Dynamic JavaScript Source
Apr 29, 2004
Can I control the src attribute of a header <script> tag so that it loads a different script file depending on the value of a variable?
I have a javascript file that currently holds the variables for several countries and weihgts too much for a single file. I estimate that only 2-3kb of the 40+ that it now holds are used at any given point depending on the user's chosen country.
Now, I can split the file into several smaller files to reduce loading time but only if I have a way of dynamically loading the different files.

Does anybody encountered this problem ? My purpose is to change the source of a flash object from param_src = window.location.search.substring(1)
so the essential code is something like this:
command = '<object ... src="' + param_src + '" ... TYPE="application/x-shockwave-flash" ...</object>'
document.write(command);
This works on FIREFOX but IE keeps playing the same file instead of playing a new one !
I have tried to add the no-cache meta-tags in the header but it still doesn't work.

I'm trying to insert a dynamic js file which contains multiple functions in it (for the example : function x, function y) and it seems that my google chrome doesn't really like it so much. Is there anyway you know I can bypass it and make it work and both web browsers.
Code examples:
// this is where the js file supposed to go
<script id="ScriptFile">
</script>
//1.js contains function x and function y
document.getElementById('ScriptFile').src = "/Mysite/js/1.js"
Later on I need to preform some actions with function x & y. Couple more issues I need to explain first there are number of js files (1,2,3 .... n ). Which all contain the same functions but with same data so i cant register them hard-coded. If I type the function x into the "ScriptFile" block, it does work.. its not the function problem. Same goes if i include it as source in the "ScriptFile" block (<script id="ScriptFile" src="/Mysite/js/1.js") this only gives me an error while using chrome, works perfectly fine under explorer the error says it cant find function x.

I have two frames. "Top" contains a local file on my server with the aforementioned javascript. "Bottom" is a remote website on a server I do not control. I want to use javascript in "Top" to determine what the current url is in the "bottom" frame...

I have a small script that creates and removes elements from an html form. This script also renames some elements upon deletion of another element. But this does not seem to be working properly. The problem is that i can't really figure it out so i was wondering if there is a way to see the source code that is created by JavaScript,in order to track down where the problem is.
function removeDiv(divNum){
var container = document.getElementById("container");
var removedID = document.getElementById("div" + divNum);
container.removeChild(removedID);[code]....
// the code below works if i delete the "for" above, and doesn't work if the "for" is there. specifically, if the added elements are 5 or more and i delete the last one, the value of y remains the same. if i delete the first or one in he middle, it works. if i delete the last and reduce the elements to 1,then add another 5 and delete the last one (as it would not work initially) it works!
var y = parseInt(document.getElementById("totalElements").value);
document.getElementById("totalElements").value = y - 1;
}
<input type="hidden" name="totalElements" />
The value of totalElements increases every time an element is added and this works well.

I wrote some JavaScript I misguidedly thought cool, and felt like sharing it with the world. So I put a link to the source file in my blog. If I click on the link in Mozilla, it shows the source as text, as intended. If I click on it in Internet Explorer, I get a choice between saving the file or opening it, where 'opening it' means 'trying to run it and getting an error.' Putting Code:
type="text/plain" in the a tag doesn't help. Does anything?

I got some code that loads divs from other web pages into a particular div in my main page. In other words, I click on a button, and this tells jquery to load afragment of a particular page into my main page. For instance if I have 5 web pages onrock stars, I could have 5 buttons, and each button could load one rockstar's biography into a div on the main page (and replace whatever was there before). This works, and I do see the content that it loaded. But when I do 'view source' in IE, I do not see that content (the bio of the rock star). Another clue that this content is not really there, is when I try and run some code on that content. The content (from those external pages) have divs with specific names, and I try and make them into collapsible panels by running the following short function:
var IdentifyPanels = function() {
$("DIV.ContainerPanel > DIV.collapsePanelHeader > DIV.ArrowExpand").toggle(
function() {

recently i noticed that all of my embedded JavaScript code and external style sheets are being shown IN "view source."
this happens in all browsers ( IE, FF, Chrome, and Safari [windows]) ... oddly enough it only happens when viewing on my vista or win2k3 machines. is this something added to these OS's or the result of an installed program? has anyone seen this before?

