So I've got a header image that upon being clicked animates with transit, fades out, and fades back in with a new image. I'm then able to click on the new image and it will also animate and fade out to blank space. How can I continuously animate/fade through a series of ordered images - one new image per click ad infinitum?
Here's what I've got so far...
$(document).ready(function(){
$("#headuh").click(function(){
$("#headimg").transition({ skewY: '30deg' },1000);
$("#headimg").fadeOut(function() {
$(this).transition({ skewY: '00deg' }) .load(function() { $(this).fadeIn(); });
$(this).attr("src", "/imgurl.jpg");
You can use the javascript function called setInterval(); like this:
setInterval(function(){
//this code will keep on executing on every 2 seconds.
},2000)
The following snippet doesn't solve your problem exactly, but it might put you on the right track, as it randomly cycles through a set of 28 images with fading in and out. You can see it live at http://moodle.hsbkob.de:
<script src="jquery-1.4.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
var g_first_call = true;
var g_pic_old;
$(document).ready(function() {
pickPic();
setInterval("pickPic()", 7500);
});
function randomPic() {
do {
var pic = parseInt(28*Math.random()+1);
} while (pic == g_pic_old); // Don't want same pic twice
g_pic_old = pic;
document.getElementById("_image_").src = "./picfolder/picno" + pic + ".jpg";
}
function pickPic() {
if (g_first_call) {
randomPic();
g_first_call = false;
}
$("#_fadee_").fadeIn(750, function() {
$("#_fadee_").delay(6000).fadeOut(750, randomPic);
});
}
//]]>
</script>
<div id="_fadee_"><img id="_image_" alt="Image" /></div>

I have set up a rotating gallery on a homepage using the Javascript code below. The gallery works great, except I would like to have a different image show on refresh. What do I need to change in the code to make this happen? Thank you!
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script>
$.fn.preload = function() {
this.each(function(){
$('<img/>')[0].src = this;
});
}
var images = Array(
"1.jpg",
"2.jpg",
"3.jpg",
"4.jpg",
"5.jpg",
"6.jpg",
"7.jpg",
"8.jpg"
);
$([images[0],images[1],images[2],images[3],images[4]]).preload();
// Usage:
var currimg = 0;
$(document).ready(function(){
function loadimg(){
$('#outerWrapper').animate({ opacity: 1 }, 400,function(){
//finished animating, minifade out and fade new back in
$('#outerWrapper').animate({ opacity: 0.7 }, 100,function(){
currimg++;
if(currimg > images.length-1){
currimg=0;
}
var newimage = images[currimg];
//swap out bg src
$('#outerWrapper').css("background-image", "url("+newimage+")");
//animate fully back in
$('#outerWrapper').animate({ opacity: 1 }, 600,function(){
//set timer for next
setTimeout(loadimg,5000);
});
});
});
}
setTimeout(loadimg,5000);
});
</script>
You can set currimg to a random value from 0 to n, where n is the total number of images in the gallery. Upon refresh, the currently displayed image will be inclined to be different from the one displayed prior to refresh.
currimg = Math.floor(Math.random()*8);
Looking for a (simple) way to create a slideshow for my website I found the following question here: How to create image slideshow in html?. I borrowed the (corrected) code, adapted it to my needs and now I have what I wanted, but the transition between the images is too fast. It's not about the speed of the slideshow, but the blending or fading from one image into the next. The changes come too suddenly. I want them to happen gradually and smoothly. What can I add to it or how can I change it to slow it down? Here is it:
<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
var step=1;
function slideit()
{
document.images.slide.src = eval("image"+step+".src");
if(step<2)
step++;
else
step=1;
setTimeout("slideit()",2500);
}
slideit();
</script>
</body>
Thank you for your help.
You can do it by doing following change in your code
setTimeout(slideit(),10000);
instead of
setTimeout(slideit(),2500);
Here 2500 means 2.5 seconds and 10000 means 10 seconds, according to need you can use any parameter.
