Below is my original question and code but per CoreyRS's comment let me add some detail. I want to create a div that falls own the page and disappears like a rock falling through the air. The catch is it must work in IE 9 and 8. I have found some CSS3 animations that work great in all but IE. Any help is appreciated. Please provide code examples.
Original Question and Code
I am attempting to use the slideDown animation in jQuery to animate a div. The idea is a div will show then slide down the page and then fade out. Preferably it would fade out while falling but I cannot even get the div to fall. Here is my code:
JS:
var $j = jQuery.noConflict();
$j(window).load(function() {
$j('#loading').fadeOut('slow', function() { //fade out loading div
$j("#content-wrap").fadeIn("slow", function() { // show content div
setTimeout( function() { // delay slideDown effect
$j('#animate').slideDown('slow', function() {
// script to fade out or hide animate div
}, 2000 );
});
});
});
});
HTML:
<div id="loading">
<h2 class="textcenter">Loading...</h2>
<img id="loading-image" class="center" src="/images/ajax-loader.gif" />
</div>
<div id="content-wrap" class="hide">
<div id="animate">
<img class="fear" src="/sign.png" />
</div>
<div class="img-center">
<img class="feature-image" src="/Prairie-Grass.jpg" />
</div>
</div>
What am I doing wrong and I will take any advice that will create a falling div on the screen that fades out that will work in IE 9 and 8.
Haven't tested but give this a go. You'll need to edit the width/height properties etc to your needs, and obviously don't use inline styling if you have a css stylesheet.
<style>
#animate {
width:100px;
height:100px;
position:fixed;
top:-100px;
left:50%;
margin-left:50px;
z-index:1;
}
</style>
<script>
var $j = jQuery.noConflict();
$j(window).load(function() {
$j('#loading').fadeOut('slow', function() {
$j("#content-wrap").fadeIn("slow", function() {
$j('#animate').delay(2000).animate({'top':'50%'}, 500);
$j('#animate').delay(2000).fadeOut(500);
});
});
});
</script>

I have a very simple script to switch out divs. I would like to add in a fading transition to the script so that it is a bit smoother. However I cannot see what I am doing wrong (totally JS incompetent)
Thanks for any advice.
jQuery(document).ready(function( $ ) {
$('#div2, #div3').hide();
$('.show').click(function () {
$('.targetDiv').hide().fadeOut(1000);
$('#div' + $(this).attr('target')).show();
});
});
Your problem lies in this line: $('.targetDiv').hide().fadeOut(1000);
What is does - it sets style display: none; to all your elements you plan to cross-fade.
Also use the right attributes: data-target="#div1" instead of target="#div1" (which is not used for that purpose)
Instead:
jQuery(function($) { // DOM ready
// get all your targetDiv elements
var $fadeDivs = $(".targetDiv");
// Hide all but this one
$fadeDivs.not("#div1").hide();
$('.show').click(function(evt) {
// prevent the browser doing default stuff
evt.preventDefault();
// get the target element - using data-target attribute!
var selector = $(this).data('target');
var $target = $( selector );
// crossfade (don't forget to use .stop())
$fadeDivs.not($target).stop().fadeOut(1000);
$target.stop().fadeIn(1000);
});
});
.targets{ position:relative; height:100px; }
.targetDiv { position:absolute; height:100px; top:0; left:0;}
<div class="targets">
<div id="div1" class="targetDiv"><img src="//placehold.it/100x100/0bf"></div>

I am working on a website that the background image will fade from one to another, I have it setup and working about 98%. There is just one little problem. When it first loads and does it's first fade it fades to white and then to the image, instead of fading straight into the next image. After that it work beautifully. This is using jQuery 1.9 and I have jQuery noConflict on since the previous developer coded the sites menu using MooTools.
