slitslider.js - open a specific div, not with arrow

I'm using Slit Slider js. This opens div slides with arrows and dots for navigation. Is there a way to create a link to open a specific slide? For example: Home, About Us etc. instead of arrows.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
$(function() {
var Page = (function() {
var $navArrows = $('#nav-arrows'),
$nav = $('#nav-dots > span'),
slitslider = $('#slider').slitslider({
onBeforeChange: function(slide, pos) {
$nav.removeClass('nav-dot-current');
$nav.eq(pos).addClass('na```v-dot-current');
}
}),
init = function() {
initEvents();
},
initEvents = function() {
// add navigation events
$navArrows.children(':last').on('click', function() {
slitslider.next();
return false;
});
$navArrows.children(':first').on('click', function() {
slitslider.previous();
return false;
});
$nav.each(function(i) {
$(this).on('click', function(event) {
var $dot = $(this);
if (!slitslider.isActive()) {
$nav.removeClass('nav-dot-current');
$dot.addClass('nav-dot-current');
}
slitslider.jump(i + 1);
return false;
});
});
};
return {
init: init
};
})();
Page.init();
});
Thanks for your support :)

how to add and than remove eventlistener in JavaScript

new_line=function()
{
var conteiner=document.createElement('div');
conteiner.classList.add('conteiner');
conteiner.addEventListener('click', function (event){on_click(event, conteiner);}, false);//this is an anonymous function so it is always new
document.body.appendChild(conteiner);
create_el(conteiner);
};
I have this function and in it addEventListener. I know that when I'm giving: function (event){on_click(event, conteiner);} I can't remove this EventListener, but I need give on_click function second parameter.
delete_conteiner=function(which)
{
which.removeEventListener("click", function (event){on_click(event, conteiner);}, false);//this isn't working
document.body.removeChild(which);
};
Is it posible to add EventListener, which execute on_click, and than remove it in oder EventListener? Here full code:

The removeEventListener() method removes an event handler that has been attached with the addEventListener() method.
Note: To remove event handlers, the function specified with the addEventListener() method must be an external function, like in the example below (click_event_func).
Anonymous functions, like "function (event){on_click(event, conteiner);}" will not work.
click_event_func = function(event) {
on_click(event, conteiner);
};
new_line = function() {
var conteiner = document.createElement('div');
conteiner.classList.add('conteiner');
conteiner.addEventListener('click', click_event_func, false);
document.body.appendChild(conteiner);
create_el(conteiner);
};
delete_conteiner = function(which) {
which.removeEventListener("click", click_event_func, false);
document.body.removeChild(which);
};

If you want to pass another param to an event listener you have to bind it to the function, as eventlistener will only pass the event itself (click event in your example). If you pass the exact same params and the same function when you remove it will remove it successfuly according to MDN.
https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/removeEventListener

I think your problem is you don't use named functions.
Try to do like this:
function NameHere(event) { on_click(event, conteiner); }
new_line=function() {
var conteiner=document.createElement('div');
conteiner.classList.add('conteiner');
conteiner.addEventListener('click', NameHere, false);
document.body.appendChild(conteiner);
create_el(conteiner);
};
delete_conteiner=function(which) {
which.removeEventListener("click", NameHere, false);//this isn't working
document.body.removeChild(which);
};
The problem is when you try to remove the listener without using names, you will remove a different function from the one you added before.

By example:
which.removeEventListener("click", function (event){on_click(event, conteiner);}, false);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// This here creates a new function. It's not related to
// the function you created with addEventListener earlier.
// Trying to remove it from eventlisteners on "which" is silly
// because it doesn't exist there.
Instead:
var eventHandler = function(event){on_click(event, conteiner);}; // Store for later
conteiner.addEventListener('click', eventHandler); // Add.
conteiner.removeEventListener('click', eventHandler); // Remove.
You can remove eventListeners as long as you referencing the same function.

