Sam, you don't need no eval. This is all already handled by jQuery
itself, since you have defined 'json' for dataType.
You can simply access the properties of the returned (json) object literal:
success: function(json) {
alert( json.title );
}
As per JSON definition[1], the property names must be strings, you
therefore should leave them wrapped in quotes. I also read somewhere
that otherwise you can run into some strange problems (cannot find it
anywhere right now).
The property values can be one of the _javascript_ data types
string
number
object
array
boolean
null
i.e. only use quotes if you have a string.
HTH, Klaus
