I am sorry for asking a very minor thing but I feel a bit helpless in this one. I have integrated a pre-loader image at my page load in a very simple way
This is my Page link
HTML: (Div for loading Pre-loader image)
<div class="se-pre-con"></div>
Jquery to trigger the pre-loader on page load
$(window).load(function() {
// Animate loader off screen
$(".se-pre-con").fadeOut();
});
A bit of Styling . CSS
<style>
.no-js #loader { display: none; }
.js #loader { display: block; position: absolute; left: 100px; top: 0; }
.se-pre-con {
position: fixed;
left: 0px;
top: 0px;
width: 100%;
height: 100%;
z-index: 9999;
background: url('http://www.rybena.com.br:8080/RybenaRepository/resource/img/loading.gif') center no-repeat #fff;
}
Problem
When Page loads, it splashes before the Pre-loader image one time and then loads after the pre-loader image complete its effect. Theoretically, pre-loader should display before page load. I hope anyone of you can figure out where and what I did wrong?

I think your HTML isn't well formatted on the link you provided:
What I would do is make sure the HTML page has a structure similar to this:
<html>
<head>
<script>
</script>
</head>
<body>
<div class="se-pre-con"></div>
<div class="site-content"></div>
</body>
</html>
And inside your script tag have the following method:
$(window).load(function() {
$(".site-content").show(); //or fadeIn (what ever suits your needs)
$(".se-pre-con").fadeOut();
});
And in your css make sure you set
.site-content{
display: none;
}
EDIT: (To answer your question in comment- call loader at any time)
I would probably create a function like this:
function toggleLoader(show){
if(show == true){
$(".se-pre-con").show();
$(".site-content").fadeOut();
}
else{
$(".site-content").show();
$(".se-pre-con").fadeOut();
}
}
Then on window load you would call: toggleLoader(false),
When you make a request call: toggleLoader(true),
And when you receive a response call: toggleLoader(false).
page content is also visible on page load along with loader element so there no any sequence which content load first, but you can manger by following code, Suppose you have two div, one pre-loader div another site container div
<body>
<div class="se-pre-con"></div>
<div id="container" style="display: none;">
<!-- site content here -->
</div>
</body>
in container div add display: none style so site content cant't blink on page load.. and when page load then you can show container div, see below code
$(window).load(function() {
// Animate loader off screen
$("#container").show();
$(".se-pre-con").fadeOut();
});
Just gone thru your page link and noticed that display:none; was added to .se-pre-con as shown below. Please remove the display:none; property. It works buddy!
.se-pre-con {
position: fixed;
left: 0px;
top: 0px;
width: 100%;
height: 100%;
z-index: 9999;
background: url('http://www.rybena.com.br:8080/RybenaRepository/resource/img/loading.gif') center no-repeat #fff;
display: none;
}

I've created a full-screen image viewer as follows...
At the top of my <body> tag I have the following:
<div id="backdrop" class="hide"></div>
I then have some <img> tags that are toggled via JavaScript.
<img id="1" onClick="toggleSelect(1)" src="thumb.jpg" class="small" />
<img id="2" onClick="toggleSelect(2)" src="thumb.jpg" class="small" />
<img id="3" onClick="toggleSelect(3)" src="thumb.jpg" class="small" />
CSS:
#backdrop {
position: fixed;
width: 100%;
height: 100%;
background-color: #000;
z-index: 1000000;
}
.hide {
display: none;
}
.show {
display: block;
}
img.small {
cursor: pointer;
position: relative;
height: 300px;
width: auto;
z-index: 999999;
}
img.big {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 90%;
z-index: 1000001;
}
The images and the backdrop basically have their classes toggled:
<script type="text/javascript">
toggleSelect: function(index) {
if (images[index].selected)
{
$("#"+index).addClass('small');
$("#"+index).removeClass('big');
$("#backdrop").addClass('hide');
$("#backdrop").removeClass('show');
images[index].selected = false;
}
else {
$("#"+index).addClass('big');
$("#"+index).removeClass('small');
$("#backdrop").addClass('show');
$("#backdrop").removeClass('hide');
images[index].selected = true;
}
}
</script>
This all works well and good as you can see here:
However, if I scroll down and then toggle the image, you can see it's problematic:
Given this situation, is there any easy or convenient way to get the image to go fullscreen (90% height as set in the CSS) regardless of my current scroll position?
Thanks in advance for any help.
Try by setting overflow hidden to body, when image is fullscreen:
<script type="text/javascript">
toggleSelect: function(index) {
if (images[index].selected)
{
$("#"+index).addClass('small');
$("#"+index).removeClass('big');
$("#backdrop").addClass('hide');
$("#backdrop").removeClass('show');
$('html, body').css({overflow: 'auto'});
images[index].selected = false;
}
else {
$("#"+index).addClass('big');
$("#"+index).removeClass('small');
$("#backdrop").addClass('show');
$("#backdrop").removeClass('hide');
$('html, body').css({overflow: 'hidden'});
images[index].selected = true;
}
}
</script>
I am trying to make this effect on a project
http://www.cera-groupecera.com/en/
like this page the footer is hidden and appears as you scroll.
