The whole idea behind the "handler" function is that you are going to make
the request yourself, instead of letting struts do it for you. The handler
is just a plain javascript function like:
function superHandler(widget, domNode) {
//use some other framework to do the ajax request, Dojo, Prototype, YUI,
DWR, JQuery,....zillion_framework_name
}
is that what you are trying to do? do the request yourself?

Does anyone know how to invoke a request from a submit
handler function?
I am using a submit tag like this:
<div id="t1">Div 1</div>
<s:url id="ajaxTest" value="SaveLineup.action" />
<img id="indicator"
src="images/indicator.gif"
alt="Loading..."
style="display:none"/>
<s:submit type="submit"
theme="ajax"
value="Save"
title="Save all changes."
cssClass="butstylewide"
targets="t1"
handler="handler"
notifyTopics="/after"
href="%{ajaxTest}"
align="left"
indicator="indicator"/>
My Javascript looks like this:
function handler(widget, node)
{
alert("DEBUG in handler");
}
dojo.event.topic.subscribe("/after", function(data,
type, e)
{
alert("Lineup saved");
});
The documentation says this:
'handler' is the name of the function that will take
care of making the AJAX request. Dojo's widget and dom
node are passed as parameters).
But I do not see any example of how to actually do
that. I guess it is some Dojo magic but looking
through the Dojo documentation has not proved
illuminating. (BTW, I know if I do not have handler
specified it calls the action but I need to do some
JavaScript work beforehand.)
Thanks,
Scott
