Some jQuer Code

 // How to show loading-div after submitting a form with jQuery?
 $('.formtrigger').click(function() {
      $('#loading').show();
      $('#form').submit();
    });
/*When I click the button, the form is submitted, but the loading-div doesn't appear. 
I tried the line "$('#loading').show();" without binding it on the click-event and it worked. I also tried this code:   */ 
    
$('.formtrigger').click(function() {
    alert('blablabla');
    $('#form').submit();
});
