[jQuery] JSON Serializer

[jQuery] JSON Serializer


I'm having an issue using an asmx web service to return json to a
jQuery ajax call. If I run the web service stand alone i get a nice
json response as follows:
<string>
{"City":"nyc","Country":"usa","PostalCode":null,"State":null,"Street":null}
</string>
I'm using the DataContractJsonSerializer in .NET to create this json.
When I call this web service from a $.ajax call I can't get at the
values of the json object and i notice in firebug that the response is
now :
{"d":"{\"City\":\"nyc\",\"Country\":\"usa\",\"PostalCode\":null,\"State
\":null,\"Street\":null}"}
Here is my jQuery call:
$.ajax({
url: '/webservices/WebService2.asmx/HelloWorldJson',
dataType: 'json',
type: 'post',
error: function(req, textStatus, errorThrown){alert('error
loading response: ' + textStatus);
},
beforeSend: function(xhr){
xhr.setRequestHeader("Content-type","application/json;
charset=utf-8");
},
success: function (d) {
//var customers = eval("(" + d + ")");
//alert(customers.Country);
alert(d);
validateUsername.html(d.country);
}
});
but i can never get at the values of the json object that is returned
for some reason. What am i doing wrong?
