How to send additional data with an ajax response

Hello everyone,

we have a problem where we update some page with an ajax request, but need additional data to be sent with the ajax response. This additional data should then be consumed on the client side by an ajaxComplete event. Does anyone know how a Tapestry event method can return more than just getBody() in the response? We would need to return a response containing both the new body and a JSONObject for consumption.

Regards,
Daniel P.

Yep! I'd just add the attributes to some existing HTML element

That's the method Tapestry 5.4 itself uses.

Yes, but then your response would be big anyway, data in HTML attributes  
or in a JSON object.

Data attributes are attributes like any other. IE9's JavaScript may not  
provide direct support for reading them, but jQuery and other JavaScript  
frameworks will cover that for you.

Hello again,

ah, of course I forgot to mention that our code should run in IE9, sadly. (I wouldn't prefer that). And IE9 doesn't seem to support data attributes.

Hello,

sorry, when I wrote the question I had totally forgotten about your post.
So you mean the HTML5 method of having, for example, a div element like this:
<div data-additionalData="myData"> ?

If you meant that, I haven't used this method yet for anything. Wouldn't that bloat the sent source if the additionalData is a big JSONArray? (I do not know anything about data tags yet, will inform myself)

Have you even considered my suggestion of using data tags inside the rendered HTML to provide the data?

I haven't checked out all of the callback types, but we often use the
javascript callback to do extra stuff on the calling page.

Something like:

ajaxResponseRenderer.addCallback( new JavaScriptCallback()
{
    @Override
    public void run( JavaScriptSupport javascriptSupport )
    {
        javascriptSupport.require( "<module-name>" ).invoke(
"<method-name>).with(
<data-to-return-must-match-invoked-module-method-signature);
    }
} );

This does not plug into the ajax complete event, but will be executed as
part of the call returning. There is a json callback as well, but I have
not looked into what is supposed to receive its return data.

Hello,

do you have example code returning not only the body, but also additional data, for me?

Daniel

Ajax response renderer may also be a viable solution for returning multiple things. I tend to prefer that over returning getBody() for exactly that reason.

Why don't you use data attributes in the returned HTML instead?
