[daisy] General Ajax form question

[Victor Oomens]

Hi guys,

Here's an update on my progress with ajax forms, for anyone who's interested.

It's actually very simple.

What you have to do with apples is this:

After the form post (with ajax), do normal form processing in the apple.
Now here's the trick: when the form validates, and you want to 'continue' to another page, send a custom browser update xml document as response to the ajax post. The document must contain:

<bu:document>
  <bu:continue/>
</bu:document>

This triggers a second post, but this time as non-ajax. You can detect this non-ajax post in the apple and ... well, figure it out.

Cheers!

Victor.

Hi guys,

Thanks for the help.

I've found a way to do a redirect after an ajax submit. It's not very elegant, but it works for now. I didn't want to use flowscript or javaflow and wanted to stick with the apples.

I've uses a hidden field widget in the form called 'saved', initially set to false.
After the apple processes and saves the form, I set the value of this widget to true and send the ajax response.
In the form template, I've used dojo.event.connect to attach an event handler to BUHandler.processResponse.
Within this handler, I read the value of 'saved'. When this value is true, I use document.location.href to redirect the browser.

Hopefully I may find a better solution in the future.

Kind regards,

Victor

This seems more like a general Ajax (or CForms?) question than a Daisy
question, but here's my shot in the dark:

Try handling the redirect in the browser.  To do this, include an
element in your xml response like this:
<redirectTo>/path/to/thankyou.html</redirectTo>

On the client side, handle the response and set document.location to
whatever is found in the redirectTo-element.

HTH,
Karel
