title: automatic filling and submitting form with Perl :LWP
body: <p>i just got into web programming with perl and I am trying to write a perl script that will go to a web page (<a href="http://211.157.104.77:8080/sipo_EN/search/tabSearch.do?method=init" rel="nofollow noreferrer">http://211.157.104.77:8080/sipo_EN/search/tabSearch.do?method=init</a>),
  fill in the Input text field, and then submit the form. As it is not working, i wonder what url should i give "post" if not the one i already tried. </p>
  
  <pre><code>   $ua = new LWP::UserAgent(keep_alive =&gt; 0);     
     $ua-&gt;proxy('http', $proxy);
     $cookie_jar = new HTTP::Cookies();
     $ua-&gt;cookie_jar($cookie_jar); 
     $ua-&gt;agent('Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1; .NET CLR 2.0.50727)');
     $url  ='http://211.157.104.77:8080/sipo_EN/search/tabSearch.do?method=search'; 
     $response = $ua-&gt;post( $url, { a =&gt; "03085931", b =&gt; "",
                                    c =&gt; "",d =&gt; "",e =&gt; "",
                                    f =&gt; "",g =&gt; "",h =&gt; "",
                                    i =&gt; "",j =&gt; "",k =&gt; "",
                                    l =&gt; "",m =&gt; "",
  
      } );
  
    $cgi = CGI-&gt;new();
    print $cgi-&gt;header(), $response-&gt;content(); 
  </code></pre>
  
  <p>After filling in the form, the Webpage returns a result list of documents, which i'd like to access in the end. I already tried to find out, and also read about  WWW::Mechanize, but since the page i'd like to access owns javascript, i think it wouldn't work. (Also there isn't really a submit button, just click events) </p>
  
  <p>Best regards </p>
