How can I create an efficient infinitely looping waving text animation?

This is the effect I am trying to create (JSFiddle):
$('.header h1 span').each(function() { // each letter is contained inside a <span> element
var that = $(this);
setTimeout(function() {
that.animate({
top: "-10px"
}, animateTime / 2)
.animate({
top: "10px"
}, animateTime / 2);
}, that.index() * 100);
});
Result:
It appears to be successful. However, I ran into the problem of it looking like this after switching tabs, then coming back:
In the fiddle above, I've tried to "fix" this by making the animation stop when the tab is unfocused. It's better than when I WASN'T checking for tab unfocusing, but it still has problems. This is the code I'm using to do that:
var running = true;
document.addEventListener('visibilitychange', function(){
console.log("Running:" + running);
running = !document.hidden;
if(!running) clearQueues();
})
If the user spends less than a couple seconds unfocused from the tab, the animation looks like the second GIF again, and I don't see a way to avoid that. I've tried using requestAnimationFrame() but I can't figure out how to make it behave correctly.
So, my question is: how do I prevent the animation from being affected by the tab being unfocused?
Bonus points (figuratively) if you can help me make it more efficient on mobile, too.

I'm not sure if this solves the stuttering for you or not. This strategy is similar in concept to what you are doing, but uses CSS animation rather than js.
(function(){
var el = document.querySelectorAll(".wavey")[0];
var oldText = el.innerText
var newHtml = "";
for (var i in el.innerText) { newHtml += ("<span style='animation-delay: " + i/10 + "s;'>" + oldText[i] + "</span>"); }
el.innerHTML = newHtml;
})();
#keyframes wave {
from { transform: translateY(0); }
to { transform: translateY(-1em); }
}
h1.wavey { margin-top: 2em; }
h1.wavey span {
display: inline-block;
animation-duration: 1s;
animation-name: wave;
animation-iteration-count: infinite;
animation-direction: alternate;
animation-timing-function: ease-in-out;
}
<h1 class="wavey">Hello World</h1>

Flashing text on value change [duplicate]

I'm brand new to jQuery and have some experience using Prototype. In Prototype, there is a method to "flash" an element — ie. briefly highlight it in another color and have it fade back to normal so that the user's eye is drawn to it. Is there such a method in jQuery? I see fadeIn, fadeOut, and animate, but I don't see anything like "flash". Perhaps one of these three can be used with appropriate inputs?

My way is .fadein, .fadeout .fadein, .fadeout ......
$("#someElement").fadeOut(100).fadeIn(100).fadeOut(100).fadeIn(100);
function go1() { $("#demo1").fadeOut(100).fadeIn(100).fadeOut(100).fadeIn(100)}
function go2() { $('#demo2').delay(100).fadeOut().fadeIn('slow') }
#demo1,
#demo2 {
text-align: center;
font-family: Helvetica;
background: IndianRed;
height: 50px;
line-height: 50px;
width: 150px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button onclick="go1()">Click Me</button>
<div id='demo1'>My Element</div>
<br>
<button onclick="go2()">Click Me</button> (from comment)
<div id='demo2'>My Element</div>

You can use the jQuery Color plugin.
For example, to draw attention to all the divs on your page, you could use the following code:
$("div").stop().css("background-color", "#FFFF9C")
.animate({ backgroundColor: "#FFFFFF"}, 1500);
Edit - New and improved
The following uses the same technique as above, but it has the added benefits of:
parameterized highlight color and duration
retaining original background color, instead of assuming that it is white
being an extension of jQuery, so you can use it on any object
Extend the jQuery Object:
var notLocked = true;
$.fn.animateHighlight = function(highlightColor, duration) {
var highlightBg = highlightColor || "#FFFF9C";
var animateMs = duration || 1500;
var originalBg = this.css("backgroundColor");
if (notLocked) {
notLocked = false;
this.stop().css("background-color", highlightBg)
.animate({backgroundColor: originalBg}, animateMs);
setTimeout( function() { notLocked = true; }, animateMs);
}
};
Usage example:
$("div").animateHighlight("#dd0000", 1000);

