Reload a DIV on click of another DIV

I have a div called masterdiv, inside this div there are 3 other div div1, div2, and div3,
This is the html for these html:
<div id="masterdiv" class="masterdivclass">
<div id="div1"><img class="div1class" src="image1.jpg" id="div1id" /></div>
<div id="div2"><img class="div2class" src="image2.jpg" id="div2id" /></div>
<div id="div3"><img class="div3class" src="image3.jpg" id="div3id" /></div>
</div>
I also have another div:
<div id=”reload”><img src="reload.png" width="200" height="70" onclick=loadDIV();></div>
What I’m trying to do is to reload the masterdiv div whenever the reload div is clicked on. Hiding and then showing the div isn’t enough as I need the content to be reloaded when the refresh div is clicked on. I don’t want to reload the entire page, just the masterdiv which contains the 3 other div. But I’m not certain this is possible.
I’m trying to do it with this Javascript function:
<script type="text/javascript">
function loadDiv(){
$("<div id="masterdiv" class="masterdivclass">
<div id="div1"><img class="div1class" src="image1.jpg" id="div1id" /></div>
<div id="div2"><img class="div2class" src="image2.jpg" id="div2id" /></div>
<div id="div3"><img class="div3class" src="image3.jpg" id="div3id" /></div>
</div>").appendTo("body");
}
</script>
This isn’t working, I think maybe I'm going about this in the wrong way? Maybe I’m missing something very simple here? I’d really appreciate any help with this, thank you in advance!
UPDATE
After reconsidering my project's requirements, I need to change part of my question, I now need to randomise the images displayed in the divs, and have a new random image load every time the reload div is clicked on. I also need to remove each class that’s currently in each of the three divs and then reattach the same classes to the divs (if I don’t remove and reattach the classes then the divs just display the plain images without any class/effect applied to them, it seems like I need to reload the class every time I load an image into a div in order for the class/effect to be applied successfully).
I have 5 images, and I’m using each div’s id tag to attach a random image to each div.
First I’m assigning the 5 different images to 5 different ids:
<script>
document.getElementById('sample1').src="images/00001.jpg";
document.getElementById('sample2').src="images/00002.jpg";
document.getElementById('sample3').src="images/00003.jpg";
document.getElementById('sample4').src="images/00004.jpg";
document.getElementById('sample5').src="images/00005.jpg";
</script>
And then I’m trying to use the following Javascript to load a randomised id (and its assigned image) to each of the 3 divs when the reload div is clicked:
<script>
$(function() {
$('#reload').on('click',function(){
$("#masterdiv").find("div[id^='div']").each(function(index){
//First, remove and reattach classes “div1class”, “div2class” and “div3class”
//from “easyDIV”, “mediumDIV” and “hardDIV” respectively:
$(“#easyDIV”).removeClass('div1class');
$(“#easyDIV”).addClass('div1class');
$(“#mediumDIV”).removeClass('div2class');
$(“#mediumDIV”).addClass('div2class');
$(“#hardDIV”).removeClass('div3class');
$(“#hardDIV”).addClass('div3class');
//Get a random number between 1 and 5, then attach it to “sample”,
//so that the result will be either “sample1”, “sample2”, “sample3”, “sample4” or “sample5”,
//call this variable “variablesample”:
var num = Math.floor(Math.random() * 5 + 1);
variablesample = "sample" +num;
//Attach this randomised id to all three divs using “variablesample”:
jQuery(this).prev("easyDIV").attr("id",variablesample);
jQuery(this).prev("mediumDIV").attr("id",variablesample);
jQuery(this).prev("hardDIV").attr("id",variablesample);
});
var p = $("#masterdiv").parent();
var el = $("#masterdiv").detach();
p.append(el);
});
});
</script>
I’m trying to make it so that all 3 divs will show the same randomised picture (that’s why they’re all sharing the variable “variablesample”), and each div will reload its own class/effect (div1class, div2class and div3class) but it’s not working. I’m not sure if it’s correct to use jQuery inside a Javascript function, or if my syntax for updating the ids of the divs is incorrect.
Perhaps my logic to solving this problem is all wrong? I’d really appreciate any more help with this problem. Thanks again in advance!

