantomJS.
The error is "Object doesn't support this property or method knockout-2.2.1.debug.js, line 2319 character 35", which is called from currentPage(pages[pages.indexOf(current) + steps]);
I have no clue why it's not working, so any help would be greatly appreciated!

indexOf in IE8 does not supported, use $.inArray
