如何從ActivatedRoute（Angular2）獲得出口PARAMS

Question

我的路線定義爲：

path: 'geooperations', 
    component: GeoMetricsComponent, 
    children: [ 
     { path: ':idgeooperationmetrictype', component: DetailGeoMetricTypeComponent, outlet: 'geo' }, 
     { path: ':idgeooperationmetrictype/edit', component: DetailGeoMetricTypeComponent, outlet: 'geo' }, 
     { path: '/new', component: DetailGeoMetricTypeComponent, outlet: 'geo' } 
    ] 

例子： 網址：geooperations /（GEO：c56da64c-0ef5-4894-83ee-04381​​8b44e14）

outlet : 'geo' 
idgeooperationmetrictype: 'c56da64c-0ef5-4894-83ee-043818b44e14' 

如何從ActivatedRoute獲得'idgeooperationmetrictype'？

Answer 1

使用snapshot.params解決問題：

this.activatedRoute.snapshot.params.subscribe(params => {   
    console.log(params['idgeooperationmetrictype']); 
}); 

Answer 2

您需要在PARAMS線訂閱它的組成部分「DetailGeoMetricTypeComponent」

ngOnInit() { 
    this.sub = this.route.params.subscribe(params => { 
     this.id = params['idgeooperationmetrictype']; 
    }); 
    } 

或者設置斷點內與開發工具，以看清按鍵。
