How can I get HTML's varibles in embeded ruby?

Ruby
1

E.g.,I have following variables:
myInput, DataFile,TagFile in the following segment HTML codes.

    Select Asn1 File: 
    Select Asn1-bas File:

If in PHP, I can easily get them by $p_DataFile, $p_TagFile etc, How can
I get the variables in embeded ruby?

Thanks

just a note, but i don’t think you want the ‘form’ action to go to the
file itself (the rhtml) … it should go to the corresponding action that
calls that template.

i believe what you are seeking for is params[:DataFile],
params[:TagFile], etc.
(this may be good for the ruby on rails forum, rather than this plain
ruby forum) http://www.ruby-forum.com/forum/3

anyway hth.

OP didn’t say Rails. Could very well be serving some kind of eruby.

You probably want to use the CGI class:
http://ruby-doc.org/core/classes/CGI.html

That page has plenty of tutorials on it, but the basics are:

require ‘cgi’
cgi = CGI.new
data_file = cgi[‘DataFile’]

That’ll give you the value of the DataFile text field.

Isn’t hpricot (http://redhanded.hobix.com/inspect/hpricot01.html) an
html parser package?
