我正在关注Angular2基础知识的Angular教程,试图将其转换为JavaScript,因为它目前仅适用于打字稿。
我目前有两个文件:app.component.js and hero-detail.component.js。位于app.component.js中,我有我的appComponent。由此,我想将组件加载为hero-detail.component.js作为指令。
我当前的代码看起来像这样,但是我不知道如何加载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
在JavaScript中,所有变量均绑定到 app
,后者依次绑定到window
。
您应该按照AppComponent
的方式定义HeroDetailComponent
。
(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 = {}));
确保将文件包括在您的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>
在您的AppComponent
中,添加新创建的HeroDetailComponent
,例如So
app.AppComponent = ng.core.Component({
directives: [app.HeroDetailComponent], <-- // note the dependence on the `app` object
// ... and other things
}).Class({ /* Class Declaration */ });
