Modal Window on card click JS CSS PHP

So I have 6 cards on my html. Each one on click need to pop up a modal window (this modal window is the card with more informations, so each modal window is corresponding to one card).
I dont know how to do that. After a day searching on the web I'm here to ask your help.
I have tried to make the html animal_card, and my modal appart. Then all the content will change with php.
And the Javascript need to change the modal window css property to absolute on click.
Someone know how to do that with Javascript ?

<div class="animal_card">

So the direct answer using your example is modal on the onCardClick is returning a collection, not a single element. So selecting the first one modal[0] will fix the position update. I attached an example.
If you are going to show different modals based on the card you click on, you generally need to have a method to track them. Really depends on how you want to do that, based on ids, or index position or so on. Anyways, let me know if this helps.

Why does my slider go blank after reaching the end?

I'm having a two issues/problems with the following slide.
It is a "double slider", so, two simultaneous slider in body section.
First is that when i reach the last image (9-nth, cos that much both sliders contain), the second slider continues to work properly (sliding images infinitely) but the first one just get blank.
Or if i click on previous button on begining then second doesn't work and images disapear, while the first one work nicely. Can't figure it out why. I've tried changing the "id" in the HTML and styling it but nothing change.
Second is, that i finally need to make it more dynamic, so, to avoid hardcoding images in the HTML and to putt them in JS and somehow append them in the DOM, but don't know what exactlly to do; creating an array, or using the "createElement"?
And which logic could be usable to actually include them in the DOM and have the following slider(s), considering the provided code?
Since it's my just second slider which i'm making, i found it pretty much hard, so any help/hint/advice is welcomed.
P.S Must be in jQuery and plugins excluded, so please don't provide any plugins links.
Thank you in advance.
var slides = $('.slide');
slides.first().before(slides.last());
$('button').on('click', function() {
// Selecting the slides
slides = $('.slide');
// Selecting button
var button = $(this);
// Register active slide
var activeSlide = $('.active');
// Next function
if (button.attr('id') == 'next') {
slides.last().after(slides.first());
activeSlide.removeClass('active').next('.slide').addClass('active');
}
// Previous function
if (button.attr('id') == 'previous') {
slides.first().before(slides.last());
activeSlide.removeClass('active').prev('.slide').addClass('active');
}
});

Your code doesn't work properly because the slides = $('.slide') variable contains all slides from both sliders. You have to manipulate the slides in the to sliders independently. The second failure is that in your example the first slide is the initial active slide. Only slides in range second -> penultimate are allowed. Working example here
function handleSlide(slider, direction) {
var slides = $(slider).find('.slide');
if(slides.length < 1) return;
// Register active slide
var activeSlide = $(slider).find('.active');
// Next function
if (direction == 'next') {
slides.last().after(slides.first());
activeSlide.removeClass('active').next('.slide').addClass('active');
}
// Previous function
if (direction == 'previous') {
slides.first().before(slides.last());
activeSlide.removeClass('active').prev('.slide').addClass('active');
}
}
$('button').on('click', function() {
var button = $(this);
handleSlide($("#slider1"), $(button).attr('id'));
handleSlide($("#slider2"), $(button).attr('id'));
});

Loading images dinamically: You can do that by defining an array which contains the images and you can append the images into the slider using the jQuery 'append' method. Working example on jsFiddle.
function fillSliders(slider, images) {
$(slider).empty();
for(var i = 0; i < images.length; i++) {
if(typeof images[i] == "string" && images[i] !== "") {
var active = (i == 1) ? " active" : "";
$(slider).append('<div class="slide'+active+'"><img src="'+images[i]+'"
alt="image-'+i+'" /></div>');
}
}
}
var images = ["image1.jpg", "image2.jpg","image3.jpg","image4.jpg"];
fillSliders($("#slider"), images);

Bootstrap 4 - scrollSpy not updating nav links

I am trying to implement Bootstrap 4 scrollSpy feature on my site. I have given the body position relative:
body {
overflow-x: hidden;
position: relative;
}
And I have made nav-links underneath the navbar:
<div class="container-fluid page-nav">
<div class="container">
<div class="row">
<div class="col-md-9 offset-md-3">
<nav id="page-nav" class="nav section-links">
<a class="nav-link" href="#info">Info</a>
<a class="nav-link" href="#videos">Videos</a>
<a class="nav-link" href="#stats">Statistics</a>
</nav>
</div>
</div>
</div>
</div>
I am making the nav links fixed once I scroll to them:
$('body').scrollspy({ target: '#page-nav' });
let pageNav = document.querySelector('.page-nav');
let fixClass = 'is-fixed';
function stickyScroll() {
if( window.pageYOffset > 56 ) {
pageNav.classList.add(fixClass);
}
if( window.pageYOffset < 56 ) {
pageNav.classList.remove(fixClass);
}
}
$(window).scroll(stickyScroll);
I add the is-fixed class to make them fixed:
.is-fixed {
position: fixed;
left: 0;
right: 0;
z-index: 10;
top: 0;
}
But, scrollSpy is not working, what am I doing wrong and how can I fix this?

