Image Preloader For Html?
Jan 5, 2009
So I wanted to make an image preloader, I found a tutorial and followed as best I could (in all fairness it wasn't the best tutorial), but have got a little stuck.
I think all I need to do is enter the src of the images but I can't see where to put them and if I make an array or make a series of entries.
If anyone could give me a hand I'd really appreciate it as I'm a bit of a noob when it comes to javascript.
This is what I have so far.
Code JavaScript:
function ImagePreloader(images, call-back)
{
// store the call-back
[Code].....

I want to build a loop, which cycles through a set of images and displays each image for a few seconds. In Firefox everything works fine, IE6 also executes the code but gives an script error in the status bar ("not implemented"). The relevant line of code is in red in the code below.
What could cause this ugly error in IE?
Code:
var imgpath = "imgtest/";
var errpic = 1;
var maxpic = 5;
function imgloop(actno) {
if(actno==maxpic) {
actno=1;
} else {
++actno;
}
preload(actno);
}
function imgshow(actno) {
document.mainpic.src = imgpath + actno + ".jpg";
imgloop(actno);
}
function delay(actno) {
setTimeout("imgshow(" + actno + ")", 5000);
}
function preload(actno) {
img = new Image();
img.onload = delay(actno);
img.src = imgpath + actno + ".jpg";
}

Does anyone know why my image preloader isn't working?
<SCRIPT LANGUAGE="JavaScript">
var imagesArray = new Array();
imagesArray[0] = "url/image_1.jpg";
imagesArray[1] = "url/image_2.jpg";
imagesArray[2] = "url/image_1.jpg";
function preloader(){
var preload = new Image();
for (i=0; i < imagesArray.length; i++) {
preload.src = imagesArray[i];
}
}
function swapImage(imgIndex) {
document['imgBig'].src = imagesArray[imgIndex];
}
</script>
on bodyload I call preloader()
a link swaps the image swapImage(0) for example, but the images don't preload, they still end up loading when you click the swap link.

I use this javascript in my site's header.php to preload five menu a:hover images:
<script type="text/javascript">
function preloader()
{
counter
[Code]...
in the body tag. I loads fine in IE7 and IE8, but Firefox seems to ignore it and not preload the images properly. What am I missing here? Did I make a mistake or does Firefox 3.5 just work differently with the loading of these five small images?[URL]...

I have a rather large background image as part of the website layout. It's basically the header. It takes a while to load. I wonder if there is an AJAX or javascript loader that can show a loading gif before the image is loaded and then be removed so it doesn't show when you change pages next time.The CSS for the header is below.what code to use for a preloader? Would be grateful for info about this
CSS
#header{
height: 567px;
width:1000px; [code]....

I'm trying to build an image gallery and I want to shrink all the images a bit to allow for enlarging them on mouseover. I have it working fine locally, but when deployed to my server it doesn't work because the image files are still loading as the javascript executes. What I wind up with is the js using the image's alt tag's text size as the image size, which then gets resized to create a squashed image. What I want to do is preload all the thumbnail images before the the function to resize them gets called so the resize function has the proper dimensions of the images to do the transformation on. I'm using the jQuery.Preload plugin for my preloading functionality.
$(document).ready(function(){
[Code]...
My expectation of this code is that the enable_anim_resize() function will not be called until all the images are loaded, but I don't see any difference in this execution than if I just sequentially put in my resize code after the preload line and didn't use the onFinished callback for the preload method (example below:) $(document).ready(function(){ From my understanding of the documentation and examples of the preload plugin, the enable_anim_resize() function shouldn't be called until all images on the page are loaded, at which point the proper dimensions of these images should be available for correct resizing. Can anyone clue me in on what I'm missing here?