You can use css3 animations to flash an element
.flash {
-moz-animation: flash 1s ease-out;
-moz-animation-iteration-count: 1;
-webkit-animation: flash 1s ease-out;
-webkit-animation-iteration-count: 1;
-ms-animation: flash 1s ease-out;
-ms-animation-iteration-count: 1;
}
#keyframes flash {
0% { background-color: transparent; }
50% { background-color: #fbf8b2; }
100% { background-color: transparent; }
}
#-webkit-keyframes flash {
0% { background-color: transparent; }
50% { background-color: #fbf8b2; }
100% { background-color: transparent; }
}
#-moz-keyframes flash {
0% { background-color: transparent; }
50% { background-color: #fbf8b2; }
100% { background-color: transparent; }
}
#-ms-keyframes flash {
0% { background-color: transparent; }
50% { background-color: #fbf8b2; }
100% { background-color: transparent; }
}
And you jQuery to add the class
jQuery(selector).addClass("flash");

After 5 years... (And no additional plugin needed)
This one "pulses" it to the color you want (e.g. white) by putting a div background color behind it, and then fading the object out and in again.
HTML object (e.g. button):
<div style="background: #fff;">
<input type="submit" class="element" value="Whatever" />
</div>
jQuery (vanilla, no other plugins):
$('.element').fadeTo(100, 0.3, function() { $(this).fadeTo(500, 1.0); });
element - class name
first number in fadeTo() - milliseconds for the transition
second number in fadeTo() - opacity of the object after fade/unfade
You may check this out in the lower right corner of this webpage: https://single.majlovesreg.one/v1/
Edit (willsteel) no duplicated selector by using $(this) and tweaked values to acutally perform a flash (as the OP requested).

You could use the highlight effect in jQuery UI to achieve the same, I guess.

If you're using jQueryUI, there is pulsate function in UI/Effects
$("div").click(function () {
$(this).effect("pulsate", { times:3 }, 2000);
});
http://docs.jquery.com/UI/Effects/Pulsate

$('#district').css({opacity: 0});
$('#district').animate({opacity: 1}, 700 );

Pure jQuery solution.
(no jquery-ui/animate/color needed.)
If all you want is that yellow "flash" effect without loading jquery color:
var flash = function(elements) {
var opacity = 100;
var color = "255, 255, 20" // has to be in this format since we use rgba
var interval = setInterval(function() {
opacity -= 3;
if (opacity <= 0) clearInterval(interval);
$(elements).css({background: "rgba("+color+", "+opacity/100+")"});
}, 30)
};
Above script simply does 1s yellow fadeout, perfect for letting the user know the element was was updated or something similar.
Usage:
flash($('#your-element'))

You could use this plugin (put it in a js file and use it via script-tag)
http://plugins.jquery.com/project/color
And then use something like this:
jQuery.fn.flash = function( color, duration )
{
var current = this.css( 'color' );
this.animate( { color: 'rgb(' + color + ')' }, duration / 2 );
this.animate( { color: current }, duration / 2 );
}
This adds a 'flash' method to all jQuery objects:
$( '#importantElement' ).flash( '255,0,0', 1000 );

You can extend Desheng Li's method further by allowing an iterations count to do multiple flashes like so:
// Extend jquery with flashing for elements
$.fn.flash = function(duration, iterations) {
duration = duration || 1000; // Default to 1 second
iterations = iterations || 1; // Default to 1 iteration
var iterationDuration = Math.floor(duration / iterations);
for (var i = 0; i < iterations; i++) {
this.fadeOut(iterationDuration).fadeIn(iterationDuration);
}
return this;
}
Then you can call the method with a time and number of flashes:
$("#someElementId").flash(1000, 4); // Flash 4 times over a period of 1 second

How about a really simple answer?
$('selector').fadeTo('fast',0).fadeTo('fast',1).fadeTo('fast',0).fadeTo('fast',1)
Blinks twice...that's all folks!

I can't believe this isn't on this question yet. All you gotta do:
("#someElement").show('highlight',{color: '#C8FB5E'},'fast');
This does exactly what you want it to do, is super easy, works for both show() and hide() methods.

