I'm trying to create a slider with html- vanilla javascript. I'm able to open a modal, show a wide slider image and small images (thumbnails). Everything looks fine but when I click the thumbnails (which have "small_image" class) they trigger events, change image and add the same images to the thumbnails section again.
I checked the console with console.log(e.target.className) when I clicked any of the thumbnails and it shows "slider" class not "small_image" class.. Why is this happening and how can I fix this ?
Html section
<div id="photos" class="tabcontent">
<div class="tabslider">
<div>
<img src="{{image_path("posts/5-1537128615.jpg")}}" class="slider">
</div>
<div>
<img src="{{image_path("posts/6-1537128615.jpg")}}" class="slider">
</div>
<div>
<img src="{{image_path("posts/7-1537128615.jpg")}}" class="slider">
</div>
<div>
<img src="{{image_path("posts/8-1537128615.jpg")}}" class="slider">
</div>
<div id="myModal" class="modal">
<span class="close cursor">×</span>
<div class="modal-content">
<!-- wide image -->
<div class="mySlides">
<img class="show_slider" src="">
</div>
<!-- small images -->
<div class="small_images"></div>
</div>
</div>
</div>
</div>
Javascript section
document.querySelector(".tabslider").addEventListener("click", function (e) {
if (e.target.className = "slider") {
let smallImages = document.querySelector(".small_images"),
images = document.querySelectorAll(".slider"),
slider = document.querySelector(".show_slider"),
sliderDiv = document.querySelector(".mySlides"),
model = document.querySelector("#myModal");
model.style.display = "block";
images.forEach(function (image) {
let img = Elementor.create("img", {"src": image.src, "class": "small_image"}),
div = Elementor.create("div", {"class": "columnlightbox"},);
div.appendChild(img);
smallImages.appendChild(div);
});
slider.setAttribute("src", e.target.src);
sliderDiv.style.display = "block";
}
})
e.target.className = "slider"
You are setting the value here, not comparing :D

I am using bootstrap 4.3.1 and would like to have a clickable icon in my list of thumbnails for a text.
I have a function where I click on the thumbnails and these images are displayed in large size next to them.
Now I want to have the same thing for my text.
Here is the code:
function myFunction(imgs) {
var expandImg = document.getElementById("expandedImg");
var imgText = document.getElementById("imgtext");
expandImg.src = imgs.src;
//imgText.innerHTML = imgs.alt;
expandImg.parentElement.style.display = "block";
}
<!--START Thumbnaill Navbar-->
<div style="overflow-y: auto; height: auto; width: 170px;">
<img src="../image" alt="###" class="img-thumbnail border-0 img-thumbnail-desktop" onclick="myFunction(this);">
<!--Here the icon for text -->
</div>
<!--END Thumbnaill Navbar-->
<!--Main Content-->
<div class="container expandedImgSize d-flex justify-content-center ">
<span onclick="this.parentElement.style.display='none'"></span>
<img class="img-fluid" id="expandedImg" src="../PlaceholderImage">
</div>
Is there a elegant solution to show just the text?
I'll try my best but i will probably need help from you guys ( 〃 ω〃)
Thanks you guys in advance!
I'm using angular 5 for displaying pages that have a lot of images with high res, and it takes too long to load.
What I want to do is to make a splash screen, a div that will cover the full screen, and after all the images finish loading it will disappear.
How and where do I implement this in angular 5?
window.onload = someFunction; // is not working well
page.component.html:
<div id="page" class="page">
<div id="splash"></div>
<div id="home-page">
<div class="container d-none d-lg-block">
<img src="assets/images/home/line_with_bird.png" alt="">
<div class="row">
<div class="col-3 ad-paper">
<img src="assets/images/home/paper.png" class="" alt="">
</div>
<div class="col-2">
<img id="arrow-word" src="assets/images/arrow_word.png" alt="">
<img id="ladder" src="assets/images/ladderLong.png" alt="">
</div>
<div class="col-6 offset-1 c2">
<div id="window"></div>
<div class="smicos">
<app-socialmedia style="width: 641px;"></app-socialmedia>
</div>
</div>
</div>
</div>
</div>
page.component.ts
ngOnInit() {
function splash() {
console.log('tttttttttttttttttttttttttttttttttttttttttt');
document.getElementById('splash').style.display = 'none';
document.getElementById('window').classList.add('window-animation');
}
window.onload = splash;
}
Do not hide your splash screen on ngOnInit. Instead do this:
Keep count of images you are showing in controller.
totalImages = 20;
Keep a load handler on each image;
<img (load)='checkAllLoaded()'>
In checkAllLoaded function, check if all images are loaded:
checkAllLoaded() {
this.totalImages = this.totalImages - 1;
if(this.totalImages === 0) {
document.getElementById('splash').style.display = 'none';
document.getElementById('window').classList.add('window-animation');
}
}
Set a div with *ngIf on a property which will turn to true only when the image is loaded.
<div class="splash" *ngIf="!loaded"></div>
<img [src]="img" (load)='loaded=true'>

I found two similar answers here but both were unsuccessful for my situation (given my limited ability to translate them to my situation). I have a page with a lot of fairly large images and the default method of Bootstrap is to load all the modal images upon page load. The visible html renders fairly quickly (I have a spinner for that) but the additional load time for the hidden modals makes the page impractical. I want the page to load only the visible (non-modal) content to complete the page load (and clear the spinner) and then load each modal's content only when that modal is fired. I've tried every lazyload solution I could find but the images will not render in the modal (the 'data-src' placeholders render but not the 'src' images that are supposed to replace them). I only want to lazyload (or load on 'show.bs.modal') the large images of the modal, those within the 'modal-body' class. I hope this is clear enough.
