title: Mechanize - Submit form without click on submit button
body: <p>Using Mechanize I fill a fom and I want to submit it without clicking on the submit button</p>
  
  <pre><code>&lt;formulaire POST https://WWW/YYY/XXX.php application/x-www-form-urlencoded
    &lt;HiddenControl(type=traitement) (readonly)&gt;
    &lt;HiddenControl(uid=zzzzz) (readonly)&gt;
    &lt;HiddenControl(no_tt=1) (readonly)&gt;
    &lt;SelectControl(ch_ee=[1;2])&gt;
    &lt;SubmitControl(bouton_m=ttttt) (readonly)&gt;
    &lt;SubmitControl(bouton_m=uuuuu) (readonly)&gt;&gt;
  </code></pre>
  
  <p>In fact the submitting is achieve using <code>onchange</code>function for the <code>ch_ee</code> form and it calls a <code>submit</code> function in JS: <code>this.document.formulaire.submit()</code>. I want to do the same thing, i.e. submitting the form without clicking on any <code>SubmitControl</code> button (this button allows to quit the website) but just by submitting using POST.</p>
