Use Function To Redirect Without Using <body Onload>?

May 3, 2010

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?

Call Function OnLoad Of The Body?

Apr 10, 2010

I have a function that needs to get the innerHTML between the body tags once the page loads. However, when I put the JS in the header and call the function using window.onload, it gives me an error. If I put the javascript in the body, it only gets the code above the <script> tag. And I am going to call a server side user control that will put the javascript on the page, so I don't even know where in the page it will go.

It only works when I use the onload attribute in the body tag. i.e <body onload="javascript:fcn_name">

I am using document.body.innerHTML to get the html within the body tags. I tried using document.body.onload and other ways of doing it. Since I am trying to integrate this function within an already existing site, I cannot go through the hundreds of pages and modify the body tags.

Is there an alternative to using the onload attribute of the body tag?

Adding To A BODY-onload Function From Within The Page

Sep 11, 2005

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:

Which Loads Faster, Body Onload Or Window.onload

Dec 3, 2005

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

Window.onload And Body.onload Differences

Jul 23, 2005

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:

Calling Javascript Function Once - From The <body Onload="myfunction"> Tag

Nov 23, 2005

I have been trying to load a javascript function from the body onload
html tag, but I only want the function to load the first time the page
is loaded: I have investigated but haven't found anything that works..
I thought about cookies, but what if the user's disable them?


My code:

//I want to call the Toggle function below only on the 1st time the
page is loaded:

<script language="javascript">

function Toggle(item) {

obj=document.getElementById(item);
visible=(obj.style.display!="none")
key=document.getElementById("x" + item);
if (visible) {
obj.style.display="none";


} else {
obj.style.display="block";


}

}


function Expand() {
divs=document.getElementsByTagName("DIV");
for (i=0;i<divs.length;i++) {
divs[i].style.display="block";
key=document.getElementById("x" + divs[i].id);
key.innerHTML="<img src='textfolder.gif' width=' height=&#3925;'
hspace=&#390;' vspace=&#390;' border=&#390;'>";
}
}

function Collapse() {
divs=document.getElementsByTagName("DIV");
for (i=0;i<divs.length;i++) {
divs[i].style.display="none";
key=document.getElementById("x" + divs[i].id);
key.innerHTML="<img src='Button1_01_over.gif' width=C'
height=&#3937;' hspace=&#390;' vspace=&#390;' border=&#390;'>";
}
}

</script>

// C# code I inserted above the body tag on my aspx page:

function handler()
{
if(<%=!Page.IsPostBack%> )
{
Toggle('support');
}

}

//The body tag with handler being called:

<body onload="handler()">

FYI: The Toggle('suport); function is not being executed. If i put the
function in the <body onload tag.. it does run..

Onload Without <body> Tag?

Jul 23, 2005

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.
sql update on the backend..

Onload Outside Of BODY Tag?

Dec 30, 2003

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.

Body Onload

May 28, 2004

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?

Body OnLoad()

Jul 3, 2004

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?

Onload Even Outside Of The Body Tag?

Dec 18, 2002

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 There Any Call Before 'body Onload'?

Jul 23, 2005

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.

Body Onload Not Fast Enough?

Feb 13, 2009

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" />
<title>Test Page</title>

Alternatives To Body Onload Not Working

Jul 26, 2006

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...