How can I stop JS triggering when scrolling on touch devices

At the moment we are using the below script to create a lightweight lightbox for a wordpress site, which works perfectly on desktop, but the overlay is being triggered when just scrolling on a touch device if you scroll with your finger on one of the images, is there anyway to stop this happening?
<script>
var WHLightbox = {
settings: {
overlay: $('.portfolio-tile--overlay'),
imageCell: $('.cell-image, .portfolio-tile--image')
},
data: {
images: []
},
init: function() {
this.events();
this.buildImageData();
},
events: function() {
var self = this;
this.settings.imageCell.on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
// set up the overlay
self._positionOverlay();
self._openOverlay();
self._preventScrolling();
// create the image slide
self._createImageSlide($(this));
});
this.settings.overlay.on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
self._closeOverlay();
});
$('.portfolio-tile--overlay--controls--prev, .portfolio-tile--overlay--controls--next').on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
});
$('.portfolio-tile--overlay--controls--prev').on('click touchend', function(e) {

e.stopPropagation();
self.showPrev();
});
$('.portfolio-tile--overlay--controls--next').on('click touchend', function(e) {

self.showNext();
});
},
// public functions

}
this._createImageSlide(false, index-1);
},
showNext: function() {

},

if(this.settings.overlay.hasClass('open')) {
var imageUrl = $('.portfolio-tile--main-image').attr('src');

if(spanEl.length) {
imagePath = spanEl.css('backgroundImage');
imagePath = imagePath.replace('url(', '').replace(')', '');
} else if(imgEl.length) {
imagePath = imgEl.attr('src');
}
return imagePath;
},
// overlay
_positionOverlay: function() {

// position the overlay to current scroll position

});
},

};
WHLightbox.init();

You could use a library such as Modernizr to detect touch take a look at the answer to this question on detecting touch What's the best way to detect a 'touch screen' device using JavaScript?
With Modernizr only:
if (Modernizr.touch) {
alert('Touch Screen');
} else {
alert('No Touch Screen');
}
or with the use of jQuery & Modernizr you can do something like:
if($('html').hasClass('touch') === false) {
//run your code here
}

Thank you for your reply aharen, I managed to get it working by just changing touchend to tap and it seems to be working as intended now.

How to hide a section when click outside the section in my HTML page?

Please check it. Here is the Fiddle: http://jsfiddle.net/4467yz37/
When I do click in the Link it works good (Show and Hide). The only problem existing it's when I want to hide the Items section doing click outside the Link and the Items (that is in the Body except in the Items section).
Here is the JavaScript code:
(function(document) {
var alterNav = function() {
var item = document.querySelector('.items');
var link = document.querySelector('.clickme');
var theClass = 'display';
var itemIsOpened = false;
if (link) {
link.addEventListener('click', function (event) {
event.preventDefault();
if (!itemIsOpened) {
itemIsOpened = true;
addClass(item, theClass);
} else {
itemIsOpened = false;
removeClass(item, theClass);
}
});
}
};
var addClass = function (element, className) {
if (!element) {
return;
}
element.className = element.className.replace(/\s+$/gi, '') + ' ' + className;
};
var removeClass = function(element, className) {
if (!element) {
return;
}
element.className = element.className.replace(className, '');
};
alterNav();
})(document);
I try to solve it creating another variable with the tag Html or Body and alter the JS code, but it still don't working good: http://jsfiddle.net/g1d321rv/2/
var link = document.querySelector('body');

I manipulated your code a bit. Do you use jquery? I assumend that you are not using jquery.Here jsfiddle :
http://jsfiddle.net/9fpf07mt/
window.onclick = function (e) {
console.log(e);
if (!itemIsOpened) {
if (e.target == link) {
itemIsOpened = true;
addClass(item, theClass);
}
} else {
if (!isChild(e.target, item)) {
itemIsOpened = false;
removeClass(item, theClass);
}
}
};
edit for last request:
link.addEventListener('click', function (event) {
event.preventDefault();
});
