I am a prototype newbie and am unclear on how to process multiple json objects returned. For example I would like to return a simple JSONObject map indicating the success/failure and also return a JSONArray that I can index and build an select:options from. Now each json object will be upt in the header with a different name. How do I parse that out client-side and alert on a failure name/value else build the select:option element? tia.

Suppose your /someurl service sends a reply like this:
{
"status": "ok",
"data":["apples", "oranges", "bananas"]
}
What I have done here is to combine the two objects into a single object. In the client you can handle it something like this.
new Ajax.Request('/someurl', {
method:'get',
requestHeaders: {Accept: 'application/json'},
onSuccess: function(transport){
var json = transport.responseText.evalJSON();
if(json.status != 'ok')
{
alert('status "'+json.status+'" not ok')
return; // or throw a fit
}
json.data.each(function(elt){
alert(elt); // or display it, whatever
});
}
});
