Hi,
Ajax.Updater (and the rest) don't claim to post object graphs to the
server, and in fact they don't. They only pass name-value pairs,
because they're doing normal HTTP GETs or POSTs, which are based on
name-value pairs. HTTP doesn't know anything about JSON.
If you want to pass an object graph, you could pass a single parameter
with your JSON-formatted data as the value:
new Ajax.Updater(this.msg, '/inc/Calendar/Validate.php',
{
'parameters': {json: this.toJSON()}
}
);
...and then decode the JSON-formatted data (the value of the 'json'
parameter) on the server. There are JSON libraries for most server-
side languages (and if there isn't one that suits your environment,
well, the point of JSON is that it is easily parsed -- see json.org
for details).
HTH,
