Anchor and Javascript

[eluser]SDSL[/eluser]
How would you add javascript action to your anchor helper?
since the anchor helper insert the full url path in-front of the javascript it becomes useless
For example

Code:

anchor("#",img(), "onclick='select_all();'");

becomes

Code:

< a href="http://localhost/index.php/#">< / a >

and

Code:

anchor("[removed]select_all()",img());

becomes

Code:

< a  href="http://localhost/index.php/[removed]select_all();"> < / a >

Thank you
