注意事项

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:partner>
</ecomm:business>

注意： 在 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.
