Image modals on multi-tab page

Image modals on multi-tab page - javascript

I want to create a multi-tabs page with an image modal on each tab.
I used code from w3school.com. The modal only shows on the first page but not in the others. No matter what image I click, the modal with that image will show only in the first page. I am new to web design, so I prefer to use CSS and simple JavaScript.
Can anybody help me figure out how to make the modal show on the correct page?
Edited on Oct 02, 2021, I revised my CSS and Javascript and fixed the issue using a loop. Just sharing for anyone might be interested in.
Revised JavaScript
///// Image display modals
// All page modals
var modals = document.querySelectorAll('.modal');
// Get the image and insert it inside the modal - use its "alt"
// text as a caption
var img = document.querySelectorAll("img.myImg")
var modalImg = document.querySelectorAll("img.modal-content")
var captionText = document.querySelectorAll(".modal-caption");
// Get the <span> element that closes the modal
var spans = document.getElementsByClassName("close");
// When the user clicks the image, open the modal
for (var i = 0; i < img.length; i++) {
img[i].onclick = function() {
for (var index in modals) {
modals[index].style.display = "block";
for (var index in modalImg) {
modalImg[index].src = this.src;};
for (var index in captionText) {
captionText[index].innerHTML = this.alt;}
}
}
}
// When the user clicks on <span> (x), close the modal
for (var i = 0; i < spans.length; i++) {
spans[i].onclick = function() {
for (var index in modals) {
if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
}
}
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target.classList.contains('modal')) {
for (var index in modals) {
if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
}
}
}

Separate function for each modal will work out now , further you can look into this and loops for small code in the near future

How to auto-click on button in the website that opened in new tab

Need your help below, all codes below are from "example.com" assuming:
Click Me
When I click on "Click Me", it will run the function "gp()" below
<script>
function gp(pul){
var qal = "vo";
var tul = document.querySelectorAll('[target="'+qal+pul+'"]');
[].slice.call(tul).forEach(
function(link){
setTimeout(function(){
if(pul == 1){
window.open("http://www.example.com",qal+pul);
}else
if(pul == 2){
window.open("http://www.example.com",qal+pul);
}
},1000);

The basic idea is, I am in the urlA, when I click on one link, it will load the same urlA in the new tab. In this new tab, when it load, I want it to auto-click on the button to trigger the pop out message.
Thanks in advance for your help.

What do you mean with auto click?
The new tab, does it open a site made by you?
You should use url params for that, I will make for you a very basic example, you have to improve this, if you want to have more functionality in it.
For html, you use:
<a target="_blank" href="http://example.com/index.html?clickButton=true">Link</a>
The parameter is added to the href link, clickbutton=true.
for the JS you simply write something like this:
function buttonClick() {
alert('pop up')
}
let url = window.location.href;
let params = url.split('?');
let myparam = params[1].split('=');
if (myparam[1] === 'true') buttonClick();
I just got the url string and used some split functions to get the result of the parameter.
There is for sure specific functions to do this in a better way, but I never used them, so I give you some basic JS code.

Modal Images With Image Description

Modal Images With Image Description
I found this code on here about making multiple Modal Images.
However I cannot seem to find the best way to add the description text along with it when I open the modal up. I have been following the code on the 2nd to last answer on this post:
Several Modal Images on page
which was helping me a lot but I need description text not caption text.
If anyone is willing to help me solve this it would be much appreciated.
Thank you in Advance!

You need to wrap img + text with div so after click on wrapped div then pick inside content by .innerHTML property and change modal img to div.
Just small modification into your js code modalImg.src = this.src to modalImg.innerHTML = this.innerHTML; something like below snippet.
I hope below snippet will help you lot.
var modal = document.getElementById('myModal');
// to all images -- note I'm using a class!
var images = document.getElementsByClassName('myImg');
// the image in the modal
var modalImg = document.getElementById("img01");
// and the caption in the modal
var captionText = document.getElementsByClassName("text");
// Go through all of the images with our custom class
for (var i = 0; i < images.length; i++) {
var img = images[i];
// and attach our click listener for this image.
img.onclick = function(evt) {
modal.style.display = "block";
// modalImg.src = this.src;
modalImg.innerHTML = this.innerHTML;
captionText.innerHTML = this.alt;
}
}

It would be far more simple to place image and text in the same container.
<div class="image-container">
<img class="myImg" src="http://onebigphoto.com/uploads/2012/10/midnight-sun-in-lofoten-norway.jpg" alt="Midnight sun in Lofoten, Norway" width="300" height="200">
<div class="text">The Beautiful mountain over the Norway River was a spectacular view to see..</div>
</div>
Then use JavaScript to declare a variable called modalContent and select your container.
var modalContent = getElementById('image-container');
It just simplifies everything and reduces the number of selectors required. Looking at your code I was having trouble trying to understand if each image displayed in a modal window separately or all together. I hope that this has helped.

How to make JS/Jquery perspective effect work inside modal?

How can I get this effect below to happen inside the modal? I have tried a bunch of methods and it seems like I am missing something. When I put all of the content in the .wrap div inside the "MODAL CONTENT" div it no longer shows anywhere. Then when I correct the css to target the modal properly #myModal modal-content .wrap {... the content just shows up as images next to each other.. I'm completely lost as to why that is happening? Can someone explain how I can make this work inside the modal pls?

