$inject Afhankelijkheid Injectie lijst, het wordt opgelost door hoekige en doorgeven als een argument voor constuctor functies.

Opmerkingen

Houd bij het uitvoeren van de richtlijn in TypeScript rekening met de kracht van deze taal van aangepast type en interfaces die u kunt maken. Dit is zeer nuttig bij het ontwikkelen van grote applicaties. Code-aanvulling ondersteund door veel IDE zal u de mogelijke waarde laten zien per overeenkomstig type waarmee u werkt, dus er is veel meer dat in gedachten moet worden gehouden (vergeleken met VanillaJS).

"Code tegen interfaces, geen implementaties"

Richtlijn

interface IMyDirectiveController {
    // specify exposed controller methods and properties here
    getUrl(): string;
}

class MyDirectiveController implements IMyDirectiveController {

    // Inner injections, per each directive 
    public static $inject = ["$location", "toaster"];

    constructor(private $location: ng.ILocationService, private toaster: any) {
        // $location and toaster are now properties of the controller
    }

    public getUrl(): string {
        return this.$location.url(); // utilize $location to retrieve the URL
    }
}

/*
 * Outer injections, for run once controll. 
 * For example we have all templates in one value, and we wan't to use it.
 */
export function myDirective(templatesUrl: ITemplates): ng.IDirective {
    return {
        controller: MyDirectiveController,
        controllerAs: "vm",

        link: (scope: ng.IScope,
               element: ng.IAugmentedJQuery,
               attributes: ng.IAttributes,
               controller: IMyDirectiveController): void => {

            let url = controller.getUrl();
            element.text("Current URL: " + url);

        },

        replace: true,
        require: "ngModel",
        restrict: "A",
        templateUrl: templatesUrl.myDirective,
    };
}

myDirective.$inject = [
    Templates.prototype.slug,
];

// Using slug naming across the projects simplifies change of the directive name
myDirective.prototype.slug = "myDirective";

// You can place this in some bootstrap file, or have them at the same file
angular.module("myApp").
    directive(myDirective.prototype.slug, myDirective);

Eenvoudig voorbeeld

export function myDirective($location: ng.ILocationService): ng.IDirective {
    return {

        link: (scope: ng.IScope,
            element: ng.IAugmentedJQuery,
            attributes: ng.IAttributes): void => {

            element.text("Current URL: " + $location.url());

        },

        replace: true,
        require: "ngModel",
        restrict: "A",
        templateUrl: templatesUrl.myDirective,
    };
}

// Using slug naming across the projects simplifies change of the directive name
myDirective.prototype.slug = "myDirective";

// You can place this in some bootstrap file, or have them at the same file
angular.module("myApp").
    directive(myDirective.prototype.slug, [
        Templates.prototype.slug,
        myDirective
    ]);

bestanddeel

Voor een gemakkelijkere overgang naar Angular 2 wordt het aanbevolen om Component te gebruiken, beschikbaar sinds Angular 1.5.8

myModule.ts

import { MyModuleComponent } from "./components/myModuleComponent";
import { MyModuleService } from "./services/MyModuleService";

angular
    .module("myModule", [])
    .component("myModuleComponent", new MyModuleComponent())
    .service("myModuleService", MyModuleService);

componenten / myModuleComponent.ts

import IComponentOptions = angular.IComponentOptions;
import IControllerConstructor = angular.IControllerConstructor;
import Injectable = angular.Injectable;
import { MyModuleController } from "../controller/MyModuleController";

export class MyModuleComponent implements IComponentOptions {
    public templateUrl: string = "./app/myModule/templates/myComponentTemplate.html";
    public controller: Injectable<IControllerConstructor> = MyModuleController;
    public bindings: {[boundProperty: string]: string} = {};
}

templates / myModuleComponent.html

<div class="my-module-component">
    {{$ctrl.someContent}}
</div>

controller / MyModuleController.ts

import IController = angular.IController;
import { MyModuleService } from "../services/MyModuleService";

export class MyModuleController implements IController {
    public static readonly $inject: string[] = ["$element", "myModuleService"];
    public someContent: string = "Hello World";

    constructor($element: JQuery, private myModuleService: MyModuleService) {
        console.log("element", $element);
    }

    public doSomething(): void {
        // implementation..
    }
}

diensten / MyModuleService.ts

export class MyModuleService {
    public static readonly $inject: string[] = [];

    constructor() {
    }

    public doSomething(): void {
        // do something
    }
}
