Crossfade a 6 images grid randomly, one by one

I've been trying since yesterday to do something a bit tricky (I guess).
I'm trying to do exactly what happens here: https://tympanus.net/Development/AnimatedResponsiveImageGrid/index2.html but this script is 8 years old and can't work with newer jQuery, anyway I wanted to redo it by myself.
What I need (well, what the marketing want me to do):
Having a 6 images grid which randomly crossfade to another image, but one by one. They should never repeat themselves.
So far I've done this, but all the crossfade are made 6 by 6. I want to do it, one by one, in a random order.

Can someone help me with this please?

You can select a cell col-4 at random, then apply the logic to only the 2x img in that cell.
Without changing too much of your existing code, change to:
var cells = $(".galery .col-4");
var randomId = (Math.floor(Math.random() * cells.length));
var cell = cells.eq(randomId);
cell.find("img:hidden").each(function(index) {
$(this).attr("src", result[index]);
});
cell.find("img").fadeToggle(1500);
Updated fiddle: https://jsfiddle.net/ju0comn2/1/
Due to the nature of Math.random() you will notice it runs the same images in the same order - seed the random. You'll also get the same image replacing with the same image.
For a rudimentary fix for duplicated images, check if any of the visible images have the same src as the new src:
var result = randomArray();
var cells = $(".galery .col-4");
var randomId = (Math.floor(Math.random() * cells.length));
var newsrc = result[0];
if ($(".galery img[src='" + newsrc + "']:visible").length > 0) {
changeSrc();
}
else {
var cell = cells.eq(randomId);
cell.find("img:hidden").each(function(index) {
$(this).attr("src", result[index]);
});
cell.find("img").fadeToggle(1500);
}
This could be handled with a while loop to keep getting randomIds, but as long as you have more images than panels, the recursive call is unlikely to stack overflow.

Javascript doesn't toggle the display of an element

So, I'm trying to obtain multiple slideshows on my website.
I have done almost everything, excepting the fact that when I press a picture, the modal of previews is showing, but the clicked image is not showing up. I have to use the buttons of the slideshow to go through them and make the first one to appear.
**
If you don't want to go along this whole code, here you can see what's happening: http://beta.eduardstefan.com
**
I am not trying to promote myself, I just think that I am not quite easy to understand without the example
So, my question, how can I make the first picture to show up when I press one, or why it's not happening, what is bad with my code?

function showSlides(){
var aux = slideIndex.length;
var i;
for(i=0; i<aux; i+=2) { slide(i,0); }
}
function slide(n,m){
var i;
var aux = document.getElementsByClassName("slideimg_" + n);
var aux2 = aux.length - 1;
if (slideIndex[n] == 3 && m == 1) slideIndex[n] = -1;
if (slideIndex[n] == 0 && m == -1) slideIndex[n] = 4;
slideIndex[n] += m;
if (slideIndex[n] < 0) slideIndex = aux2;
else if (slideIndex[n] > aux2) slideIndex = 0;

aux[slideIndex[n]].parentElement.style.display = 'block';
}
function closepreview(){
$('.imgpreview').css("display" , "none");
$('.slidepreview').css("display" , "none")
}
$(document).ready(function() {
$(".slide img").click(function(){
var id = $(this).attr('id');
var no = $(this).attr('data-no');
var no2 = no + 1;
$(".imgpreview").css("display" , "flex");
$(".no_" + no).css("display" , "flex");
$("img#" + id + ".slideimg_" + no2).css("display" , "block");
slideIndex[no2] = id;
});
}).resize();