This may be a more up-to-date answer, and is shorter, as things have been consolidated somewhat since this post. Requires jquery-ui-effect-highlight.
$("div").click(function () {
$(this).effect("highlight", {}, 3000);
});
http://docs.jquery.com/UI/Effects/Highlight

function pulse() {
$('.blink').fadeIn(300).fadeOut(500);
}
setInterval(pulse, 1000);

I was looking for a solution to this problem but without relying on jQuery UI.
This is what I came up with and it works for me (no plugins, just Javascript and jQuery);
-- Heres the working fiddle -- http://jsfiddle.net/CriddleCraddle/yYcaY/2/
Set the current CSS parameter in your CSS file as normal css, and create a new class that just handles the parameter to change i.e. background-color, and set it to '!important' to override the default behavior. like this...
.button_flash {
background-color: #8DABFF !important;
}//This is the color to change to.
Then just use the function below and pass in the DOM element as a string, an integer for the number of times you would want the flash to occur, the class you want to change to, and an integer for delay.
Note: If you pass in an even number for the 'times' variable, you will end up with the class you started with, and if you pass an odd number you will end up with the toggled class. Both are useful for different things. I use the 'i' to change the delay time, or they would all fire at the same time and the effect would be lost.
function flashIt(element, times, klass, delay){
for (var i=0; i < times; i++){
setTimeout(function(){
$(element).toggleClass(klass);
}, delay + (300 * i));
};
};
//Then run the following code with either another delay to delay the original start, or
// without another delay. I have provided both options below.
//without a start delay just call
flashIt('.info_status button', 10, 'button_flash', 500)
//with a start delay just call
setTimeout(function(){
flashIt('.info_status button', 10, 'button_flash', 500)
}, 4700);
// Just change the 4700 above to your liking for the start delay. In this case,
//I need about five seconds before the flash started.

Would a pulse effect(offline) JQuery plugin be appropriate for what you are looking for ?
You can add a duration for limiting the pulse effect in time.
As mentioned by J-P in the comments, there is now his updated pulse plugin.
See his GitHub repo. And here is a demo.

Found this many moons later but if anyone cares, it seems like this is a nice way to get something to flash permanently:
$( "#someDiv" ).hide();
setInterval(function(){
$( "#someDiv" ).fadeIn(1000).fadeOut(1000);
},0)

The following codes work for me. Define two fade-in and fade-out functions and put them in each other's callback.
var fIn = function() { $(this).fadeIn(300, fOut); };
var fOut = function() { $(this).fadeOut(300, fIn); };
$('#element').fadeOut(300, fIn);
The following controls the times of flashes:
var count = 3;
var fIn = function() { $(this).fadeIn(300, fOut); };
var fOut = function() { if (--count > 0) $(this).fadeOut(300, fIn); };
$('#element').fadeOut(300, fIn);

If including a library is overkill here is a solution that is guaranteed to work.
$('div').click(function() {
$(this).css('background-color','#FFFFCC');
setTimeout(function() { $(this).fadeOut('slow').fadeIn('slow'); } , 1000);
setTimeout(function() { $(this).css('background-color','#FFFFFF'); } , 1000);
});
Setup event trigger
Set the background color of block element
Inside setTimeout use fadeOut and fadeIn to create a little animation effect.
Inside second setTimeout reset default background color
Tested in a few browsers and it works nicely.

Like fadein / fadeout you could use animate css / delay
$(this).stop(true, true).animate({opacity: 0.1}, 100).delay(100).animate({opacity: 1}, 100).animate({opacity: 0.1}, 100).delay(100).animate({opacity: 1}, 100);
Simple and flexible

$("#someElement").fadeTo(3000, 0.3 ).fadeTo(3000, 1).fadeTo(3000, 0.3 ).fadeTo(3000, 1);
3000 is 3 seconds
From opacity 1 it is faded to 0.3, then to 1 and so on.
You can stack more of these.
Only jQuery is needed. :)

There is a workaround for the animate background bug. This gist includes an example of a simple highlight method and its use.
/* BEGIN jquery color */
(function(jQuery){jQuery.each(['backgroundColor','borderBottomColor','borderLeftColor','borderRightColor','borderTopColor','color','outlineColor'],function(i,attr){jQuery.fx.step[attr]=function(fx){if(!fx.colorInit){fx.start=getColor(fx.elem,attr);fx.end=getRGB(fx.end);fx.colorInit=true;}

