javascript - How can I use HTML5 geolocation in angularjs

Question

How can I use HTML5 geolocation in angularjs? I can get it using HTML5; but how can I pass it to angularjs scope in controller? any sample jsfiddle will save my day!

I'd suggest abstracting this into a service so your controller doesn't have a dependency on window.navigator, and to avoid the unnecessary use of $scope.$apply(). Here's what I'm using in my project:

angular.module('app', []).factory('geolocationSvc', ['$q', '$window', function ($q, $window) {

    'use strict';

    function getCurrentPosition() {
        var deferred = $q.defer();

        if (!$window.navigator.geolocation) {
            deferred.reject('Geolocation not supported.');
        } else {
            $window.navigator.geolocation.getCurrentPosition(
                function (position) {
                    deferred.resolve(position);
                },
                function (err) {
                    deferred.reject(err);
                });
        }

        return deferred.promise;
    }

    return {
        getCurrentPosition: getCurrentPosition
    };
}]);

Then I consume it in my controller like this:

function captureUserLocation() {
    geolocationSvc.getCurrentPosition().then(onUserLocationFound);
}
