Angular6 Router navigate to multiple child routes that share the same component

由 孤街醉人 提交于 2019-12-25 01:49:58
问题 I have multiple child components that share the same component which works fine, however, I cannot route between the pages as it appears Angular suspects the component is already loaded. Is it possible to reload the component when attempting to route to these child routes? const ServicesRouting: ModuleWithProviders = RouterModule.forChild([ { path: '', component: StructureComponent, canActivate: [AuthGuard], children: [ { path: 'services', canActivate: [AuthGuard], component:
