Coding conflict between two javascript files

I'm trying to get a Jekyll site setup and I want the navigation to hide when scrolling down and show when scrolling up. I also want to setup ajax loading with pushState so that I can animate page transitions. I had the navigation hiding and showing properly with scrolling until I put in the code for doing the ajax loading. Now, the navigation will hide and show properly until I click a link, then it stays shown no matter what.
I'm assuming its breaking because I'm using two different jQuery libraries, however the navigation won't work on v2 and the ajax loading won't work on v3. They both work when used on their own. I could really use some help with this.
This is what my HTML looks like for loading the files:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/history.js/1.8/bundled/html4+html5/jquery.history.js"></script>
<script src="js/ajax.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="js/hide-navigation.js"></script>
Here is the navigation.js
jQuery(document).ready(function($){
var mainHeader = $('.cd-auto-hide-header'),
secondaryNavigation = $('.cd-secondary-nav'),
//this applies only if secondary nav is below intro section
belowNavHeroContent = $('.sub-nav-hero'),
headerHeight = mainHeader.height();
var isLateralNavAnimating = false;
//set scrolling variables
var scrolling = false,
previousTop = 0,
currentTop = 0,
scrollDelta = 10,
scrollOffset = 0;
mainHeader.on('click', '.nav-trigger', function(event){
// open primary navigation on mobile
event.preventDefault();
if( !isLateralNavAnimating ) {
if($(this).parents('.csstransitions').length >= 0 ) isLateralNavAnimating = true;
mainHeader.toggleClass('nav-open');
$('.cd-navigation-wrapper').one('webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend', function(){
//animation is over
isLateralNavAnimating = false;
});
}
});
$(window).on('scroll', function(){
if( !scrolling && !mainHeader.hasClass("nav-open")) {
scrolling = true;
(!window.requestAnimationFrame)
? setTimeout(autoHideHeader, 250)
: requestAnimationFrame(autoHideHeader);
}
});
$(window).on('resize', function(){
headerHeight = mainHeader.height();
});
function autoHideHeader() {
var currentTop = $(window).scrollTop();
( belowNavHeroContent.length > 0 )
? checkStickyNavigation(currentTop) // secondary navigation below intro
: checkSimpleNavigation(currentTop);
previousTop = currentTop;
scrolling = false;
}
function checkSimpleNavigation(currentTop) {
//there's no secondary nav or secondary nav is below primary nav
if (previousTop - currentTop > scrollDelta) {
//if scrolling up...
mainHeader.removeClass('is-hidden');
} else if( currentTop - previousTop > scrollDelta && currentTop > scrollOffset) {
//if scrolling down...
mainHeader.addClass('is-hidden');
}
}
function checkStickyNavigation(currentTop) {
//secondary nav below intro section - sticky secondary nav
var secondaryNavOffsetTop = belowNavHeroContent.offset().top - secondaryNavigation.height() - mainHeader.height();
if (previousTop >= currentTop ) {
//if scrolling up...
if( currentTop < secondaryNavOffsetTop ) {
//secondary nav is not fixed
mainHeader.removeClass('is-hidden');
secondaryNavigation.removeClass('fixed slide-up');
belowNavHeroContent.removeClass('secondary-nav-fixed');
} else if( previousTop - currentTop > scrollDelta ) {

Links works only in submenu

I'm trying to modify the following code becouse the links works only in a submenu , but i want to have some links in mainmenu too.
I found that when I use
$menuItems = $listItems.children(‘a.dropdown’);
instead of
$menuItems = $listItems.children( 'a' ),
...links from the main menu work fine , but logically submenu does not open.
Whole code:
var cbpHorizontalMenu = (function() {
var $listItems = $( '#cbp-hrmenu > ul > li' ),
$menuItems = $listItems.children( 'a' ),
$body = $( 'body' ),
current = -1;
function init() {
$menuItems.on( 'click', open );
$listItems.on( 'click', function( event ) { event.stopPropagation(); } );
}
function open( event ) {
if( current !== -1 ) {
$listItems.eq( current ).removeClass( 'cbp-hropen' );
}
var $item = $( event.currentTarget ).parent( 'li' ),
idx = $item.index();
if( current === idx ) {
$item.removeClass( 'cbp-hropen' );
current = -1;
}
else {
$item.addClass( 'cbp-hropen' );
current = idx;
$body.off( 'click' ).on( 'click', close );
}
return false;
}
function close( event ) {
$listItems.eq( current ).removeClass( 'cbp-hropen' );
current = -1;
}
return { init : init };
HTML:

Sorry if my English is not so good, but I really need to solve this.

Well I have no idea why would you do that, but if you want to reload the page every time you click on the Next and Prev buttons, including the Thumbnail you could do something like this:
$(document).ready(function() {
$('.es-nav span, .es-carousel img').on('click', function() {
location.reload();
});
});
This will reload the page when you click on the nav or an image in the thumbnail area.

javascript forEach - add addEventListener on all buttons

I'm not so skilled with javascript so I'm looking for a little help.
I'm using a script found on Codrops (3D Grid Effect - http://tympanus.net/Development/3DGridEffect/).
All is working fine as expected but I'm trying to "modify" it for my needs.
Basically, I want to trigger the "effect" NOT clicking on the whole container but on a button placed inside it.
The structure I'm using is:
<section class="grid3d vertical" id="grid3d">
<div class="grid-wrap">
<div class="grid">
<div class="box"><div class="btn-click-me">Click to Show</div></div>
<div class="box"><div class="btn-click-me">Click to Show</div></div>
<div class="box"><div class="btn-click-me">Click to Show</div></div>
</div>
</div>
<div class="content">
<div>
<div class="dummy-img"></div>
<p class="dummy-text">Some text</p>
<p class="dummy-text">Some more text</p>
</div>
<div>
<!-- ... -->
</div>
<!-- ... -->
<span class="loading"></span>
<span class="icon close-content"></span>
</div>
</section>
<script>
new grid3D( document.getElementById( 'grid3d' ) );
</script>
And the script (js) is

Now, I'm aware that the "crucial" portion of the code where I have to look is:
// open the content element when clicking on the main grid items
this.gridItems.forEach( function(item, idx ) {
item.addEventListener( 'click', function() {
item._showContent( idx ); } ); } );
So, my question again: how to trigger the event when the div (button) class "click-me" is clicked on every "boxes"?
Thanks to all in advance (i'm struggling with it for hours...)

Have a look at the example here,
http://jsfiddle.net/y0mbn94n/
I have added some intialisation to get your particular classes
// get grid buttons and then make an iterable array out of them
this.gridButtons = this.el.querySelectorAll('button.btn-click-me');
this.gridButtonItems = [].slice.call(this.gridButtons);
and changed the function which iterates and adds a listener.
// open the content element when clicking on the buttonsItems
this.gridButtonItems.forEach(function (item, idx) {
item.addEventListener('click', function () {
self._showContent(idx);
});
});

If you want to call a callback function when the user clicks on a button:
var buttons = document.querySelectorAll('.btn-click-me');
for (var i = 0; i < buttons.length; i++) {
var self = buttons[i];
self.addEventListener('click', function (event) {
// prevent browser's default action
event.preventDefault();
// call your awesome function here
MyAwesomeFunction(this); // 'this' refers to the current button on for loop
}, false);
}

with the structure given
<div class="grid-wrap">
<div class="grid">
<div class="box"><div class="btn-click-me">Click to Show</div></div>
<div class="box"><div class="btn-click-me">Click to Show</div></div>
<div class="box"><div class="btn-click-me">Click to Show</div></div>
</div>
</div>
you just have to change the line you've said to:
item.children[0].addEventListener( 'click', function() {
as the btn-click-me would be the first child of each item.
If you would like a more generic solution you could use:
item.getElementsByClassName('btn-click-me')[0].addEventListener( 'click', function() {
where bnt-click-me would be the class of the button that you would want to bind the click event. Notice that [0] so you can select the very first item of the array, as getElementsByClassName will return one, even if there's only one element.
But if you say you're just starting with javascript y really recommend you using jQuery, it's selectors are much easier than vanilla javascript.

URL Renaming via JavaScript

I’m developing a website based on this tutorial and would like to rename the URLs from /?chapter=# to their respective navigation names, e.g. /work, /about, /services etc.
index.php:
<aside id="menu">
<div id="scroll">
<nav>
<ul>
<li>Work</li>
<li>About</li>
<li>Services</li>
<li>Blog <!-- Coming Soon... --> </li>
<li>Contact</li>
</ul>
</nav>
</div> <!-- #scroll -->
</aside> <!-- #menu -->
...
...
<div class="content-scroller">
<div class="content-wrapper">
<article class="content" id="introduction">
<div class="inner">
...
...
<article class="content" id="chapter1">
<div class="inner">
...
...
jquery.page.js:
(function(window, undefined) {
var Page = (function() {
var $container = $( '#container' ),
// the scroll container that wraps the articles
$scroller = $container.find( 'div.content-scroller' ),
$menu = $container.find( 'aside' ),
// menu links
$links = $menu.find( 'a' ),
$articles = $container.find( 'div.content-wrapper > article' ),
// button to scroll to the top of the chapter
// only shown when screen size < 960
$toTop = $container.find( 'a.totop-link' ),
// the browser nhistory object
History = window.History,
// animation options
animation = { speed : 800, easing : 'easeInOutExpo' },
// jScrollPane options
scrollOptions = { verticalGutter : 0, hideFocus : true },
// init function
init = function() {
// initialize the jScrollPane on both the menu and articles
_initCustomScroll();
// initialize some events
_initEvents();
// sets some css properties
_layout();
// jumps to the respective chapter

_goto();
},
_initCustomScroll = function() {
// Only add custom scroll to articles if screen size > 960.

// get the url from history state (e.g. chapter=3) and extract the chapter number
var chapter = chapter || History.getState().url.queryStringToJSON().chapter,
isHome = ( chapter === undefined ),
// we will jump to the introduction chapter if theres no chapter

// left / top of the element
var left = $article.position().left,
top = $article.position().top,
// check if we are scrolling down or left
// is_v will be true when the screen size < 960
is_v = ( $(document).height() - $(window).height() > 0 ),

// otherwise the scroller (div.content-scroller) will animate the scrollLeft
param = ( is_v ) ? { scrollTop : (isHome) ? top : top + $menu.outerHeight( true ) } : { scrollLeft : left },
$elScroller = ( is_v ) ? $( 'html, body' ) : $scroller;
$elScroller.stop().animate( param, animation.speed, animation.easing, function() {
// active class for selected chapter
$articles.removeClass( 'content-active' );
$article.addClass( 'content-active' );
} );
}
},
_saveState = function( chapter ) {
// adds a new state to the history object
// this will trigger the statechange on the window

_initWindowEvents = function() {
$(window).on({

$('article.content').each( function() {
var $article = $(this),
aJSP = $article.data( 'jsp' );

// return false;
});
};
return { init : init };
})();
Page.init();
})(window);
How would I be able to do this?
Thanks

Well, this line is what's writing your history state:
History.pushState(null, null, '?chapter=' + chapter);
So you would need to modify that function to do what you want. If you have a small site then you could make conditionals to swap the state to whatever you want easily. If you have a large dynamic site you don't want to do this unless you love horrible, tedious maintenance...
_saveState = function(chapter) {
// adds a new state to the history object
// this will trigger the statechange on the window
if (History.getState().url.queryStringToJSON().chapter !== chapter) {
var page;
if(chapter == 1)
page = "/about";
else if(chapter == 2)
page = "/services";
else
page = '?chapter=' + chapter;
History.pushState(null, null, page);
}
},
I may have missed the point of your question though. If so I can update this answer
