[Proto-Scripty] Textarea as a container
I tried using a textarea as the container for Ajax.updater
without luck.
I presume I need to write the js to take the response and put it
in the textarea, but the API just doesn't give me enough detail
to use Ajax.request to do that.
The returned data is plain text.
A bit of assistance would be appreciated.

Re: [Proto-Scripty] Textarea as a container
From the top of my head and totally untested:
new Ajax.Request('http://url-you-want-to-request', {
onSuccess: function(transport) {
$('id-of-your-textarea').setValue(transport.responseText);
}
});

Yes, but ONLY* if the two URLs share a common host (and protocol). Google 'Same
Origin Policy' for more gory details.
