Get/Set the index of the last opened li using jquery

I am using an accordion and trying to achieve the below:
Every time there is a post back, display/expand the last opened/active li that was shown before. At the moment, the page is refreshed and go back to its initial stage (all li closed). Is it possible to achieve this ?
I tried different things but without success e.g. I tried to save the last opened/active li index into a hidden aspx text box but it didn't work. Also, I tried to save the index in a cookie but again without success.
$('#st-accordion').accordion({
open: -1
});
Can I replace the -1 with a dynamic way of getting the index of the last opened li without losing it after post back ? In addition, how can I handle situations that more than one li were opened/expanded.
Any ideas would be much appreciated.

You can use sessionStorage in order to save some js variables with the last opened/expanded li, you can set it on open/expand event:
sessionStorage.SessionName = "SessionName";
sessionStorage.getItem("SessionName");
sessionStorage.setItem("SessionName","10");
Or you can use cookies (client side):
document.cookie

How Can i call from external js file

I have a javascript file that contains the following objects and functions........

The question I have is how do I call the object _resetMenu in another script. to my poor knowledge it should be ......
window.mlPushMenu._resetMenu();
that should execute that object in my mind but it isn't working so clealy I am wrong ... Any help here would be much appreciated..
this is the example of the button I have created thus far.....
$('.iconM-referrals').on('click', function () {
window.mlPushMenu._resetMenu();
$("#colorscreen").remove();
$("body").append('<div id="colorscreen" class="animated"></div>');
$("#colorscreen").addClass("fadeInUpBig");
$('.fadeInUpBig').css('background-color', 'rgba(13,135,22,0.3)');

The way you have mlPushMenu set up is as a Constructor, not as a stand-alone module. (See: Any tutorial on Object-Oriented programming) You'd need to construct an instance variable to call the function. For instance:
myInstanceOfPushMenu = new mlPushMenu();
myInstanceOfPushMenu._resetMenu();
This, however, is assuming that the script inclusion and declaration, and anything left out of your question, is all set up properly.

how to i reuse specifically and only the close object in a line of code somewhere else ?
.... I am just trying to append the close object defined in the above code somewhere else so i can use it with some other code.
the example of where i am trying to use it .....
$('.iconM-referrals').on('click', function () {
$("#colorscreen").remove()
$("body").append('<div id="colorscreen" class="animated"></div>')
$("#colorscreen").addClass("fadeInUpBig");
$('.fadeInUpBig').css('background-color', 'rgba(13,135,22,0.3)');
$(".tile-group.main").css({ width: "720px"}).load("musability-musictherapy-company-overview.html");
$window.mlPushMenu._closeMenu;
});

as i see you can use window.mlPushMenu in any where you want in your html document cause this was set as global in window object.
and if you want to use close function you can call window.mlPushMenu._closeMenu
hope it helps.

At the end is this:
// add to global namespace
window.mlPushMenu = mlPushMenu;
Use window.mlPushMenu

Target ID instead of <li>

I am working on JavaScript accordion and somehow i struck on targeting accordion ID instead of its <li>
Basically, I want below to generate two accordion if there are two markups like this
<div id="st-accordion" class="st-accordion">
<ul>
<li>
{tag_name_nolink}
<div class="st-content">
{tag_Partners Module tag}
</div>
</li>
</ul>
</div>
If there are two <div id="st-accordion" class="st-accordion">.......</div> then it should display two working accordions but it is making two working accordions when there are two <li> in the div.
Here is the JS and Fiddles

somebody help please?

You have 2 elements with the same ID, and ID must be unique, so all you have to do is using class instead of ID :
$(function() {
$('.st-accordion').accordion({
oneOpenedItem : true
});
});
here is the jsFiddle

How can I add a css element change to an onlick event in this jquery lib?

I've got this awesome slideshow library working just fine on my site (yoinked from codrops), but since I'm shifting between different pieces of information, I want to really call out the difference by adding a CSS change so that the background color matches the color of the content in the slide. Now, this is a library, so i figure I need to add the $('body').css call into it, and not my html doc. I'm including the code below, with a note marking where I think it's supposed to go. I'm jsut not sure what the exact phrasing would be since I've never worked inside a lib before. Any suggestions would be welcome!

Answered my own question with a little digging.
