JavaScript - Loading Rollover Images?
I have some rollover images on my website, and they don't switch until the page is finished loading.
Is this standard? Is there a way to have the rollovers work when the page is still in the process of loading all the images? Thanks Similar TutorialsHi I am currently doing a photography site. I would like to do a 'portfolio' page, but would like to pre-load the images so that they appear on-screen faster. Do I need to connect code to <body onload>? is there a way to after thye page load add an image. So maby loading it in the background and just showing it when you click a button?
Hi all I've been looking now for over a week on how create this http://instances.110mb.com/ effect when you hover over the ships on that page. I would be eternally grateful for any ideas how to replicate this effect. Thanks Rob Hello, I just created a new page topper for my website, and am new to javascript. I spent HOURS on designing all of the mouseover images that are on my website now, except there are spaces in between all of the images and I designed them to touch. You can see what I am talking about on my website he http://www.corporateavedesign.com I've tried everything in the code to get these images to touch. Can anyone help? Here is my code: Code: <SCRIPT LANGUAGE="JavaScript">

Please help if you can, I am desperate and my website looks crazy right now! THANKS!!! I'm trying to do some rollover images for a webpage I need to design, for class. I have them set up, and they work.. but the issue is that I set it up in such a way that the .js file is dynamic, and works for each page. You know, so that I don't actually have to specify the images within the .js file. The problem with THAT is that it doesn't automatically load the rollover version of each image, when the page loads.. so it's a bit sluggish. Here's my .js file Code: function swap_image(name,source) {
document.images[name].src=source;
var argv=swap_image.arguments;
if(argv[2] && argv[3] && document.getElementById) {
element=document.getElementById(argv[2]);
element.innerHTML=argv[3];
}
}
Here's how I have it in the HTML Code: <a href="gallery" onmouseover="swap_image('gallery','/images/galleryro.jpg')" onmouseout="swap_image('gallery','/images/gallery.jpg')">
<img style = "top:150px; left:100px;" border="0" id="gallery" src="/images/gallery.jpg"/> </a>
Is there anything I can do to force it to load the rollover image, without sacrificing my dynamic .js code? Hi Currently my website waits till all images are loaded up first: Code:
$(document).ready(function(){
* LOAD UP ALL THEM IMAGES FIRST... *
$(window).load(function() {
letsLoad();
fadingEffects();
});
However my website now has over 200 images on the website and now its taking way too long to load the images. My question's a 1. Is it possible to either load the site when its around 20% or even 50% loaded? OR 2. If its possible to give certain images a tag?? and when these images are loaded then the site loads? Heres a link to the site - must warn you need broadband and a high speed connection takes way to long to load. Takes me around 1minute 30seconds http://www.arcvizio.co.uk/ovoma/2/index.html Thanks Hi i have two images which are part of a rollover button that i want to have paused until the intro animation finishes. I have the javascript code but the rollover images are specified in the css. I just have the id to them in the html. I was wondering if anyone knew how to include the rollover files with the pausing javascript code. the files are profile.gif and profileover.gif. I tried to add the files to the preload part of the javascript but that didn't work. The website is www.creationindex.com/indextest.html thank you
Greetings, I am looking for either a JavaScript or Coldfusion solution to the following problem. First, there are over 60 million product photos so downloading and resizing the photos using Coldfusion would be very tedious. I would like the display an image within a 100 x 100 pixel container. If the height or width of the image is great than 100 pixels, the image should reduce in size to fit within the 100 x 100 pixel container. I want to avoid pixelation of the images as much as possible. All images are external and not on the local server so I only have an image URL. I would like to hide all images until they are resized appropriately. Does anybody know of a piece of javascript code that can do something similar to this? Sincerely, Travis Walters Hello. I've recently implemented this really cool jQuery preloader called queryLoader. When a visitor comes to my site they are fed all the important images for the entire site (it's a very small site). During that time queryLoader shows a percentage loading animation, and once all the images are loaded it wipes the screen & displays the website. I've placed another custom animation in the "page loading" div, and i want to make sure it loads first so that it is displayed while the rest of the images get downloaded. I've tried pre-loading with javascript as the very first script in my header, before jQuery or queryLoader get loaded, like this: Code: <script type="text/javascript">
pic1= new Image(250,300);
pic1.src="images/page_loading.gif";
</script>
<script type="text/javascript" src="scripts/jQuery.js"></script>
<script type="text/javascript" src="scripts/queryLoader.js"></script>
However, this doesn't seem to be that effective. When i clear browser cache and reload the page, the page_loading.gif sometimes doesn't appear until the site is almost completely loaded. Is there a more effective way to assure the page_loading.gif gets loaded before any other images? My site is jugtones.com if that helps in any way. Thanks for your time, -Scott Hello, I have develop a piece of code that when the user loads the html page it will load a local image but if the image doesn't exist it will load from a remote server. The question that remains is if it's possible to make an event in case the image is load locally? 1) HTML Page is load 2) If image doesn't exist locally reload from the server 3) If the image is load locally report back to the site Is the 3) possible? Code:
<html>
<head>
<title>test</title>
</head>
<body>
<script language = "javaScript">
var clouds = [];
var i = 0;
while(i <= 5) {
var cld = new Image();
cld.onload = function()