Unfortunately the top answer requires JQuery UI. http://api.jquery.com/animate/
Here is a vanilla JQuery solution
http://jsfiddle.net/EfKBg/
JS
var flash = "<div class='flash'></div>";
$(".hello").prepend(flash);
$('.flash').show().fadeOut('slow');
CSS
.flash {
background-color: yellow;
display: none;
position: absolute;
width: 100%;
height: 100%;
}
HTML
<div class="hello">Hello World!</div>

Here's a slightly improved version of colbeerhey's solution. I added a return statement so that, in true jQuery form, we chain events after calling the animation. I've also added the arguments to clear the queue and jump to the end of an animation.
// Adds a highlight effect
$.fn.animateHighlight = function(highlightColor, duration) {
var highlightBg = highlightColor || "#FFFF9C";
var animateMs = duration || 1500;
this.stop(true,true);
var originalBg = this.css("backgroundColor");
return this.css("background-color", highlightBg).animate({backgroundColor: originalBg}, animateMs);
};

This one will pulsate an element's background color until a mouseover event is triggered
$.fn.pulseNotify = function(color, duration) {
var This = $(this);
console.log(This);
var pulseColor = color || "#337";
var pulseTime = duration || 3000;
var origBg = This.css("background-color");
var stop = false;
This.bind('mouseover.flashPulse', function() {
stop = true;
This.stop();
This.unbind('mouseover.flashPulse');
This.css('background-color', origBg);
})
function loop() {
console.log(This);
if( !stop ) {
This.animate({backgroundColor: pulseColor}, pulseTime/3, function(){
This.animate({backgroundColor: origBg}, (pulseTime/3)*2, 'easeInCirc', loop);
});
}
}
loop();
return This;
}

Put this together from all of the above - an easy solution for flashing an element and return to the original bgcolour...
$.fn.flash = function (highlightColor, duration, iterations) {
var highlightBg = highlightColor || "#FFFF9C";
var animateMs = duration || 1500;
var originalBg = this.css('backgroundColor');
var flashString = 'this';
for (var i = 0; i < iterations; i++) {
flashString = flashString + '.animate({ backgroundColor: highlightBg }, animateMs).animate({ backgroundColor: originalBg }, animateMs)';
}
eval(flashString);
}
Use like this:
$('<some element>').flash('#ffffc0', 1000, 3);
Hope this helps!

Here's a solution that uses a mix of jQuery and CSS3 animations.
http://jsfiddle.net/padfv0u9/2/
Essentially you start by changing the color to your "flash" color, and then use a CSS3 animation to let the color fade out. You need to change the transition duration in order for the initial "flash" to be faster than the fade.
$(element).removeClass("transition-duration-medium");
$(element).addClass("transition-duration-instant");
$(element).addClass("ko-flash");
setTimeout(function () {
$(element).removeClass("transition-duration-instant");
$(element).addClass("transition-duration-medium");
$(element).removeClass("ko-flash");
}, 500);
Where the CSS classes are as follows.
.ko-flash {
background-color: yellow;
}
.transition-duration-instant {
-webkit-transition-duration: 0s;
-moz-transition-duration: 0s;
-o-transition-duration: 0s;
transition-duration: 0s;
}
.transition-duration-medium {
-webkit-transition-duration: 1s;
-moz-transition-duration: 1s;
-o-transition-duration: 1s;
transition-duration: 1s;
}

just give elem.fadeOut(10).fadeIn(10);

This is generic enough that you can write whatever code you like to animate. You can even decrease the delay from 300ms to 33ms and fade colors, etc.
// Flash linked to hash.
var hash = location.hash.substr(1);
if (hash) {
hash = $("#" + hash);
var color = hash.css("color"), count = 1;
function hashFade () {
if (++count < 7) setTimeout(hashFade, 300);
hash.css("color", count % 2 ? color : "red");
}
hashFade();
}

you can use jquery Pulsate plugin to force to focus the attention on any html element with control over speed and repeatation and color.
JQuery.pulsate() * with Demos
sample initializer:
$(".pulse4").pulsate({speed:2500})
$(".CommandBox button:visible").pulsate({ color: "#f00", speed: 200, reach: 85, repeat: 15 })

Loop and interval hybrid in javascript?