I'm having problems displaying images on a site. Basically I have a to change an image each time a button is pressed on a piece of hardware. This is the code to detect a button press
// Check Button
tstileo = new Image();
tstilec = new Image();
tstileo.src = '/images/1.jpg';
tstilec.src = '/images/2.jpg';
document.getElementById('btn0').innerHTML = (getXMLValue(xmlData, 'btn0') == 'up') ? document.Image=(tstileo): document.Image=(tstilec);
So when the button is pressed/unpressed it should display tstileo and tstilec What format should my HTML code be to display the image ? This is whats there at the moment
<span id="btn0">?</span></p>
When running all I get is text saying [OBJECT HTMLImageElement] This site is being hosted on a microchip, btn0 is a press button switch on the board. The idea is to use this as a remote monitoring system. It runs Javascript XML HTML and CSS. I have spent hours searching for a way to do this ( simple ? ) task but haven't got any further than this. :confused:

I have this simple code here:
var container = document.getElementById(con);
var obj = container.getElementsByTagName('img');
And I want to get the full HTML image tag using the obj value, if you get what I mean. So I want to get this:
<img src="images/image_209948045.jpg" />
by using this: obj[0];

I have a JS which I have already started to try to customise, but I am having some difficulty with it in that when I click on an image, it does not take me to my html page.with care.html. Although all files are in the same folder, I get an error indicating that the fille cannot be found (I have checked the file name spelling). I am not doing any of this online as the Web pages, when working, will be put on CDs.

I currently have a div and am using jquery for ajax stuff. The give is named app_content. I have a navigation menu full of input images. When a user clicks on any of these images it would inject html code in the app_content div which is where the html will be displayed.
Now the problem is that when I inject the html code I also inject javascript/jquery code. I make some more input images to be injected into this app_content div. One image is a button called new post. What I am trying to do is another ajax call to a php script to again inject the html code into app_content div. So like the new post I want to inject a form into app_content. The problem is that when you click on the image it does nothing.
The navigation menu is a different div it's app_nav div. Those images are input images and work find where once clicked it injects html code using jquery ajax to the div app_content. So when the html and also jquery code is injected into this div I have another input image inside this div and want to do the same thing when a user clicks this image which is a input image then it will run a function that uses jquery to use ajax to grab html from a .php file and then inject it in the same div meaning app_content div.
Is this possible?
To Sum up what I am trying to do is have jquery ajax inject html/jquery code in a div and the injected code would have another jquery ajax code where it would do another injection when clicked to the same div it's in.

I've got a simple javascript image gallery I'm using, but I was wondering if it would be possible to use HTML in the description area. Basically I want to be able to create paragraphs, bold text, and links in the description area. Is it possible? Here's what I'm using:
<script type="text/javascript" language="javascript">
function showPic (whichpic) {
if (document.getElementById) {
document.getElementById('placeholder')
.src = whichpic.href;
if (whichpic.title) {
document.getElementById('desc')
.childNodes[0].nodeValue = whichpic.title;
} else {
document.getElementById('desc')
.childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue;
}
return false;
} else {
return true;
}}
</script>
Then the markup:
<img id="placeholder" src="images/twoBottles.jpg" alt="" /> (Where the image appears)
<p id="desc">Choose an image to begin</p> (Where the image descriptions appear)
<a onclick="return showPic(this)" href="images/condiments.jpg" title="The description which in some cases is 2 or 3 paragraphs long and I would like to format somehow">two bottles</a> (clicking this text opens that picture in the image area).

I have a site that is built with a frameset. What I would like to do is whenever I update a particular frame that contains the main content (ie. a news.html page), have it change a graphic in the navigation bar (ie. a separate .html document) to a glowing animated gif for 7 days. Since the news page doesn't load as the first page within the frameset, it would show that there was something new posted there.
I have a few JavaScript books around, and I -think- I know roughly what needs to be done, but I'm having trouble conjugating scripts.
I think it could be done by checking the date.lastModified against the current date, and if the abs difference was less than 7 days it would display news-anim.gif, else it would display news.gif - however I am not sure how to get the left navframe.html to read the date modified of news.html
Can anyone suggest any solutions (or know of any scripts out there?) or is this more of an issue that should be dealt with using cookies/something else?
