Sticky graphic - Javascript

Merlin

Hi there,

I am wondering how it would be possible to place a graphic on the browser which
sticks to the top, no matter how far you scroll down. I recently saw a banner
and do wonder how they did this.
Have a look http://www.spiegel.de
Is this a DHTML, Flash or JS thing? I was not able to find out.

Thank you for any hint.

Browsers besides IE/Win can do that with CSS position: fixed e.g.
<style type="text/css">
#elementId {
position: fixed;
top: 0;
right: 0;
}
</style>
in the head of the document and then
<img id="elementId"
src="banner.gif"
alt="whatever">

And so with IE when the user moves down the page you have to
dynamically change it's location in regard to the top of the window.

code snippet:

if(document.compatMode != 'CSS1Compat')
{
document.body.scrollTop = '0px';
}
else
{
window.document.documentElement.scrollTop = '0px';
}

you just have to call that whenever the page is scrolled or use an
interval to call it every x microseconds.

have a look at http://dean.edwards.name/IE7/, his ie7 fixes any kind of
ie css problems in ie, but takes rather a lot of system ressources
(that's why i do not use it for just correcting one div).
good way there to implement patches for ie too:

maybe not clear from my 1st post: this snippet is only needed for ie,
all other browser will work with position:fixed.

and i forgot one more thing:
if you use position:fixed you need to set position to absolute for ie
before trying to scroll.
this line should be 1st line in above snippet:

YOUR_ELEMENT.style.position = 'absolute';

Hi Micha,

Martin and you are right, the code works excellent on all non IE browsers:
<style type="text/css">
#elementId {
position: fixed;
top: 0;
right: 0;
}
</style>
in the head of the document and then
<img id="elementId"
src="banner.gif"
alt="whatever">

The spiegel site seems to have done it just that way since in IE the site
clearly shows a movement of the graphic on scroll while it does not with firefox.

I must admit that I did not understand your code as I am a bit a newbie when it
comes to JS. Could you create an working example code for me? That would be great.

Thank you in advance,

Merlin

2 files (change path if they're not in the same dir on your site)

i leave out stuff not needed for functionality

page.htm
ie-fix.js

page.htm (relies on a bug, actually: only ie executes js in comments)

<html>
<head>
ALL meta tags



</head>
<body>
<div style="position:fixed" id="FIXIT">some text</div>

... rest of document
ie-fix.js:

function fix()
{
//handle for the div
$fix = document.all.FIXIT;
//i don't remember why i put in this line
if(typeof($fix) == 'object')
{
//making position understandable for ie
$fix.style.position = 'absolute';
//finding out scroll position of document and putting div at
the top of the screen
if(document.compatMode != 'CSS1Compat')
{
$fix.style.top = document.body.scrollTop;
}
else
{
$fix.style.top = window.document.documentElement.scrollTop;
}
}

//setting an intervall to call fix() every 1000 microseconds
$int = window.setInterval("fix()", 1000);

that's it. hope it works, i didn't test. post if it's not ok, i'm

Hi,

thank you for the example. It workes for IE if the tag is absolute:

<img style="position: absolute; top: 0; left: 774;" class="positon"
src="/g/p/tmp/test_right.gif">
but it should be fixed for other than IE.

Any idea on how to include an else into this if lt IE thing?

Thanx,

Merlin

For javasript,ecmascript, or jscript to detect IE,

use something like

var bIsIE = document.all

THAT is detection from script.
---------------

conditional comment methods in IE won't work with xml/xsl at this time.

e.g. web.xml !--> <!-- [ when Opera/Netscape/Forefox use css else xsl ]>

In what sense does assigning a local variable a reference to an object
on IE, Opera, IceBrowsers, Safari, Konqueror, Omniweb, iCab, Netfront,
etc, and an Undefined value on Netscape, Mozilla, Firefox, Escape, etc,
represent using "javasript, ... to detect IE"?
