ANGULARJS: TYPESCRIPT – USING DIRECTIVE FOR FOCUS

import angular = require('angular');
/* @ngInject */
export class SetFocus implements angular.IDirective {
  private $log: angular.ILogService;
  publicstaticFactory(): angular.IDirectiveFactory {
    return () = >newFocus();
  }
  publiclink:angular.IDirectiveLinkFn = (scopeS: angular.IScope, elementS: JQuery, attrsS: angular.IAttributes) => {
    if (!this.$log) {
      this.$log=angular.injector(['ng']).get('$log');
    }
    if (attrsS.focus==='true') {
      elementS[0].focus() ;
    }
    scopeS.$on(attrsS.focus, (e) => {
    elementS[0].focus();
    });
  }
};
// Remove on Angular 2
require('../../operations.module')
.directive('setFocus', () => new SetFocus());

$scope.addNewItem = function () {
    /* stuff here to add a new item... */

    $scope.$broadcast('newItemAdded');
};

<input type="text" focus-on="newItemAdded" />