I wrote some JQuery and JS to power a single message element that:
reads a new message from an array for each loop
starts off-screen,
animates right, to center screen for 1/4 of the loop duration
waits at the center to be read for 1/2 of the loop duration
animates right again, off screen for another fourth of the loop duration
changes to the next loop with a new message
repeats
And what sounds like a simple task became (in relation to the feature) many lines of code:
function flow(i, duration){
var message = Game.activities[i]
var transTime = duration / 4;
var idleTime = duration / 2;
var windowDouble = $(window).width() * 2;
$(".message-flow").text(message);
$(".message-flow")
.animate({transform:"translateX(-" + windowDouble + "px)"},0)
.animate({transform:"translateX(0px)"},transTime)
.delay(idleTime)
.animate({transform:"translateX(" + windowDouble + "px)"},transTime);
}
function flowFunc(i, duration){
return function(){
flow(i, duration);
}
}
function activityFlowInit(duration){
var delay = 0;
for (var i = 0; i < Game.activities.length; i++){
setTimeout(flowFunc(i, duration),delay);
delay += duration;
}
totalDuration = duration * Game.activities.length;
setTimeout(function(){
activityFlowInit(duration);
},totalDuration);
}
Which produces a timing flaw where the message slowly begins to change during the transition period rather than when hidden;
I then thought of removing all of this code (which handles closures, in the midst of it all) and replacing the message's animation functionality with 11 simple lines of CSS:
.message{
animation: transit 4s;
animation-iteration-count:infinite;
}
#keyframes transit
{
0% {transform:translateX(-150%)}
25% {transform:translateX(50%)}
75% {transform:translateX(50%)}
100% {transform:translateX(150%)}
}
Afterwards changing the message at a set interval, in coordination with the time that the message is off screen.
However, I don't know how I can do this.
I'm thinking I need some sort of hybrid of setInterval and a loop; a loop that only loops after an interval of time has passed.
How is this (or the next best thing) achieved?

I started thinking about the way a loop and setInterval() works, and I realized that what a loop is really doing is setting an interval of 0, checking a condition and then incrementing a variable. I can make my own for loop-setInterval hybrid by setting the interval, (in my case) skipping the condition, and incrementing my own variable.
JS:
var i = 0;
var messages = ["message 1", "message2", "message 3"];
function writeAdd() { // Handling the closure
return function () {
$(".message").text(messages[i]);
//if (condition === true){ // condition excluded
i++;
if(i === messages.length) i = 0; //creating the loop's repetition
//}
};
}
function loopMessage(duration) {
$(".message").css("-webkit-animation-play-state","running");
setInterval(writeAdd(), duration); //setting the interval
}
loopMessage(4000);
CSS:
.message-flow{
-webkit-animation: transit 8s;
-webkit-animation-iteration-count:infinite;
-webkit-animation-play-state:paused;
}
#-webkit-keyframes transit {
0% {
-webkit-transform:translateX(-2000px);
}
25% {
-webkit-transform:translateX(0px);
}
75% {
-webkit-transform:translateX(0px);
}
100% {
-webkit-transform:translateX(2000px);
}
}

Moving Background image in a loop from left to right

I would like to have a moving background image on my page from left to right exactly the same way as in following website http://kxip.in , please suggest how to achieve this.
Thanks & Regards

