angular 7 中未定义路由器中的数据

Question

我有如下路线：

{ 路径：'contact-us'，组件：ContactUsComponent，数据：{isPrivate: false}},

当我尝试在 ContactUsComponent.ts 的 ngOnInit() 上获取上述 isPrivate 值时，它给出未定义的：

constructor(private route: ActivatedRoute) {}
..
ngOnInit() {
 this._private = this.route.snapshot.data['isPrivate'];
}

Answer 1

看看这个

constructor(router:Router, route: ActivatedRoute) {
    router.events
      .filter(e => e instanceof NavigationEnd)
      .forEach(e => {
        this.title = route.root.firstChild.snapshot.data['PageName'];
    });
}

Answer 2

尝试在构造函数中正确获取属性：

constructor(private route: ActivatedRoute) {
    this._private = this.route.snapshot.data['isPrivate'];
}

Answer 3

也许可以试试：-

constructor(private route: ActivatedRoute) {}
OnInit() {
  this.route.data.subscribe(private => this._private = private);
}
