Question

我有这个文件

bar-chart-card.component.ts

import { NgModule } from '@angular/core';
import { Component } from '@angular/core';
import { NbMenuService, NbSidebarService } from '@nebular/theme';
import { NbDialogService } from '@nebular/theme';
import { filter, map } from 'rxjs/operators';
import { DialogNamePromptComponent } from './detail-view.component';


@Component({
  selector: 'ngx-bar-chart-card',
  templateUrl: './bar-chart-card.component.html',
  styleUrls: ['./bar-chart-card.component.scss']
})
export class BarChartCardComponent {

  flipped = false;
  cardSettingCtxMenu = [{ title: 'Profile' }, { title: 'Log out' }];

  constructor(
    private dialogService: NbDialogService,
    private menuService: NbMenuService) {
  }  


  ngOnInit() {
    console.log("asasas");
    this.menuService.onItemClick()
      .pipe(
        filter(({ tag }) => tag === 'my-context-menu'),
        map(({ item: { title } }) => title),
      )
       .subscribe(title => this.open3());
  }

  toggleView() {
    this.flipped = !this.flipped;
  }

  open3() {
    console.log("================");
    this.dialogService.open(DialogNamePromptComponent);
  }

}

detail-view.component.ts

import { Component } from '@angular/core';
import { NbDialogRef } from '@nebular/theme';

@Component({
  selector: 'ngx-detail-view',
  templateUrl: './detail-view.component.html'
})
export class DialogNamePromptComponent {

  constructor(protected ref: NbDialogRef<DialogNamePromptComponent>) {}

  cancel() {
    this.ref.close();
  }

  submit(name) {
    this.ref.close(name);
  }
}

e-commerce.module.ts

    import { BarChartCardComponent } from './bar-chart-card/bar-chart-card.component';
    import { DialogNamePromptComponent } from './bar-chart-card/detail-view.component';

    @NgModule({
      imports: [
        ThemeModule,
        ChartModule,
        NgxEchartsModule,
        NgxChartsModule,
        LeafletModule,
      ],
      declarations: [
    DialogNamePromptComponent,
    BarChartCardComponent
  ],
  providers: [
    CountryOrdersMapService,
  ],
  entryComponents: [BarChartCardComponent,DialogNamePromptComponent]
})
export class ECommerceModule { }

当我调用方法open3时，出现此错误：

未找到DialogNamePromptComponent的组件工厂。您将其添加到@NgModule.entryComponents了吗？

Answer 1

通常，您需要在模块定义的entryComponents数组中添加将动态构建的所有组件。

<head>
  <style>
    /* style your table here */
  </style>
</head>
<table>
<? for (var row in data) { ?>
  <tr>
<?   for (var col in data[row]) { ?>
  <td> <?= data[row][col] ?> </td>
<?   } ?>
  </tr>
<? } ?>
</table>

这在Nebular的文档中没有指定，但是我认为他们使用的是Angular的ComponentFactoryResolver，如果没有在其他地方加载该组件，则需要此。

但是，我注意到您为BarChartCardComponent类的组件装饰器错误地添加了NgModule装饰器，这是我以前从未见过的。据我所知，一个类不能同时是一个组件和一个模块。因此，删除该NgModule装饰器。

将 DialogNamePromptComponent 添加到父模块'entryComponents

@NgModule({
  declarations: [DialogNamePromptComponent],
  entryComponents: [
  DialogNamePromptComponent
],
})

找不到DialogNamePromptComponent的组件工厂。您是否将其添加到@ NgModule.entryComponents？