The page is wrapped in a page-content element and the footer is fixed to the bottom z-indexed 0
what happens is as you reach the end of the window the page -content margin rises as you scroll.
I can't really find a way to do it with j query
Here is an example,you just position it on the bottom of the page or in any other place you want it to stay,to hide it you can use z-index=-1;
//<br><br><br><br><br><br><br><br><br>
<h2><code>fixed</code></h2>
<div class="fixed"><div class="expand"></div></div>
<br><br><br><br><br><br><br><br>
CSS
#import "compass/css3";
h2 {
text-align: center;
margin-top: 48px;
}
div {
height: 200px;
width: 50%;
max-width: 600px;
margin: 32px auto;
overflow-x: hidden;
// overflow-y: scroll;
}
.fixed {
background: url('http://lorempixel.com/600/200/animals');
background-attachment: fixed;
overflow: hidden;
}
.expand {
height: 400px;
width: 100%;
}
https://jsfiddle.net/cu01m218/
I did one example for you.
$(function(){
calcFooter();
function calcFooter () {
var footer = $('.footer').height();
var mainContent = $('.main-content');
mainContent.css('margin-bottom', footer);
}
$(window).resize(calcFooter);
});
body {
margin: 0;
}
.main-content {
position: relative;
z-index: 100;
height: 100vh;
background-color: grey;
}
.footer {
position: fixed;
bottom: 0;
left: 0;
z-index: 10;
height: 200px;
width: 100%;
background-color: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div class="wrapper">
<div class="main-content" style="margin-bottom: 200px;">
<h1>This is main content.</h1>
<p>Scroll down to reveal footer!</p>
</div>
<div class="footer">
<p>This footer.</p>
</div>
</div>
Let's say that this element which appears at the bottom is footer tag.
In this case it will be something like this:
html:
<footer></footer>
in your css:
footer {
position: fixed;
bottom: 0;
display: none;
}
Then you have to add a class which will make footer appear
.active {
display: block;
}
and your jquery will be something like this:
$(window).on('scroll', function () {
if ($(this).scrollTop() > 50) {
if (!$(footer).hasClass('active')) {
$(footer).addClass('active');
}
} else {
if ($(footer).hasClass('active')) {
$(footer).removeClass('active');
}
}
});
I searched for hours trying to find a solution for creating a body background image clickable.
I managed to find some similar questions/answers here on stackoverflow but I don't know how to apply them.
So far I think that the code below might help but I cannot seem to understand how to use it on my website.
$('body').click(function(e){
if (e.target === this) {
window.location = "link.html"
}
});
Can someone please explain how can I have this working on 007soccerpicks.com? I need the body background image clickable except for the <div id="container"> which is the content area of the website.
Thank you very much!
The script you have setup will click the entire document if wrapped inside the body element. One way to get around this is to use a fixed element in the background with the body logic in another wrapper.
<body>
<div class="body-clickable"></div>
<div class="main-content">
</div>
</body>
<style>
.body-clickable
{
position: fixed;
top: 0;
left: 0;
z-index: 1;
height: 100%;
width: 100%;
background-image: url('image.png');
}
.main-content {
margin: 0 auto;
width: 1000px;
top: 0;
left: 0;
position: relative;
z-index: 2;
}
</style>
<script>
$('.body-clickable').click(function(e){
if (e.target === this) {
window.location = "link.html"
}
});
</script>
You could also avoid using a script and actually just make the 'body-clickable' a link.

Within Sitefinity CMS, I am using a gallery script that seems to be compiled in the backend files. In other words, I can't access nor change the sourcecode.
The gallery works as it should, but I would like to add a lightbox to it. So I started using 'wrapAll' combined with on load. This works on the very first image, but as soon as the next image is loaded dynamically (in other words, the image and surrounding tags are being replaced), it stops working.
I am stuck. Anyone any idea?
My code:
$(window).on("load", function () {
var i = 0;
$(".galleria-images .galleria-image img").each(function () {
i++;
//alert(i);
var lightboximg = $(this).attr("src");
$(this).wrap("<a href=" + lightboximg + " class='fancybox'></a>");
});
$(".fancybox").fancybox();
})
I also tried to just add fancybox() to the structure, but that works once as well.
The generated HTML (as it should):
<div style="position: relative; top: 0px; left: 0px; width: 100%; height: 100%;" class="galleria-images">
<div style="overflow: hidden; position: absolute; top: 0px; left: 0px; transition: none 0s ease 0s ; opacity: 0; z-index: 0;" class="galleria-image"><div style="position: absolute; top: 0px; left: 0px; right: 0px; bottom: 0px; z-index: 2;" class="galleria-layer"></div>
<div style="overflow: hidden; position: absolute; top: 0px; left: 0px; z-index: 4; background: rgb(0, 0, 0) none repeat scroll 0% 0%; display: none;" class="galleria-frame">
</div>
</div>
<div style="overflow: hidden; position: absolute; top: 0px; left: 0px; opacity: 1; width: 563px; height: 340px; transition: none 0s ease 0s ; z-index: 1;" class="galleria-image"><div style="position: absolute; top: 0px; left: 0px; right: 0px; bottom: 0px; z-index: 2; display: none; width: 563px; height: 352px;" class="galleria-layer">
</div>
<div style="overflow: hidden; position: absolute; top: 0px; left: 0px; z-index: 4; background: rgb(0, 0, 0) none repeat scroll 0% 0%; display: none;" class="galleria-frame">
</div>
<a href="/images/default-source/scholen/adm/administratief-en-juridisch-44.jpg?sfvrsn=2" class="fancybox">
<img src="/images/default-source/scholen/adm/administratief-en-juridisch-44.jpg?sfvrsn=2" style="display: block; opacity: 1; min-width: 0px; min-height: 0px; max-width: none; max-height: none; transform: translate3d(0px, 0px, 0px); width: 544px; height: 340px; position: absolute; top: -6px; left: 0px;" height="340" width="544"></a>
</div>
</div>
The next image looks the same, except the image isn't wrapped.
