W3 Schools slideshow doesn't automatically load page - javascript

I used the W3Schools example on how to load a slideshow, and the animations work perfectly, but it only comes up with three dots. I have to click on one of them for the picture to show up.
var slideIndex = 0;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}

I think your issue is related with the loading of the javascript code because you are loading it within the head element and in this case you have to ensure that the javascript code is executed when the DOM is loaded.
To solve it you can load the javascript code before the </body> tag to ensure that the DOM is loaded before the javascript is executed
Another approach could be to use jQuery to see when the document is ready, you could do:
$( document ).ready(function() {
showSlides(slideIndex);
});
But I prefer to load the javascript code at the bottom instead of using jQuery to avoid using another library. Besides, in my opinion it has a better performance because, if the javascript code is executed at the top of the document, it will be a visual delay before the end user sees the actual page.

Slideshow images with JS and CSS showing all at once

I'm using basic code to make images slideshow but when I open the page it doesn't show up, rather only the dot buttons - which when pressed correctly show up the image. I want only 1 image to be showing when the page is opened up.
I tried tweaking the CSS which seems to be the problem.
.mySlides {
display: none;
}
When set to "none" it shows nothing but the dots, If I remove display: none; all images show together one beneath the other.
var slideIndex = 1;
showSlides(slideIndex);
// Next/previous controls
function plusSlides(n) {
showSlides(slideIndex += n);
}
// Thumbnail image controls
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {
slideIndex = 1
}
if (n < 1) {
slideIndex = slides.length
}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex - 1].style.display = "block";
dots[slideIndex - 1].className += " active";
}

Image in slider dissapear after few seconds

I'm implementing a simple image slider in my Middleman project. The images show up and the bullets are clickable. The images are linked with image_tags in Middleman. However, after an image appears it disappears after a few seconds! The only thing I could find which could have an effect on this would be the fade-in option.
After extensively looking with the inspector I couldn't find anything which causes the image not to show up.
Below my current code.
HTML
<div class="slideshow-container">
<!-- Full-width images with number and caption text -->
<div class="mySlides fade">
<div class="numbertext">1 / 3</div>
<%= image_tag "img3.jpeg", :class => "slider-img"%>
<div class="text">Caption Text</div>
</div>
<div class="mySlides fade">

<%= image_tag "img3.jpeg", :class => "slider-img"%>
<div class="text">Caption Two</div>
</div>

Move hidden part of div into view using CSS and javascript only

I have two divs, one encompassing the other. The inside div contains a list of items displayed horizontally with the condition (overflow-x: hidden). I have two buttons (moveRight, and moveLeft). The user should be able to click the buttons to view the rest of the items in the list that were initially hidden. For reference, I am trying to emulate something like this: https://codepen.io/anon/pen/RjYLmr
__________________
| (viewable frame)|
| |
item_one item_two item_three item_four item_five
|_________________|
*** Next viewable frame after moveRight is pushed.
__________________
| (viewable frame)|
| |
item_one item_two item_three item_four item_five
|_________________|
But I cannot use JQuery, also it should only slide to the next frame as opposed to all the way on each click. Please help, I am a new at front-end development.
Try to create a slideshow

just change images with div/span/a/ you need and then play a little with css
here is my exemple for you ;)

How to add current image file name to a slider

The Javascript
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}
So I changed the prev and next arrows to the top as that's where I need them to be. I'm adding 3 menus as the images and I need it to say page 1 of 3, page 2 of 3, and page 3 of 3 depending on which menu they are on. So I guess I will need to change the image file name to "page 1 of 3", "page 2 of 3", and "page 3 of 3" to make it work like I need it to. So how can I show the current file name in between my prev and next arrows?
I hope this all make's sense! Any help would be appreciated!!
Thanks!
You can try getting the source of your image tag from within JavaScript and use that to update the caption text
var ctext = slides[slideIndex - 1].childNodes[1].getAttribute("src")
slides[slideIndex - 1].childNodes[2].innerHTML = ctext

Why won't the images pop up immediately on my image carousel?

