false (and true) and numbers are valid JSON values. You *can* put them in
quotes, but that changes their meaning: they become strings instead of
boolean or numeric values.
It's true that you would want to use the properties of the msg object such
as msg.descrizione, but it's also fine to call alert(msg). It should alert
this text:
[object Object]
I wouldn't use msg as the variable name, since that sounds like an
abbreviation for "message" - and this is an object, not a message string.
But that wouldn't affect how the code works.
That said, it's pretty hard to tell what might be wrong.
Luca, I assume that the line break between "del" and "computer" is not
present in the actual JSON text, but is simply an artifact introduced in the
email post, is that correct?
Can you post a link to a test page that demonstrates the problem? That would
make it much easier (i.e. it would make it *possible*) to help you.
