当试图设置属性的类型时，我得到了错误Cannot find name 'Subscription'.我应该从哪个包裹导入？
import { Component, OnDestroy, OnInit } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
// I'm missing an import here. Just don't know which package to load from.
@Component({
moduleId: module.id,
selector: 'my-component',
templateUrl: 'my.component.html',
styleUrls: ['my.component.css']
})
export class MyComponent implements OnInit, OnDestroy {
private sub: any;
constructor(private route: ActivatedRoute,
private router: Router) {}
ngOnInit() {
this.sub = this.route.params.subscribe(params => {
let id = +params['id']; // (+) converts string 'id' to a number
});
}
ngOnDestroy() {
this.sub.unsubscribe();
}
}
Edit:提供了一个更详细的代码示例.
