Hi,

no, sorry, that is not how this works.
JavaScript is just the language I used. It has nothing to do with HTTP/HTML in this case.
You can't just plug something like a HTML4/5 JS runtime into an existing browser.

Cheers

It will be very useful for a DOS browser like LINKS and JavaScript runtime like DOjS to work together though, because the main use of JavaScript is for Internet (in combination with HTML) after all. Your work on DOjS itself is impressive, but perhaps you or someone else can port the code from DOjS to LINKS to make DOS Internet work with JavaScript too, so that your work will become useful to a wider range of DOS users.

Links2 on DOS integration/support would be awesome! Have you considered Nano-X/Microwindows support?

Speaking only for myself....

One of the biggest reasons for using a DOS browser
is that it does NOT support JS and therefore is TONS faster
than JS capable browsers for those sites which do not need JS

This board does not need JS therefore.....

For those sites I visit that do need JS... Linux Firefox

Just want to mention that you can almost always find an option to disable JS on a JS capable browser (such as Firefox or Google Chrome) if you want to visit some website(s) without enabling JS. The same can also be applied to a JS-capable browser in DOS - ideally the user should be able to control whether to enable or disable the JS feature with a simple switch, instead of always forcing JS mode or non-JS mode.

Hi,

in another ahandcan be used duktape for add a JS engine to links as in
Edbrowse

------snip from hom page of edbrowse

The home-grown javascr*** engine worked, but keeping up with changes to an evolving language turned out to be a hassle. Version 3.1.1 used the Spider Monkey javascr*** engine from Mozilla.org, which is also open source. This allowed Karl to leverage some 30,000 lines of code - more than everything he had written to date. And somebody else was maintaining it! That's the power of open source. As of version 3.7.0, edbrowse uses the duktape javascr*** engine from duktape.org.

------
Or try to porting edbrowsing in DOS using DJGCC..

OK, it can't be integrated into a browser to parse JS embeded in web pages.

So.... what _can_ it be used for and how ?

It is basically a DOS/Javascript version of Processing:
https://en.wikipedia.org/wiki/Processing_(programming_language)
https://processing.org/

Processing (and p5js) is a system to create electronic art, visualizations, etc.
You write a (short) programm called a "sketch" which creates a visual effect.

Creative coding is a little bit like demo coding, but with less focus on getting the last bit out of the hardware.
See OpenProcessing for some visual examples:
https://www.openprocessing.org/browse/#

Does this help?
