Firefox No Go - Simple Rollover Opacity Script
Nov 18, 2005
This question has probably been asked many times, but I'm trying to grasp the fundamental differences in how Firefox and IE, for example, interpret scipted code. This should be easy, I saw this fading links effect and wrote a basic script to gradually change css opacity filter values on an object.
Invoking this script with an onmouseover() event in an image or link tag works as expected in IE, but not in Firefox. My guess is there is some minor error that FF is being extra-picky about. Code:

I got a simple rollover with a little twist to it… and I have a little glitch.
The two only images that I am trying to get to swap are:
Button_on.jpg
Button_off.gif
That’s it. And it’s the same images for all 5 links
This means that …
all 5 links should start with button_off.gif. And any of the 5 links should swap to button_on.jpg when I get my mouse over it--while all others remain with button_off.gif.
The rollover works, but the only image that swap is on link #5. That is whether I bring my mouse to link #1 or link#2 or any other link. The only image that keeps swapping is link #5.
Check it out and try moving your pointer over the links and you’ll understand
MY TEMPLATE
Afterward, I’ll add text links above these rollovers using CSS. PS: is there a way to create a similar effect using CSS?

This code works:
Code:
<html>
<script language="Javascript">
if (document.images) { [url].....
What happens: You see both image1 and image3, but when you mouse over either of them, nothing happens...So I'm trying to have "multiple images" rollover...
Edit: So by adding in the red, that's when all rollovers cease to function.

I've tried to make a simple hover effect about small images but it won't work. I also tried to make the following script: 2 seconds after page loading image1 changes 2 seconds after that image1 returns to back state and image2 changes and etc.
<html>
<head>
<style type="text/css">
#as:hover{
background-image: url(images/numr.png);
} #ad:hover {
background-image: url(images/numr.png);
}#af:hover{
background-image: url(images/numr.png);
}
</style>
</head>
<body>
<input type="image" src="images/num1.png" id="as">
<input type="image" src="images/num2.png" id="ad">
<input type="image" src="images/num3.png" id="af">
</body>
</html>

I am having a bit of trouble attempting to get this button roll over stuff working. I have looked up some really simple code to create a image rollover action for my navigation buttons. But nothing happens when I hover on any of the buttons though. When I use firebug to figure out what is wrong, it says that $(this) is the document and not the image button. The example/preview is here: [URL].
This is the jQuery code here for quick reference:
<script type="text/javascript">
$(document).ready(function(){
$('#navigation img').hover(
function() {
$(this).src = $(this).src.replace("Red","Yellow");
}, function() {
$(this).src = $(this).src.replace("Yellow","Red");
}); });
</script>

I have navigation buttons that I'll call primary buttons. I also have secondary navigation buttons that I'll call secondary buttons. If you rollover a primary navigation button, it should make secondary navigation buttons 1,4,and 5 go to rollover state A. However, if you rollover secondary navigation button 1,4 or 5 they should go to rollover state B.So the simplest way I can explain it is that the secondary navigation buttons need two rollover states possible.

Before, I had an iframe, and when I moused over a link outside the iframe, it would load a page into the iframe. Background image was part of the page loaded, as well as the text and what not. The problem was, the image took too long to load. I've been learning how to do javascript and I came across some code for preloading an image before the mouseover so there was zero wait time. For the past few days I've been trying to figure out how to have the preload image appear BENEATH the iframe (now with no background image or color) with the allowtransparency attribute set to true.
I've figured out the code to do both individually, i.e. I have the code so that when the link is moused over, the new image will appear; AND I have the code so that when the link is moused over, the page with load into the iframe. Both work, both do what is expected, but they don't do it together.Below is the script. Here's where it's confusing. If I have the "setupImgRollover..." first inside the if statement: the page loads into the iframe, but there is no image. If I have the "setupImgRollover..." after the "document.link..." commands in the if statement: the image appears but the page does not load into the iframe.
HTML Code:
window.onload = rolloverInit;
function rolloverInit() {
for (var i=0; i<document.links.length; i++) {
var linkObj = document.links[i];
[code]....

I've been trying to get opacity reporting working in IE 5.5 but the
Microsoft documentation does seem to work as I interpret it even though
this documentation page seems have been written for IE 5.5
<URL: http://msdn.microsoft.com/workshop/author/filter/filters.asp>
In the html page listed below I see an error "Library not registered"
in IE 5.5. In IE 6 I see an alert that says "50" as expected.
Some of microsoft's demos on the above page also show the "Library not
registered" error in IE 5.5 but work in IE 6.
Has anyone else experienced these problems with filters? Any idea why
IE 5.5 doesn't work as advertised? Code:

In IE I have a routine that dynamically assigns objects' opacity. This works
fine for some elements but not for others.
It works for buttons and inputs but not for img, span and select.
This is the line that sets opacity from a loop through all elements:
document.forms[0].elements[i].style.filter =
"progid:DXImageTransform.Microsoft.Alpha(opacity=" + FadeOpacity + ")";

I would like to set opacity of some element to 0 through JavaScript, using GetElementById function. This is my short code inside body of HTML:
<script>
document.getElementById("element").style.opacity="0";
</script>
<div id="element">
noopacity
</div>
It doesn't seem to work, what am I doing wrong?

I want to amke something fade out, if and only if it is already set at 100% opacity.
I need to make a function that will allow me to do this.
Here is my current code:
//Time=millisecond Start and End = Amount of Opac to start with. Id = which div to affect
function opacity(id, Start, End, time) {
//frame speed here
var speed = Math.round(time / 100);
var timer = 0;
//
if(Start > End) {
for(i = Start; i >= End; i--) {
setTimeout("Opac(" + i + ",'" + id + "')",(timer * speed));
timer++;
}
} else if(Start < End) {
for(i = Start; i <= End; i++)
{
setTimeout("Opac(" + i + ",'" + id + "')",(timer * speed));
timer++;
}
}
}
function Opac(opacity, id) {
var obj = document.getElementById(id).style;
obj.opacity = (opacity / 100);
obj.MozOpacity = (opacity / 100);
obj.KhtmlOpacity = (opacity / 100);
obj.filter = "alpha(opacity=" + opacity + ")";
}
How would I write a function that would allow me to fade out if opacity was already 100, otherwise it does nothing?

I've got two problems with these functions:[code]The first is that they fade in and out as expected, unless I mouse over any of the text in the div. Then the fadein and fadeout functions seem to compete with each other.The second is that showcount keeps getting set to undefined, so it never gets to 4, where upon fadeout should return without fading the div into the background.I should say that I believe the first problem has to do with mouseover seeing the html as a separate entity from the div, but that seems odd because it's a child of the div!

In Mozilla FireFox I can set the opacity of text/images with
document.getElementById(飓').style.MozOpacity = 0.1;
But with IE, I can only set the opacity of images and not text. Any ideas how to do it?

I've just had a look at your fading opacity script. As I'm new to
programming and I'm amazed by the script could I ask for some hints
how to implement it in a site with a mouseover, mouseout events?

I originally tried this but found it to be quite problematic: [URL]I don't think it's jQuery 1.4 compatible either.I then went on to try a JavaScript script that I found elsewhere, but that also brings up new problems!All I need is a simple bug-free jQuery plugin that will fix the opacity bug in IE6.

I have a bunch of thumb nails that will be at full opacity when a user gets to the page. Users will be able to select their favorite. What I want to have happen is when a user selects their first favorite all of the there thumbnails will be lowered in opacity then when they select other favorites the opacity of that thumbnail will be brought to full. Each thumbnail is in a div. I am at a complete lose on how I can achieve this.
