lastChild	Gets a reference to the last child in the childNodes collection of an object.
lastElementChild	Retrieves a reference to the last child element or null if there are no child elements.
localName	Retrieves the local name of the fully qualified XML declaration for a node.
name	Sets or retrieves the name of the object.
namespaceURI	Retrieves the namespace URI of the fully qualified XML declaration for a node.
nextElementSibling	Retrieves a reference to the sibling element that immediately follows or null if the element does not have any sibling elements that follow it.
nextSibling	Retrieves a reference to the next child of the parent for the object.
nodeName	Gets the name of a particular type of node.
nodeType	Retrieves the type of the requested node.
nodeValue	Gets or sets the value of a node.
ownerDocument	Retrieves the document object associated with the node.
ownerElement	Retrieves the element that owns the attribute.
parentNode	Retrieves the parent object in the document hierarchy.
prefix	Retrieves the local name of the fully qualified XML declaration for a node.

Remarks

The attribute object is accessible through the attributes collection.

A valid attribute or property can be any Dynamic HTML (DHTML) property or event that applies to the object, or an expando.

Examples

This example uses the attribute object to create a list of attributes that are specified.


<script type="text/javascript">
function fnFind(){
   var oList = document.getElementById("myList");
   for(var i=0;i<oList.attributes.length;i++){
      if(oList.attributes[i].specified){
         console.log(oList.attributes[i].nodeName + " = "
          + oList.attributes[i].nodeValue);
      }
   }
}
</script>
<ul onclick="fnFind()">
<li id = "myList" accesskey = "l">List Item 1
</ul>
