Properties

The attribute object has these properties.

Property	Description
childElementCount	Retrieves the number of immediate child nodes of the current element or a zero if the element does not contain any child nodes. childElementCount does not return all child nodes, only child nodes that are nodeType =1, or element nodes.
constructor	Returns a reference to the constructor of an object.
expando	Sets or retrieves a value indicating whether arbitrary variables can be created within the object.
firstChild	Gets a reference to the first child in the childNodes collection of the object.
firstElementChild	Retrieves a reference to the first child element, or null if there are no child elements.
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.
previousElementSibling	Retrieves a reference to the immediately preceding sibling element or null if the element does not have any preceding siblings.
previousSibling	Gets a reference to the previous child of the parent for the object.
specified	Gets a value that indicates whether an attribute is explicitly given a value.
textContent	Sets or retrieves the text content of an object and any child objects.

Standards information

There are no standards that apply here.

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.

When displaying a Web page in IE8 Standards mode, Windows Internet Explorer distinguishes between attribute values specified by the original page author and the representation of those values in the DOM. For more information, see Attribute Differences in Internet Explorer 8.

This object is available in script as of Microsoft Internet Explorer 5.

Examples

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

JavaScript


<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){
         alert(oList.attributes[i].nodeName + " = "
          + oList.attributes[i].nodeValue);
      }
   }
}
</script>
<ul onclick="fnFind()">
<li id = "myList" accesskey = "l">List Item 1
</ul>
