Running Perl Script from within javascript

von · Feb 13, 2005

Is it possible to run a Perl script from within a javascript?

I have an existing javascript that provides some data - and I want to write
that data to a text file on my server via a Perl script (that I also already
have).

Both scripts work great - I just don't know how to make them work together.

Is this even possible?

Thanks in advance for all input.

Sort of....you can open a window or an iframe from javascript, and you can
post a form. So you can send parmeters serverside in a GET or load a form
from the server, populate it then POST it. The latter solution, although
more laborious, saves a lot of messing around with URL encoding.

Thanks for your input Colin.

What I really want to accomplish is to take, say ...

===================
'Function Data1 ()'
{
[script here];

}
===================

and then send the results of 'Data1' to a text file on my server - all
without any windows popping up and without requiring any user input.

How much data? If a small amount then

var i=new Image();
i.src="pathtoyourscript.pl?data=" + yourdata;

will work fine. But the HTTPRequest path is more robust....

This is a bit rough but will allow you to send moderate amounts of
data and get back a status response.

Thanks Tim.

I sent you an email.

What I am actually doing is generating a small amount of data via the
Javascript - for example an IP address (though that is not it) and then I
want to send that piece of information to a log - that can be viewed via a
URL.

The script works great when outputting this info to the screen - but I want
it sent to a file to store.

I don't really want it writing back to the screen so the response is not
necessary. I also want this completely invisible to the user.

Thanks for all your input Tim.
