[FIXED] Why can't I access these JSON values?

Issue

In one of my web pages I am making an AJAX call to retrieve a member's profile properties so that they can make changes. The code being used to do this is as so:

        function loadProfileData() {
            var request = $.ajax({
                url: "../handlers/getprofile.ashx",
                method: "POST"
            });

            request.done(function (msg) {
                if (msg.Success == false) {
                    $('#spnProfileErr').html(msg.Status);
                    $('#toastProfileFail').toast('show');
                }
                else {
                    $('#lastname').val(msg.MemberProfile.LastName); // textbox
                    $('#firstname').val(msg.MemberProfile.FirstName); // textbox
                    $('#bestemail').val(msg.MemberProfile.BestContactEmail); // textbox
                    $('#agerange').val(msg.MemberProfile.AgeRange);  // select control
                    $('#zipcode').val(msg.MemberProfile.ZIPCode); // textbox
                }  
            });

            request.fail(function (jqXHR, textStatus) {
                $('#spnProfileErr').html('Unable to retrieve your existing profile at this time.');
                $('#toastProfileFail').toast('show');
            });
        }

The call to the web service works just fine, and it returns a JSON String, as follows:

I can access the 'Success' and 'Status' properties of the returned JSON, but when I try to access the member profile properties of the MemberProfile in the JSON, it doesn't let me. For example, accessing msg.MemberProfile.LastName throws an undefined error.

What am I not doing right?

Solution

Probably, you're receiving just a string, try use

var msg = JSON.parse(msg)

at beginning of your callback, so it will convert your string to a desired object, try out
