Call Javascript function from ANSI C program

[Paolo]

Hi to everybody,
i have this problem.
I need to refresh an input text field inside a form on a PHP web page
with a value notfied by a software written in ANSI C language.
I don't want that my C software make HTTP POST operation using CURL on
my PHP web page because i don't want refresh all the page but only the
single input field.
How can I do that?
Does exists a C library that provides some features that can help me?

Thank a lot
Paolo

Hello,

There is no standard way of doing this, because Javascript engines are
mostly browser-dependant, and the rendering engine is not accessible
unless hooking the program in memory, and I'd totally advice you not to
go on such a difficult path, because it could lead to problems and
corruption.

I think you should propose your users a simple copy and paste of the
value, or as you suggested, do a post with curl, on a page, and then
retrieving it through AJAX, But you'll be faced to a session
authentication problem, unless that value is general for all your
users.

Cheers

Ok, I understand.

Ok, but with this way I don't solve my problem because I have to use a
web page that must be entirily refreshed by my application.
With Google I found this:

http://developer.mozilla.org/en/docs/JavaScript_C_Engine_Embedder's_Guide

Do you know it? Can it solve my problem? I not have time yet to read
the guide....

Thanks a lot

It's not a C issue, as such. You can google 'remote scripting'
for more information.

This is an example of why you should not attempt answers to
off-topic questions, other than to redirect the OP to a suitable
newsgroup. He has just continued the off-topic post, rather than
going somewhere suitable. We don't need the additional clutter.

IOW:

Off topic. Not portable. Cant discuss it here. Blah, blah, blah.