<html>
<head>
<script src="js/jquery.js">
</script>
<script>
var $s = jQuery.noConflict();
function swapImages(){
var $sactive = $s('#myGallery .active');
var $snext = ($s('#myGallery .active').next().length > 0) ? $s('#myGallery .active').next() : $s('#myGallery img:first');
$snext.fadeIn(1500).addClass('active');
$sactive.fadeOut(2000, function(){
});
$sactive.removeClass('active');
};
$s(document).ready(function(){
// Run our swapImages() function every 5secs
setInterval('swapImages()', 5000);
});
</script>
</head>
<style>
#myGallery{
position:relative;
width:100%; /* Set your image width */
height:auto; /* Set your image height */
}
#myGallery img{
display:none;
position:absolute;
top:0;
width: 100%;
left:0;
}
#myGallery img.active{
display:block;
}
.home-page-rotator{
position:absolute;
width:100%;
z-index:-10;
}
</style>
<body>
<div class="home-page-rotator" id="myGallery">
<img src="images/1.jpg" class="active" />
<img src="images/2.jpg" />
<img src="images/3.jpg" />
</div>
</body>
</html>
I took out all the content so you can test if you wanted but the is everything that runs the background rotation and fade. Also I have the CSS in a seperate file but for posting to here I just put it inline so you can see the CSS behind the code. Let me know what I should do to fix this?
Moving the remove class method to the function call of the fadeout seems to work better for me (at least in Chrome):
<script>
var $s = jQuery.noConflict();
function swapImages(){
var $sactive = $s('#myGallery .active');
var $snext = ($s('#myGallery .active').next().length > 0) ? $s('#myGallery .active').next() : $s('#myGallery img:first');
$sactive.fadeOut(2000, function(){
$sactive.removeClass('active');
});
$snext.fadeIn(1500).addClass('active');
};
$s(document).ready(function(){
// Run our swapImages() function every 5secs
setInterval('swapImages()', 5000);
});
</script>
I ran into this problem a while back and I found the easiest solution was to switch from img elements to using two divs and the background-image css url to display your images. I made a simple slider for that a while back. You're welcome to copy whatever you need from it.
Background slider source
In essence, if you have two divs that are absolutely positioned as the background elements, you can cycle their z-indexes and fade them in and out. Furthermore, you can load the next image in a constructed img element and once it has loaded, change the background-image of the hidden div and fade to it. This means that there is no loading shown and you can fade directly into the slideshow.
Here's some pseudo code below, but it would probably be easier to just look at the real functions in the source.
base.next_slide = function () {
"current slide" = "next slide";
base.containers[the_shown_container].fadeOut(duration,function () {
$(this).css({'background-image':'url("' + "Next image url" + '")',
"z-index":"-2"});
base.containers[the_next_container].css("z-index","-1");
$(this).show();
the_shown_container = the_next_container;
});
};
Plugin.prototype.init = function (base) {
$('<img/>').attr('src', "Next image url").load(function() {
base.containers[the_next_container].css('background-image', 'url(' + "Next image url" + ')');
if ("there's only one image in the slider"){
base.containers[the_shown_container].fadeOut(duration,function () {
$(this).css("z-index","-2");
base.containers[the_next_container].css("z-index","-1");
});
return;
}
base.next_slide();
setInterval(base.next_slide ,base.o.interval);
});
};
I am new to coding and need help with jQuery. I have 2 <div>s (one with an image, the other with a menu list, both 50% width) and I need to be able to click one of the menu options to make a new div (50% width) appear from the right while reducing the other 2 divs width to 25% each. Then clicking on the same menu option to hide the new div and revert back to the original widths. But if I click on another menu option while the new div is visible, I need it to change the content to that specific menu option content.
How can I swap the left-hand <div> out with jQuery?

