ButtonLinkRenderer overwrites onclick event handler
---------------------------------------------------
Key: TAPESTRY-2251
URL: https://issues.apache.org/jira/browse/TAPESTRY-2251
Project: Tapestry
Issue Type: Improvement
Components: Contrib
Affects Versions: 4.1.5
Reporter: Paul Stanton
Priority: Minor
i've started using the buttonlinkrenderer and have noticed that a neat trick i
use with direct link does not work with buttonlinkrenderer.
to have the user confirm their action before submitting a request, i add an
onclick event hander ie: onclick="return confirm('sure?');" this would be
called before the actual direct link href was called, and returning false would
cancel the request altogether.
as buttonlinkrenderer utilises the onclick attribute of the button, this trick
is not available with a buttonlinkrenderer.
is it possible to have buttonlinkrenderer append to any existing onclick
handler? so instead of:
onclick="window.location='/.....'"
can it render:
onclick="myscript;window.location='/.....'" where myscript is my onclick hander.
thx. paul.
