这是我的第一个角度2应用程序，不知道为什么bootstrap类不应用或glyphicons丢失？有人可以解释如何在角度2中使用引导类？bootstrap类不适用于角度2组件
这是我app.component.ts
import {Component} from 'angular2/core';
import {LikeComponent} from './like.component'
@Component({
selector: 'my-app',
template: `
<like [totalLikes]="tweet.totalLikes" [iLike]="tweet.iLike"></like>
`,
directives: [LikeComponent]
})
export class AppComponent {
tweet = {
totalLikes: 10,
iLike: false
}
}而且like.component.ts：
import {Component, Input} from 'angular2/core';
@Component({
selector: 'like',
template: `
<i
class="glyphicon glyphicon-heart"
[class.highlighted]="iLike"
(click)="onClick()">
</i>
<span>{{ totalLikes }}</span>
`,
styles: [`
.glyphicon-heart {
color: #ccc;
cursor: pointer;
}
.highlighted {
color: deeppink;
}
`]
})
export class LikeComponent {
@Input() totalLikes = 0;
@Input() iLike = false;
onClick(){
this.iLike = !this.iLike;
this.totalLikes += this.iLike ? 1 : -1;
}
}
