Fading A Layer. Is This Possible?
Jul 23, 2005
I am trying to make a banner the size of the with of my screeen, in
a layer.
BUt I also want to fade it to a complete transperency to reveal the contents
of what's behind it (my page ofcourse) and possible close or hide the faded
layer.
I've seen stuff like that happen in a flash everonment. I was thinking about
using a transition at first to go from one page to another with an
introductory page.
But I rather have everything on one page and just fade the introdutory layer
into the page. Is that too much work for jscript?

Layer writing in Netscape. This is pretty straightforward >> However I'm trying to write to a <div> layer within a <div> layer.
My div:
Code:
<div id="blah">
<div id="aight">
</div>
</div>
I'm trying to write to "aight"
How should my code look?

I have created a floating layer using Javascript that remains always on top of page on scrolling.Issue is,at some point while scrolling,the layer flickers continuously.
The html page is as follows:
Many common software systems, JavaScript has a history of security problems. Many of these problems could allow a person with malevolent intent to steal sensitive information from a visitor. The number and type of such holes in security vary among browsers and operating system versions. Most JavaScript security holes have been caught and fixed, but new ones are being discovered all the time. For a list of current security holes check out your browser's and operating system's Web pages. As a Web site author, it is your responsibility to keep up-to-date on the current status of known security holes in the applications you create.
Signing Scripts. In Chapter 11, I explained that JavaScript does not provide the ability to directly access files on the client computer. This can be a very large hurdle to overcome if you're trying to upload a file to a server from the client computer. Fortunately, file uploading is one of many functional enhancements that signed scripts provide. Signed scripts are specially packaged scripts that have been verified and signed to be correct and non-threatening. These scripts have additional rights on the client computer that allow a programmer to do many things that he wouldn't otherwise be able to.
With the introduction of Netscape 4.0, a new security model was put in place that would allow digitally signed scripts to bypass some of the restrictions that had previously been placed on them. A signed script can request expanded privileges from the visitor and, with the visitor's permission, gain access to restricted data. A signed script requests these additional permissions through LiveConnect, which allows your JavaScript code to communicate with the Java Capabilities API. The security model allows JavaScript to access certain classes in Java in order to extend its functionality while still maintaining tight security for the client.
A digital signature is a fingerprint of the original programmer, and it allows the security model of the browser to detect where (or from whom) it originated. A script signer can be a person or an organization. By signing a script, you acknowledge yourself as the author and accept responsibility for the program's actions. A signed script contains a cryptographic checksum, which is just a special value that ensures the signed script has not been changed. When a digital signature is detected, you are assured that the code has not been tampered with since the programmer signed it.
Once you finish writing a script, you can use the Netscape Signing Tool to digitally sign it. Signing a script does the following:
Unambiguously assigns ownership of the script to a person or organization.
Allows an HTML page to use multiple signed scripts.
Places the signed script into a Java Archive (JAR) file.
Places the source of the script in the JAR file.
Once a user confirms the origin of the script and is assured that it has not been tampered with since its signing, he or she can then decide whether to grant the privileges requested by the script based on the validated identity of the certificate owner and validated integrity of the script.
JAVASCRIPT FILE IS AS FOLLOWS:
AND CSS FILE IS AS FOLLOWS:
At some point while scrolling,the div 'movable' flickers continuously,while at some other point,it is perfectly stable.

My site works fine in Firefox, but it crashes in IE.
I am using alot of jQuery in order to fade in content. When the user clicks on one of the above links a few times, it will crash in IE.
Here is my site code...
I have absolutely no idea why the site crashes in IE. I don't even know where to begin to debug my problem. I don't have Visual Studio on my computer, but on my friends computer Visual Studio reads a message of An unhandled win32 exception occurred in iexplore.exe[####]

How am I able to have a gallery of images fading in and out as the background of a DIV? It's currently just a static background using CSS.You can view the HTML page in question here: http://aksdesigns.co.uk/temp/template.html
The DIV container is the one with the ID of #MainContent
#MainContent {
width: 980px;
height: 550px;[code].....
It probably couldn't be done using CSS be how could I achieve this with Javascript?

I've prepared the following page: [url]
But I would prefer the background images to fade in and out rather than change abruptly. I've spent hours searching for appropriate code, but have met a dead end so far.
Incidentally, I presume that the delay before the first background image appears is because of all the images pre-loading. Can anyone suggest a way to immediately display the first image?