Hope this can solve your problem.
As per your comment, you want to show the transition between image changes, then use jquery and do this in sequence:
Animate opacity to 0 (fadeOut),
change the image,
animate the opacity to 1 (fadeIn)
or write your own animation logic to do the same without jquery.
Solution using jquery:
var $slide = $(document.images.slide);
function slideit() {
//fadeout the last image.
$slide.fadeOut(function () {
document.images.slide.src = eval("image" + step + ".src");
//after changing the image, fadeIn the new image.
$slide.fadeIn(function () {
if (step < 2) step++;
else step = 1;
//everything is done... now run the timer for next slide.
setTimeout(slideit, 5500);
});
})
}

I just made this program for slide show it is working well but i want to use previous and next buttons in the slide show and i don't have any idea how to do that so i put this here please help for the same
var image1=new Image()
image1.src="slide/23.jpg"
var image2=new Image()
image2.src="slide/7.jpg"
var image3=new Image()
image3.src="slide/4.jpg"
var image4=new Image()
image4.src="slide/5.jpg"
var image5=new Image()
image5.src="slide/6.jpg"
</script>
<img id="myImg"src="slide/2.jpg" name="img" width="1000" height="250"/>
<script>
var step=1
function slideImages(){
if (!document.images)
return
document.images.img.src=eval("image"+step+".src")
if (step<5)
step++
else
step=1
setTimeout("slideImages()",3000)
}
slideImages()
</script>
You probably want to abstract away some code so it can be easily reused in your functions:
// Dealing with the counter:
var step;
var steps = 5;
function increment() {
s = (s + 1) % steps;
}
function decrement() {
s--;
if (s<0) s = steps-1;
}
// Dealing with the slide show:
function show() {
document.images.img.src=eval("image"+step+".src")
}
function next() {
increment();
show();
}
function prev() {
decrement();
show();
}
// Automatic sliding:
window.setInterval(next, 3000);
Also, i would reconsider your approach to storing images:
function createImgBySource(src){
var img = new Image();
img.src = src;
return img;
}
var images = [
createImgBySource('slide/23.jpg'),
createImgBySource('slide/7.jpg'),
createImgBySource('slide/4.jpg'),
createImgBySource('slide/5.jpg'),
createImgBySource('slide/6.jpg')
];
Now you can change the increment and decrement functions to use images.length instead of steps, so you can add more images without having to alter other variables. Also, your show() function should look like this (getting rid of the nasty eval):
function show() {
document.images.img.src = images[step];
}
Try the below code
var ss = new TINY.fader.init("ss", {
id: "slides", // ID of the slideshow list container
position: 0, // index where the slideshow should start
auto: 0, // automatic advance in seconds, set to 0 to disable auto advance
resume: true, // boolean if the slideshow should resume after interruption
navid: "pagination", // ID of the slide nav list
activeClass: "current", // active class for the nav relating to current slide
pauseHover: true, // boolean if the slideshow should pause on slide hover
navEvent: "click", // click or mouseover nav event toggle
duration: .25 // duration of the JavaScript transition in seconds, else the CSS controls the duration, set to 0 to disable fading
});
got from Here also here is a sample Fiddle
I would consider using something like jCarousel.
I think you are best putting all of your images into an array and then looking over it. I am assuming that the image tag with the ID 'myImg' is the one that you want to update, as such you should use document.getElementByID('myImg') and not document.images.img.src=eval("image"+step+".src") -- eval should also be avoided as the performance is poor and it can be dangerous.
Put this as the end of your page:
<script type="text/javascript">
(function(){
var step = 0;
var images = [image1, image2, image3, image4, image5];
var image = document.getElementByID('myImg');
var slideImages = function() {
image.src = images[step].src;
step++;
if (step == images.length){
step == 0;
}
setTimeout("slideImages()", 3000);
};
slideImages()
})();
</script>
Trying to get images to refresh themselves with javascript a set number of times, then stop (to avoid large cache generation). This code won't function though, so not sure what's missing?
