Math in VisualNEO web

Hi,

How can we type math in the visualNEO Web?

I have seen a sample of math in the below site.

https://www.mathjax.org/#demo

Hi @asmat,

Just add the libraries to your project and use the appropiated syntax according to the MathJax documentation.
I have attached a sample (Libraries added from CDN in Project > Properties > Advanced > Custom Metadata > Head)

Regards.

By the way, this is an interesting online editor that makes possible to export to MathML format:

Thank you luishp, this is great!

hi luishp,

I want store a math formula in a variable, I tried this:

SetVar [formula] "$${{n!} \over {r!\left( {n - r} \right)!}}$$"

but when i use this variable with setobjectHTML  command it does not render something that i have expect.
SetObjectHTML "tex" "[formula]"

Hi luishp,

how i can use the above example without cdn, i mean use in offline mode?

@asmat see attached sample.
Just download the .js file and add it to Project > Properties > Libraries/Files

@asmat I have had to follow all the dependencies as the main .js file call other .js files in different folders.
I have used the web browser console to follow step by step the clue for every needed file and/or folder.
See attached file.

Hi @luishp,

I have test your sample in firefox and chrome it works good, but when I add  one more formula it does not work.

Hi @asmat. Please refer to Mathjax documentation to learn how to install it.
In my sample I just added some JavaScript libraries I found in their website by looking at a sample source code but probably I missed some files.

If you look at the Console while running your sample app you will see a message like this one:

Error: Can't load "file:///C:/Users/.../math1/input/tex/extensions/action.js

So it seems an extension file whose name is "action.js" is needed.

Regards.
