Question

我正在尝试在导航菜单中获取Angular路径查询。每当我尝试

this.route.paramMap.subscribe(params =>
            this.Name = params.get('name')
        );

我得到未定义或null。

完整代码

constructor(private route: ActivatedRoute) {}

ngOnInit() {
    var name;

   this.route.paramMap.subscribe(params =>
        name = params.get('name')
    );

    alert(name);
}

Answer 1

this.route.paramMap
      .switchMap((params: ParamMap) => {
          return Observable.of(params);
      }).subscribe(() => {
          name = params.get('name')
});

试试这个！

Answer 2

你可以尝试

name=""
this.route.paramMap.subscribe(param => {
    this.name = param.get('name');
});

Answer 3

 public constructor(private route:ActivatedRoute, private router:Router) {
      console.log(route.snapshot.data['name']);
  }