update
Eventually solved it by killing Galleria and starting it over again using my own options. The excerpt is:
Galleria.configure({
extend: function (options) {
Galleria.log(this) // the gallery instance
Galleria.log(options) // the gallery options
// listen to when an image is shown
this.bind('image', function (e) {
Galleria.log(e) // the event object may contain custom objects, in this case the main image
Galleria.log(e.imageTarget) // the current image
lightboximg = jQuery(e.imageTarget).attr("src");
jQuery(e.imageTarget).addClass('test');
jQuery(e.imageTarget).wrap("<a href=" + lightboximg + " class='fancybox'></a>");
$(".fancybox").fancybox();
});
}
});
The problem is that "load" event triggers only once. That's why you can see only one image wrapped.
Here is a easy way to do it:
HTML
<div id="container">
Hello World
</div>
JS
(function() {
setInterval(function(){
$("#container").append('<div class="item new">New Item</div>');
}, 3000);
setInterval(function() {
$('.item').css('color', 'red');
$('.item').removeClass('new');
}, 100);
})();
Fiddle
Downside of this approach is unnecessary load on page, so if you need performance, take a look at:Determining if a HTML element has been added to the DOM dynamically
The third option, and the best on my opinion is to trigger custom event when image added, but for this you will need to change code, which actually responsible for adding images to the page:
$(document).trigger('imageAdded');
$(document).on('imageAdded', function() {....})
I have a div and within that div is an image, and layed on top of those is 2 divs which have jquery hover attached to them (same issue with onmouseover though, so not jquery).
Problem is when the image is loaded, even though the divs are layed on top of the image they won't fire because the image is always on top (even though it isn't actually, and i've tried putting it lower down on z-index but it didn't help).
jquery:
<script type="text/javascript">
$(document).ready(function () {
$(this).find("#largeInset").find(".content").css("width","0");
$("#largeInset").hover (function() {
$(this).find(".content").animate({width: '100%'}, 500, function() {});
},
function() {
$(this).find(".content").animate({width: '0'}, 500, function() {});
});
$(this).find("#largeArticles").find(".content").css("width","0");
$("#largeArticles").hover (function() {
$(this).find(".content").animate({width: '40%'}, 500, function() {});
},
function() {
$(this).find(".content").animate({width: '0'}, 500, function() {});
});
});
</script>
Html:
<div class="largeContent">
<img src="<?php echo $img[0]; ?>" border="0" alt="" title="" />
<div id="largeInset">
<div class="content">
[content]
</div>
</div>
<div id="largeArticles">
<div class="content">
<ul> (loop fills this)
<li>
[content]
</li>
</ul>
</div>
<br style="clear: both;" />
</div>
</div>
Is this a known IE bug that I just haven't come accross before? Or is there a bug in my code? When filled with content the largeInset and largeArticles divs should fire on hover and slide out across the image, works in chrome but not IE as IE seems to select the image on top of the divs even though they are actually below it (Would work fine if the image didn't load).
Any ideas? Hopefully I made sense.
CSS:
.articles { position: relative; width: 100%; padding: 0; float: left; background-color: #fff; }
.large { margin: 0 0 10px; border: 0px solid #000; min-height: 200px; }
.large img { max-width: 100%; min-width: 100%; min-height: 350px; z-index: -1; }
.largeContent { z-index: 99; position: absolute; top: 0; width: 100%; height: 100%; }
.filler { width: 100%; height: 100%; }
#largeInset { position: absolute; top: 0; right: 0; min-height: 100%; width: 25%; color: #fff; }
#largeInset .head { padding: 10px 0; }
#largeInset p { font-size: 0.9em; margin: 5px 10px; }
#largeInset .content { overflow: hidden; position: absolute; top:0; background-color: #000; right: 0; color: #fff; }
#largeArticles { position: absolute; top: 0; left: 0; width: 25%; min-height: 100%; }
#largeArticles .content { overflow: hidden; position: absolute; top: 0; left: 0; width: 40%; background-color: #000; }
I've solved this for now by adding content to the divs. IE will only fire when you mouseover the content in the div (maybe because position is absolute?). I added a transparent 1px image to the divs, but stretched to 100% x 100%, so you hover over the image and it will fire.
This seems a bit hacked together though