jquery number count to a target number and pop display on click

I have a website : my website
i have built a jQuery counter to count up to a target number for the points in the team.Plz click on team tab.
problem :
when I load the page,the jquery point count works fine.Lets say when you go to team section and refresh the page.But when I scroll to through the various sections and reach team section,the effect doesnot show up.It looks like normal numbers.Can it be made possible,when the user scrolls to the "team" section the number count with the effect shows up.
The code for that part :
(function ($) {
$.fn.countTo = function (options) {
options = options || {};
return $(this).each(function () {
// set options for current element
var settings = $.extend({}, $.fn.countTo.defaults, {
from: $(this).data('from'),
to: $(this).data('to'),
speed: $(this).data('speed'),
refreshInterval: $(this).data('refresh-interval'),
decimals: $(this).data('decimals')
}, options);
// how many times to update the value, and how much to increment the value on each update
var loops = Math.ceil(settings.speed / settings.refreshInterval),
increment = (settings.to - settings.from) / loops;
// references & variables that will change with each update
var self = this,
$self = $(this),
loopCount = 0,
value = settings.from,
data = $self.data('countTo') || {};
$self.data('countTo', data);
// if an existing interval can be found, clear it first
if (data.interval) {
clearInterval(data.interval);
}
data.interval = setInterval(updateTimer, settings.refreshInterval);
// initialize the element with the starting value
render(value);
function updateTimer() {
value += increment;
loopCount++;
render(value);
if (typeof(settings.onUpdate) == 'function') {
settings.onUpdate.call(self, value);
}
if (loopCount >= loops) {
// remove the interval
$self.removeData('countTo');
clearInterval(data.interval);
value = settings.to;
if (typeof(settings.onComplete) == 'function') {
settings.onComplete.call(self, value);
}
}
}
function render(value) {
var formattedValue = settings.formatter.call(self, value, settings);
$self.html(formattedValue);
}
});
};
$.fn.countTo.defaults = {
from: 0, // the number the element should start at
to: 0, // the number the element should end at
speed: 1000, // how long it should take to count between the target numbers
refreshInterval: 100, // how often the element should be updated
decimals: 0, // the number of decimal places to show
formatter: formatter, // handler for formatting the value before rendering
onUpdate: null, // callback method for every time the element is updated
onComplete: null // callback method for when the element finishes updating
};
function formatter(value, settings) {
return value.toFixed(settings.decimals);
}
}(jQuery));
jQuery(function ($) {
// custom formatting example
$('#count-number').data('countToOptions', {
formatter: function (value, options) {
return value.toFixed(options.decimals).replace(/\B(?=(?:\d{3})+(?!\d))/g, ',');
}
});
// start all the timers
$('.timer').each(count);
function count(options) {
var $this = $(this);
options = $.extend({}, options || {}, $this.data('countToOptions') || {});
$this.countTo(options);
}
});

problem 2:
I am trying to make a pop-up such that when the user clicks at the points box,where the number box is,the popup is displayed.Right now it appears at the bottom of the points box.
javascript for the popup .The html is in the above codes :
< script type = "text/javascript" >
$(document).ready(function() {
$('.tab a').on('click', function(e) {
e.preventDefault();
var _this = $(this);
var block = _this.attr('href');
$(".tab").removeClass("active");
_this.parent().addClass("active");
$(".counter col_fourth").hide();
$(block).fadeIn();
});
/**
* Fade in the Popup
*/
$('.counter col_fourth').on('click', function() {
$('#popup').fadeIn();
});
}); < /script>
please help me if anyone out here can.

Adding navigation buttons below my slider

I created a fade slider with images, text and links. I'd like to add some navigation bullets below it to control the images.
like this :
http://www.parallaxslider.com/preview_images/skins/bullets_skin.jpg
Here is the slider code:
html
<div class="slides">
<div class="slidiv">
<a href="..." ><img src="..." >
<span> text1 </span></a>
</div>
<div class="slidiv">
<a href="..." ><img src="..." >
<span> text2 </span></a>
</div>
<div class="slidiv">
<a href="..." ><img src="..." >
<span> text3 </span></a>
</div>
<div class="slidiv">
<a href="..." ><img src="...">
<span> text4 </span></a>
</div>
</div>
CSS
.slides {
overflow:hidden;
top:0;
position:relative;
width:100%;
height:206px;
z-index:920;
border-bottom:white 6px solid;
}
.slides img {
position:absolute;
left:0;
top:0;
}
.slides span {
position: absolute;
right: 100px;
top: 160px;
color:white !important;
font-size:20px;
}
Javascript
<script type="text/javascript">
$(function() {
$('.slides .slidiv:gt(0)').hide();
setInterval(function () {
$('.slides').children().eq(0).fadeOut(2000)
.next('.slidiv')
.fadeIn(2000)
.end()
.appendTo('.slides');
}, 6000); // 6 seconds
});
</script>

You have to define a unique id for each slide, then build html for circles (make sure you have a way of referencing which circle matches up to which slide). Then you capture the on click event, clear the interval, cycle forward until the slide in the "current" position matches the circle, then create the interval again. And of course every time it cycles forward you need to set a visual cue for the circle associated with the active slide.

EDIT:
This answer is not very good because it does not very well explain how it works, but this falls into "I could write a novel" explaining all of the different methods of doing what the OP has asked and how each method works. If someone else wanted to come along and offer better explanations of how this code works, I would approve.