I used to use this function in text fading routines (tooltips/message tickers) but now I tend to use opacity (which is not compatible with all browsers but I find it more flexible as it allows images, URLs any style sheets). The function returns a color "between" 2 colors.
/***********************************************
*
* Function : getColor
*
* Parameters :start - the start color (in the form "RRGGBB" e.g. "FF00AC")
*end - the end color (in the form "RRGGBB" e.g. "FF00AC")
*percent - the percent (0-100) of the fade between start & end
*
* returns : color in the form "#RRGGBB" e.g. "#FA13CE"
*
* Description : This is a utility function. Given a start and end color and
* a percentage fade it returns a color in between the 2 colors
*
* Author : www.JavaScript-FX.com
*
*************************************************/
function getColor(start, end, percent)
{
var r1=hex2dec(start.slice(0,2));
var g1=hex2dec(start.slice(2,4));
var b1=hex2dec(start.slice(4,6));
var r2=hex2dec(end.slice(0,2));
var g2=hex2dec(end.slice(2,4));
var b2=hex2dec(end.slice(4,6));
var pc = percent/100;
r= Math.floor(r1+(pc*(r2-r1)) + .5);
g= Math.floor(g1+(pc*(g2-g1)) + .5);
b= Math.floor(b1+(pc*(b2-b1)) + .5);
return("#" + dec2hex(r) + dec2hex(g) + dec2hex(b));
}
/*** These are the simplest HEX/DEC conversion routines I could come up with ***/
/*** I have seen a lot of fade routines that seem to make this a ***/
/*** very complex task. I am sure somene else must've had this idea ***/
var hexDigit=new Array("0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F");
function dec2hex(dec){return(hexDigit[dec>>4]+hexDigit[dec&15]);}
function hex2dec(hex){return(parseInt(hex,16))}

It is not problem of the original script as the fade works very well as you can see at: [url]
The code of jquery-1.3.2.js and jquery.galleriffic.js is exactly the same as I'm using the same files...

How can I create a fade with javascript that fade an activex object
(quicktime) to the background and not to the IE windowed control.
I call this function several times, each time decreasing the "opacity".
id is the quicktime activex object.
I have tried to set background:tranparent and
background-color:transparent in my style sheet.
//change the opacity for different browsers
function changeOpac(opacity, id) {
var object = document.getElementById(''+id+'').style;
if (object.opacity) {
object.opacity = (opacity / 100);
} else if (object.MozOpacity) {
object.MozOpacity = (opacity / 100);
} else if (object.MKhtmlOpacity) {
object.KhtmlOpacity = (opacity / 100);
} else if (object.filter) {
object.filter = "alpha(opacity=" + opacity + ")";
}
}

I have a photo blog [url] and want to create an effect that fades-in the displayed picture when the page is loaded.
An important requirement for me would be that the page also has to work without Javascript.
Currently I am using the following small plugin:
It is called directly beneath the <img> element:
This way it works fine with the current versions of Firefox and IE. I did not test other browsers or versions yet. I tried to call it in $(document).ready but then IE might display the picture shortly before it is hidden and faded-in.
Since I am not 100% happy with having the code in the middle of the HTML and with depending on the timing of execution to avoid flickering I wanted to ask for other solution or best practices to achieve what I would like to do.
One solution that came to my mind is to do create the image in JScript and only fade it in after it is loaded. To work without Javascript I could still put the <img> element where it was but within a <noscript> element. But not sure how well the <noscript> is supported by older or exotic browsers.

I have written the below script to swap images in a main viewer for a gallery on a website (I apologise if the script is not very elegant I have only just started learning JS).The idea is there are 2 divs one positioned on top of the other, when the user clicks on one of the thumbnail images the div on the bottom changes to the new image, then the top div fades to transparent to reveal the new image, then once the top div is completely transparent it's image is swapped for the new image and it is made opaque again.Anyway elegant or not the script works fine in Firefox, Safari, Camino and (shockingly) IE, but it doesn't work at all in Chrome.
Code:
var fadeTime = 800;
var newImage;
var images = new Array();[code]....

Alrighty so here's what I have. Live example: [URL] It's a image slideshow that dynamically gets all the images (via php) in the current directory and puts them into the slideshow array. The array then randomly displays the images in the slideshow (via javascript). There are 5 images in the folder rotateimage which also has the php script getimages.php in it. Currently only the first image fades in however I want all the images to fade in as the first one does.

I'm designing a page to fade multiple images (three) in and out over a set period of time (one minute, say). The code I have works as follows:
I define an array and fill it with the div objects I want to fade in and out. I have some simple tags (2 for opaque, 1 for fading in, -1 for fading out, etc.) that I set to show the state of the object.
First I check if the object is opaque, and if so set it to fade along with a time;
Or if it's transparent I give it a 1 in 10 chance of fading in during this iteration. If it's currently fading in or out I check to make sure it's on track and change the opacity of the div accordingly.
Originally, I had the function call back to itself using setTimeout after the loop had gone through all the divs and changed their opacities appropriately. This caused an out of memory error (though, strangely, if I had any alerts in the function it didn't give me the error).
So the version below has the code in a while loop to let it run for 20 seconds - this gives me the "a script...run slowly, do you want to continue the script?" message.
So I have several questions:
1) First and foremost, why is my function causing out of memory/run slowly errors and what is the best way to fix that?
2) Is there a better way to code this effect (final result will be six lights fading in and out for a minute or so).
3)I'm not an experienced programmer, so any bad practices, ways to streamline, no no's, etc. that you see, please point out.
I've only posted the script here - the page simple consists of three divs (id's grad0, grad1, grad2) and a call to the function copied here.
