parse JSON URL

HI All,

I am unable to parse the JSON URL. The following is the code snippet :

<script src="//code.jquery.com/jquery-1.10.2.js"></script>

<script>

var getUrl = "http://api.openweathermap.org/data/2.5/weather?q=london";

$.ajax({

         url : getUrl,

         type : 'GET',

         dataType : 'json',

         crossDomain : true,

         success: function(data) {

         alert('sucess');

          alert(JSON.parse(edata));

         },                                                                                                                                                                                      

         error: function() {

          alert('error');

         }

     });

</script>

It is alerting with sucess message but unable to parse the json data. Please suggest the way forward.
