Paul Stanton updated TAPESTRY-2251:
-----------------------------------
Attachment: ButtonLinkRenderer2.java
java class
> 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
> Attachments: ButtonLinkRenderer2.java
>
>
> 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.
