Angular vs XMLHttpRequest

HTML

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<div ng-app>
    <div ng-controller="ghostController">
        <h4>Status:</h4>
        <div>
            through the object(angular): <code>r.status = '{{r.status}}'</code> (type={{type(r.status)}}) <br/>
            through the scope method call to object(javascript): <code>sfunction() = '{{sfunction()}}'</code> (type={{type(sfunction())}}) <br/>
            through the wrapper(angular): <code>d.r.status = '{{d.r.status}}'</code> (type={{type(d.r.status)}}) <br/>
            through the wrapper property(angular): <code>d.s = '{{d.s}}'</code> (type={{type(d.s)}}) <br/>
            through the wrapper method call(javascript): <code>d.smethod() = '{{d.smethod()}}'</code> (type={{type(d.smethod())}})<br />
            through the scope method call to wrapper(javascript): <code>dfunction() = '{{dfunction()}}'</code> (type={{type(dfunction())}})
        </div>
        <h4>XHR:</h4>
        <div>
            the culprit: <code>r = '{{r}}'</code> (type={{type(r)}}) <br/>
            immediate: <code>s = '{{s}}'</code> (type={{type(s)}}) <br/>
            indirect: <code>d = '{{d}}'</code> (type={{type(d)}}) <br/>
        </div>
    </div>
</div>

JavaScript

function ghostController($scope, $log) {
    
    function smethod() { return this.r.status; }
    
    $scope.r = new XMLHttpRequest();
    $scope.s = $scope.r.status;
    $scope.d = {r: $scope.r, s: $scope.r.status, smethod: smethod};
    $scope.type = function(value) { return typeof(value);}
    $scope.sfunction = function() { return $scope.r.status; }
    $scope.dfunction = function() { return $scope.d.r.status; }
    
    $.ajax({
        url:'http:/undefined.html',
        success: function() {$log.log('success');},
        error: function(result) {
            $log.log(result.status);
            $scope.r = result;
            $scope.s = $scope.r.status;
            $scope.d = {r: $scope.r, s: $scope.r.status, smethod: smethod};
            $scope.$apply();
        },
    });
}
