以下示例演示了 parentNode 属性的用法 −

<!DOCTYPE html>
<html>
   <body>
      <script>
         if (window.XMLHttpRequest) {
            xmlhttp = new XMLHttpRequest();
         } else {
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
         }
         xmlhttp.open("GET","/dom/node.xml",false);
         xmlhttp.send();
         xmlDoc = xmlhttp.responseXML;
         document.write("Parent node of Employee is: ");
         x = xmlDoc.getElementsByTagName("Employee")[0];
         document.write(x.parentNode.nodeName);
      </script>
   </body>
</html>
