select element by onclick event?

select element by onclick event?

I need to take the link away where the onclick contains 'return listItemTask'.
Preferably leaving whatever is in the link intact.
<a href="javascript:void(0);" onclick="return listItemTask('cb0','unpublish')">
      <img src="images/tick.png" />
</a>


how to do that?

I tried:
$("input[onclick^='return listItemTask']").html("taken_out");

which does nothing
