<a onclick="var url=document.location.href; window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(url)+'&d='+$('#description').text(),'ventanacompartir', 'toolbar=0, status=0, width=650, height=450');"
 href="javascript: void(0);" id="fbCompartir" title="" class="mx">
          <img alt="compartirFB" src="//d2p65vgzoeytng.cloudfront.net/nPromociones/producto/masNochesMasDescuento/img/icoPromoCompartirFacebook.gif">
</a>

    You can’t do this. Not in javascript anyway – the facebook crawler doesnt read javascript. You will need to put the description you want directly into the url being shared. You could always change the og:description on the server in your php (or whatever server language you use) based on a parameter you send in. Make sure you enumerate them though so users can’t write their own descriptions!
