     form = document.getElementById('form');
     loading = document.getElementById('loading');
     results = document.getElementById('results');
     
     $('#Check-submit').click( function() {

         {alert('Indtast venlist et domænenavn');return false;}
         
         results.style.display = 'none';
         $('#results').html('');
         loading.style.display = 'inline';
         
         $.post('domain_checker/process.php?domain=' + escape($('#Search').val()),{
         }, function(response){
             
             results.style.display = 'block';
             $('#results').html(unescape(response));    
             loading.style.display = 'none';
