Trying to filter non-hovered elements with jquery

I have an image gallery. Basically I am trying to go for something that lets the hovered image maintain its styling properties but the background (non-hovered images, I should say) filter to grayscale.
This is my first project and I am trying to push myself. I am making some mistakes but learning from each one. Your help is appreciated.
HTML:
<section id="image-gallery">
<div class="container">
<div id="imageboxing" class="disciplines">
<img src="images/martial-arts-banner/boxing.png">
<div class="imagetext">
<h3>BOXING</h3>
</div>
</div>
<div id="imagekb" class="disciplines">
<img src="images/martial-arts-banner/kickboxing.png">
<div class="imagetext">
<h3>KICKBOXING</h3>
</div>
</div>
<div id="muaythai" class="disciplines">
<img src="images/martial-arts-banner/muaythai.png">
<div class="imagetext">
<h3>MUAYTHAI</h3>
</div>
</div>
<div id="wrestling" class="disciplines">
<img src="images/martial-arts-banner/wrestling.png">
<div class="imagetext">
<h3>WRESTLING</h3>
</div>
</div>
<div class="clear"></div>
</div>
</section>
JQUERY:
$(document).ready(function() {
$(".disciplines img").hover(function(){
var images = $(".disciplines img");
$(this).toggleClass("active-image");
$(this).css("cursor", "pointer");
$(this).next().find('h3').slideToggle();
if (images.not(".active-image") {
$(images).css("filter", blur("20px"));
}
});

You have to do it like below:-
$(document).ready(function() {
$("#image-gallery img").hover(function(){ // on hover of image
$(this).toggleClass("active-image");
$(this).css("cursor", "pointer");
$(this).parent().css({"filter": ""}); //remove it's parent filter css
$('img').not($(this)).parent().css({"filter":'blur(5px)'}); //add filter css to all othe images parent-div apart from thr current clicked-one
}, function () { //when hover-out
$('.disciplines').css({"filter": ""}); //remove filter css from all div
});
});

Hide parent div class if child div class does not have content when there are multiple parent divs with the same class name

I have a slider where some of the images in the slider can have an optional photo- credit containing text or link in a popper. I would like to iterate over all of the popper instances and if all of the p tags in the .photo-credit p class are empty, then hide only that instance of the parent popper. I've tried to piece together a solution from some other posts, but have not been able to get it to work. The code I have does not hide a popper if all p tags are empty for that popper. I'm a JavaScript newbie and would appreciate any help.

JavaScript
$('.popper').each(function () {
//var $thisPopper = $(this);
var hasContent = 0;
$('.photo-credit p').each(function () {
if($(this).html().length > 0) {
hasContent++;
}
});
if(hasContent > 0){
//$thisPopper.hide();
$(this).hide();
}
});

You were on the right direction. However a couple mistakes in your javascript.
You tried to target all the div with "popper" class. However, the div with "popper" and "photo-credit" are on the same level. Why not targeting their parent div instead?
Try this code. It's been tested (Link to jsfiddle)
$('.slider-item').each(function () {
var thisSilerItem = $(this);
var hasContent = 0;
thisSilerItem.find('.photo-credit p').each(function () {
if($(this).html().length > 0) {
hasContent++;
}
});
if(hasContent <= 0){
thisSilerItem.find('.popper').hide();
}
});
Edit:
Bonus:
If your page has a large amount of sliders, this jquery solution will cause some UX issues ("jumpy" div on/after page load)
Try a CSS only solution.
When you render your DOM elements. Add a class to "popper" div if the content of "photo-credit" is empty.
<div class="popper hide">
// img
</div>
Then in your CSS, add
.popper.hide { display: none; }

It's hard to fully gather what you want to do, but if I understand correctly...
$('.popper').each(function () {
var photoCredit = $(this).find(".photo-credit p")
if ( $(photoCredit).is(':empty') ){
$(this).hide();
}
});
It's worth pointing out that CSS4 developers are working on a 'has' selector but as of July 2017 there is no support for any browser just yet.
It is expected to work in the following manner:
.popper:has(> p:empty) { display: none }
I hope this helps... :)

You can check this code.
$.each($('.popper'), function (index, popper) {
var isEmptry = true;
$.each($(popper).next('.photo-credit').children(), function (index, ptag) {
if ($.trim($(ptag).html()) != '')
isEmptry = false;
});
if (isEmptry)
$(popper).hide();
});
Working code
$.each($('.popper'), function (index, popper) {
var isEmptry = true;
$.each($(popper).next('.photo-credit').children(), function (index, ptag) {
if ($.trim($(ptag).html()) != '')
isEmptry = false;
});
if (isEmptry)
$(popper).hide();
});

Simulate button click with delay

I have a function that switches between 3 divs when one of 3 buttons is clicked (each button is linked to each div). But I also need that function to click each button automatically with 4 seconds delay. I want to achieve something like a slider that switches between those 3 divs automatically but the divs can also be switched by buttons. Is it possible to do? If so, how to do that? I'm a total jQuery / javascript beginner and I have no idea how to make it work.
Code attached below.
$(document).ready(function() {
$('#button_slide1').trigger('click');
$('.btn a').on('click', function(e) {
e.preventDefault();
//figure out which slide to show
var slideToShow = $(this).attr('rel');
//hide current slide
$('#header .slides.active').removeClass('active')
$('#' + slideToShow).addClass('active');
//show new slide
});
});
.slides:not(.active) {
display: none;
}
.btn {
float: left;
margin: 5px;
}
.btn p {
padding: 0;
margin: 0;
text-align: center;
}