I have a website that I frequently visit (FWIW, Firefox 3.x is my browser of choice) with many image sources referring to URLs that end with "-thumbnail.jpg". However, for better image quality, I am trying to use Greasemonkey to replace all instances of "-thumbnail.jpg" in the source of images on this site with "-bigthumbnail.jpg". The closest I could think of was to somehow use getElementsByTagName and innerHTML.replace, but realized that innerHTML does not do HTML, only content.
Below is as far as I tried to get on my own,
var as,ae;
as = document.getElementsByTagName("img");
for (var i = 0; i < as.length; i++) {
ae = as[i];
ae.innerHTML = ae.innerHTML.replace(/-thumbnail/gi, "-bigthumbnail");
}
})();

I'm merely trying to grab a value from a form and insert it into a javascript. Any hints as to what's wrong with the code below?
Request.form("AMOUNT") as used below does not bring my value into the
javascript (This is related to GoToast ROI Conversion tracking).
<script language="javascript">
<!--
if (typeof(ROIID) + '' != 'undefined')
{
TrackEvent('Sale', request.form("AMOUNT"));
}
//-->

We have a dynamically created javascript menu (from ASP), which is
customised per user (Have already taken all the static code out into
separate cached .js file)
The size of the 'dynamic' menu content can be as much as 10kB, and the
menu typically does not change for the duration of the user's session
- i.e. it would be nice to get the browser to 'cache' this. It is an
Intranet application, and is typically aimed at IE6 clients only.
Have considered the following strategies
1) Cookies - although the last thing I want is the whole menu coming
back to the server on every HTTP request - but would be useful IF
there is e.g. a header option the cookie to 'send' the cookie (Server
-> Browser) without the browser ever sending it back to the server
(but the browser still being able to 'read' the cookie?)
2) Creating 'dynamic' javascript files - i.e. send the output per user
to a mangled .js file (e.g. with a session ID in the filename), into a
cached js file. Would however need to cleanup the files quite
regularly, and giving IUSR file creation access doesn't seem a good
idea. Would then get the browser to include the JS by generating ASP
along the lines of.
<script language="JavaScript"
src="TempScripts/Menu<%=UserSession%>.js"></script>
Is there any other way?
Second Question : Is there any way to get IE to stop sending up the
HTTP REFERER header up to the server (e.g. RegKey) - this is pretty
pointless on an Intranet App (I know there is a way to do in
NetScape).

I have this dynamically created table in my one of my php forms
that shows the names of the people the user has entered into a text
field. When they hit add a row displays, showing the name they entered.
Also, an image that allows them to delete shows beside the name upon
creation.
The delete removes the name from the table and pushes the
other names to the top. Simple stuff, however, if I delete the last
name displayed(the bottom of the table), then the next, then the next,
IN ORDER, I have no problems. If I pick a name that is in the middle or
top of the table, everything below does not allow me to delete Code:

I've got a page that creates an iframe and uses javascript to write to it.
Works like a charm in IE but not Firefox.
<script language="JavaScript"><!--
document.write ('<iframe width="100" height="100" name="myframe" src="blank.htm" FRAMEBORDER="1" scrolling="no"></iframe>');
document.frames[0].document.open();
document.frames[0].document.writeln('<html><head></head><body>');
document.frames[0].document.writeln('YO!</body></html>');
document.frames[0].document.close();
//--></script>
What I get in IE is the "YO!" written to the iframe. What I get in Firefox is the 404 not found page of the site where the original "jstest.html" page and script are hosted.

In a JSP page I am trying to disable a Trade Class drop-down list if the user does not select the ADULT option of the Division drop-down list.
Therefore, Trade Class drop-down list availability depends on the option selected in the Division drop-down list. For instance, if the user selects the KIDS division option then the Trade Class drop-down list should be disable.
I am trying to use JavaScript to do this but I can't get it to work. I have the OnClick attribute in the Division drop-down list so that when a user selects any option from the list the index gets past to the JavaScript function. In my drop-down Division ADULT has index 1.
function enableDisableTradeClass( ) {
var index = document.frm_container_shipments.drp_division_fltr.selectedIndex;
//alert('Selected Division= ' + index);
if ( index != 1 ) {
document.frm_steps.drp_trade_class_fltr.value = "";
document.frm_steps.drp_trade_class_fltr.selectedIndex = 0;
}}

I would like to build an HTML page that has four content areas. The first with 3 links that when clicked chage what is shown in the other 3 - and so changing the default content in these sections. The content for these sections will be contained in seperate HTML files sitting on the same server.
I understand this can be done without refreshing the page and believe JavaScript and Ajax is the best method to do this. Any advice?

Question: How hard is the following to do in javascript and does anyone have a good example of this in use (aka how do you do it? )
4 drop down boxes all on one page. I have 4 items in the list of the first drop down box.
Red
Blue
Green
Orange
When I select one, I want the choice to be taken out of the list for the second drop down box. So if I select Blue in Drop Down #1, Drop Down #2 now has the option of
Red
Green
Orange
If I select Red from the list the Drop Down #3 now has
Green
Orange
Then if i select Orange, the last drop down has only one value and that is Green.

I have a form that has been dynamically created from PHP. It is basically a calculator and the number of form elements as well as names of the elements can vary greatly.
I basically want to add a button that will open a new browser window with the form info being passed to it. Basically it will create a quotation for the customer that is suitable for printing.
The only way I know to do the popup window is with javascript (unless php can do it). I know how to access form elements with javascript if the form element exists, but given most of the elements may change, I do not know how to access them.
