I am trying to extract the meta-information(title, image) from URL and display it like facebook. I have read some documents and written this code. Since i am new in angular. I dont get it where i am doing wrong

var myApp=angular.module('myApp',[]);
function MyCtrl($scope,$http){      
    $http.get('www.socialorra.com').
    success(function(data,status,headers,config){
        $scope.url=$(data).filter('meta[name=title]').attr("content");  
    }).
    error(function(data,status,headers,config){

    }); 
}
