angular Js call function outside of given function

You need to return data from the $http.get call

 google.maps.event.addListener(marker, 'dragend', function() {
   getmydata = function() {
       return $http.get("getConnectionData.php").then(function (response) {
                 return response;
           });
       }

      getmydata().then(function(data) {
      // stuff is now in our scope, I can alert it
      $scope.links1 = data;
      console.log("hiiiii" , $scope.links1);
      });
 });

you can write something like this

   getmydata2=function(data){
      console.log("hiiiii" , data);
   }

   getmydata = function() {
        return $http.get("getConnectionData.php").then(function (response) {
                     $scope.links1 = response.data.records;
                     getmydata2($scope.links1);
               });

   }

 google.maps.event.addListener(marker, 'dragend', getmydata);

you can now call it wherever you want