<script>
var c = 0;
function fnSetTimer()
{
document.getElementById('refreshimage1').src='http://68.116.42.142:8080/cam_4.jpg?\'+new Date().getMilliseconds();
var t = setTimeout(fnSetTimer,5000);
c=c+1;
if(c>5)
clearTimeout(t);
}
</script>
<img src="http://68.116.42.142:8080/cam_4.jpg"; id="refreshimage1" onload="fnSetTimer()" width="400" />
However, this code does work:
<img src="http://68.116.42.142:8080/cam_4.jpg"; id="refreshimage2" onload="setTimeout('document.getElementById(\'refreshimage2\').src=\'http://68.116.42.142:8080/cam_4.jpg?\'+new Date().getMilliseconds()', 5000)" width="400" />
So if you place both side by side, the bottom image will refresh (indefinitely), but the top image just loads once and never refreshes. Any thoughts what I missed in the top code?
The problem is that the function re-loads the image, which calls the function, which re-loads the image...
You also had a problem with the image url - '\' is used to escape special characters, if you want a slash you need two - '\\'
PUT THIS IN YOUR HEADER
<script language="javascript">
function fnSetTimer(image, src, counter, limit)
{
image.onload = null;
if(counter < limit)
{
counter++;
setTimeout(function(){ fnSetTimer(image, src, counter, limit); },5000);
image.src= src+ '?\\'+new Date().getMilliseconds();
alert(counter); // show frame number
}
}
</script>
PUT THIS IN THE BODY
<img src="http://68.116.42.142:8080/cam_4.jpg"; id="refreshimage1" onload="fnSetTimer(this, this.src, 0, 5);" width="400" />
This should fix it for you - it only fires onLoad once and then loops through 5 times, and you should be able to edit the image tag in Wordpress, etc.
MAKE SURE YOU GIVE EACH IMAGE A DIFFERENT ID
I have this simple image zoom jQuery. Here is a Demo example. It uses the elevateZoom jQuery.
The code behind is very simple:
<img id="zoom_05" src='small_image1.png' data-zoom-image="large_image1.jpg"/>
<script>
$vc("#zoom_05").elevateZoom({
zoomType : "inner",
cursor: "crosshair"
});
</script>
My question, is how can i make the large image load on demand, only when the mouse is over it. Please have a look at this demo example and let me know what i need to add in the code.
img element (id="zoom_05") above, would not load large_image1.jpg on its own.
Large image load happens because elevateZoom() looks into its data-zoom-image value and immediately loads it. One way around this behaviour is to defer elevateZoom() until user hover's over the small image for the first time. Quick example:
jQuery( function () {
var elevate_zoom_attached = false, $zoom_05 = $("#zoom_05") ;
$zoom_05.hover(
// hover IN
function () {
if ( ! elevate_zoom_attached ) {
$zoom_05.elevateZoom({
zoomType : "inner",
cursor : "crosshair"
});
elevate_zoom_attached = true ;
};
},
// hover OUT
function () {
if ( elevate_zoom_attached) { // no need for hover any more
$zoom_05.off("hover");
}
}
);
}) ;
Mind you this is an quick, on-top-of-my-head code, but should work ...
Also in this case elevateZoom() action might not be immediate while large image loading is going on.
I used this idea to initiate zoom on any number of images on the same page by adding a zoom class to the image. It works without any HOVER OUT
<img class="zoom" src="myimage.png" data-zoom-image="mybigimage.png"/>
$('.zoom').hover(
// hover IN
function () {
var currImg = $(this); //get the current image
if (!currImg.hasClass('zoomon')) { //if it hasn't been initialized
currImg.elevateZoom(); //initialize elevateZoom
currImg.addClass('zoomon'); //add the zoomon class to the img so it doesn't re-initialize
}
})
