NamedNodeMap

DOM Level 3

For technical reasons, the title of this article is not the text used to call this API. Instead, use DOM Level 3

Summary

A collection of nodes that can be accessed by name. Objects contained in a NamedNodeMap may also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents of a NamedNodeMap, and does not imply that the DOM specifies an order to these nodes.

Properties

No properties.

Methods

getNamedItem

Gets an attribute with a given name from an element.

getNamedItemNS

Gets an attribute with a given name and a given namespace.

removeNamedItem

Removes an attribute with a given name.

removeNamedItemNS

Removes an attribute with a given name and a given namespace.

setNamedItem

Adds an attribute to an element by using an attributes collection.

setNamedItemNS

Sets an attribute object as part of the object.

Events

No events.

Examples

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

<script type="text/javascript">
function fnFind(){
   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 = "oList" accesskey= "L">List Item 1</li>
</ul>

Notes

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. 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.
