AngularJS - Directives - What's the reason behind the following syntax?


AngularJS - Directives - What's the reason behind the following syntax?

To fix this issue By convention the $ prefixes are not used with functions which are not injected by the $injector. So the link: function (scope, element, attrs [,ctrl]) will not be injected. It always has the same parameters in the same order.
When dealing with functions where the dependency injection provides the arguments, you must use $scope, otherwise it won't be injected.
code :
myModule.directive('directiveName', function factory(injectables) {
  var directiveDefinitionObject = {
    template: function(tElement, tAttrs) { ... },
    templateUrl: function(tElement, tAttrs) { ... },
    // controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
    compile: function compile(tElement, tAttrs, transclude) {
      return {
        pre: function preLink(scope, iElement, iAttrs, controller) { ... },
        post: function postLink(scope, iElement, iAttrs, controller) { ... }
      }
    },
    link: {
      pre: function preLink(scope, iElement, iAttrs, controller) { ... },
      post: function postLink(scope, iElement, iAttrs, controller) { ... }
    }
    // or
    link: function postLink(scope, iElement, iAttrs, controller) { ... }
  };
  return directiveDefinitionObject;
});
// ... somewhere in the DDO ...
controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },

AngularJS : Scope access between directives and transcluded directives

AngularJS : Scope access between directives and transcluded directives

help you fix your problem The ng-transclude directive always create a new child scope for the transcluded content.
There is a request here (https://github.com/angular/angular.js/issues/5489) to not create a new scope but it hasn't implemented yet.
code :
link: function(scope, element, attributes, controllers, transcludeFn){
  transcludeFn(scope, function(nodes) {
    element.find('.transclude-here').append(nodes);
  })
}
<div ng-transclude></div>
<div class="transclude-here"></div>
app.directive('myTransclude', function () {
  return {
    restrict: 'EAC',
    link: function(scope, element, attrs, controllers, transcludeFn) {
      transcludeFn(scope, function(nodes) {
        element.empty();
        element.append(nodes);
      });
    }
  };
});
 <div my-transclude></div>
AngularJS Controller as syntax and Directives

AngularJS Controller as syntax and Directives

like below fixes the issue So I have been exploring the Controller as syntax in AngularJS, and I want to know how to deal with directives and $scope, specifically inheritance of the controllers $scope or properties from a child directive. , In case we would declare as like this (inside of a View):
code :
<div ng-controller="DefaultController as Events">
 ...
export class MyDefaultDirective implements ng.IDirective
{
    public restrict: string = "E";
    public replace: boolean = true;
    ...
    public controller: string = "DefaultController as Events";
    ...
// this was done by angular
// - the 'as' part was used for a property name
// - current controller instance was injected 
var controller = this.$scope.Events;
export class DefaultController implements IDefaultController {
    // explicit public just to show that this will be available
    public customer: Models.ICustomer;
    ....

    getCustomerById(id: number): void {
        this.customerDataService.getCustomer(id).then((customer) => {

            // HERE
            // this.$scope.Events.customer is ready for use
            this.customer = angular.extend(new Models.Customer(), customer);
      ...
<div>
  {{Events.customer}} // public propeties of this.$scope

Any of those help You have 2 errors, that actually are sort of explained in the errors themselves.
First: travel-dt.js:45 Uncaught SyntaxError: Unexpected token . It's hard to tell exact row numbers, but looking at the provided code, your controller variable declared inside the directive function is missing one minification safe of flightservice. It should look like this
code :
var travelDtCtrl = ['$scope', 'flightService',
      function($scope, flightService) {
        $scope.flight = flightService;
<script src="js/flight-service.js"></script>
<script src="js/airport-search.js"></script>
<script src="js/travel-dt.js"></script>
<script src="js/app.js"></script>

should help you out
Now, if anyone could explain why "In directive " is logged only once. Controller is behaving as expected.
code :
<custom-heading></custom-heading>
<custom-heading></custom-heading>
<custom-heading></custom-heading>