My guess is that the content is showing up in the modal, but it's getting cropped. Try adding a specific height to .wrap or .modal-content (note 100% won't work because the parent and the absolutely positioned children have no height).
.wrap {
background-color: #0F2044;
-webkit-perspective: 100px;
perspective: 100px;
position: relative;
overflow: hidden;
// Add something like this
height: 50vh;
}
Also, if you were trying to target it with #myModal modal-content .wrap {..., as you said above, you're missing a class selector (.) before modal-content. Should be #myModal .modal-content .wrap {...

modal image based on radio selet as array index

I have this very close but not quite. What I am looking for is to cycle images based on a radio button selection, this works fine. I would also like a modal on click of the image, so if I select radio selection 1, image name from the array shows and is clickable to a modal, similarly for each other radio option. Again, this is working fine. what is not is the modal pop up based on the radio button image.
Here is the css used:
#piGal ul {
float: left;
list-style-type: none;
padding: 20px 2em 3em 2em;
}
#piGal img {
max-width: 100%;
height: auto;
padding: .5em .5em 2em .5em;
}
#piGal .outer {

}

The radio button (simplified) is as follows:
<div class="contentText">
<section>
<h5>Choose color</h5>
<ul id="radio-attribute" class="radio-attribute">
<li class="radio-attribute">
<label for="1" class="radio-attribute">
<input type="radio" id="1" name="id[27]" value="170" onClick="change_image(this.id)">
<img src="images/silver_swatch.png" alt="GBM0911S Silver" title=" GBM0911S Silver " width="42" height="40" />
</label>
</li>
<li class="radio-attribute">
<label for="2" class="radio-attribute">
<input type="radio" id="2" name="id[27]" value="175" onClick="change_image(this.id)">
<img src="images/blue_swatch.png" alt="GBM0911B Blue" title=" GBM0911B Blue " width="45" height="40" />
</label>
</li>
</ul>
</section>
</div>
And the javascript is as follows:
<script type="text/javascript">
<!--
var images = ["GLAMOURFRONT.jpg","GBM0911S.png"];
function preload(arrayOfImages) {
$(arrayOfImages).each(function () {
$('<img />').attr('src',this).appendTo('body').css('display','none');
});
}
preload(images);
var galleryImage = document.querySelector("#piGalImg")
var modal = document.getElementById('myModal');
var img = document.getElementById('piGal');
var modalImg = document.getElementById("piGal");
var captionText = document.getElementById("caption");
function change_image(radioID) {
var imageID = radioID;
document.getElementById("piGal").innerHTML = "<img id=\"myImg\" src=\"images/"+ images[radioID] +"\" />";
}
// Get the modal
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
document.getElementById("piGal").onclick = function(){
modal.style.display = "block";
modalImg.src = "<img id=\"piGal\" src=\"images/"+ images[imageID] +"\" />";
captionText.innerHTML = this.alt;
}
document.querySelectorAll('label.radio-attribute img').forEach(function (radioClick) {
radioClick.addEventListener("click", function () {
// modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
});
});
//-->
</script>
The image rotates based on the radio selection without issue, the modal though shows the radio image name verses the image from the image array position. I use the radio ID to determine the array element (image name) to use for the modal pop up, it is this part that is not working well.
https://jsfiddle.net/8c09e9j0/

You have multiple elements on the page with the same id="piGal", so modalImg.src is trying to set the src on the first element with an id of pieGal, which is not the image element in your modal. id's must be unique. Change your modal ID to something unique to ensure you're trying to modify the correct element.
<img class="modal-content" id="piGalImg">
var modalImg = document.getElementById("piGalImg");
If your images are stored in an array store the index in a data-attribute on the image with the event listener and access the image array directly:
HTML:
<img src="https://placebear.com/10/20" data-arrayid="0" alt="GBM0911B Blue" title=" GBM0911B Blue " width="45" height="40" />
JS:
images = [
'400/400.jpg',
'400/500.jpg'
]
modalImg.src = 'https://placebear.com/' + images[this.dataset.arrayid];

Convert Javascript value into a link?

How am I able to convert the user input into a clickable link within the modal? (user entries will be in a URL format e.g. www.bbc.co.uk). The code I have used is purely from w3c schools and am experimenting how modules could be optimized.
I have added the code below.
<br><b>URL</b> <input type="text" size="40" value="" name="url" id="url" class="form-control" title="Enter the URL of a web page" onchange="displayURL()">
<br><br><br><br><br>

Thanks

It is actually very simple, you have to put the data read from the input box into an anchor tag:
<br><b>URL</b> <input type="text" size="40" value="" name="url" id="url" class="form-control" title="Enter the URL of a web page" onchange="displayURL()">
<br><br><br><br><br>
<style>
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
font-family: foco;
}
/* Modal Content */
.modal-content {
position: relative;
background-color: white;
margin: auto;

The important part is:
var readValue=document.getElementById("url").value;
document.getElementById("skkr").innerHTML = ''+readValue+'';

W3 Schools has a nice little demo for just this thing.
<!DOCTYPE html>
<html>
<body>
<p>Click the button to display a string as a hyperlink.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var str = "Free Web Building Tutorials!";
var result = str.link("https://www.w3schools.com");
document.getElementById("demo").innerHTML = result;
}
</script>
</body>
</html>
https://www.w3schools.com/jsref/jsref_link.asp for reference will guide you further.
Hopefully you can figure out how to target your element to update with your user input from the example provided.

You have two elements with the id 'skkr'. That's wrong.
Remove the id 'skkr' from this line <p id="skkr"></p>
Next, update the function displayURL() like so:
var link = document.getElementById("skkr");
var url = document.getElementById("url").value;
link.setAttribute("href",url);
link.innerHTML = url;
