Hi Igor,
you mean
onclick=
myVar = 'some value';
wicketAjaxGet(this.getCallbackUrl()+variableName='myVar');
/*start of java processing in the backend*/
protected void respond(final AjaxRequestTarget target) {
Component component = getComponent();
Request request;
if (component != null (request = component.getRequest()) !=
null) {
String variableName =
request.getParameter(variableName);
target.appendJavascript(variableName='some OTHER
value';);
}
//should now be 'some OTHER value' but is still 'some value'
alert('myVar = ' + myvar);
This does not work. The javascript that was appended to the target gets
evaluated AFTER the alert call.
Or did I miss something?

append the name of the variable to the url, in target generate js that
sets the variable to the value. after wicketajaxget processes the
result the value should be set

Hi Vineet,
that's true. I already know this but this is not what I need. I need the
opposite thing. What you explained is something like an input parameter to
wicketAjaxGet. This input parameters can easily be fetches from the Request.
But what I need is a return value for wicketAjaxGet. That is visible in the
javascript code AFTER doing something in respond.
This means
Have some javascript on the page like
var result = wicketAjaxGet(...)someParameter...;
// do the respond() mehtod processing on the javaside and return a
value
alert('result of respond processing' = result);

Hi,
take a look at
http://cwiki.apache.org/WICKET/calling-wicket-from-javascript.html
following is what you need to do ..
you can concatenate the value you want to return as paramter in
callbackurl,we will read this back as request
parameter from java.
it should look like callbackurl++component markupid+=+args;
then in your respond method you can easily read request parameter from url .
String paramFoo = RequestCycle.get().getRequest().getParameter(component
markupid);

If I place a call to wicketAjaxGet(...) into a eg.g onclick attribute
with the help of an AjaxBehavior, the method respond(final
AjaxRequestTarget target) is called on the Java side.
Is it possible to build a call to wicketAjaxGet like
var result = wicketAjaxGet(...);
and provid the result value in the respond method on the Java side?
Does anobody know the trick?
