SubmitLink with confirmation dialog
Hi there,
I have a SubmitLink and I'd like to add a very simple confirmation dialog to
it? Any way of doing so?
I've tried to add a SimpleAttributeModifier, but it overwrites the behaviour
in the onSubmit method of the submitlink. I think there must be an easy and
clean way of doing this.
Thank you.--

Hi, SubmitLink already write some JavaScript in the onclick handler, so you
need to prepend the confirmation JavaScript in order to maintain the default
behavior. e.g.
submitLink.add(new Behavior() {
onComponentTag() {
tag.put("onclick", "if(!confirm('c')) return false;" +
tag.getAttribute("onclick"));
}
});
In Wicket 1.5 RC4 you can also use the AttributeAppender to prepend the
confirmation JavaScript.

Dear Martin,
thank you for answering. I tried something like this:
----------------------------------------------------------
SubmitLink link = new SubmitLink("link") {
public void onSubmit() { /* my stuff */}
}
link.add(new SimpleAttributeModifier("onclick", "return confirm('are you
sure?');"));
----------------------------------------------------------
However, weather I click 'Cancel' or 'OK', the code in the onSubmit() method
never gets executed.
I'm stuck, I can't believe such a framework does not support this basic
feature O_o I must be missing something obvious ^^"

SimpleAttributeModifier("onclick", yourJsHere) is the way if you want
to use JavaScript alert(). onSubmit() method is called at server side
only if onclick at the client side returned true.