Original question was edited many times, so here is the correct answer for the latest edit. Answer to the question; "How to use random image, but same image on all 3, and 3 class on/off switching":
$(function() {
var imageArray = [
'https://via.placeholder.com/40x40',
'https://via.placeholder.com/80x40',
'https://via.placeholder.com/120x40',
'https://via.placeholder.com/160x40',
'https://via.placeholder.com/200x40'];
reloadImages(imageArray);
$('#reload').on('click',function(){
$( "#masterdiv img[id^='div']" ).each(function(index){
$(this).removeClass("div"+(index+1)+"class");
$(this).fadeOut( "slow", function() {
if(index==0) {
reloadImages(imageArray);
}
$(this).addClass("div"+(index+1)+"class");
$(this).fadeIn();
});
});
});
});
function shuffleArray(array) {
for (var i = array.length - 1; i > 0; i--) {
var j = Math.floor(Math.random() * (i + 1));
var temp = array[i];
array[i] = array[j];
array[j] = temp;
}
return array;
}
function reloadImages(array){
shuffleArray(array);
for(var i=0;i<3;i++){
// places the first image into all divs, change 0 to i if you want different images in each div
document.getElementById('div'+(i+1)+'id').src=array[0];
}
}
.div1class {

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id='reload'>Click here</div>

<div id="div3">

Line breaks and un-escaped quotes are why the functions is not working.
function loadDiv(){
$('#masterdiv').remove();
$("<div id='masterdiv' class='masterdivclass'><div id='div1'><img class='div1class' src='image1.jpg' id='div1id' /></div><div id='div2'><img class='div2class' src='image2.jpg' id='div2id' /></div><div id='div3'><img class='div3class' src='image3.jpg' id='div3id' /></div></div>").appendTo("body");
}

try:
function loadDiv(){
$("#masterdiv").load(location.href + " #masterdiv");
}
Here's the code pen demo:
http://codepen.io/anon/pen/xwgRWm

If content of container is not being changed dynamically then there is no point reloading it. appendTo wiil append DOM in existing DOM structure, you will need html() here which will replace the content inside container. Also note you had typo here onclick=loadDiv();
HTML:
<div id="masterdiv" class="masterdivclass">
<div id="div1"><img class="div1class" src="image1.jpg" id="div1id"/></div>
<div id="div2"><img class="div2class" src="image2.jpg" id="div2id"/></div>
<div id="div3"><img class="div3class" src="image3.jpg" id="div3id"/></div>
</div>
<div id="reload"><img src="reload.png" width="200" height="70" onclick=loadDiv();></div>
JS:
function loadDiv() {
$("#masterdiv").html('<div id="div1"><img class="div1class" src="image1.jpg" id="div1id" /></div>\
<div id="div2"><img class="div2class" src="image2.jpg" id="div2id" /></div>\
<div id="div3"><img class="div3class" src="image3.jpg" id="div3id" /></div>');
}

How make a popup work

I am trying to develop a popup feature when you click on an Image the image opens up as a popup. Here is the example
http://soumghosh.com/otherProjects/natalierosscms/175-2/
Click on the first image and close it. Then click on the second image. The images are repeating. Any ideas what I am doing wrong? For some reason I am not able to post code here.
JavaScript:
$('.alignnone').click(function(){
$('.overlay').appendTo('body');
$('.overlay').show();
var popImage = $('.projectContainer').show();
var thumbHolder = $(this).parent();
thumbHolder.css('position', 'relative');
$(this).clone().appendTo('.projectContainer');
var cssAtrOne = {
padding:'10px',
width:'110%'
};
popImage.appendTo(thumbHolder).css(cssAtrOne);
});
$('.closeButton').click(function(){
$('.overlay').hide();
$('.projectContainer').hide();
});
HTML:
<!-- clickable image -->
<img src="http://soumghosh.com/otherProjects/natalierosscms/wp-content/uploads/2013/03/T1Main.jpg" alt="T1Main" width="559" height="745" class="alignnone size-full wp-image-181">
<!-- popup -->
<div class="projectContainer" style="padding: 10px; width: 110%; display: block;">
<img class="closeButton" src="/otherProjects/natalierosscms/wp-content/themes/twentyeleven/images/closeButton.png">
</div>

