JavaScript - Image Fade In Onload
I've been looking for a way to fade a selection of images in on load while keeping their background present until they fade in. similar to whats been used on this site:
http://inventorystudio.co.uk/ thought this would be relatively simple but seems to be harder than i expected. any suggestions? Similar Tutorialshello, I am trying to get the page to fade in when it loads.. instead of using the microsoft enterpage metahead value.. here is the code I am trying, but no luck <html> <head> <SCRIPT LANGUAGE="JavaScript"> function fadeInPage() { if (document.getElementById("fadeDiv").filters.alpha.opacity < 100){ document.getElementById("fadeDiv").filters.alpha.opacity += 10; eval('setTimeout("fadeInPage()",100)'); } else{ document.getElementById('fadeDiv').style.visibility = "visable" } } </script> </head> <body onLoad="fadeinpage()"> <DIV ID="fadeDiv" style="visibility:hidden"> your page code goes here </DIV> </body> </html> This is a really awesome script that I'm sure all of you can put to use if you haven't yet heard of it. However, I'm trying to get it to fade a background image on my css styled navigation for my a:hover. Here is the script with a little simple tutorial on how to set it up: http://bavotasan.com/tutorials/creat...r-fade-effect/ My only other knowledge is in PHP, so after about 2 hours of fail in this client-side language, I decided it was about time I should post where some experienced people can help. I really appreciate all time you spend on this, and don't think it will take a moderate Javascript programmer very long. This is the link to my site so far: http://matt.mw/help-request You can see the script working as it is on my little yellow MW logo on the right side of the navigation. So in my scenario, I am looking to fade button.png to button-hover.png (both repeating on the x axis). Any ideas? I have this code... I want to be able to make each image fade from one to the other. Like this... http://www.dynamicdrive.com/dynamici...nslideshow.htm Is there a way to do that with this code? Code:
<script type="text/javascript">
// Simple Javascript Time based Image Swap
var Pics = new Array();
var counter = 0;
// Use this section to change the image paths
function LoadImages()
{
Pics[1] = new Image();
Pics[1].src = "images/pic1.jpg";
Pics[2] = new Image();
Pics[2].src = "images/pic2.jpg";
Pics[3] = new Image();
Pics[3].src = "images/pic3.jpg";
Pics[4] = new Image();
Pics[4].src = "images/pic4.jpg";
Pics[5] = new Image();
Pics[5].src = "images/pic5.jpg";
Pics[6] = new Image();
Pics[6].src = "images/pic6.jpg";
Pics[7] = new Image();
Pics[7].src = "images/pic7.jpg";
Pics[8] = new Image();
Pics[8].src = "images/pic8.jpg";
Pics[9] = new Image();
Pics[9].src = "images/pic9.jpg";
Pics[10] = new Image();
Pics[10].src = "images/pic10.jpg";
Pics[11] = new Image();
Pics[11].src = "images/pic11.jpg";
Pics[12] = new Image();
Pics[12].src = "images/pic12.jpg";
Pics[13] = new Image();
Pics[13].src = "images/pic13.jpg";
Pics[14] = new Image();
Pics[14].src = "images/pic14.jpg";
Pics[15] = new Image();
Pics[15].src = "images/pic15.jpg";
Pics[16] = new Image();
Pics[16].src = "images/pic16.jpg";
Pics[17] = new Image();
Pics[17].src = "images/pic17.jpg";
document.pic1.src = Pics[1].src;
}
//Time in miliseconds
function timedImage()
{
counter ++
if (counter > 17) {
counter = 1;
}
document.pic1.src = Pics[counter].src;
t=setTimeout("timedImage()",5000);
}
</script>
Dear all, I have been trying to replicate a cool javascript effect that appears here. See the funky images fading in when hovering with mouse? I want that ;-) By using Firebug I think I have narrowed down the code needed to: Code: <div id="main" class="clearafter">
<div class="inner clearafter">
<div class="columns clearafter">
<div class="project hovers column" style="border-color: rgb(255, 255, 255); cursor: pointer; background-color: rgb(255, 255, 255);">
<a href="http://mountfolly.co.uk" class="image">
<img width="274" height="137" alt="project" src="/images/41_project.jpg" class="screenshot">
<img width="274" height="137" alt="project" src="/images/7_project.jpg" class="text" style="opacity: 0; display: inline;">
</a>
<h3>Text and titles etc...</h3>
<p>etc etc etc...</p>
</div>
<div style="border-color: rgb(255, 255, 255); cursor: pointer; background-color: rgb(255, 255, 255);" class="project hovers column"></div>
</div>
</div>
</div>
<script type="text/javascript" src="/javascript/global.js"></script>
and this (which I put into a javascript file called global.js): Code: /* project listings */
// to deal with IEs opacity idiocy
$(function() {
$('.project.hovers .text').css({opacity: 0}).show();
$('.project.hovers').css({cursor: 'pointer'}).click(function() {
location.href = $('h3 > a', this).attr('href');
});
});
$('.project.hovers').hover(
function () {
$('.text',this).stop().fadeTo('100',1);
$(this).stop().animate({borderTopColor: '#E9E9E9', borderRightColor: '#E9E9E9', borderBottomColor: '#E9E9E9', borderLeftColor: '#E9E9E9', backgroundColor: '#EEE' }, 100)
},
