callout to perl

Digger

I need a button that will call a Perl script(this script is done).

The perl script receives 2 parameters and then parse a XML file to finally return the content, to populate a textarea.(No problem at this level)

I use TS 6.5 sp2 on win2000.

I've went thru the doc/forum, if I understand it right I need to use a callout?

I went ahead and create a dummy DCT that just go and popup "hello World" using javascript this work OK.
----- The Code see attachment
------- My problem
How to use it to :
0. Have a button
1. call a perl program with parameters.
2. retrieve return result from perl script.
3. Populate the textearea with the return content.

I'm I using the good approach?
Your guidance would be appreciated.

You really do not want a callout and likely will not use a button. OK, it will be a different shaped button.

I have done similar many times, here is how I approach it.

Set up a checkbox (basically a small, square button) and the text field

In FormApi, on the change event (checkbox) do:

clear check (so it acts like a button)
run a callserver to run your perl script as a CGI
have the callserver return the data to a function to set the text field.


You may need to play with call servers a bit first if you have not used them.
