 var arrElems = myForm.elements;
 if (!arrElems)
  return;
  
    // Reset all input fields   
    for( var i = 0 ; i < arrElems.length ; i++){

  switch (arrElems[i].type.toLowerCase()) {
   case  "text":
   case  "password":
   case  "textarea":
    arrElems[i].value="";
    break;
   case  "radio":
   case  "checkbox":
    arrElems[i].selected = false;
    arrElems[i].checked = false;
    break;
   default:
    arrElems[i].selectedIndex = 0;
