hasAttributes (W3C DOM Core method)
| Version | Depr. | Static |
|---|---|---|
| DOM2 | No | No |
| IE7 | FF1.5+ | SA1.3+ | OP9+ |
|---|---|---|---|
| None | Full | Full | Full |
- Returns
Boolean
Example
var hasattrs = node.hasAttributes();
In the example above, the variable hasattrs will have
the value true if node is an element
and has any attributes, otherwise it will be
false.
So in this next HTML example, if
node were the first paragraph then hasAttributes would return true. But if
node were the second paragraph, which has no
attributes, then hasAttributes would return
false:
<p id="first"><q>I am the eggman</q></p> <p><q>I am the walrus</q></p>
Description
Returns whether an Element node has any attributes.
Return value
Returns
true if this node is an Element
and has any effective attributes, otherwise false
Compatibility

Internet Explorer doesn't implement this method, and will throw an error if it's used.
Internet Explorer,
Firefox, Safari
and Opera 9.5 do not include attributes
which are not explicitly defined but have a specific default value in
this document type, such as the shape attribute
of an <a> element (only Opera
9.0 does so).
However for this method, the specification does not actually say whether it means any effective attributes1, or merely explicitly-defined attributes. I suspect that it intended to mean effective attributes, but in the absence of specification this behavior cannot be considered a bug.