You need to set an interval using javascript:
var inx=0, // the button index that must be clicked
totalButtons = $('.buttons-wrapper').find('div.btn').length; // total number of buttons
var myInterval = setInterval(clickButton, 4000); // name of the function that needs to be triggered, time interval in miliseconds
function clickButton() {
if (inx >= totalButtons) // check for out of index
inx = 0;
$('.buttons-wrapper').find('.btn').eq(inx).find('a').first().trigger('click');
inx=inx+1; // adding one unit to the index
}

Use
$('.someParentClass')('.someClass').slice(-5).remove();
to remove last 5 divs of class someClass inside some someParentClass', and if$abc` is the html you want to add on the top use
$(".someParentClass").prepend($abc) or
$(".someParentClass").html($abc+$(".someParentClass").html())

Adding descriptions inside a blueimp gallery

I am using a BlueImp Gallery to add lightboxes to my image gallery. So, when you click on an image thumbnail, it launches a lightbox with a larger version of the image etc.
I also want to add in some descriptive text and a button to each slide of the lightbox, but I am having trouble making it work. It won't show the placeholder descriptions that I have added in.
Here's what I have so far;
HTML:
<div id="blueimp-gallery" class="blueimp-gallery">
<!-- The container for the modal slides -->
<div class="slides"></div>
<!-- Controls for the borderless lightbox -->
<h3 class="title"></h3>

CSS:
.blueimp-gallery > .description {
position: absolute;
top: 30px;
left: 15px;
color: red;
display: none;
}
.blueimp-gallery-controls > .description {
display: block;
}
JS:
blueimp.Gallery(
document.getElementById('links'),
{
onslide: function (index, slide) {
var text = this.list[index].getAttribute('data-description'),
node = this.container.find('.description');
node.empty();
if (text) {
node[0].appendChild(document.createTextNode(text));
}
}
}
);
And in my body (gallery.js is the file where I've added the above JS):
<script src="//code.jquery.com/jquery.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="lib/fancybox/jquery.fancybox.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="http://blueimp.github.io/Gallery/js/jquery.blueimp-gallery.min.js"></script>
<script src="js/bootstrap-image-gallery.min.js"></script>
<script src="js/gallery.js"></script>
Any pointers on where I've gone wrong would be much appreciated!

You can pass any needed data on a element, and then display it in the gallery.
I spend a lot of time trying to find an answer, so I'll leave it here.
Here is an example:
HTML:
<div id="blueimp-gallery" class="blueimp-gallery">
<div class="slides"></div>
<h3 class="title"></h3>
<p class="description"></p>
<p class="example"></p>
...
</div>
------
<div id="links">
Banana
Apple
</div>
JS:
document.getElementById('links').onclick = function (event) {
event = event || window.event;
var target = event.target || event.srcElement,
link = target.src ? target.parentNode : target,
options = {
index: link, event: event,
onslide: function (index, slide) {
self = this;
var initializeAdditional = function (index, data, klass, self) {
var text = self.list[index].getAttribute(data),
node = self.container.find(klass);
node.empty();
if (text) {
node[0].appendChild(document.createTextNode(text));
}
};
initializeAdditional(index, 'data-description', '.description', self);
initializeAdditional(index, 'data-example', '.example', self);
}
},
links = this.getElementsByTagName('a');
blueimp.Gallery(links, options);
};
CSS:
You can use .scss to refactor it, but it's just for example
.blueimp-gallery > .description, .blueimp-gallery > .example {
position: absolute;
top: 30px;
left: 15px;
color: #fff;
display: none;
}
.blueimp-gallery-controls > .description, .blueimp-gallery-controls > .example {
display: block;
}

Sorry if to late but I find a way to do this, only change the JS from:
blueimp.Gallery(
document.getElementById('links'),
{
onslide: function (index, slide) {
var text = this.list[index].getAttribute('data-description'),
node = this.container.find('.description');
node.empty();
if (text) {
node[0].appendChild(document.createTextNode(text));
}
}
}
);
to this:
blueimp.Gallery(
document.getElementById('links'),
{
onslide: function (index, slide) {
var text = this.list[index].getAttribute('data-description'),
node = this.container.find('.description');
node.empty();
if (text) {
node[0].innerHTML = text;
}
}
}
);

blueimp.Gallery(
document.getElementById('links'), {
onslide: function (index, slide) {
var text = this.list[index].getAttribute('data-description'),
node = this.container.find('.description');
node.empty();
if (text) {
node[0].appendChild(document.createTextNode(text));
}
}
});

Have a look at this one, it is a working one.
Just check what you've done wrong compared to mine.

use
document.getElementById('links').getElementsByTagName('a') or .children()

That works only for the first link...
I am trying to get it to work with html in the data-description. I have it working and pulling in the decsription text, but how do you parse the html to work as a link?

here it is working with FancyBox, http://jsfiddle.net/yShjB/2/
but I would much rather use the BlueImp Gallery..
