Parsing json

Hi,

I have a service call in my application which returns jsaon data. The call is like so:

            $.ajax({
                type: "GET",
                dataType: "json",
                url: 'http://rest.smartdoc.se/api/users/' + username + '/' + password,
                success: function (Data) {
                    var obj = $.parseJSON(Data);
                    alert(obj.FullName);
                }

            });

Open in new window

The service returns this:

{"Data":[{"FullName":"Doesn't exist","username":"sdf","password":"sdf"}],"Errors":null}

Open in new window

There obviously is something wrong because it is not working. Please help me.

Best regards

Actually, no - you need this:

success: function (Data) {
    var person = Data.Data[0]; //grab the first person from the Data array
    alert(person.FullName);
}

Open in new window

The Data returned contains a Data key, holding an array or people. If you are likely to be passing back more than one person then you'll need to loop through Data.Data

why :
url: 'http://rest.smartdoc.se/api/users/' + username + '/' + password,

and not :
url: '/api/users/' + username + '/' + password,

Hi,

The application is running on a smartphone. I need to provide the complete url to the service which is running on a web server. The call to the service works fine and it returns the desired json. My problem is just to parse it.

Look at your JSON, you probably need this:

var obj = $.parseJSON(Data);
alert(obj.Data.FullName);

Well... I looked at your code and really bad is this line:

'http://rest.smartdoc.se/api/users/' + username + '/' + password

You're passing username and password in clear text and not even https?
And I hope you're not doing this for each request...
