Question

我想打开ManagePointsDialogComponent作为对话框。当我单击addPoints函数时，出现错误。

我的懒惰模块： users.management.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { SharedModule } from "../../shared/shared.module";
import { UsersListComponent } from './screens/users-list/users-list.component';
import { UsersManagementRoutingModule } from './users-management-routing.module';
import { UsersManagementComponent } from './components/users-management/users-management.component';
import { UserCreateComponent } from './screens/user-create/user-create.component';
import { UserDetailsComponent } from './screens/user-details/user-details.component';
import { ManagePointsDialogComponent } from './components/manage-points-dialog/manage-points-dialog.component';

@NgModule({
  declarations: [
    UsersListComponent,
    UserCreateComponent,
    UserDetailsComponent,
    UsersManagementComponent,
    ManagePointsDialogComponent,
  ],
  imports: [
    CommonModule,
    SharedModule,
    UsersManagementRoutingModule,
  ],
  entryComponents: [
    ManagePointsDialogComponent,
  ]
})
export class UsersManagementModule { }

此组件在惰性模块内部。从这个组件，我想打开对话框。 users-list.component.ts

constructor(private dialog: MatDialog) { }

private addPoints(id: string): void {
   this.dialog.open(ManagePointsDialogComponent, ManagePointsDialogComponent.buildConfiguration({addPoints: true, actionText: 'Add'}))
}

怎么了？

如果将其添加到应用程序模块中可能会起作用，因为有时entryComponents在延迟加载中无法很好地工作。希望对您有帮助
