IHeaderResponse.renderOnUnLoadJavascript(String javascript);
------------------------------------------------------------
Key: WICKET-480
URL: https://issues.apache.org/jira/browse/WICKET-480
Project: Wicket
Issue Type: New Feature
Components: wicket
Affects Versions: 1.3
Reporter: Martin Funk
Priority: Minor
Where there is a renderOnLoadJavascript there ought to be a
renderOnUnLoadJavascript too.
This is all just copy past, so it's a little smelly.
Beyond that I wouldn't mind to be able to specify which element an event should
be added.
