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..

Calling Multiple Functions With A Single Body Onload Call?

Jul 19, 2011

I have a web page that has a short flash show on it, then it redirects to the main site index page, using a setTimout in body onload. That was all working fine. Now I need to add an OS detection function to redirect iphone and ipad users immediately (bypassing the flash pape). So, I have 2 functions that need to be in the body onload. I figured the logical thing to do would be to write another function that calls the first 2, then put that one in the onload. But now nothing is working. I have played with in for an hour with no luck.

Just as a note: Original, before I had to add the OS detection, there was just the delayer function, and it was called thusly:

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?

JQuery :: Calling Function Through Onload?

Aug 31, 2010

It's called "Confirm override". This function is called through a click on the button or on the link. Now I want to call this function onload I dont' have really a clue, how to manipulate the current script to make the correct changes.

jQuery(function ($) {
$('#confirm-dialog input.confirm, #confirm-dialog a.confirm').click(function (e) {
e.preventDefault();
// example of calling the confirm function

[Code].....

Calling A Window Function From Within The Html Document Body

Jul 18, 2011

In this example, the same javascript window function is called by two separate form buttons(onClicks) to open('window.open' ) or bring forward( 'object.focus') a window.

One button calls the window function directly from the form and one button calls the window function indirectly from within the body of the html document by first activating a 'document.submit' method .

In particular, using a PC with either Explorer or Firefox, both indirect and direct routes opened a window, but only the direct route could bring the window forward(via 'object.focus') if it was already open. Using a Mac with Firefox, the direct route worked well either to open or to bring forward an existing window, but the indirect route did nothing. On the other hand, when using a Mac with the Safari browser, both routes worked well to open a window and keep it on top.

What do I change or add to get full functionality for the indirect route with the Firefox and Explorer browsers as I get with Safari?

For script, view source at [url]

Calling A Function From Multiple Pages - OnLoad

Nov 19, 2007

JavaScript is not my strong point though and I have found that the previous web editor has a lot of repeat functions on the pages.

My idea is to create an external .js file and just call the function...it is for a rotating banner ad. The problem is the the function is called in the <Body> tag..this means that I have to change 100's of pages by adding the call function to the tag on every page.

Is there a way I can call the function as well as adding the function to the onLoad event.

I have tried adding "window.onload = rotateBanner;" to the beginning of my javaScript but it does not seem to work...what am I doing wrong

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:

Unable To Access Javascript Function On <body> From <head>

Jul 23, 2005

in the body tag, I have this code (just to test):

<script LANGUAGE="javascript">
<!--
function hiThere() {
alert("hi");
return true;
}
//-->
</script>

in the head section, I have this code:

<script LANGUAGE="javascript">
<!--
document.body.onload=hiThere();
//-->
</script>

By the way, I know someone will comment, by "does not work, I mean on
the load of the page, the alert is not displayed, nor are any errors.
Thanks for any help you can offer.

Calling A Javascript Function From A Message Box

Jul 20, 2005

I have simple function that I call from an alert box

alert(testScore);

It works fine. Unfortunately, I do not like the sound and Exclamation
point icon that appears. I'd like a nice message box like VBA message
box #64 to appear. I know hardly anything at all about VB or VBA.
But, I do know you can call a VB function from Javascript. How? Is it
possible to get my testScores to appear from the VB function? Is it
hard? Where do I start looking?

Calling Server-side Function From Client Javascript

Nov 29, 2005

I am developing an ASP.NET (C#) application and need some help. I wish
to call a server-side function (in the code-behind "file.aspx.cs") upon
a user clicking on the "X" to close the browser window. Is there a way
to postback and call a server-side function when this happens? I am
aware of the browser's native "onunload" event, but am not certain that
what I'm looking for is actually possible.

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.

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?
