I'm following the angular tutorial on the basics of Angular2, trying to translate it to javascript since it is currently only available for Typescript.
I currently have two files: app.component.js and hero-detail.component.js. Located in app.component.js i have my AppComponent. From this, I would like to load the component in hero-detail.component.js as a directive.
My current code looks like this, but I can't figure out how to load HeroDetailComponent:
app.AppComponent =
ng.core.Component({
selector: 'my-app',
inputs : ['hero'],
directives: [HeroDetailComponent],
template: `<h1>{{title}}</h1>My Heroes<h2></h2>
<ul class="heroes">
<li *ngFor="let hero of heroes"
[class.selected]="hero === selectedHero"
(click)="onSelect(hero)">
<span class="badge">{{hero.id}}</span> {{hero.name}}
</li>
</ul>
<my-hero-detail [hero]="selectedHero"></my-hero-detail>
`
})
.Class({
constructor: function() {
this.title = 'Tour of Heroes'
this.heroes = HEROES
this.selectedHero = null
},
onSelect(hero) { this.selectedHero = hero; }
});
})(window.app || (window.app = {}));enter code here
In Javascript, all variables are bound to the app which is in turn bound to the window.
You should define your HeroDetailComponent the same way AppComponent is defined.
(function (app) {
app.HeroDetailComponent = ng.core.Component({
selector: 'hero-detail',
inputs: ['hero'], // <-- this is necessary to receive the "selectedHero"
template: ` <!-- ... --> `
}).Class({
constructor: function () {
}
});
})(window.app || (window.app = {}));
Make sure to include the file in your index.html
<!-- 2. Load our 'modules' -->
<script src='app/hero.js'></script>
<script src='app/hero-detail.component.js'></script>
<script src='app/app.component.js'></script>
<script src='app/main.js'></script>
In your AppComponent, add the newly created HeroDetailComponent like so
app.AppComponent = ng.core.Component({
directives: [app.HeroDetailComponent], <-- // note the dependence on the `app` object
// ... and other things
}).Class({ /* Class Declaration */ });
