I code simple slide show using setInterval and also I have 2 jQuery functions for toggle div. Code seems working, but there is small issue. When I navigate to site toggle div part is working perfectly. But when first slide changes toggle functions stop working.
$(document).ready(function () {
var ImageCount = 1;
var ImageTotal = 3;
setInterval(function SlideAuto() {
if (ImageCount == 1) {
ImageCount = ImageCount + 1;
} else {
if (ImageCount < ImageTotal) {
ImageCount = ImageCount + 1;
} else {
if (ImageCount == ImageTotal) {
ImageCount = 1;
}
}
}
var ImageURL = 'img/SliderIMG/' + ImageCount + '.jpg';
$("#SliderIMG").attr('src', ImageURL);
}, 3000);
$("#tab1").click(function () {
$("#con1").toggle("fade");
$("#con2").toggle("fade");
});
$("#tab2").click(function () {
$("#con1").toggle("fade");
$("#con2").toggle("fade");
});
});

Hi friends,
I want to make autoplay image in this slider but setInterval is not working,
can you say what is wrong in here?
Thank you
Your function adds an eventlistener but it will only work when there will be an event(which is click in this case)
You can use swiperjs, it has many types of features and framework/library implentations. https://swiperjs.com/swiper-api
I don't know if this question has been asked before or not. But...
I have the following JavaScript code in my HTML file:
<img id="imageDisplay">
<script type="text/javascript">
var displayImage = document.querySelector( '#imageDisplay' );
var imageArray = [ 'http://www.joongcho.com/Images/30th-Bday-Party-01.jpg',
'http://www.joongcho.com/Images/30th-Bday-Party-02.jpg',
'http://www.joongcho.com/Images/30th-Bday-Party-03.jpg',
'http://www.joongcho.com/Images/30th-Bday-Party-04.jpg',
'http://www.joongcho.com/Images/30th-Bday-Party-05.jpg',
'http://www.joongcho.com/Images/30th-Bday-Party-06.jpg' ];
var imageCount = 0;
var imageLength = imageArray.length;
displayImage.setAttribute( 'src', imageArray[ imageCount ] );
function nextImage(imageCount) {
}
function previousImage(imageCount) {
}
</script>
I'm trying to put a next Image and a previous Image function for this HTML.
For the next image, if there are more than 1 images and the image is not the last image, then there should be a link that allows a user to click through the array forwards. Also, if the image is the last image in the array, then the link is hidden.
For the previous image, if the image is not the first image of the array, then there should be a link that allows a user click through the array backwards. if the image is the first image, then the previous link should be hidden.
Any help is appreciated.
You have to attach event listeners to buttons or links (I used buttons):
var displayImage = document.getElementById('imageDisplay');
var buttonPrev = document.getElementById('button-prev');
var buttonNext = document.getElementById('button-next');
var imageArray = [ '../Images/30th-Bday-Party-01.jpg',
'../Images/30th-Bday-Party-02.jpg',
'../Images/30th-Bday-Party-03.jpg',
'../Images/30th-Bday-Party-04.jpg',
'../Images/30th-Bday-Party-05.jpg',
'../Images/30th-Bday-Party-06.jpg' ];
var imageCount = 0;
var imageLength = imageArray.length;
function nextImage () {
imageCount++;
if (imageCount >= imageLength - 1) {
buttonNext.style.display = 'none';
imageCount = imageLength - 1;
}
if (imageCount < imageLength) {
displayImage.setAttribute('src', imageArray[imageCount]);
}
if (imageCount > 0) {
buttonPrev.style.display = 'inline';
}
}
function previousImage () {
imageCount--;
if (imageCount <= 0) {
buttonPrev.style.display = 'none';
imageCount = 0;
}
if (imageCount >= 0) {
displayImage.setAttribute('src', imageArray[imageCount]);
}
if (imageCount < imageLength) {
buttonNext.style.display = 'inline';
}
}
displayImage.setAttribute('src', imageArray[imageCount]);
displayImage.textContent = imageCount;
buttonPrev.style.display = 'none';
buttonNext.addEventListener('click', nextImage);
buttonPrev.addEventListener('click', previousImage);
<img id="imageDisplay" />
<button id="button-prev">Back</button>
<button id="button-next">Forward</button>
Of course, you can't look at the images yet.
How can i improve image slider transition. It is rather erratic. I want it to be smooth (smooth in and out properly). The problem is image only fadeIn, i cannot figure out how to fadeOut.
var nextimage = 0;
var timer = 0;
doSlideshow();
function doSlideshow() {
if (nextimage >= images.length) {
nextimage = 0;
}
$('.col-md-8')
.css('background-image', 'url("' + images[nextimage++][0] + '")')
.fadeIn(3000, function() {
timer = setTimeout(doSlideshow, 3000);
});
}
$(".col-md-8").hover(function() {
clearTimeout(timer);
});
$(".col-md-8").mouseout(function() {
setTimeout(doSlideshow, 3000);
});
Pen
setInterval(function(){
$("#top").fadeOut(function() {
$(this).attr("src","http://1.bp.blogspot.com/-cFt5KNrHsHc/TZMH6XUBu-I/AAAAAAAAAR4/R6hOP7lffx0/s1600/apple-logo.png").fadeIn().delay(1000).fadeOut(function(){
$(this).attr('src', 'http://coreldrawtips.com/images/applebig.jpg').fadeIn().delay(1000);
});
}
);
}, 400
Check this link also.
