Angular2 TypeError:linkParams.forEach不是函数

Question

我试图从click事件的函数显式导航到路由

<a (click)="loadContact()">Contact</a>

AppComponent class是这样定义的

export class AppComponent{

    constructor(private _router:Router){}

    public loadContact = function(){
        ...
        ...
        this._router.navigate('[Contact]');
    }
}

但是我收到了这个错误

TypeError: linkParams.forEach is not a function

我如何解决它？

编辑:

这是RouteConfig

@RouteConfig([
    { path: '/contact', name: 'Contact', component: ContactsComponent },
    { path: '/notes', name: 'Notes', component: NotesComponent }
])

Answer 1

TypeError: linkParams.forEach is not a function

错误原因: When a redirect, or router link is setup incorrectly and an array is not provided, an error is thrown

报告也提供更好的错误处理:https://github.com/angular/angular/issues/7952

你的代码

这里 :

this._router.navigate('[Contact]');

是一个字符串.它应该是 :

this._router.navigate(['Contact'] /* some array */);