function () {
$('.text',this).stop().fadeTo(1000,0);
$(this).stop().animate({borderTopColor: '#FFF', borderRightColor: '#FFF', borderBottomColor: '#FFF', borderLeftColor: '#FFF', backgroundColor: '#FFF' }, 1000)
}
);
But when I re-create the files (index.html, global.js, and replacement images) all I get is this. No hover effect... Any ideas what is missing? Would appreciate some help. Thanks, Wysiwyger PS: If you fancy a laugh, check these out Hi, I'm building a website which uses javascript to cycle through and fade images in the header portion of each web page. The javascipt os located in an external file and called via the master page. Here is the code in the content.js file which specifies where the images are located: Code: // create array of images
var CyclingImages = new Array("header/images/tankimage1.gif",
"header/images/tankimage2.gif",
"header/images/tankimage3.gif",
"header/images/tankimage4.gif")
Here is the code in the master page which finds the javascript: Code: <script language="javascript" src="<%= Page.ResolveUrl("~/content/content.js") %>" type="text/javascript"></script>
Here is the function call in the masterpage to fade and cycle the images: Code: <body onload="FadeAndCycleImages()"> Here is the code in the masterpage which references the cycling images: Code: <span class="fadingimages">
<img src="<%= Page.ResolveUrl("header/images/tankimage1.gif") %>" width="142" height="124" title="" alt="" name="cyclingimage" />
</span>
Each webpage loads the masterpage. If the webpage is located at the root of the project, the cycle and fade functionality works great. When I start to place some of the webpages in separate folders - which I need to do - the cycling and fading functionality breaks down, meaning the images cannot be found. The image place holder is there with the standard red "x" in the upper left. I have done a lot of research and tried many approaches to try to resolve this issue, but with no success. The root of the problem seems to lie in the fact that I cannot apply Page.ResolveUrl within the content.js file. Any suggestions would be greatly appreciated. Thank you, petela Hi everyone. I'm brand new to this forum and in need of some help. If you've got a free minute and are interested in helping the clueless I've got one for you. I'm trying to form a script and the appropriate calls to fade-in some text on the event of an image mouseover. Here is what I'm working with: Code: <html>
<head>
<script type="text/javascript">
function setOpacity(level) {
element.style.opacity = level;
element.style.filter = "alpha(opacity=" + (level * 100) + ");";
}
var duration = 1000;
var steps = 20;
var delay = 5000;
function fadeIn() {
for (i = 0; i <= 1; i += (1 / steps)) {
setOpacity(" + i + "), i * duration;
}
}
</script>
</head>
<body>
<p id="text" style="filter:alpha(opacity=0);opacity:0.5">
This is the text.
</p>
<img name="image" src="pic.jpg" onmouseover="javascript:fadeIn(document.getElementById('text'))" />
</body>
</html>
I know there are problems with this. It looks wonky to me and I don't even know what I'm doing. It's a mashup of some code I found somewhere and my own bad guesses at how to fill in the gaps. Any tips on how I can bring this together? Thanks so much for reading this far. I appreciate your time. Hi! I'm wondering if somebody here could help me please. I'm trying to develope the image slideshow using PHP and JavaScript. The idea is that the PHP file gets random images from the folder, i'm using session to prevent repeating the same image and then JavaScript generates the fade slideshow using that PHP file. I've come up with the solution to use two img tags in the HTML page, so JavaScript then swap them around and play with opacity, but unfortunately couldn't make it work. Everything I have tried in JavaScript didn't work properly. I'd be grateful for any help and advice guys. Thank you. My PHP code: PHP Code: <?php class images { var $images = Array(); var $imgDir = 'images/'; function getImages() { $images = Array(); if ($dir = opendir($this->imgDir)) { while(($file = readdir($dir)) !== false) { if(preg_match('#(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)#i', $file)) $images[] = $file; } closedir($dir); } return $images; } function getNextImage() { if (($images = $this->getImages()) !== false) { session_start(); if (!isset($_SESSION['image'], $images[$_SESSION['image']])) { $index = mt_rand(0, count($images)-1); } else { $index = $_SESSION['image'] == count($images)-1 ? 0 : $_SESSION['image']+1; } $_SESSION['image'] = $index; return $images[$index]; } return false; } function outputImage() { if (($file = $this->getNextImage()) !== false) { header('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1 header('Expires: Wed, 9 Dec 1981 07:00:00 GMT'); // Date in the past header('Content-type: image/jpg'); readfile($this->imgDir.$file); exit(); } } } $img = new images(); $img->outputImage(); ?> My HTML page: Code: <html> <head> <title>Images</title> <link rel="stylesheet" type="text/css" href="css/style.css" /> <script type="text/javascript" src="javascript/slideshow2.js" language="javascript"></script> </head> <body onload="startSlideShow();"> <h1>Images</h1> <div id="imageWrap"> <div id="images"> <img id="sampleImgFade" src="images.php" alt="images" style="filter:progid:DXImageTransform.Microsoft.alpha(opacity=0);-moz-opacity:0;-khtml-opacity:0;" width="800" height="600" onload="coverLoaded(this);" /> <img id="sampleImg" src="images.php" width="800" height="600" alt="images" onload="mainLoaded();" /> </div> </div> </body> </html> CSS code: Code: #imageWrap {

