title: Get value from JSON string
body: <p>I have the following JSON string:</p>
  
  <pre><code>{"d":"{\"Foo\":7,\"Bar\":5,\"Foobar\":3}"}
  </code></pre>
  
  <p>And the corresponding invocation in my js file:</p>
  
  <pre><code>$.getJSON("Foo.svc/GetSomeFoo", function (response) {
              alert(response["Foo"]);
              alert(response["Bar"]);
              alert(response["Foobar"]);
          });
  </code></pre>
  
  <p>Just trying to write out the values, but can't seem to get it out.
  It is probably very simple, but I am not finding anything helpful while googling it.</p>