An interesting question with a challenging solution. Thankfully, stackoverflow.com is here to help you do your work!
Obviously, you'll need jQuery! So, grab some jQuery and then come back.
Back? Great.
Let's start off. First, add this bit of line to your code:
$(function(){
})
So, what is that $ magic stuff? Nevermind you actually learning that! We're here to get answers, not learn! But, if you're the curious type, open up a new tab and ask the following question on stackoverflow.com, "what is this $(function(){ }) stuff". Someone will fill you in! Don't forget to tag JQUERY!
Ok, we want to animate a background image. TOUGH. Of course, there are a lot of ways to do this (HTML, CSS, and JAVASCRIPT always have more than one way to do this!) but I prefer the JQuery way. Remember that weird dollar signy stuff at the top? Let's go back to that!
$(function(){
setInterval(function(){
}, 500);
})
We just added some more programs! setInterval is a counter that counts up to 500 milliseconds and then runs the code inside. Why 500? I don't know, I just like magic numbers. So we have a timerjiggymathing, we need some more programs in it. How do we add a background?
$(function(){
setInterval(function(){
$('body').css('background-position', '0 0');
}, 500);
})
Ok, now we're getting somewhere! Our jQueries are actually now setting the background position to 0, 0. Not so interesting yet. Let's see if we can do some more.
$(function(){
var x = 0;
setInterval(function(){
x-=1;
$('body').css('background-position', '0 ' + x + 'px');
}, 500);
})
Let's test it out!

Oh man. That image is way too big and the stupid kitten is going UP! Back to the codes.
$(function(){
var x = 0;
setInterval(function(){
x-=1;
$('body').css('background-position', x + 'px 0');
}, 500);
})

Ahhh, more like it! But, man...is it awfully slow. Let's upgrade that!
$(function(){
var x = 0;
setInterval(function(){
x-=1;
$('body').css('background-position', x + 'px 0');
}, 10);
})

OH SNAPPPPPP. We got some scrolling kittenz now! JavaQuery is AWESOME!
To be honest though, that background image isn't doing justice. Time to update that!

Oh yeah, now we're kicking!!!
SO, there you have it! 1 of many, MANY ways to do what you want to do.
GOOD LUCK. HAVE FUN.

Here is a css solution:
FIDDLE
body {
background: url(http://kxip.in/images/mohalistadium.jpg) repeat;
-webkit-animation: loader 16s steps(100) infinite;
-moz-animation: loader 16s steps(100) infinite;
-ms-animation: loader 16s steps(100) infinite;
-o-animation: loader 16s steps(100) infinite;
animation: loader 16s steps(100) infinite;
}
#-webkit-keyframes loader {
from {
background-position: 0;
}
to {
background-position: -1600px 0;
}
}
#-moz-keyframes loader {
from {
background-position: 0;
}
to {
background-position: -1600px 0;
}
}
#-ms-keyframes loader {
from {
background-position: 0;
}
to {
background-position: -1600px 0;
}
}
#-o-keyframes loader {
from {
background-position: 0;
}
to {
background-position: -1600px 0;
}
}
#keyframes loader {
from {
background-position: 0;
}
to {
background-position: -1600px 0;
}
}

Its easy! Just use some simple javascript!
Checkout the jsFiddle
Code:
<html>
<head>
<title>BackGround Slide</title>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript">
// speed in milliseconds
var scrollSpeed = 70;
// set the default position
var current = 0;
// set the direction
var direction = 'h';
function bgscroll() {
// 1 pixel row at a time
current -= 1;
// move the background with backgrond-position css properties
$('body').css("backgroundPosition", (direction == 'h') ? current + "px 0" : "0 " + current + "px");
}
//Calls the scrolling function repeatedly
setInterval("bgscroll()", scrollSpeed);
</script>
<style type="text/css">
body {
background-image: url('http://kxip.in/images/mohalistadium.jpg');
}
</style>
</head>
<body>
</body>
</html>

Use some js/jQuery:
function move(){
var element = $('#selector');
element .css('background-position-x', (parseInt(element.css('background-position-x') - 10));
//Check if need to reset background-position-x to origin.
}

you can use marquee tag in HTML5. you can see the examples in http://www.quackit.com/html/codes/html_marquee_code.cfm.

