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 ?
HTML :
<div class="animal_card">
<div class="card_title">
<h3>title</h3>
</div>
<div class="card_image">
<img src="image.img" alt="">
</div>
<div class="card_text">
<div class="card_info">
<div class="card_info_age">
<h4>Age</h4>
<p>14</p>
</div>
<div class="card_info_gender">
<h4>Gender :</h4>
<p>Female</p>
</div>
</div>
<h4>Who am I</h4>
<p>Description Text</p>
</div>

let i;
let keyMap = {};
for (i = 0; i < modal.length; i++) {
const item = modal[i];
const key = item.getAttribute('key');
keyMap[key] = item;
}
return keyMap;
}
return null;
};
const modalMap = getKeyMap(modal);
const onCardClick = async (e) => {
const card = e.currentTarget && e.currentTarget.getAttribute('key') || null;
const selectedModal = modalMap[card] || null;
if (selectedModal) {
selectedModal.style.position = 'absolute';
}
}
cards.forEach(card => card.addEventListener('click', onCardClick));

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.

document.getElementById(`${quad}`).innerHTML = document.getElementById(`${quad}`).innerHTML + `<a class="thumbnail" href="${elemLoc[i]}"><img src="${elemLoc[i]}" width="350px" height="250px" border="0" /><span><img src="${elemLoc[i]}" width="900" height="700" /><br /></span></a> <br />`;
}
};
When going to the tab Extension/East/DSEX my innerhtml code works perfectly, but if I try the hsex tab the inner html in loadElementaries fails. Does anyone have any idea what's going on. Maybe the way the DOM is loading between tabs?
document.getElementById(`${quad}`).innerHTML works for dsex tab but not hsex...
I'm at work so I'm limited to using client side JS/HTML/CSS so nodejs isn't an option unfortunately.

output.children[i].style.display = 'none';
images.children[i].style.display = 'none';

i = Number(this.value) - 1;
output.children[i].style.display = 'block';
images.children[i].style.display = 'block';
});
});
</script>
My main requirement if the slider is in the first that phrase and image should be stored in local storage like that if it is in second that details should store.

There is no enough details about what json you want to store in the localStorage so that's why i am giving you the basic idea of how you can store a json in localStorage.
Basically you can't store json in localStorage directly but you can store that json in form of a stringand then converting that string(json) into json. Here is the basic example :
// setting json to localStorage
var jsonToBeStoredInLocalStorae = {
sliderImages = [
{path : 'image-path-here'},
{path : 'image-path-here'}
],
phrase : 'your image phrase'
};
localStorage.setItem('slider_json',JSON.stringify(jsonToBeStoredInLocalStorae ));
When you want to get that json from localStorage so you will do like this
//Here you are getting that json in `string` form from `localStorage` and parsing it to `json`
var localStorageJson = JSON.parse(localStorage.getItem('slider_json'));

In localStorage you can only save text strings, so if you want to save it is only one value per record, you insert a name and value to localStorage, but if you want to save an object, you must transform it to a text string with the function JSON.stringify

JS OnMouseOver-Event (DIV2) change BackgroundImage (DIV1)

Here comes the js:
<script type="text/javascript">
document.getElementsByClassName("fullscreen-column-1").onmouseover = function() {
document.getElementById("background-change").style.backgroundImage = "url('https://mywebsite.de/uploads/image-1.jpg')";
};
</script>
any one got the solution? I cant get it to work, i feel dumb right now...
Solution: posted by: Rajan Patil
for (i = 0; i < document.getElementsByClassName("fullscreen-column-1").length; i++) {
document.getElementsByClassName("fullscreen-column-1")[i].onmouseover = function() {
document.getElementById("background-change").style.backgroundImage = "url('your-image-url')";
}
}

You do not need JavaScript for this. Use CSS instead.
.fullscreen-column-1 {
width: 400px;
height: 1000px;
background-image: url(https://picsum.photos/400/1000);
transition: 0.2s ease-in-out;
}
.fullscreen-column-1:hover {
background-image: url(https://picsum.photos/400/1002)
}
<div class="fullscreen-column-1"></div>

There is a typo. getElementsById should be getElementById
Also attach your event listener this way :
for (i = 0; i < document.getElementsByClassName("fullscreen-column-1").length; i++) {
document.getElementsByClassName("fullscreen-column-1")[i].onmouseover = function() {
document.getElementById("background-change").style.backgroundImage = "url('your-image-url')";
}
}

Creating a star rating from an image based on a float number?

recently I have wanted to turn a number into a star rating and I stumbled upon this post here: https://stackoverflow.com/a/1987545/1871869 which is exactly what I wanted to do. I have followed this explanation but I can't seem to get it to work on my local environment, and I was wondering if someone could help me out. Here is my attempt:
$.fn.stars = function() {
return $(this).each(function() {
// Get the value
var val = parseFloat($(this).html());
// Make sure that the value is in 0 - 5 range, multiply to get width
var size = Math.max(0, (Math.min(5, val))) * 16;
// Create stars holder
var $span = $('<span />').width(size);
// Replace the numerical value with stars
$(this).html($span);
});
}
$(function() {
console.log("Calling stars()");
$('.results-contents span.stars').stars();
});
.results {
font-size: 0;
padding-bottom: 16px;
}
.results-content {
font-size: 13px;
display: inline-block;
margin-left: 20px;
vertical-align: top;
}
.results .results-content span.stars span.stars span {
background: url('/resources/graphics/stars-icons.png') 0 -36px repeat-x;
width: 175px;
height: 80px;
}
.results .results-content span.stars {
max-width: 80px;
background-position: 0 0;
}
<script type="text/template" id="results-template">
<div class="results">
<div class="results-content">
<span class="stars">4.0</span>
</div>
</div>
</script>
Image of stars:
What I wanted to do was to simply have the empty stars show, and then based on the rating, show the orange stars on top of the empty stars so that I can show full and half star ratings. However, all I get is a number to show up. My console.log above seems to be called but it seems like the actual rendering of the image and calculation of the star rating is not working. Any help would be appreciated. Thanks!

You had multiple issues from CSS styles being wrong to your selector being wrong. Below is not perfect, but it is rendering.
$.fn.stars = function() {
return this.each(function() {
// Get the value
var val = parseFloat($(this).html());
// Make sure that the value is in 0 - 5 range, multiply to get width
var size = Math.max(0, (Math.min(5, val))) * 36.5;
// Create stars holder
var $span = $('<span> </span>').width(size);
// Replace the numerical value with stars
$(this).empty().append($span);
});
}
$(function() {
console.log("Calling stars()");
$('.results-content span.stars').stars();
});
.results {
font-size: 0;
padding-bottom: 16px;
}
.results-content {
font-size: 13px;
display: inline-block;
margin-left: 20px;
vertical-align: top;
background: url('https://i.stack.imgur.com/rwkqF.png') 0 0 repeat-x;
width: 185px;
height: 35px;
}
.results .results-content span.stars span {
background: url('https://i.stack.imgur.com/rwkqF.png') 0 -36px repeat-x;
display: inline-block;
height: 35px;
