[AngularJS Gems] Few tips & tricks which allows you to get access to AngularJS "hidden" objects #javascript #angular

angular_tips.js

// Get access to a service. You can even execute service's methods afterwards:
angular.element('selector').injector().get('ServiceName');

// Access dom element scope:
angular.element('selector').scope();

// Access dom element isolated scope:
angular.element('selector').isolateScope();

// Access a controller:
angular.element('selector').controller();

// Injector allows you access to dependency injected components ('ng' is the umbrella module dependency for built-in services)
var $injector = angular.injector(['ng']);
//or
angular.injector(['ng']).get('$http')

angular_watchers.js

(function () { 
    var root = angular.element(document.querySelector('[ng-app],[data-ng-app]')),
      watchers = [],
      watchersWithoutDuplicates = [],
      f;

    //Watchers deep  search function:
    f = function (element) {
        angular.forEach(['$scope', '$isolateScope'], function (scopeProperty) { 
            if (element.data() && element.data().hasOwnProperty(scopeProperty)) {
                angular.forEach(element.data()[scopeProperty].$$watchers, function (watcher) {
                    watchers.push(watcher);
                });
            }
        });

        angular.forEach(element.children(), function (childElement) {
            f(angular.element(childElement));
        });
    };

    // Execute watcher search:
    f(root);

    // Remove duplicate watchers:
    angular.forEach(watchers, function(item) {
        if(watchersWithoutDuplicates.indexOf(item) < 0) {
             watchersWithoutDuplicates.push(item);
        }
    });

    console.log('There are %d watchers in your document (%s)', watchersWithoutDuplicates.length, document.title);
})();
