Currently I have no simple example :-(
In my case (wicketstuff-jquery), I've got a link that call a javascript
function generated (with a template on server side).
In this function :
var wcall = wicketAjaxGet('${callbackUrl}&' +
DnDSortableBehavior.asQueryString(), function(){}, function(){});
And the method DnDSortableBehavior.asQueryString() is in charge of formated
collected state, params,...
var DnDSortableBehavior = {
...
asQueryString : function() {
return 'itemId=' + this.itemId + '&srcContainerId=' + this.srcContainerId +
'&srcPosition=' + this.srcPosition + '&destContainerId='+ this.destContainerId +
'&destPosition=' + this.destPosition;
}
};
In my case I use jquery to retrieve states, values.
If I've got time this evening, I'll try to create a sample.
Which type of information do you want to send back to server ?

i have traced the wicket source codes at the place that how it generates the
ajax js like
wcall=wicketAjaxGet('xxx')
but i don't know exactly what this does, so how to "add parameter" to the
wicket ajax request?
i can add custom js to the wicket ajax javascript, but how can I pass the
some dynamic js state into that ajax request, e.g. i trigger the ajax
request by a link with AjaxEventBehavior on onclick event.
would you mind show me a simple example?

For a similar case, I override (in MyBehavior)
@Override
public final void respond(AjaxRequestTarget target) {
try {
Request req = RequestCycle.get().getRequest();
String param1 = req.getParameter("param1");
// to stuff
super.respond(target); //??
} catch (RuntimeException exc) {
throw exc;
} catch (Exception exc) {
throw new RuntimeException("wrap: " + exc.getMessage(), exc);
}
}
And you need to override (server or client side) the callbackUrl to add
parameter.

How to pass information (stored in an attribute of a html tag, or
javascript
variable) through ajax without involving form?
e.g. there is an ajax link and after I click this ajax link, an ajax
event
is triggered and I want to get the states of other html
elements/javascript
states in this ajax event
it is no problem to use form, but we have a restriction that no form is
used
(may look weird to all here), so I would like to see if there is
workaround
in wicket.