{
clouds.push(cld);
}
cld.src = "cloud.png";
i++;
}
document.write(clouds.length);
</script>
</body>
</html>
Where am I messing up clouds.length returns 0. Why? I know this is simple, but it will get more complex. I can search for the code, but I would like feedback as to what I'm doing wrong. This is more than likely going to be a multi stage question. More to come... ------ Also, I would like to say that this is my first post. Thanks in advance to those who reply. Hey guys, Lookin' for a little help, not sure if it can even be done? hopefully someone has the answer. I'm trying to design myself an online portfolio; here's what I got so far... http://www.gregorymstevens.com/testsite/site.html As you can see my navigation is represented by each bird on the tree (every bird is a link), when you rollver one of the green birds they turn white, however, I am looking to not only have the green bird rollver to white but ALSO have the "choose a" image on the bottom right change to the corresponding page. For instance, when the mouse rolls over a bird-- this image: will turn into this image: while maintaining the original "white bird" rollover. Hopefully I'm explaining this correctly -- Any help greatly appreciated! Hello all, I have the following code to load a new html page into the 'new content' div once the user scrolls to the bottom of the page. It all works fine. No problems, except I would like it to pause for a moment whilst it is loading, and show a loading box div at the bottom of the screen as it loads the new content, just to give some positive feedback for the user. So the new div would sit in a fixed position at 'bottom:0px;' and have a loading image inside it. Is this easy to do? I am new to javascript so bear with me Code: alreadyloading = false;
nextpage = 2;
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() == $(document).height()) {
if (alreadyloading == false) {
var url = "page"+nextpage+".html";
alreadyloading = true;
$.post(url, function(data) {
$('#newcontent').children().last().after(data);
alreadyloading = false;
nextpage++;
});
}
}
});
The 'new content' is a div which is at the bottom of the page and is where the new content loads to! Thank you very much I have a div in my HTML that that when rolled over reveals an image. I can't figure out how to place a random image from a set of 5 images to appear in the background of that div when it is rolled over again. Please help me! Okay so I am fairly new to Javascript and am having some difficulties getting this rollover to work. I've gotten this rollover code to work in multiple other pages and for some reason it just wont work for this page. The code is below, basically I have three buttons on the page that need to have a rollover effect to display an alternate image for each button, I started small to try and get just the first one to work and have not had any luck. Tried three different browsers, nothing. Any advice will be greatly appreciated. Code:

Hello, my first post here; and i am new to javascript i actually am just starting to learn the concept of javascript; and I am wondering.... if certain aspects of a website are made by using javascript such as the part on facebook "My Account"; where on click it opens a "window" with options. OR, on amazon where the menu items pop out on rollover;; can someone please tell me if they are acomplishing that by using javascript? thank you and i appreciate who ever is reading this. I'm having trouble with a 3-state rollover with rollClick staying active for a series of buttons. Each button reveals it's own content within the same page. Here's a working example of what I have. The roll in and out works fine at first, but after the second click the images start getting jumbled together. Something to do with the lastClick code at the bottom I think. HTML-side my button images get class="rollover" and a unique id. Code: window.onload = rolloverInit;
document.getElementsByClassName = function(cl) {
var retnode = [];
var myclass = new RegExp('\\b'+cl+'\\b');
var elem = this.getElementsByTagName('*');
for (var i = 0; i < elem.length; i++) {
var classes = elem[i].className;
if (myclass.test(classes)) retnode.push(elem[i]);
}
return retnode;
};
function rolloverInit(){
var rollOvers = document.getElementsByClassName("rollover");
for(var i=0; i<rollOvers.length; i++){
setupRollover(rollOvers[i]);
}
}
function setupRollover(thisImage){
//UP
thisImage.outImage = new Image();
thisImage.outImage.src = "images/" + thisImage.id + "1.gif";
thisImage.onerror = thisImage;
thisImage.onmouseout = rollOut;
//OVER
thisImage.clickImage = new Image();
thisImage.clickImage.src = "images/" + thisImage.id + "2.gif";
thisImage.onerror = rollOut;
thisImage.onmousedown = rollClick;
//DOWN
thisImage.overImage = new Image();
thisImage.overImage.src = "images/" + thisImage.id+"2.gif";
thisImage.onerror = rollOut;
thisImage.onmouseover = rollOver;
thisImage.onmouseup = rollOver;
}
function rollOver() {
this.src = this.overImage.src;
}
function rollOut() {
this.src = this.outImage.src;
}
function rollClick() {
if(lastClick){
lastClick.onmouseout = rollOut;
lastClick.src = this.outImage.src;
}
this.src = this.clickImage.src;
this.onmouseout = rollClick;
lastClick = this;
}
var lastClick = null;
What I'd also like, since these buttons act as tabs, is for the first button to already be in the rollClick active state on page load (since that button's content is already displayed by default). Is this possible? Thanks for any help you can provide! I have a small .png on my site. I want to view at 250% when I rollover it. Is there a way to have the 250% .png be centered vertically and horizontally where the 100% without making the 100% .png 250% bigger (ex. extra white space). Any recommendations for other ways? I am having trouble I can target two iframe windows at the same time using a Text Link, However I have not found a way to do this using a roll over image. Here is the Two codes I know. Can anyone help me please.... (roll over image) In the <head> <SCRIPT LANGUAGE="JavaScript"> <!-- Begin loadImage1 = new Image(); loadImage1.src = "http://www.midwestfishing.org/pics/01_info_blue.gif"; staticImage1 = new Image(); staticImage1.src = "http://www.midwestfishing.org/pics/01_info_black.gif"; ...........................................................
