Onchange script

Hi all.

I have a question about using the ONCHANGE attribute for an INPUT field of a web form.

HTML Code:

<INPUT TYPE="file" NAME="in_file" ONCHANGE=doscript()>

If I understand this correctly, this should call "doscript()" if the value is changed and then looses focus. What type of script does this have to be? Is there any possible way that it can call an external compiled C program?

What I want to do is form a value hint for another field based upon what is entered in this field, where string in the below example would be the created value.

HTML Code:

<INPUT TYPE="text" NAME="in_filename" VALUE=string>

Does anyone have any suggestions on how to do this?

Thanks,
d

From my limited knowledge of this area, in the form you have it, it's generally javascript. You may be able to call a CGI using
HTML Code:

<INPUT TYPE="file" NAME="in_file" ONCHANGE='doscript.cgi'>
but I'm not certain. Bus JS may be the way to go to accomplish what you want to do.
