Node.localName

Deprecated

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The Node.localName read-only property returns the local part of the qualified name of this node.

In DOM4 this API was moved from Node to the Element and Attr interfaces.

Syntax

name = element.localName
  • name is the local name as a string (see Notes below for details)

Example

(Must be served with XML content type, such as text/xml or application/xhtml+xml.)

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:svg="http://www.w3.org/2000/svg">
<head>
  <script type="application/javascript"><![CDATA[
  function test() {
    var text = document.getElementById('text');
    var circle = document.getElementById('circle');

    text.value = "<svg:circle> has:\n" +
                 "localName = '" + circle.localName + "'\n" +
                 "namespaceURI = '" + circle.namespaceURI + "'";
  }
  ]]></script>
</head>
<body onload="test()">
  <svg:svg version="1.1"
    width="100px" height="100px"
    viewBox="0 0 100 100">
    <svg:circle cx="50" cy="50" r="30" style="fill:#aaa" id="circle"/>
  </svg:svg>
  <textarea id="text" rows="4" cols="55"/>
</body>
</html>

Notes

The local name of a node is that part of the node's qualified name that comes after the colon. Qualified names are typically used in XML as part of the namespace(s) of the particular XML documents. For example, in the qualified name ecomm:partners, partners is the local name and ecomm is the prefix:

<ecomm:business id="soda_shop" type="brick_n_mortar" xmlns:ecomm="http://example.com/ecomm">
  <ecomm:partners>
    <ecomm:partner id="1001">Tony's Syrup Warehouse
    </ecomm:partner>
  </ecomm:partners>
</ecomm:business>

Note: In Gecko 1.9.2 and earlier, the property returns the upper-cased version of the local name for HTML elements in HTML DOMs (as opposed to XHTML elements in XML DOMs). In later versions, in compliance with HTML5, the property returns in the case of the internal DOM storage, which is lower case for both HTML elements in HTML DOMs and XHTML elements in XML DOMs. The tagName property continues to return in the upper case for HTML elements in HTML DOMs.

For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE localName is always null.
