Ahoj,
chtel jsem pozadat o radu, kde delam chybu. Potrebuji ziskat hodnotu vybrane polozky "option" ve formulari:

<FORM NAME="muj_form" METHOD=POST>
          Vyberte mesic:
          <select name="form_vyber_mesic" id="menu"> 
          <option value="a">1
          <option value="b">2
          <option value="c">3
          <option value="4">4
          <option value="5">5
          <option value="6">6
          <option value="7">7
          <option value="8">8
          <option value="9">9
          <option value="10">10
          <option value="11">11
          <option value="12">12
</FORM>                  

theOptionValue = document.getElementById('menu')[document.getElementById('menu').selectedIndex].innerHTML;
//nebo
theOptionValue = document.muj_form.form_vyber_mesic.options[0].value;