I've been trying to figure this out for days.. I just found a script that Old Pedant made which is close to what i need: http://www.clearviewarts.com/fadeBigDemo.html But two concerns: 1. how can i have it so when i click the thumbnail, it fades in a different image (rather than just a larger version of the thumbnail)? 2. how can i have it fade in and out from simply hovering over the thumbnail (rather than clicking it)? Your help would be greatly appreciated.. Hello, I'm learning javascript, and was wondering if it was Possible to have buttons/links that you click, the whole page fades out, and then fade's in, with different stuff. here are my ideas for just changing the stuff Text: 1. having a javascript src file to start, and then when the button is clicked, that is formatted to white, the text layer is moved down, and a new javascript file is loaded? 2.variables? any help would be appreciated! Thanks, Cookies, whatever this forum gives out, you may receive! Hi everyone, I'm new on this forum. I really need help in coding an part of my website. I want to make the logo background image fade to another background image on hover. Here is the code I have until now: Code: #logo
{margin-top:0px;
margin-bottom:0px;
margin-left:auto;
margin-right:auto;
width:600px;
height:515px;}
#logo h1
{display:block;
background:url(img/logo.jpg) no-repeat;
width:600px;
height:515px;
text-indent:-10000px;
margin:0px;}
#logo h1 a
{display:block;
width:100%;
height:100%;}
#logo h1 a:hover
{background:url(img/logo.jpg) no-repeat 0px -515px;}
I want the background:url(img/logo.jpg) no-repeat; to fade to {background:url(img/logo.jpg) no-repeat 0px -515px;}. I haven't found any tutorial which explains how to do that properly. I'd be really greatful if you could help me. Thank you very much, Alex Hello and thanks for the help. I'm no expert by any means, and I have no idea what the problem could be. Internet Explorer crops my images on my image fade, but Chrome and Safari view it just fine. the website is www.pisanchynproductions.com If you open it in IE and Chrome you can see Chrome shows image fadeshow fine, and IE crops the images.

I wish i knew more so I could realized how dumb this question was. Hello Can anyone help with the following problem On the following page http://www.stroudskittles.co.uk/signingon.html I have a Body onload event (to load the chained Menu) and a windows.onload event (to load the IFrame Ticker) If I open the page in Internet explorer both scripts function; however in Firefox I'm having problems. The Chained Menu works, however the IFrame Ticker does not display. Both events ahave ben placed on the boady tag. Can anyone advise how I can get both to display in Firefox Can anyone I've got a <ul> w/ 6 <li> items and CSS to make them 104x228 side blocks, which hold 2 images, one on top of the other. The 6 rows of images look like this: X X X X X X X X X X This is what I want: The top row of images to be opacity:0 (or hidden), and then when you mouseover the bottom images, the top images come to 100 opacity. When you mouseout, the opacity is back to 0. Here's the HTML and CSS: Code: <ul class="carz"> <li><img src="img/impreza2.jpg" class="imgtophidden"/><img src="img/impreza.jpg" /></li> <li><img src="img/wrx.jpg" class="imgtophidden"/><img src="img/wrx.jpg" /></li> <li><img src="img/legacy2.jpg" class="imgtophidden"/><img src="img/legacy.jpg" />/li> <li><img src="img/outback2.jpg" class="imgtophidden"/><img src="img/outback.jpg" /></li> <li><img src="img/forester2.jpg" class="imgtophidden"/><img src="img/forester.jpg" /></li> <li><img src="img/tribeca2.jpg" class="imgtophidden"/><img src="img/tribeca.jpg" /></li> </ul> The classes are like so: Code: .imgtophidden {
opacity: 0;
}
.imgtop {
opacity: 100;
}
I am new to jQuery coding (but loving learning) and I want to figure out: how do I make this in jQuery? Here's what I have so far: Code: $(function() {
$("ul.carz li").hover(function() {
$(this).find('img.imgtophidden').addClass('imgtop')
} , function() {
$(this).find('img.imgtop').addClass('imgtophidden')
});
});
