S2: submit tag and handler
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

Ahh, notifyTopics. Sweet, sweet, notifyTopics.
I guess the reason I did not use notifyTopics before
is that I did not understand it. I now have the
"before" working great, and as soon as I figure out
how to indicate success in the action (guess it is not
just return SUCCESS;) I am sure the "load" will work
fine, too.
Thanks again for the help, Musachy.

I should have asked this first, if all you want to do is do something before
the request, why don't you use "notifyTopics"?

Well, I tried this:
function handler(widget, node)
{
var beforeTopicsArray =
widget.beforeNotifyTopicsArray;
widget.beforeNotifyTopicsArray = null;
widget.reloadContents();
widget.beforeNotifyTopicsArray = beforeTopicsArray;
}
and now I do not get a stack overflow, but the action
is still not getting called.

Re: S2: submit tag and handler
Posted by Musachy Barroso <mu...@gmail.com>.
My bad, the notifyTopics are published inside that function so it won't
work. Warning: Hack ahead :)
var beforeTopicsArray = widget.beforeNotifyTopicsArray;
widget.beforeNotifyTopicsArray = null;
widget.reloadContents();
widget.beforeNotifyTopicsArray = beforeTopicsArray;
I will add a "refreshContent" method that will be common for all of the
widgets (and part of the api), with one parameter(boolean), to skip the
publishing of the topics.

Re: S2: submit tag and handler

Hmm, this:
function handler(widget, node)
{
widget.reloadContents();
}
Gives "Stack overflow at line: 4872"

Re: S2: submit tag and handler
Posted by Musachy Barroso <mu...@gmail.com>.
If you are using submit, or anchor tag you can call "reloadContents()" on
the widget passed as a parameter, if you are using the div tag, you can call
"refresh()" on it. These functions are not really part of the api and might
change in the future (although it would be nice if they were right?).

Re: S2: submit tag and handler
Posted by Scott Nesbitt <sc...@yahoo.com>.
Yes, I would like to do the request in the JavaScript
because I need to do some other work there before the
request happens.
If I knew how Struts did the request I would just do
the same thing at the bottom of my function.

Re: S2: submit tag and handler
Posted by Musachy Barroso <mu...@gmail.com>.
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
}
