Window.Onload Function - Finding Elements By ID
May 11, 2009
I'm trying to use unobtrusive javascript for a page I am building. I want to insert a "bookmark me" item into the page. This is the script I am using:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html xmlns="[URL]" xml:lang="en" lang="en">
<head><title>Page</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<link rel="stylesheet" type="text/css" href="/css/base.css" />
<script type="text/javascript">
<!--
function add_favorite() {
document.getElementById('bookmark').innerHTML="<a href="#" rel="sidebar" onclick="if(navigator.appName=='Microsoft Internet Explorer'){ window.external.AddFavorite(location.href, document.title); return false; }else{ this.title = document.title; }" onMouseover="window.status='Bookmark Us';return true" onMouseout="window.status=";return true" title="Bookmark This Page"><img src="/images/bookmark65-3.png" alt="Bookmark This Page" /></a>";
} window.onload=add_favorite();
-->
</script></head><body>
<div id="wrapper">
<div id="header">
<h1>Heading goes here...</h1>
<div id="bookmark">
</div></div>
<div id="main">
<h2>Content goes here...</h2>
</div><div id="footer">
Footer goes here...
</div></div></body></html>
It's pretty simple stuff that just populates an empty div with an image link to bookmark the page when users have javascript enabled. Now when I call the function using <body onload="add_favorite();"> and cancel out the window.onload=add_favorite(); from the script it works just fine (it throws a line-1 syntax error up in IE that I can't figure out, but functionally everything still works in IE7 and FF2). When I try to do it the "unobtrusive" way I get nothing at all in either browser.
A little debugging revealed that the function is indeed being called and is running successfully, however the function is somehow unable to locate the element with ID of "bookmark" when it is fired with window.onload and as a result I get no bookmarking link. It's almost like window.onload is triggering itself too soon, before the div of "bookmark" is in the page, but how can that be?

How to add an onload function to an opened window? (target is "self", not window.open, just a regular link)Is it possible with onbeforeunload or something? Or add onclick to the "normal link"?I mean like this:
<a href="page2.htm" onclick="theWindowIHaveOpened.onload = function(){alert('loaded')}">...

I have a popup window that resizes when open:
<script>
function imgdis () {
window.resizeTo(400,500);
}
</script>
<body
However i still need to make this window to be displayed without Statusbar, Scrollbar, etc. I wanted to be stripped so it only displayes the content. Can i do this from the function that i already set?

When using this script on a external js, it will not run. Trying to learn js and I do not understand why it does not work, when it should. The window.onload should call the function.

How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

Theres this situation where i have to place a js file (say myscript.js) on a client's website to do something on their page (like create a div element with some content in it). Now, myscript.js works when window or DOM has loaded. The problem is that the client will/may also have onload functions which will be overridden by myscript.js if i place it at the end of the page or vice versa if at the top of the page.
Theres one (albeit obstrusive) way in which it can be done. Create multiple onload function (Simon Willison's script) within myscript.js and call that function from the client's webpage.But i dont want to add any inline javascript code on the webpage. Just the external js (myscript.js) file should do. Is it workable to load my script externally and not add any inline call to myscript.js as well as leave the client's javascript onload scripts unaffected?

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:

Is there a possibility to find out the coordinates, relative to the whole
screen, or at least relative to the browsewindow, where an element ( e.g. link or
picture ) begins or ends?

I have a number of elements on a page, which I want to remove. The number changes depending on the number of the results,ie. div Id like result1, result2, result3 etc.Is there a way for me to find out the number of items called resultX or is there a way for me to search through all ID's like result ?

What would be the easier way to do this? For each of the list elements I want to check how many image elements are inside each, and do something with the one that has only one image.
<ul>
<li>
<img src="" />

I am trying to pop up a window and then do stuff(set flags) when the content of the new window is done loading. For this I am trying to detect the window.onload of the pop-up child window but so far I am unsuccessful. I believe my problem is that the URL of child window is on different domain, than the one of the opener(parent) so that the window.onload is not being called. Though this may change, at the moment I do not have access to the code for the page I'm opening up in the pop-up. Im pretty new to web development.

Heres my js code
Code:
//globals
var popupHandle = null;
var openingWindow = false;
function popWindow(URL){
[Code]....
Note: The whole reason why I am doing this is because if its the first time I am clicking on the button that will open this pop up window and I click it repeatedly very quickly, a new pop up is opened for each time I clicked eventhough the window.open is supposed to reuse the window if it has the same windowId. The first call to window.open takes long enough to not have a window handle and allow other clicks to get through.

I would like to find out what script file a function belongs to. Better yet, I would like to know all of the functions that a javascript file declares.
I know that all javascript functions (and global variables) that are declared in a javascript file are added to the DOM. (This is easy to varify by adding a function to a js file and then adding that file to the page and then doing a for (all in window) document.write(all + '<br/>'); (or just looking in firebug) and seeing that your function is there.) What I want to know is what file that function belongs to.

I have a menu system that toggles the visibility of different divs. Here is an example of how my javascript is now:
$("#one").click(function() { $("#m").hide("fast"); $("#n").hide("fast"); $("#o").hide("fast"); $("p").hide("fast"); $("qx").hide("fast"); $("rx").hide("fast"); $("sx").hide("fast"); $("#one").toggle("fast"); return false; });
Is there any way that I can make it so it hides all divs and then toggles the one I want WITHOUT having to write it out like this. is there a 'hide all' option?

Here's the code:
for (var i = 1; i < 5; i++)
var pl = eval("player" + i)
var namepl = eval("document.charInput.name" + i + ".value");
[code]....
In the case of the 2nd-4th player, it changes to name2.value, etc.Based on these three inputs, I need to iterate through all four players and make the player object for each of them, as I've done above.

I can't seem to figure out what I'm doing wrong with this no matter how many things I try. I've looked through Google for a related issue but found nothing specificThe script runs through a external .js file calling a list of music albums, then listing the song of the album chosen via ajax. The user can then edit of delete the songs. Everything works fine until I submit the edited information through a form. When I click the submit button I get a web developer error "updateSong is not a function"Here's the form which is loaded into the already existing page via ajax:
<?php
include("database.php");
$song = $_GET['song'];

win = window.open("http://www.cnn.com", "win", ""); // open window
with CNN
win.onload = onloadfunction;// set onload funciton
but never see google displayed!

Supposedly there are two functions that should run when my page's window loads. One for my clock and one for my new ticker. I can locate the clock function on window.onload, but not the one for the marquee that would stop it from working. Code:

The code below works perfectly in Chrome and FF, but (as usual) it does not work in IE. I think the function "show_guest_notification()" isn't even loading, so does the error lie in the window.onload?
Code:
function show_guest_notification()
{
setTimeout("show_hide_guest_notification()",3000);
}
var i=0;
var c=0;
