Reaching and Pulling Environment Variables in TamperMonkey

Currently my Office is running a AHK script to pull environment variables. These Env Variables are then used as a specific outputted data when closing tickets as my Office has a ticket closing environment. This works for the time being however I am looking into automating this process and starting off just trying to auto close the tickets when a specific key is pressed. I have been able to perform this task but I have to basically have static variables in the TamperMonkey script for each user. Everyone using this ticket site has the specific environment variables already due to the AHK script and want to try and implement this into the Tampermonkey script without having to change the site completely.
I have locally hosted the site and used Node to do this and I am successful in doing this but it does not work on the Tampermonkey route. I have been using process.env.ENV_VARIABLE on the node side but I am trying to refrain from completely implementing this on the site itself. I have added some basic variable examples in a Autohotkey Script already being used.
GetGreeting() {
global greeting
return greeting
}
GetSalutation() {
global salutation
return salutation
}
GetUserName() {
Envget, e_Ticketname, Ticketuser
return e_Ticketname
}
When a specific Key is pressed it should write the specific message and include said specific Env Variables. Currently I don't think I have it where Tampermonkey can actually understand the Environment Variables as it keeps giving a undefined error. Any Ideas.

So upon further investigation it does not appear to be a way to interact with the OS inside the browser. I will be looking into another way to do what I am looking for. Thank you!

You are able to access and run local files as JavaScript code in Tampermonkey using \\ #require
So if you're able to have a local file with the content in this format:
variables = {
var1: "hello there"
}
Then in the script, add this line and add the path to the file.
// #require file://Path\to\file
Since all the file has is an assignment to a variable, then you can access that in the script
console.log(variables.var1) // logs "hello there"
For this you need to give the extension access to file URLs:
go to chrome://extensions
Tampermonkey > Details
Allow access to file URLs
You'll still need a way to generate the file in that format in the user machine though, either manually, or some code running locally.
A way to generate the file, could be using Node locally, but if you're running that locally, at that point another way to get local data is to serve it using a simple http server (like Node server), then you could make a request from Tampermonkey using fetch or GM_xmlhttpRequest
As a side note, a hack I use to run code locally triggered with Tampermonkey, is to use the localexplorer extension. The extension allows you to open files and folder from the browser using "localexplorer://" urls, so then with javascript you can do window.open(local_url) and it will run or open that file/folder. The file can also be a .bat file, and you can run anything from it (including Node code).
There are some security considerations for using this though if you're worried other websites might be able to open files in your system. but the extension prompts you every time you try to open something with localexplorer
If you're still interested on this, a way I use for it to work without the prompt with less risk is this:
The prompt also lets you click the checkbox of Always open links of this type in the associated app for each domain. So then what you can do, is have a specific domain you choose for this, to always use that domain to open localexplorer links, and use a format of your choosing, like secretdomain.com/?C:\\path\\to\\file, and grant access to always open the links on that domain. Then use Tampermonkey to run some code on that domain so that when it detects that specific url format, to redirect the page to a localexplorer url, like this
location.href.replace(/htt.*:\/\/secretdomain.com\/\?/,'localexplorer:')

Javascript to read Text File to Array without a Webserver or external libraries local on Windows PC

I have an HTML file with JavaScript that I am running without any Webserver/host so I am just opening the file in a browser local to my windows PC. In that HTML file I would like to be able to read a text file in the same folder as the html file. That file will contain data in rows and columns separated with tabs. i.e
1 a
2 b
3 c
I want to keep this as simple as possible so all I have to do is share the HTML and Text file to others so the can open it up local to their computer without any webserver/host and without having to also copy of external libraries like node.js or jquery.
I have searched and tested everything I can find but either I need to reference an external library or I have to run it in a webserver or I need to click a button to load the file through the browser, none of what I want.
Does native JavaScript support the function to read a text file and save it to an array? If so, any code direction would be great.

https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest
XMLHttpRequest() exists in native JavaScript, I think it will help you.
You also can send a request to the file. Or use library: axios.js because when you use XMLHttpRequest() you lose many time to write code which just get content from file, with axios I got file content with one line: `axios.get('file.txt').then(result => console.log(result.data));
To connect Axios: <script src="https://unpkg.com/axios#0.18.0/dist/axios.min.js"></script>
You can read official documentation about axios.js and XMLHttpRequest() in the net.

How can I get the source code from a page using javascript

I'm trying to get the source code of that page (using js and d3js library)
http://www.brightpointinc.com/interactive/budget/index.html?source=d3js
I want to run it localy, so i've downloaded the source of the css file and "scripts/d3.js" file and places those file in the right place. However it seems that the javascript don't want to load anyway. Is it possible to run the page localy getting the source code ? If that's the case, how should I do ?

In firefox, you can simply right-click the page and do Save As... to download the complete website including all referenced files.
I looked at the website you mention and the reason that this doesn't work for this website is because this website is not completely client-side. The javascript does server-requests, which won't work on a local copy, because of security reasons.
This results in the following error:
NS_ERROR_DOM_BAD_URI: Access to restricted URI denied
d3.js (row 1674): request.send(data == null ? null : data);

QWebView can't display external image content set via javascript $("#<node_name>").html(<html_content>)

I'm migrating project from MFC to Qt now, and it's using embedded web browser, which displays local (resource) html-page. Local page is displayed fine, no problems. But i have a problem to set html content to child tag. QWebView can't display external images set via javascript $("#").html() - only text and local (resource) images are displayed. In MFC version with IE webview the same script works fine.
I've tried to use QWebElement::setInnerXml, but result is the same: only local content is displayed.
After that i've tried to use QWebFrame::setHtml, but after call app crashes somewhere in QWebPuginDatabase::searchPathes, despite that i'm calling QWebFrame::setHtml from main thread.
Did anyone meet the same problem? Has anyone solution to resolve my problem?
Thank you

You may need to change a setting, try:
QWebSettings::globalSettings()->setAttribute(
QWebSettings::LocalContentCanAccessRemoteUrls, true);
The QWebSettings documentation describes the attribute as (emphasis mine):
Specifies whether locally loaded documents are allowed to access remote urls. This is disabled by default. For more information about security origins and local vs. remote content see QWebSecurityOrigin.

Xml to js code problem

So i'm very new to xml to javascript so i thought I would learn from w3schools, but this site
http://www.w3schools.com/xml/xml_to_html.asp shows an example that I can't mimic locally. I copy/pasted the .js and downloaded the xml but I just get a blank screen!
It's working in there try it yourself but not for me? Do I need it on a server or something?

Yes, that code retrieves the XML data from a web server using AJAX. Since you don't have a server running locally, you can change the URL to point directly to the w3school's version:
xmlhttp.open("GET","http://www.w3schools.com/xml/cd_catalog.xml",false);
Alternatively, play around on their online version ;)

well i guess you have to add the example xml (cd_catalog.xml) to your file system. and you definitively have to access the html file on a server (apache i.e.)

First, ensure that both HTML file (with the Javascript block in it) and XML file are placed in the same directory.
Next, you probably need to place those files under your local web-server and open the HTML like this:
http://[local server host]/ajax.html
instead of opening the file directly from e.g. Windows Explorer:
C:\[path to the file]\ajax.html
For the latter case you'll get an "Access is denied" error.

Are you running this under a web server or just creating a couple of text files and loading them in your browser?
The "GET" request this relies upon could possibly be failing.
Use Apache or another similar HTTP server and run the example as if it were hosted on the web.
