I have a login.fcc page which I want to modularize into Javascript,CSS & HTML modules so that it can be maintained easily.
As you know in Siteminder FCC pages we have number of Attributes which we can access and write code accordingly.
When I try to pull this $$smauthreason$$ in seperate js file I am not able to access the attribute value.(this value shd be set by siteminder when this fcc page is called).
Any ideas why I am not able to put this javascript code in seperate js file?
SiteMinder web agent will only serve .fcc files. If you have another file (.js) you must host it on another server instance, but you will not be able to access the SM attributes from it.
As stated before, the FCC file is the only file processed by the web agent,so you can't do the variable substitution in other files.
I think probably what i'd suggest is binding all the variables to 'global' javascript variables in your fcc file. This would allow you to import javascript source files into the HTML that would have access to the variables, but as javascript variables and not $$USER$$,etc type variables.
The other thing you might play with (and I have not done this) is to try server side includes if you're using apache. If the server side includes are processed BEFORE the fcc handler, then you might be able to modularize more.

I'm coding a webpage that needs to read some data from different csv on a path depending on the country of the user.
the path is something like this:
./csv/m2-2022-10-25_13_45_55_es.csv
m2-2022-10-25_13_45_56_fr.csv
m2-2022-10-25_13_46_04_it.csv
etc
And those files will be replaced regularly, the only that we'll always have is the country code (es, fr, it, etc).
So, what I need is to list all the files on the path to an array, and loop through the array to find if the last characters of the filename are $countryCode + ".csv", and there run some code.
But I can't find how, all the solutions I find are using Node.js, but are there a solution using only Javascript (or jQuery)?
Regards!
You cannot use pure Javascript to do that, because if you wanted to search files in your computer only using javascript, it would be a huge security breach.
You must use node.js to open files but you can make an API to your nodejs file from your javascript and you can send as a response the content of your file.
Here some links that might help you :

You can check a similar question here:
Get list of filenames in folder with Javascript
You can't access to filesystem from the frontend, this it would be a huge security breach, because anyone could access to your filesystem tree.
You have to do a function in backend to build the array you want and send it to frontend.
If you create a function in backend file that returns the array of files in the folder, you can call it from the frontend via XMLHttpRequest or Fetch to get the array in frontend and be able to use in your js file.
I am trying to make a compiler in which users make code at abc.com/newProject and their output is in an iframe, that iframe need to be served files that are made at the abc.com/newProject. So I will be doing a POST of JSON obj at abc.com/compile-project that will create files and those will be used by the iframe, after being used those should get deleted. Files are basically JS files that iframe will fetch using script in header.
So a pseudo-code will look something like this:-
app.post('/compile-project', function(req, res){
//Directory created using node tmp
//files created in the directory
//These files are accessible using <script src="/js/file1.js"></script>
//when the current connection requests the files they get deleted
});
Any help will be appreciated thanks.....

I would strongly discourage you from doing that if you don't know what you're doing (and considering the fact that you're asking how to save a file then apparently you don't).
The requirements that you described are extremely simple but you need to have much deeper understanding of everything that's going on to avoid serious security problems that you will encounter with no doubt along the way.
What you describes can be done without even using a file system, since all your files are served only once so it doesn't make much sense to store them in actual files. But even if you insist on the file system then all you need is to use fs.mkdtemp to create a temporary directory, use something like the uuid module for unique IDs to use in the filenames, then use fs.writeFile to write a file. This is all you need for the file upload endpoint. Now in the download endpoint all you need is to use fs.readFile to read the file and fs.unlink to remove it. That's it.
Now, it will surely get you into trouble of failures on browser reloads, back button not working, and finally security issues of people being able to serve any random code from your servers leading to vulnerabilities too numerous to even list here.

I need to have the functionality in the server side in order to hide the implementetion to the final user.
I didn't find a topic with this kind of solution.
I have a .js file with functions I use within the html5 file.
The js files are "called" in the html by using the script tag, but through the url the user can track them and see the .js file content. I don't want this to happen.
$getScript() does the job, but again the url can be cathched, thus the file content too. Much the same with $ajax function.
Everything work ok, but I want to hide the js content.
The .js file is something like this:
var x, x,....
function A(){...}
function B(){...}
and so on, I use A(), B() functions in the html.
Which is the best approach to get the content file from the server without doing the url visible?
Server: nodejs. (I send some json files through socket.io correctly, but I don't know how to achieve this other issue.
Thanks in advance, best!
If you are sending sensitive information to the client then you are doing it wrong. No matter if the client has the URL to the script, they will still be able to find it if they are determined as long as it is sent to their computer.
Find a different way to accomplish what you are trying to do without sending sensitive information to the client. It is not safe.
I have a simple HTML file with some JavaScript that I would like to run locally (as opposed to deploying to a server). It is embedded inside a larger project whose file structure I would like to maintain. For example, the structure is something like this:
project level folder > src folder containing folders & files I would like to probe
> separate, non-project util folder > HTML & JS files I would like to run against src
I am aware that certain browsers do not allow this for security reasons (as pointed out here), but since I control all of the files - is there a way for the src folder/files to somehow indicate that they will allow the 'separate, non-project util folder' to access them? Maybe some kind of project-specific settings somewhere? I am aware that this can be done in server settings, but as I mentioned above I'd like to be able to run it locally without the need for a server.
The JavaScript that is attempting to access the src files uses RequireJS, in case that helps.
Here is what I ended up doing:
I wasn't able to provide full access exactly this way, but instead I setup a dummy HTML page in the project level folder that clicks itself to redirect to the HTML file located in the separate, non-project util folder. This allowed me to keep everything but that one, very small file separate but not have issues with file access.
I'm using JavaScript to generate the text for a CSS file at runtime. I know that I can add this CSS to the HTML document by enclosing it in <style> tags, but it's a large file and my code would be less messy if it were to link to it as an external resource. Is it possible to link to a CSS file generated at runtime? There is no server involved and this must be done client-side.
Disclaimer: I will update this answer as the question is refined.
EDIT
It sounds like you are doing everything locally. In this case, it is not possible to write to your file system from scripts (like JavaScript) running in the browser (largely enforced for security reasons). While you can link and load CSS files from your local machine, you cannot write to them.
OLD ANSWER
You have a couple options, but I am most interested in what environment you are working in. The assumptions are in bold.
JSON color file stored on server: You should be generating this stylesheet on the server-side, and serving it up to your client. This involves creating a route (URL) to access the dynamically generated stylesheet, outputting formatted CSS (not too hard), and setting the headers with the correct MIME types. How you do the last part varies based on your server implementation (Node.js vs. PHP vs. etc.)
Can generate stylesheet only on client side (no server): In this case, assuming you do not have access to a server, but you can fetch your JSON color file (from somewhere, I guess), you really have no stylesheet resource to link to. This really limits optimization potential in terms of cacheing, etc.
Your only real option here is to create and populate the stylesheet in the browser. There is a decent article on how to do that here: Add Rules to Stylesheets with JavaScript
Have you tried this-
loadCssFile = function(fileName) {
var cssLink = $("<link rel='stylesheet' type='text/css' href='"+fileName+"'>");
$("head").append(cssLink);
};
// load the css file
loadCssFile("style.css");
