getElementById('form') to get form items

[HeadBut]

is it possible to getElementById('form') then get form inputs? Looking for an example for a dynamic form with a dynamic number of form inputs?

Thanks

<form id="myForm" action=""> 
 <div> 
  <input name="foo"> 
  <input name="bar"> 
  <input name="xyz"> 
 </div> 
</form> 
<script type="text/javascript"> 
function getFormItems() 
{ 
 if(!document.getElementById ) return; 
 var f = document.getElementById( 'myForm' ); 
 // Step through the form elements 
 for( var i = 0; i < f.elements.length; i++ ) 
 { 
   alert( f.elements[i].name ); 
 } 
} 
getFormItems(); 
</script> 

Hope that helps.