You have this:
$(this).clone().appendTo('.projectContainer');
You're appending the image to the projectContainer without clearing the projectContainer first (So images just continue to build up each time). So what you'll need to do is clear out the previous images, then insert the new one.
But inside projectContainer is your close button, which makes things a wee bit tricker. There are many ways to work around this issue, but a straight-forward solution would be to introduce another <div>, imageContainer inside projectContainer:
HTML:
<div class="projectContainer" style="display: none; padding: 10px; width: 110%;">
<img class="closeButton" src="/otherProjects/natalierosscms/wp-content/themes/twentyeleven/images/closeButton.png">
<div class="imageContainer"></div>
</div>
Then modify your JS:
Change JS:
//REPLACE the contents of imageContainer, not append to it.
//$(this).clone().appendTo('.projectContainer');
$('.projectContainer > .imageContainer').html($(this).clone());
Something to that effect should work.

Background Image Rotator with jQuery?

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);
});
};

Create a falling div (that works in IE)

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>

Get image src from a image in a slideshow

I've been looking around much today and spend a few hours trying to get something done. For a client I am creating a slideshow with a lightbox when clicked on an image. The slideshow and lightbox both work, but I don't get the right image in the lightbox yet.
This is the code that loads the slideshow and when clicked on an image opens the lightbox.
(The images for the slideshow get loaded by a php script and turned into a Javascript array)
<script type="text/javascript">
var curimg=0;
function rotateimages(){
document.getElementById("slideshow").setAttribute("src", "images/"+galleryarray[curimg]);
curimg=(curimg<galleryarray.length-1)? curimg+1 : 0;
}
window.onload = function(){
setInterval("rotateimages()", 1000);
}
</script>
<div style="width: 170px; height: 160px">
<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style. display='block'">
<img id="slideshow" src="" />
</a>
<div id="light" class="white_content">
<img id="lightImg" src="" />
<script>
var image = document.getElementById("slideshow").src;
document.getElementById("lightImg").setAttribute("src", image);
</script>
I now try to create a variable named "image"and let this contain the src of the current image in the slideshow. So I can load this to the image in the lightbox.
Hopefully some one can give me some usefull tips. I am pretty new in the Javascript language.
The script for the slideshow came from: http://www.javascriptkit.com/javatutors/externalphp2.shtml

These days there really is no excuse for using obtrusive Javascript (Stuff inside your HTML attributes, ideally it should be in an external file. http://en.wikipedia.org/wiki/Unobtrusive_JavaScript).
I have done you the favour of cleaning up your code a bit, and changed it where you seemed to be going wrong. As DotNetter has already pointed out it would be sensible to use jQuery in this instance, as it really does simplify things. However, I'm going to assume that for some reason you want it in plain js. Below is a simplification of the code that you posted with the correct change.
<style type="text/css">
.wrapper {
width: 170px;
height: 160px;
}
</style>
<script type="text/javascript">
var curimg=0;
function rotateimages(){
document.getElementById("slideshow").setAttribute("src", "images/" + galleryarray[curimg]);
curimg=(curimg<galleryarray.length-1)? curimg+1 : 0;
}
window.onload = function(){
setInterval("rotateimages()", 1000);
document.getElementById("slideshow").onclick = function () {
var imageSrc = document.getElementById("slideshow").src;
document.getElementById("lightImg").setAttribute("src", imageSrc);
document.getElementById('light').style.display = 'block';
document.getElementById('fade').style.display = 'block';
}
}
</script>
<div class='wrapper'>
<img id="slideshow" src="" />
<div id="light" class="white_content">
<img id="lightImg" src="" />
</div>
</div>
Before, you were getting the src of the current image when the page loaded, you need to be getting the src of the image when the user clicks on the
