How to run a JavaScript?

[pptxman]

Hello,

I want to execute a JavaScript that converts numbers to text (e.g. 500 → five hundred). I found great script on the web(https://skynet48.ru/javascript/summa-propisyu-na-javascript/) and now trying to create workflow but got stuck. The idea is to type numbers and get them in text. Please help.

<script type = "text/javascript" language = "JavaScript">

Welcome @pptxman,

 

You can’t just run any code anywhere. The code you posted is made to work inside a web browser. Technically you can run JavaScript outside the browser with default tools in macOS, but not all features are supported and that code is geared specifically towards writing to a web page.

If you can find some in code in Python, Ruby, Bash, PHP, or Pearl, running it in Alfred is easy.

[deanishe]

Yeah, the code that does the conversion could be pulled out and used in Alfred (or more generally, anywhere), but that is a browser script.

 

With JavaScript, it's important to understand the difference between the language and the browser. Scripts aren't run the same way outside a browser, and a lot of common functions and APIs are provided by the browser, not JavaScript itself.

 

The script uses a CSS selector target and document.getElementById() for all its input and output, but document and elements and CSS selectors are a part of the browser environment, not JavaScript itself.

All Alfred scripts must follow the UNIX model, and use ARGV and STDOUT/STDERR for input and output because that's what's available in the environment the scripts are run in.

Thank you for helping
So I managed to find script on Python, watched a video on how to run python script with Alfred but with no luck. No surprise since I have 0 programming skills. Could anybody please help me to create this workflow? Find my attempts here: https://1drv.ms/u/s!AkuQBe-rRIt9ocgDf74x8uamsWcFaQ?e=y4zelt