Sample code:
/* Javascript placed in the head */
<script>
function lazyLoad(){
var $images = $('.lazy_load');
$images.each(function(){
var $img = $(this),
src = $img.attr('data-src');
$img
.on('load',imgLoaded($img[0]))
.attr('src',src);
});
};
$('.modal-body').on("show.bs.modal", function () {
lazyLoad();
};
</script>
/* HTML in the modal section */
<div class="portfolio-modal modal fade" id="portfolioModal1" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-content">
<div class="galleryheader">
<img src="headerimage_1.png" height="77" width="1024">
</div>
<div class="close-modal" data-dismiss="modal">
<div class="lr">
<div class="rl">
</div>
</div>
</div>
<div class="container">
<div class="row">
<div>
<div class="modal-body lazy_load">
<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="images/largeimage_1A.jpg" height="585" width="800"class="img-centered" alt=""/>
</div>
<div class="modal-body lazy_load">
<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="images/largeimage_1A.jpg" height="585" width="800"class="img-centered" alt=""/>
</div>
<div class="modal-body lazy_load">
<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="images/largeimage_1A.jpg" height="585" width="800"class="img-centered" alt=""/>
</div>
</div>
</div>
</div>
<div class="close-lower" data-dismiss="modal">
<IMG SRC="images/close.jpg" WIDTH="85" HEIGHT="32"></a>
</div>
</div>
</div>
</div>
Firstly, put the lazy_load class on the img element, not on the parent div. Secondly the jQuery you need is something like this:
$('.portfolio-modal').on("show.bs.modal", function () {
$('.lazy_load').each(function(){
var img = $(this);
img.attr('src', img.data('src'));
});
});
Notes:
Use the portfolio-modal class to identify the modal.
Use the jQuery data() method to get the image to lazily load.
I'm trying to hide a visible section then show a hidden section using JQuery .hide() and .show(). When the event fires (on clicking an image) it only hides the visible section momentarily, then becomes visible again with the previously hidden section now visible below the first visible section. Based on the docs I've read and some tutorials I've watched this shouldn't be happening.
HTML:
<div class="transition-div">
<section class="project-section">
<div class="project-wrapper" id="project-one">
<div class="desc-text">
<h2>Header</h2>
</div>
<div class="project-image-wrapper">
<img class="project-image" id="project-img-one" src="images/img1.png">
<button class="project-button">Button
</button>
</div>
</div>
</section>
<section class="project-section hidden">
<div class="project-wrapper">
<div class="desc-text">
<h2>Header</h2>
<p>Some description text</p>
</div>
<div class="project-image-wrapper">
<img class="project-image" src="images/img1.png">
</div>
</div>
</section>
</div>
JS:
$('.hidden').hide();
var slideSection = function() {
$('.project-image-wrapper').click(function() {
var $parentDiv = $(this).parents('.transition-div');
var $childToShow = $parentDiv.find('.hidden');
var $childToHide = $childToShow.siblings('.project-section');
$childToHide.hide(300, hideActiveSection());
function hideActiveSection() {
$childToHide.addClass('hidden');
$childToShow.show(300, function() {
$(this).removeClass('hidden');
});
}
});
};
slideSection();
How would I get the section I want to hide to do so persistently until I click the currently visible project image to show it? Could my CSS be interfering with what I want to do here? If so I'll post the code. Thanks!
I am having one html page in which all navigation (lets say them the TABS) resides.
I wrote a javascript to show one and hide another one on link click.
It works well on the tab i want but when i navigate to another tabs that div is showing on the bottom. I dont want it to display it in all other tabs.
This is my javascript code:
function displayBlock(divName){
if(document.getElementById("vend")) {
var oldDiv = document.getElementById("vend");
oldDiv.style.display = 'none';
//show div
var newDiv = document.getElementById(divName);
newDiv.style.display = 'block';
}
else{
var newDiv = document.getElementById(divName);
newDiv.style.display = 'none';
}
}
How to modify it to meet the need?
HTML Structure:
<div class="tab-content">
<div class="tab-pane" id="dashboard">
<div class="container">
<!-- Container code -->
</div>
</div>
<div class="tab-pane" id="vend">
<div class="container">
<!-- Container code -->
<a id="auto-topup2" href="dashboard#auto-topup" onclick="displayBlock('schedule');">
Schedule Autovend
</a>
</div>
</div>
<div class="tab-pane" id="commision">
<div class="container">
<!-- Container code -->
</div>
</div>
<div id="schedule" style="display:none">
<div class="tab-pane" id="auto-topup">
<div class="container">
<!-- Container code -->
</div>
</div>
</div>
In the vend section i have created a whose onclick will call the function and hide the Div with vend id and show Div with schedule ID....But the DIV with scehdule ID is showing in all the tabs..
I hope now it can be somewhat undestandable
To hide all tabs without the selected one you can use this function:
function displayBlock(idOfBlock) {
document.getElementByClass('block').style.display = 'none';
document.getElementById(idOfBlock).style.display = 'block'
}
<div class="block" id="hello">
hello
</div>
<div class="block" id="foobar">
foobar
</div>
