Add External Js File On Client Webpage And Leave Window.onload Function Unaffected?
Jan 15, 2009
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 work for a small college and we were recently given permission to use a particular GPA calculator on their website. They sent us a javascript file, that I now have. I am trying to incorporate this into our website, but I don't really know much about javascript and I am having trouble making it work.
You can view the GPA calculator here to help clarify what I mean... If someone could just help point me in the right direction or if anyone know a site with tips that would be helpful to me..

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.

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?

I'm trying to execute a function in an external js file. I have the file linked
Code:
script type="text/javascript" scr="./JScript/JSFile.js" language="javascript"></script>
In my form the action points to the JSfile
Code:
action="JSFile.js"
My submission button has a link to the JS function
Code:
<a hef="javascript: function()"><input type="submit"></a>
When I click the submit button, it shows the JSFile instead of executing the function.

Below is a sample HTML code for including a javascript file.
Code HTML4Strict:
<!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">

When i browse this test html page on Firefox, the alert message is displayed as on the code above. But on IE, the page shows no such alert message.I assume this is a problem with the functions on the external js file not being recognised in IE.

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!

I have a few buttons on a page I'm developing and I want the onclick event to call a javascript function in an external file and execute it. I would like to be able to pass a parameter to that function and then either have the function take the user to a new URL or make changes to the webpage content.
Initially (just to test) I had inline javascript that caused an alert to popup. That worked fine. Next I took the inline code and put it in a function in an external javascript file that was referenced in the HTML:

turning the following inline code:
<a href="http://www.bing.com/" name="bing" onclick="return !window.open(this.href)">Bing</a><br>
<a href="http://www.lycos.com/" name="lycos" onclick="return !window.open(this.href)">Lycos</a><br>
[Code]....
into an external javascript function that will do the same thing (open all links in a new window individually if javascript is enabled, without destroying links in html for if javascript is not enabled).

It launches in IE and give the user instructions, then at the click of a button, launches my setup.exe. I want my webpage to launch setup.exe then go to another webpage on my CD, congratulations.html, which says "installation is complete etc". Here's what I am trying to do through JAvascript. It doesn't work. Should the first instruction be flushed in order for the 2nd one to work?

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:

I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:
1. Malicious user trying to collapse the website sending big files.
2. Users that have not seen the warning “Maximum size: 100 KB� for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.� And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!
I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:
“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