The IDs must be unique.
Instead of inline event handlers I would suggest to attach them to the js code (separate html from js code).
I removed all IDs and I changed everything in jQuery using:
.index()
.toggle( display )
.nextAll(), .next(), .prev() and .prevAll()
I used a class: active. This class is used to mark the current active element. Moreover, every time I need to move next or prev I move this class to the corresponding element. This class takes track of which img must be shown.
The snippet:
$(document).ready(function() {
//
// Toggle visibility
//
$('.slide:not(.active), .slide:not(.active) img').toggle(false);
$('.slide.active, .slide.active img').toggle(true);
//
// closing preview....
//
$('.imgpreview .fa.fa-close').on('click', function(e) {
$('.imgpreview, .slidepreview').css("display" , "none");
//
// ...remove active class and toggle visibility
//
$('.imgpreview, .slidepreview').find('.active, .active img').toggleClass(false).removeClass('active');
});
//
// on prev....
//
$(".prev").on('click', function(e) {
//
// get the active element and so the previous one
//
var active = $(this).nextAll('.slide.active');
var prev = active.prev('.slide');
if (prev.length == 0) {
//
// if at the beginning take the last one
//
prev = $(this).nextAll('.slide').last();
}
//
// move active class and toggle visibility
//
active.removeClass('active');
prev.addClass('active').find('img').andSelf().toggle(true);
$('.slide:not(.active), .slide:not(.active) img').toggle(false);
});
$(".next").on('click', function(e) {
//
// get the active element and so the next one
//
var active = $(this).prevAll('.slide.active');
var next = active.next('.slide');
if (next.length == 0) {
//
// if at the end take the first one
//
next = $(this).prevAll('.slide').last();
}
//
// move active class and toggle visibility
//
active.removeClass('active');
next.addClass('active').find('img').andSelf().toggle(true);
$('.slide:not(.active), .slide:not(.active) img').toggle(false);
});
$(".slide img").on('click', function(e) {
//
// take the index of curr element in the parent element
//
var idx = $(this).closest('div.slide').index();
var no = $(this).data('no');
$('.imgpreview, .no_' + no).css('display' , 'flex');
$('.no_' + no).children().eq(idx).addClass('active');
$('.no_' + no).find('.slide:not(.active), .slide:not(.active) img').toggle(false);
$('.no_' + no).find('.slide.active, .slide.active img').toggle(true);
});
});

At least one problem is here:
var no = $(this).attr('data-no');
var no2 = no + 1;
no is a string so if no is "0", then no + 1 is "01", so instead you can do this:
var no = $(this).attr('data-no');
var no2 = Number(no) + 1;

Beyond that, why re-invent the wheel? There are plenty of good slideshow plugins available.

Javascript document.images.length returning 0

I am attempting to get all of the images with classname of tile into an array called tiles. I've tried a few things but it keeps giving me 0 length arrays/nodelists.
What am I doing wrong?
for(var i =0; i<document.images.length; i++){
var thumb = document.images[i]
if(thumb.className == "tile" && thumb.parentNode.tagName == "A")
tiles.push(thumb);
}
I have also tried
var allInputs = document.getElementsByTagName("img");
for(var i =0; i<allInputs.length; i++){
if(allInputs[i].className == "tile" tiles.push(allInputs[i]);
}

your script is fine, I just tested it. it probably returns 0 because you add the script to the top of you file, just make sure you add in the end:
<html>
<body>
<div id="board">
<img src="tile.jpg" class="tile" alt="" />
<img src="tile.jpg" class="tile" alt="" />
<img src="tile.jpg" class="tile" alt="" />
<img src="tile.jpg" class="tile" alt="" />
</div>
</body>
<script>
var tiles = [];
for(var i =0; i<document.images.length; i++){
var thumb = document.images[i]
if(thumb.className == "tile" && thumb.parentNode.tagName == "A")
tiles.push(thumb);
}
alert(tiles.length)
</script>
</html>
At least is the only cause I could find to return 0. Please let me know if it solved your issue.
If you ar importing the script from a different file, just add the import on the end, like this:
<html>
<body>
<div id="board">
<img src="tile.jpg" class="tile" alt="" />
<img src="tile.jpg" class="tile" alt="" />
<img src="tile.jpg" class="tile" alt="" />
<img src="tile.jpg" class="tile" alt="" />
</div>
</body>
<script src="myscript.js"></script>
</html>
a third option is to add your code in a function on document ready listener:
document.addEventListener("DOMContentLoaded", function(event) {
var tiles = [];
for(var i =0; i<document.images.length; i++){
var thumb = document.images[i]
if(thumb.className == "tile" && thumb.parentNode.tagName == "A")
tiles.push(thumb);
}
alert(tiles.length)
});

How can I hide one div before opening another?

How can I make it so that only one div can be shown at a time? I've tried adding "document.getElementById(currentID).style.display='none';" in the after the else but that doesn't work.
<h5 onclick="showImage('chair')">Chair</h5>
<h5 onclick="showImage('table')">Table</h5>
<h5 onclick="showImage('long_table')">Meeting Table</h5>
<div id="chair">
<img src="images/1.jpg" height="300px"/>
<h4>Product 1</h4>
</div>
<div id="table">
<img src="images/2.jpg" height="300px"/>
<h4>Product 2</h4>

