Firebug says my test data is an object, containing a object called
results. I changed the above (so I could inspect it) to:
var data =
{results:
[
{name: "Ron Savage", email: "[EMAIL PROTECTED]", phone: "0", id: "01"},
{name: "Zoe Savage", email: "[EMAIL PROTECTED]", phone: "9", id: "09"}
]
}
var json_data = new YAHOO.util.LocalDataSource(data);
That OK.
But what comes back from the Ajax call is displayed in red with ""
around it, i.e. it is a string, with the content being what I expect:
"{"results":[{"email":"[EMAIL PROTECTED]","name":"Ron
Savage","id":"3","phone":"0421920622"},{"email":"[EMAIL PROTECTED]","name":"Zoe
Savage","id":"4","phone":"95448128"}]}"
Sure the keys are quoted, but that's not the problem.
So how do I convert the string into a JS object?

It's truely impressive.