Here's a working jsFiddle with the styles: http://jsfiddle.net/YcphY/6/
For starters, here's a method that ties the below examples of how to do this into the animation you're after:
$(function() {
$("#nav").delegate("li","click", function() {
var newDiv = $(".box3 .content").eq($(this).index()-1);
newDiv.siblings().hide().end(); // hide the others
if(newDiv.is(":visible")) {
// if shown, fade it out, when the fade finishes, slide everything back
newDiv.fadeOut(function() {
$(".box3").hide();
$(".box1, .box2").animate({ width: "50%" });
});
} else {
// if not shown, then slide over space, then fade in
$(".box1, .box2").animate({ width: "25%" }, function() {
$(".box3").show();
newDiv.fadeIn("fast");
});
}
});
});
Given your current CSS you can do this:
$(function() {
$("#nav").delegate("li a","click", function() {
$(".box3").show();
$("#" + $(this).text()).show().siblings().hide();
});
});
Here's a working example, though you can see the CSS will need a bit of work to get it going 100%. I suggest a few changes though: give your links and containers matching IDs, like this:
<li><a id="ad">ADVERTISING</a></li>
<div id="ad-container" class="content">ADVERTISING</div>
Then the JS can be:
$(function() {
$("#nav").delegate("li a","click", function() {
$(".box3").show();
$("#" + this.id + "-container").show().siblings().hide();
});
});
Here's a working example of that...it allows you to change the text at will and not worry about the JS breaking later. Another alternative yet is to go off the index of the link in the list using .index() of the <li>, if the number of links was consistent with the <div>s in all cases, even if there's an offset because of the "hello!" link.
Here's an example of an index approach with your current HTML:
$(function() {
$("#nav").delegate("li","click", function() {
$(".box3").show();
$(".box3 .content").hide().eq($(this).index()-1).show();
});
});
I think jQuery's animate function might be of use to you.
What you'd need to do is either have a hidden div positioned out of the window added to your HTML (or maybe add it dynamically using jquery on document.ready event, if you prefer) and the use the above mentioned animate function to slide it in and out and bind it to the menu item's click function.
Sample Code
$(document).ready(function(){
$('#slide').click(function(){
var hidden = $('.hidden');
if (hidden.hasClass('visible')){
hidden.animate({"left":"-1000px"}, "slow");
hidden.removeClass('visible');
} else {
hidden.animate({"left":"0px"}, "slow");
hidden.addClass('visible');
}
});
});
Explanation
In the above code we are binding code to the click event of an element with a id "slide". Once the element is clicked the code gets initiated. We check if the .hidden has a css class called "visible". If not we animate the hidden div to slide in. and if it has a visible class then slide it out.
Working Fiddle
Here is a working JSFiddle for you
Some pointers
In the hidden div's CSS remember to specify a z-index greater than that of the current left panel.
In the hidden div's CSS remember to set position to absolute and left to around -1200px (or greater than window.width() to make it work on all screen sizes.)
I'm having some slight problems with fading one div into another, here's my code (and test page):
HTML:
<div id="grid">
<div class="grid-box">
<div class="phase-1">
<img class="grid-image" src="http://teamworksdesign.com/v2/wp-content/themes/default/images/dtr.jpg" alt="" height="152" width="210" />
<div class="grid-heading">
<h2>DTR Medical</h2>
<h3>Branding, Web, Print</h3>
</div>
</div>
<div class="phase-2">
<div class="grid-info">
<h4>Probeything 2000</h4>
<p>Marketing unglamorous single-use medical intruments is not simple. We helped Neurosign increasetheir sales by 25% and increasemarket awareness.</p>
</div>
<div class="grid-heading-hover">
<h2>DTR Medical</h2>
<h3>Branding, Web, Print</h3>
</div>
</div>
</div>
</div>
Javascript:
<script type="text/javascript">
$(document).ready(function(){
$(".phase-2").hide();
});
$(function(){
$('.grid-box').hover(
function(){
$('.grid-box .phase-1').fadeOut(200, function(){
$('.grid-box .phase-2').fadeIn(200);
});
},
function(){
$('.grid-box .phase-2').fadeOut(200, function(){
$('.grid-box .phase-1').fadeIn(200);
});
}
);
});
</script>
CSS:
.phase-1 .grid-image {
width:210px;
height:220px;
overflow:hidden;
}
.phase-2 {
position:relative;
top:-220px;
}
UPDATE:
I have one "working" (see test link in question). Is it possible to stop it fading to white then fading in the next phase? I want to fade the two div into each other rather than to white first.