Better to add a class to your HTML and then grab the divs by their class. You can then loop through the elements to hide them all and then un-hide the one you've clicked.
Example:
var arrProducts = document.getElementsByClassName('product');
for (i = 0; i < arrProducts.length; i++) {
arrProducts[i].style.display = 'none';
}
function showImage(id) {
for (i = 0; i < arrProducts.length; i++) {
if (id == arrProducts[i].id) {
if (document.getElementById(id).style.display === 'none') {
arrProducts[i].style.display = 'block';
} else {
arrProducts[i].style.display = 'none';
}
} else {
arrProducts[i].style.display = 'none';
}
}
}
h5 {
cursor: pointer;
}
.product img {
height: 10px;
width: 10px;
}
<h5 onclick="showImage('chair');">Chair</h5>
<h5 onclick="showImage('table');">Table</h5>
<h5 onclick="showImage('long_table');">Meeting Table</h5>
<div class="product" id="chair">
<img src="images/1.jpg" height="300px" />
<h4>Product 1 (Chair)</h4>
</div>
<div class="product" id="table">
<img src="images/2.jpg" height="300px" />
<h4>Product 2 (Table)</h4>
</div>
<div class="product" id="long_table">
<img src="images/3.jpg" height="300px" />
<h4>Product 3 (Meeting Table)</h4>
</div>

While this won't help you fix things in you current code, you can actually do this without any JavaScript by abusing radiobuttons. This is quite common.
http://jsfiddle.net/mo7yppp8/
Each div needs a radio button above it, and to be enclosed within a label. This way, clicking on the div will trigger the radiobutton, deselecting any other div in the process.
<label>
<input class="divSelector" type="radio" name="divSelector" value="" />
<div>Sample text</div>
</label>
Then, all you need is some CSS to hide the radiobuttons, and some to shrink the divs which aren't right after a checked input.
.divSelector {
display: none;
}
.divSelector:checked + div {
font-size: 12pt;
}
div {
font-size: 0pt;
background-color: blue;
color: white;
overflow: clip;
padding: 2em;
height: 12px;
}
div:hover {
background-color: grey;
}

Try substituting longtable for long_table at "Meeting Table" h5
var showImage = function showImage(id) {
var active = document.getElementById(id);
active.style.display = 'block';
var notActive = document.querySelectorAll("div:not(#" + active.id + ")");
Array.prototype.slice.call(notActive)
.forEach(function(el) {
el.style.display = "none";
})
};
div[id] {
display: none;
}
<h5 onclick="showImage('chair')">Chair</h5>
<h5 onclick="showImage('table')">Table</h5>
<h5 onclick="showImage('longtable')">Meeting Table</h5>
<div id="chair">
<img src="images/1.jpg" height="300px" alt="chair" />
<h4>Product 1</h4>
</div>
<div id="table">
<img src="images/2.jpg" height="300px" alt="table" />
<h4>Product 2</h4>
</div>
<div id="longtable">
<img src="images/3.jpg" height="300px" alt="meeting table" />
<h4>Product 3</h4>
</div>

You need to rethink the logic of your function, I'm guessing this is what you meant:
var currentID = "";
function showImage(id){
if(currentID != id){
if (currentID != "") // added this test in response to JFK's comment
document.getElementById(currentID).style.display='none';
document.getElementById(id).style.display='block';
currentID = id;
}
else { // added after OP clarified the question
document.getElementById(id).style.display='none';
currentID = "";
}
}

If you have the chance to use jQuery, there is a really awesome solution possible. It would work like this:
http://jsfiddle.net/dnf6gsuL/2/
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<h5>Chair</h5>
<div>
<img src="images/1.jpg" height="300px"/>
<h4>Product 1</h4>
</div>
<h5>Table</h5>
<div>
<img src="images/2.jpg" height="300px"/>
<h4>Product 2</h4>
</div>
<h5 id="longtable">Meeting Table</h5>
<div>
<img src="images/3.jpg" height="300px"/>
<h4>Product 3</h4>
</div>
<script>
$("h5").click(function(eve){
$("div").each(function(){
$(this).fadeOut("fast", function(){
$(eve.target).next("div").fadeIn("fast");
});
});
});
</script>

How do I make a direct call to a Menu item from the content?

I have this code, it works for a rotating menu that is obviously a ul> li> Menu.
What I would like to know is how to trigger (onClick, HRef, etc.) the function for a specific list item such as rot7.
I would like to click a line of text and fire the function, is this possible?
Example "Click here to go there" ,
Kinda like the old days -- {a href="some.html"}Click Here{/a} page loads.
In this case I want the text to open the 7th li> menu item using the form and function of the JQuery script.
There, clear as Mud.

EDIT:
The code above will not work because each time the menu is changing pages sets the container (.description) content with the original tags get upon initialization, so the page content including our a tag is overriden by a the original content which is same as previous one, but overrides the old one and that's why the click handler doesn't work - because it was set on an item which is overriden.
To not set the click handler each time when the menu changes the pages it should be bind into the link as simple as taht: <a onclick="$('#rotmenu li:nth-child(6)').click();" href="javascript:;">Book now to schedule your Complimentary Consultation</a>.
That's it - works fine.