http://www.javascriptkit.com/javatut...rnalphp2.shtml Anyone have a decent way of adding a fade affect to this script? Hi, I'm have set up a gallery site, pretty standard stuff with thumbnails to the right and big image to the left. I would like to add a fade in on the big image when the thumbnail is clicked and don't really know how to implement it. The big images are contained in a div called <#left> while the thumbs are within a div called <div class="gallery"> I have searched Google and these forums for a solution but haven't had any luck...can anyone help me out with this? Thanks J Greetings. I am using an image galery script written by another person - frogjs (http://www.puidokas.com/portfolio/frogjs/) This script is showing current pic in the middle of the screen and next/previous little tumbnails on right/left sides of the current. When you click the next pic, current pic is zoomed out to the left and next pic is zoomed in to the middle, then replaced by a full-size pic. Then a new tumbnail appears on the place of the next pic you clicked. Zooming and stuff is done with another thirdparty script "effects" (script.aculo.us effects.js v1.7.0) My problem is, the actual next tumbnail is not being shown until the big image is preloaded for this thumbnail. This is done to make it look smooth. So, when i click "next" picture, the next picture is shown, but switching to the following one is delayed until that following one is actually loaded. It is done by making an imgpreloader=Image() object and setting imgpreloader.onload to a function, then setting imgpreloader.src to the big image path. The big image then is supposed to be automatically loaded by browser. When its done, an onload event should fire and that should execute the function that shows the thumbnail for the big picure. Problem is, sometimes the onload event won't happen! And since it wont happen, my gallery will "stall" - it will never show next thumbnail and never allow to continue viewing. And if i show next thumbnail immediately, the next picture would be shown partially and that does not look good. Moreover, i've seen numerous image galeries on numerous sites and all of them seem to work with onload because i only see the image when its loaded, until that i see some "wait" or "grey screen" thing. Never had a problem with those stalling. Problem happens mostly with Opera and Chrome and happens seldom with IE. So, question is, do you probably know what can prevent browsers from firing and OnLoad event or from loading a picture when its suppied as an src for an Image() object? Do you know a workaround that can "poke" the browser to remind it to get the damn picture again and not to stall. Hi CF, I'm a graphic/designer and occasional Actionscript developer making what's turning out to be a rather clumsy transition into Javascript. Be gentle. I'm trying to create a script that will load an external image and test whether it's in my document's "tall" or "wide" formats before placing it in the page. This is easy in IE just using imageObject.width, but Firefox seems to always return a value of 0, no matter what I do (this includes using imageObject.naturalWidth). Refreshing the page suddenly causes the wide mode to activate, but any time before the image is actually placed in the document, FF just won't read the width. I've tried maybe a dozen different scripts, but here's my most recent: Code: function testImage(){
if (defaultImage.naturalWidth > 320){
wideMode = true;
}
placeImage();
}
function loadFirstImage(){
defaultImage.src = "images/myGIF.gif";
defaultImage.onLoad = testImage();
}
Any ideas on how to accurately get an image object's width after loading, but before placing it on the page? Any help is much appreciated. Thanks, ~gyz Hey guys, I'm trying to accomplish something similar to what the develop on this site did: http://backlinkwatch.com/ When you click on the text area, a clickable image, with a 50% black opacity background overlay, and an exit either through a link or clicking outside of the box, shows up. I want to accomplish the same thing, but have the image popup show up on the page load instead of requiring a click of the text area. In addition, I would like this popup only once to each IP address; ie, if you visit a page on my site, this will show up, but if you close it and refresh the page or visit another page on the site a cookie will be stored that knows its already been opened once and it won't try to do it again. Thanks to anyone who can help me with this! Hi I have this code: <script type="text/javascript"> function Ajax() { var $http, $self = arguments.callee; if (window.XMLHttpRequest) { $http = new XMLHttpRequest(); } else if (window.ActiveXObject) { try { $http = new ActiveXObject('Msxml2.XMLHTTP'); } catch(e) { $http = new ActiveXObject('Microsoft.XMLHTTP'); } } if ($http) { $http.onreadystatechange = function() { if (/4|^complete$/.test($http.readyState)) { document.getElementById('ReloadThis').innerHTML = $http.responseText; setTimeout(function(){$self();}, 20000); } }; $http.open('GET', '../inc/record_count.php' + '?' + new Date().getTime(), true); $http.send(null); } } </script> <script type="text/javascript"> setTimeout(function() {Ajax();}, 1000); </script> Can you help me make this make a fade in effect?? is it possible if you have a div with child divs inside , so i fade out the parent div but the opacity of the child divs stays at 100% ? thank you |