I am working on an image carousel for a fictional company about airplanes. I will do much more styling later, so please excuse the extreme blandness of the code. I have a few stock images I pulled from the internet. It is really confusing me as I don't know what I did wrong. Thank you for taking the time to read my post, it really means a lot. Why won't the images pop up? Here is my code:
Html:
<div class="bulkOfPage">
<!-- Image Carousel Goes Here -->
<!-- Work More on This -->
<div class="slideshow-container">
<div class="mySlides fade">
<div class="numbertext">1 / 3</div>
<img src="img/airplanes-work-1.jpg" style="width:100%">
<div class="text">Our fleet is the most updated in the business, with our planes being decked out in the latest equipment</div>
</div>
<div class="mySlides fade">
<div class="numbertext">2 / 3</div>
<img src="img/landing1015-airplane.jpg" style="width:100%">
<div class="text">We have the most trained pilots in the industry, and this gives the smoothest landings you will find.</div>
</div>
<div class="mySlides fade">
<div class="numbertext">3 / 3</div>
<img src="img/download.jpeg" style="width:100%">
<div class="text">We have landing rights at almost all of the major airports around the world.</div>
</div>
<a class="prev" onclick="plusSlides(-1)">❮</a>
<a class="next" onclick="plusSlides(1)">❯</a>
</div>
<br>
<div style="text-align:center">
<span class="dot" onclick="currentSlide(1)"></span>
<span class="dot" onclick="currentSlide(2)"></span>
<span class="dot" onclick="currentSlide(3)"></span>
</div>
And my CSS:
* {box-sizing:border-box}
/* Slideshow container */
.slideshow-container {
max-width: 1000px;
position: relative;
margin: auto;
}
.mySlides {
display: none;
}
/* Next & previous buttons */
.prev, .next {
cursor: pointer;
position: absolute;
top: 50%;
width: auto;
margin-top: -22px;
padding: 16px;
color: white;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
}
/* Position the "next button" to the right */
.next {
right: 0;
border-radius: 3px 0 0 3px;
}
/* On hover, add a black background color with a little bit see-through */
.prev:hover, .next:hover {
background-color: rgba(0,0,0,0.8);
}
/* Caption text */
.text {
color: #f2f2f2;
font-size: 15px;
padding: 8px 12px;
position: absolute;
bottom: 8px;
width: 100%;
text-align: center;
}
/* Number text (1/3 etc) */
.numbertext {
color: #f2f2f2;
font-size: 12px;
padding: 8px 12px;
position: absolute;
top: 0;
}
/* The dots/bullets/indicators */
.dot {
cursor:pointer;
height: 13px;
width: 13px;
margin: 0 2px;
background-color: #bbb;
border-radius: 50%;
display: inline-block;
transition: background-color 0.6s ease;
}
.active, .dot:hover {
background-color: #717171;
}
/* Fading animation */
.fade {
-webkit-animation-name: fade;
-webkit-animation-duration: 1.5s;
animation-name: fade;
animation-duration: 1.5s;
}
#-webkit-keyframes fade {
from {opacity: .4}
to {opacity: 1}
}
#keyframes fade {
from {opacity: .4}
to {opacity: 1}
}
And finally, the JavaScript:
$(document).ready(function(){
var slideIndex = 0;
showSlides();
function showSlides() {
var i;
var slides = document.getElementsByClassName("mySlides");
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
slideIndex++;
if (slideIndex> slides.length) {slideIndex = 1}
slides[slideIndex-1].style.display = "block";
setTimeout(showSlides, 2000); // Change image every 2 seconds
}
});
Thank you so much for reading my post, it really means a lot to me. Thanks! Have a fantastic day!
This should work. I added functionality for your next/prev buttons, and the dot buttons.
Notice, what happens inside document.ready cannot be accessed with triggers like div onclick="plusSlides(1)", because of scope. So either you define functions outside of document.ready, or instead of onclick="" you use the jQuery way, like: $('.dot').click
Personally, I don't like that you use 1-based index. I think it adds to the confusion; it adds -1, +1 ,... I would suggest you use 0 based index in the future. Don't try for the first element to have 1 as index.
