Applying attributes to children or a span

I have a table with form elements in it wrapped in a span, and I have it so you can toggle whether the span displays or not through an onclick of a title. I also have a function that validates all the form fields to ensure that no value of "" is entered, but I want it to ignore the fields if they are not being displayed. My validation is as such:


function validate_forms()
{
 
 for ( i = 0; i < document.forms.length; i++)
 {
 elements = document.forms[i]; for( n = 0; n < elements.length ; n++)
 {
  if ( elements[n].name == "req" && elements[n].value == "")
  {
  elements[n].focus();
  return false;
  }
 } }
 return true;
}

I have tried adding things such as " && if ( elements[n].currentStyle.display!= "none")", but in the code I use to hide elements


span.style.display = "none";

does not apply to the elements wrapped in the span. Is there a way to either make it apply to everything within it or to check the value of the span in way of a property of the element?

For example, something like this would be optimal:

if elements[n].parentspan.style.display!= "none"

span.style.display = "none";
for ( i = 0; i < span.childNode.length ; i++)
span.childNode[i].display = "none"l;

Thanks in advance.
