readAttribute :: Element |
This method serves two purposes. First it acts as a simple wrapper around getAttribute which isn't a "real" function in Safari and Internet Explorer (it doesn't have .apply or .call for instance). Secondly, it cleans up the horrible mess Internet Explorer makes when handling attributes.
Examples
<a id="tag" href="/tags/prototype" rel="tag" title="view related bookmarks." my_widget="some info.">Prototype</a>
$('tag').readAttribute('href'); // -> '/tags/prototype'
$('tag').readAttribute('title'); // -> 'view related bookmarks.'
$('tag').readAttribute('my_widget'); // -> 'some info.'
