Page FadeIn and FadeOut Transition

I am currently trying to create a script that makes fading transition from page to page when clicking a anchorlink. I have already made the script, but it does not seem to work.
My code look like this:
$("body").load(function() {
$(this).fadeIn(200);
});
$("a").click(function() {
$link = $(this).attr("href");
$("body").fadeOut(200);
window.location.replace($link);
});
It does not seem to make the fadeIn and fadeOut transitions. It is still the normal pageload.

First hide the body of the page on page load then
you need to place the redirecting line in the complete function of fadeOut
Try this code:
$(document).ready(function() {
$('body').hide().fadeIn(200);
$("a").click(function(e) {
e.preventDefault();
$link = $(this).attr("href");
$("body").fadeOut(200,function(){
window.location = $link;
});
});
});

You need to hide the element initially, either with .hide() or with CSS display:none;.
$(document).ready(function() {
$('body').hide().fadeIn(200);
});

You have to use setTimeout to time the window.location.replace() to execute after the current body has faded like :
$("a").click(function() {
$link = $(this).attr("href");
$("body").fadeOut(200);
setTimeout(function(){
window.location.replace($link);
},200);
return false;
});
Remember to return false at then end of the function else the default action of the link click i.e. redirection precedes any other action associated with the anchor.
But, sincerely, this will give you a smooth fading effect from the current page but not a smooth effect on the redirected page unless it's implemented by you.

This is four years later, but just in case someone needs it. I agree with Roko about the flickering, so I initially hid the body with CSS instead of putting .hide() before the fade in effect:
body {
display: none;
}
Also some have mentioned using .fadeOut(), but it doesn't work on Chrome. I switched to .show() and .hide() which seems to work great. It also animates all of the elements as it fades, which produces a need transition without a hefty jQuery plugin.
$(document).ready(function() {
$('body').show(500);
$("a").click(function() {
$link = $(this).attr("href");
setTimeout(function(){
window.location.replace($link);
},1000);
$("body").hide(500);
return false;
});
});
Lastly, I'm using this on a page that contains click-to-scroll navigation like most one-pagers, as well as opening new tabs with target="_blank", so I changed $("a") to $(".transition-link") and added class="transition-link" to the links I want to navigate from.

whole page moves a bit when a show function is executed

I am trying to build my first website www.angelosmavraidis.com
I have inserted a javascript to show 8 divs of the same class when clicking on the "artwork" div.
The problem is that when the "artwork" is clicked and the rest of the divs show up the whole page moves a bit to the left.
Anyone know why this is happening?
Also can you recommend a better alternative to the following script to do the job?
$(document).ready(function(e) {
$('.mainmenu').each(function(index, element) {
$(this).click(function() {
$('.artwork').eq(index).show();
});
});
});
Thanks

Use preventDefault here like
$(document).ready(function(e) {
$('.mainmenu').each(function(index, element) {
$(this).click(function(ev) {
ev.preventDefault();
$('.artwork').eq(index).show();
});
});
});

Display loading animation while part of page loads via jQuery's load()

On my site I want to load "pages" dynamicly via jQuery's load() function and I would like to add a loading animation.
function loadPage(){
$("#content").load("example.html");
}
Where would I put code to show <div id="loading"></div> while jQuery loads that content??
Thanks In Advance.

Use the callback function of .load() to hide the loading div when it is finished.
function loadPage(){
$('#loading').show();
$("#content").load("example.html", function () { //calback function
$('#loading').hide();
});
}

You can try something like this:
$(document).ready(function() {
$(this).ajaxSend(function() {
$(this).append('<div id="loading"></div>');
}).ajaxStop(function() {
$('#loading').remove();
});
});
Which will work for all of your ajax calls...

I don't know exactly what you want to do, but probably you want to load content to a div.
You should create a css class:
.loading {
background: url(loading.gif) center center;
}
and add this class to your div (after you clear it) with addClass() when you start loading, and remove it with removeClass in .load callback.

