Firefox And <body Onload=.. > Firing After Page Is Rendered
Aug 16, 2005
I have some initialization to be done at page load time, which changes
the text of some anchors so that they are consistent with the query
string (these anchors are used as criteria selectors, and should be
initialized to the criteria contained within the url).
IE and Safari fire the onload event before rendering any elements, so
when the event handler synchronizes the anchors, they are rendered with
the right contents immediately. Firefox, though, renders the page
first, and then fires the handler, which results in the anchors getting
their initial values, and then changing to proper selections. I've
tried calling my init() method immediately after the anchors are
defined in my document - no difference, looks like Firefox is rendering
everything as soon as it's encountered in the document.
Is there any way to have my code run before any elements are rendered
in Firefox? Currently I've "solved" this by hiding the containing div
in the document, and showing it after making changes. This results in
the UI visually reloading itself with each new page, which is not very
desirable either.

I am looking for a cross-browser way (Firefox 1+, IE 5.5+) to
have my Javascript function execute from the BODY's "onload" method,
but if there is already an onload method defined, I would like mine to
run immediately after it. So in the code below, what JS would i need
to add to my "myfile.inc" page so that I could guarantee this behavior? Code:

It works on Konquerer though. I remember it works on IE too.
I've tried window.close() too. Doesn't work on Firefox also.
I've also tried to create a function. It doesnt work on Firefox also.
Bottomline is: Firefox doesn't accept window.close() or self.close()?
Are there ways to rectify the issue?

I am having a problem accessing and element by ID in a script that runs via 'window.onload' at the end of all my script definitions. Do the HTML elements exist at that point or should I look somewhere else for a bug?

I wander what gets loaded the fastest (1-2 or 3) in what succession:
<head>
<script type="text/javascript">
function andAction() {
// doing stuff
}
</script>
</head>
<body onload="andAction();">
<script type="text/javascript">andAction()</script></body>
just in the head and nothing more
This I am sure off:
<head>
<script type="text/javascript">
window.onload = function andAction() {
// doing stuff
}
</script>
</head>
<script type="text/javascript">andAction()</script></body>
just in the head and nothing more (should be 1)
Third and last which is faster:
body onload or window.onload

I'm seeing a difference in behaviour between
window.onload = f();
and
<body onload="f();">
Specifically, window.onload appears to fire before all the elements of
the page have been rendered. As the difference is consistent across
IE/Moz/Opera, I'm assuming it's deliberate - can anyone point me
towards where this behaviour of window.onload is defined in the
documentation? TIA. Code:

You do not need to read all of this code but I included it in case any of it was causing the error. The onload event does not fire the go() function (I want to fire this before I actually do what I want to do onload). Why is it not working??? Code:

I need to execute a JavaScript function "onload". The only problem is I
don not have access to the <body> tag as it is a part of the standard
page-header include (a separate file). How could I have certain pages
execute my function() onLoad?
The function basically just sets the original values of fields so that I
can determine if a field has been changed or not, which aleviates unnec.

I'm trying to get a popup working on my site. I use headers and was wondering if there is a way to put the onload outside of the BODY tag? My header has the BODY tag in it. I only want the popup to come up on one page and not all the pages that use my header.

I have created a page that takes a person to another page automatically:
<body
However, the script waits for the entire page to load before actually taking the person to the other page. What I need to do is to have a script that takes the visitor to the target page as soon as the page appears (without waiting for ads to load completely). How can this be done?

Just wondering if anyone knows if it's bad practice to put multiple body tags within one document? I'm using a template system (php) that loads template files into a main template (already containing a body onLoad()), and the content files also have a body onLoad() preloading functions intact. It seems to be working but wanted to know if there is anything wrong with this? What about broswer specific issues?

I'm working in a template environment, and I can't change the <body onLoad> tag (it already had a muti-use function on it.
On the specific page I'm working on, I need some layer visibilities changed (dependant on a cookie) which seemingly can only can be done in the onLoad event.
so I need to add to or capture the onLoad for one page, and no others with a script included in the body data? (and of course it needs to be cross-broswer compliant 5+)

Is it possible to make a javascript call before "<body onload='...'>"?
What I'm doing is a preview of numerous images in an iframe and I want to
resize the iframe to match each picture. Normally I'd use the 'onload' (on
the src-page holding the image in the iframe) attrubute, but it's not called
until the picture has finished loading. I'd like to resize the iframe before
(or at the same time) the image starts loading.

I have a script that I have been using for a while that works with 3 sets of div tags. The first is visible and the second two are hidden. Using a select menu you can swap which div tag is visible by selecting that option.
Now this works fine using <body onload="opts();"> to call the function the only problem is that the page I am running this script on has a lot of images and the second two tabs are visible until the page has completely finished loading. This is only for a matter of a second or two but still a problem.
I am not very smart when it comes to JavaScript and I have messed around with adding window.onload = opts(); to the script but kind of unsuccessful. This works in the sense that the second two sets of div tags are invisible from the start of loading the page. There are only two problems with this solution.
1. The script isn't functional (can't swap visibility on div tags) until the entire page has finished loading. -- I can live with this if I have to
2. There is a javascript error message in IE 'null' is null or not an object. This could potentially scare some people away when they see they yellow triangle in the lower left-hand corner of the window.
Here is the code I am using:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

I tried putting a layer with a high z-index and a clear pixel stretched out in it... I've tried the call as onLoad and as mouseover... I can't get it to work. What am I missing? If you'd like to see my mess, it's here:

I have dynamically named form elements set in divs based on a
server-side language. I am displaying these using DHTML in a
display:none, display:block format.
Due to some code (and deadline) issues I do not have the total number
of form elements set by the time the body tag is run. I wanted to have
a script tag later on in the document which reads something like:
<query>
<builds div element1i1, element1i2, etc>
<script language="javascript">
document.getElementById(' query variable '+1).style.display = 'block'
</script>
</query>
However the JavaScript code does not run. Alerts run inside the code
consistently, but the other code does change the display to block.
also tried running this same code as on OnFocus...

how to use an javascript function to redirect without using <body onload>.
Normally I use this: <META HTTP-EQUIV="Refresh" Content="0;URL=ajax.php?page=mypage">
But since I'm using ajax, and only want to redirect tha ajax part, the above can not be used...
When I have a hyperlink to go to a page in ajax it looks like this: <a href="#" onclick="load('ajax.php?page=mypage','contentarea');return false;">
Is there anyway that I can have the ajax part set into the META HTTP-EQUIV="Refresh" or is there an other way to do this?
