getElementsByTagName returns an array of form objects.  So, if you  
know for a fact that there will only be one form on the page you  
could write it like this.

function resetForm() {
   var theForm = document.getElementsByTagName('form')[0];
   var formName = theForm.name;
   alert(formName);

   document.formName.reset();
}

However, I don't recommend this approach because invariably someone  
else changes the html and the javascript 'breaks'.  If you could give  
us a little more info about what you are trying to accomplish and  
what triggers the need for the reset we could provide better advice.