Using fade in/fade out with jquery

I am working over on of my student projects and I am new jquery, for the project I have to use jquery to enhance few function and I have learned much to carry out basic tasks, but I am stuck over something very confusing.
One my scripts actually changes the image of a div container at mouse over function, function is currently fine but make it feel a little beautiful I want to add transition affects to it either through fade in fade out functions or through animate but am unable to work it out with both. I searched over internet but here i am unable to relate those examples to mind here.
I just want to know where can I insert fade in fade out or animate function in this code, to give it a transitioning effect:
$(document).ready(function () {
$(".thumb").hover(function () {
var dummyImg = $(this).attr("alt");
$(this).attr("alt", $(this).attr("src"));
$(this).attr("src", dummyImg);
}, function () {
var dummyImg = $(this).attr("src");
$(this).attr("src", $(this).attr("alt"));
$(this).attr("alt", dummyImg);
});
});
Thank-you!

You want to access the callback function of the fadeIn and fadeOut functions, this will allow you to make changes to the src image and what not. it would look something like this ->
$(document).ready(function () {
$(".thumb").hover(function () {
var dummyImg = $(this).attr("alt");
$(this).fadeOut('slow', function(){
//this is now the callback.
$(this).attr("alt", $(this).attr("src"));
$(this).attr("src", dummyImg);
$(this).fadeIn('slow');
});
}, function () {
var dummyImg = $(this).attr("src");
$(this).fadeOut('slow', function(){
//this is now the callback.
$(this).attr("src", $(this).attr("alt"));
$(this).attr("alt", dummyImg);
$(this).fadeIn('slow');
});
});
});

Maven,
Have you thought of using css webkit? This SO article goes into detail for crossfading images - at different rates. CSS Webkit Transition - Fade out slowly than Fade in
You can also make use of a basic event to fade-in/fade-out the image. This JQuery/JSFiddle SO article makes use of the this reference object: Jquery fadeOut on hover
The basic fade-in / fade-out structure from the JSFiddle.net documention is as follows:
$('#show').hover(function() {
$(this).stop(true).fadeTo("slow", 0);
}, function() {
$(this).stop(true).fadeTo("slow", 1);
});

Personaly, I'd layer the two images (css) so the non-hover version is normally on top. Then
in the hover function, add a $(this).fadeOut('fast') so that the underlying image is displayed.

http://jsfiddle.net/Xm2Be/13/ There is an example how you could do that. Ofcourse, you can set lenght of fade effect by placing some number inside brackets. For examle .fadeToggle(5000) will have timing of 5 seconds.

Adjusting height of scrolling div

I am combining two scripts together: a scroller and a content fader. When I swap the content (fading), div's with a lot of content make the scrolling div super long. I was reading on the plugin demo for content scrolling (http://manos.malihu.gr/jquery-custom-content-scroller) that you can use $(selector).mCustomScrollbar("update"); when loading different content to make the div adjust accordingly.
I know that code needs to go in my fading script somewhere, but where? Here is the fading script, where would it go?
<script type='text/javascript'>//<![CDATA[
$(window).load(function(){
(function($) {
$.fn.Fader = function() {
this.each(function() {
$('.clickme').bind('click', function(e) {
e.preventDefault();
$( "#mediaswap div" ).fadeOut();
$( "#mediaswap div" + $(this).attr('name') ).fadeIn();
})
});
}
})(jQuery);
$(function() {
$('#mediaswap').Fader();
});
});//]]>
</script>

I've answered your comment on the post but I'm writing it here too.
Since you fade in/out divs, you have to call the update method as a callback to the .fadeIn() function, so it updates the scrollbar after the animation is completed:
$( "#mediaswap div" + $(this).attr('name') ).fadeIn(function(){
$(this).mCustomScrollbar("update");
});
Additionally, there's an extra option parameter you can use when you initially call the plugin, that checks content size and updates the scrollbar automatically if it changes:
$("#mediaswap div").mCustomScrollbar({
advanced:{ updateOnContentResize:true }
});
Using the updateOnContentResize option, depends on the rest of your code (where you call the plugin), so I recommend using the first method.

I recommend checking the div to see if it's animated using something like this:
var wait = setInterval(function() {
if( !$("#mediaswap div").is(":animated"))
{
clearInterval(wait);
//put the code in here because it checks
for whether the DIV is currently animated.
}
}, 200);
You can change the interval if it takes the animation longer to complete the animation.