I have fixed this for you, you do not need settimeout for this kind of stuff, there are many other ways.
function doSlideshow() {
if (nextimage >= images.length) {
nextimage = 0;
}
$('.col-md-8')
.css('background-image', 'url("' + images[nextimage++][0] + '")');
$('.col-md-8').hide().fadeIn(3000).fadeOut(2000, function() {
doSlideshow()
});
}
Link to codepen, there is bit more to say about this, which I will do later.
http://codepen.io/damianocel/pen/PzQwNr
I have the following code:
var logo1 = "//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_2x.png";
var logo2 = "//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_hover_2x.png";
var images = new Array (logo1, logo2);
var index = 1;
function rotateImage()
{
$('.logoimage').fadeOut('fast', function()
{
$(this).attr('src', images[index]);
$(this).fadeIn('fast', function()
{
if (index == images.length-1)
{
index = 0;
}
else
{
index++;
}
});
});
}
$(document).ready(function()
{
setInterval (rotateImage, 5000);
});
var images = new Array (logo2);
var index = 1;
function rotateImage()
{
$('.logoimage').fadeOut('fast', function()
{
$(this).attr('src', images[index]);
$(this).fadeIn('fast', function()
{
if (index == images.length-1)
{
index = 0;
}
else
{
index++;
}
});
});
}
$(document).ready(function()
{
setInterval (rotateImage, 5000);
});
Its working well apart from the following bugs:
Image loads even though image already is showing on page.
I have an image onmousehover effect on that image and its causing bad effect.
Is it possible to interchange between the image src and the img onmousehover src?
Thanks
Alex
you can change the src of the img tag using JavaScript as below,
function hover(element) {
element.setAttribute('src', '//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_2x.png');
}
function unhover(element) {
element.setAttribute('src', '//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_hover_2x.png');
}
and the html be
<img id="my-img" src="http://dummyimage.com/100x100/000/fff" onmouseover="hover(this);" onmouseout="unhover(this);" />
After Edit :
If you want to change it on some timeout, You need to put your below code inside window.onload = function() {}
var images = new Array();
images[0] = "logo_1.png";
images[1] = "logo_2.png";
var images = new Array();
for (var i = 0; i < 2; i++) {
images.push("logo_" + i + ".png");
}
var x = 0;
function changeImage() {
document.getElementById('ad').src = images[x];
if (x < 8) {
x += 1;
} else {
x = 0;
}
if (window.addEventListener) {
window.addEventListener('load', changeImg, false);
}
function changeImg() {
var x = 0;
setInterval(function() {
changeImage()
},5000);
}
HTML:
<img id="ad" src="//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_2x.png" />
Use jQuery hover to run code when hovering in or out of an element. Also use setTimeout to run code after a delay.
var logo1 = "//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_2x.png";
var logo2 = "//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_hover_2x.png";
$(function() {
$('.logoimage').hover(function() {
setTimeout(function() {
$('.logoimage').attr('src', logo2);
}, 1000);
}, function() {
setTimeout(function() {
$('.logoimage').attr('src', logo1);
}, 1000);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<img class="logoimage" src="//cdn.shopify.com/s/files/1/0816/3411/t/3/assets/logo_2x.png">
My application is a MVC, using MS SQL to get the image file names. I am using the following script to preload images; would like to know How I can display hourglass cursor while waiting to complete the preload.
function preload_images() {
var i, count = 0;
$('#selector').css('cursor', 'wait');
for (i = 1; i < sl; i++) {
images[i] = new Image();
images[i].onload = images[i].onerror = function () {
count++;
if (count == sl) {
$('#selector').css('cursor', 'default');
}
}
images[i].src = impath.toString() + im.toString() + i + ".jpg";
}
}
It works great first time, however, when I change the file name from a dropdownlist, the hourglass does not stop even all images are load. Thanks in advance.
From the code above you are loading sl-1 images, but the condition to stop the wait cursor is sl images(if (count == sl)), so change it to if (count == (sl-1))
Thanks to Musa for providing the initial solution, here is the way I got it to work, just in case someone is looking for it:
var images = [];
function preload_images() {
showLoadingImage();
$('#selector').css('cursor', 'wait');
for (i = tochar; i < sl; i++) {
images[i] = new Image();
var name = impath.toString() + imStart.toString() + i + ext;
images[i].src = 'ImageHandler.ashx?img=' + name + '&window=50&level=50 &slice=0';
if (i == sl - 1) {
images[i].onload = images[i].onerror = function () {
$('#selector').css('cursor', 'Default');
hideLoadingImage(this);
};
}
}
}
function showLoadingImage() {
$('#imagediv').append('<div id="imagediv1"><img src="../Content/images/ajax-loader2.gif" alt="Loading..." /></div>');
$('#imagediv1').show();
}
function hideLoadingImage(img) {
$('#imagediv1').hide();
img.onload = img.onerror = null;
}