The easiest way to achieve this i believe is to use using a little bit of Javascript.
You can find the javascript they user to use as an example here:
http://kxip.in/js/background-moving.js
// speed in milliseconds
var scrollSpeed = 70;
// set the default position
var current = 0;
// set the direction
var direction = 'h';
function bgscroll() {
// 1 pixel row at a time
current -= 1;
// move the background with backgrond-position css properties
$('div.background-image').css("backgroundPosition", (direction == 'h') ? current+"px 0" : "0 " + current+"px");
}
//Calls the scrolling function repeatedly
setInterval("bgscroll()", scrollSpeed);
I urge you however not to simply copy and paste because this will likely not work for you.

jQuery .Animate Opacity and .FadeOut/In Both Not Working Inside SetInterval

I trying to make what appears to the user to be an image fader. A string of images fade into each other. All the solutions that I found were complex, and normally required an for every image. I've come up with what should be a simple solution. It's working 90% on Firefox/Chrome/IE11 on Windows. On Android Chrome it's having issues.
Basically my idea is, I have two divs, absolutely positioned, one on top of the other. Both start with a background, sized to cover. The top one fades out, revealing the bottom one, and at the end of the animation, the background-image of the top one (current hidden) is changed to image 3. After a pause, it fades back in, and the background-image of the bottom one is changed to image 4. This repeats indefinitely.
HTML:
<div class="slideshow" id="slideshow-top"></div>
<div class="slideshow" id="slideshow-bottom"></div>
CSS:
.slideshow {
display:block;
background-size:cover;
width: 100%;
height: 100%;
position:absolute;
top:0;
left:0;
}
#slideshow-top {
z-index:-5;
background-image:url(http://www.andymercer.net/wp-content/uploads/2013/12/slider-1.jpg);
}
#slideshow-bottom {
z-index:-10;
background-image:url(http://www.andymercer.net/wp-content/uploads/2013/12/slider-2.jpg);
}
Javascript:
var url_array = [
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-1.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-2.jpg',

];
var count = 1;
setInterval(function() {
if (count%2) { // Fade In
jQuery('#slideshow-top').animate({opacity:0}, '200000', function() {
jQuery('#slideshow-top').css('background-image','url('+url_array[count]+')');
});
}
else { //Fade Out
jQuery('#slideshow-top').animate({opacity:1}, '200', function() {
jQuery('#slideshow-bottom').css('background-image','url('+url_array[count]+')');
});
}
count = (count == url_array.length-1 ? 0 : count + 1);
}, 2000);
http://jsfiddle.net/5eXy9/
As seen in the Fiddle above, this mostly works. However, it seems to ignore the length of the animation. Using .fadeOut has the same effect. I've tried going from 200 to 20000, and there doesn't seem to be a difference.
I'm not sure if this is tied into the other issue, which is that on Android (Galaxy S4, Chrome, Android 4.x), the animation doesn't occur at all. It simply changes images. Any ideas?
EDIT: Jan 10 - Timing problem is fixed, but the main issue (Android) is still unsolved. Any thoughts?

The interval keeps going, so when increasing the animation speed, you have increase the interval speed as well.
The way you've built this, you should always keep the speed of both animations equal to the interval, or if you need a delay, increase the interval compared to the animations so it at least has a higher number than the highest number used in the animations.
The reason changing the speed doesn't work at all for you, is because it should be integers, not strings, so you have to do
jQuery('#slideshow-top').animate({opacity:0}, 200000, function() {...
// ^^ no quotes
I would do something like this
var url_array = [
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-1.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-2.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-3.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-4.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-5.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-6.jpg',
'http://www.andymercer.net/wp-content/uploads/2013/12/slider-7.jpg',
'http://www.walldoze.com/images/full/2013/12/04/wallpapers-desktop-winter-nature-x-wallpaper-backgrounds-natureabstract-designs-interesting-hd-19045.jpg'];
var count = 1;
var speed = 2000,
delay = 1000;
$.each(url_array, function(source) { // preload
var img = new Image();
img.src = source;
});
setInterval(function () {
if (count % 2) { // Fade In
jQuery('#slideshow-top').animate({
opacity: 0
}, speed, function () {
jQuery('#slideshow-top').css('background-image', 'url(' + url_array[count] + ')');
});
} else { //Fade Out
jQuery('#slideshow-top').animate({
opacity: 1
}, speed, function () {
jQuery('#slideshow-bottom').css('background-image', 'url(' + url_array[count] + ')');
});
}
count = (count == url_array.length - 1 ? 0 : count + 1);
}, speed + delay);