If you type $ on the console, it answer undefined, so it probably was redefined by some other script. To use $ meaning jQuery again, use the following syntax
$(document).ready(function($) {
// $ means jQuery again in here
});
Notice the $ as the first argument of the function call.

I have two large image files in a div on a page that take several seconds to load. How can I hide the loading content while a "loading gif" appears and then have the content appear once it has fully loaded?
I don't really know anything about javascript but I tried using this code. It did half of what I wanted it to do. The "loading gif" worked but the problem was that the content was visible as it was loading.
http://aaron-graham.com/test2.html
<div id="loading" style="position:absolute; width:95%; text-align:center; top:300px;">
<img src="img/parallax/ajax-loader.gif" border=0>
</div>
<script>
var ld=(document.all);
var ns4=document.layers;
var ns6=document.getElementById&&!document.all;
var ie4=document.all;
if (ns4)
ld=document.loading;
else if (ns6)
ld=document.getElementById("loading").style;
else if (ie4)
ld=document.all.loading.style;
function init()
{
if(ns4){ld.visibility="hidden";}
else if (ns6||ie4) ld.display="none";
}
</script>
Any help would be greatly appreciated!
Use jquery, with code like:
$(document).ready(function(){
$('#pic1').attr('src','http://nyquil.org/uploads/IndianHeadTestPattern16x9.png');
});
With the html like:
<img id="pic1" />
It works by running when document's ready function is called (which is called after the DOM and other resources have been constructed), then it will assign the img's src attribute with the image's url you want.
Change the nyquil.org url to the image you want, and add as many as needed (just don't go overboard ;). Tested Firefox 3/chrome 10.
Here is the demo: http://jsfiddle.net/mazzzzz/Rs8Y9/1/
Working off your HTML structure I added a notifyLoaded class for the two images so you can watch for when both have loaded via an onload event. Since css background images don't get that event I've created a hidden img using the background's path so we can test when that image is loaded
HTML:
<div id="loading">
<img src="http://aaron-graham.com/img/parallax/ajax-loader.gif" border="0" />
</div>
<div id="vertical">
<div>
<div class="panel">
<img class="notifyLoaded" src="http://aaron-graham.com/img/parallax/tile3.png" />
</div>
</div>
</div>
<div id="imgLoader">
<img class="notifyLoaded" src="http://aaron-graham.com/img/parallax/deepspace3.jpg" alt="" />
</div>
You have reference to jQuery in your page already so I've replaced your script to the following.
jQuery:
$(document).ready(function() {
var $vertical = $('#vertical');
var $imgs = $('.notifyLoaded');
var imgCount = $imgs.length;
var imgLoadedCount = 0;
$vertical.backgroundparallax(); // Activate BG Parallax plugin
$imgs.load(function() {
console.log(this);
imgLoadedCount++;
if (imgCount == imgLoadedCount) {
// images are loaded and ready to display
$vertical.show();
// hide loading animation
$('#loading').hide();
}
});
});
I've also set #Vertical to a default display:none; which gets changed when images have loaded
CSS:
body {background-color:black;}
#loading {position:absolute;width:95%;text-align:center;top:300px;}
#vertical {display:none;background-image: url('http://aaron-graham.com/img/parallax/deepspace3.jpg');background-position: 0 0;height: 650px;width: 900px;overflow: auto;margin:35px auto auto auto;}
#vertical > div {margin: 0;color: White;}
#vertical .panel {padding: 100px 5%;margin-left:40px;height: 3363px;}
#imgLoader {display:none;}
