未捕获的错误：无法解析“ComponentName”的所有参数：（[object Object]，？）

Question

我不知道为什么我收到错误

compiler.js:2175 Uncaught Error: Can't resolve all parameters for ClauseListComponent: ([object Object], ?).

我正在尝试使用 ngbModal，这是我到目前为止所做的。

子句.module.ts

import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [ModuleListComponent,ClauseListComponent,ModifyClauseComponent],
  imports: [
    NgbModule

条款清单.html

<ng-template #content let-modal >
    <div class="modal-header">
        <h4 class="h4Header" id="modal-basic-title">Title</h4>
        <button type="button" class="close" aria-label="Close" (click)="modal.dismiss('Cross click')">
        <span aria-hidden="true">×</span>
        </button>
    </div>
    <div class="modal-body">
                        CheckMate!     
    </div>
    <div class="modal-footer">
        <button mat-flat-button class="text-btn" (click)="modal.close('Save click')">ENROLL NOW</button> 
        <button mat-flat-button class="text-btn" (click)="modal.close('Save click')">Later</button> 
    </div>
</ng-template>
<button mat-flat-button class="primary-btn marR16" (click)="open(content)">Modal dialog</button>

和.ts 文件

import {NgbModal} from '@ng-bootstrap/ng-bootstrap';

constructor(private service : OfferClauseService,private modalService: NgbModal) { }
 open(content) {
    this.modalService.open(content,{windowClass:'custom_modal'})
  }

配置文件

    "lib": [
      "es2018",
      "dom"
    ]

指望你们！ 请询问是否需要更多说明。

您需要将它导入到您的 NgModule 中，而不是将其注入到您的组件中。

import { ModalModule } from 'ngb-modal';

@NgModule({
  imports: [
    ...
    ModalModule,
  ],

从构造函数中移除private modalService: NgbModal ：

constructor(private service : OfferClauseService,private modalService: NgbModal) { }

而是添加ModalManager ：

export class YourComponent {
    @ViewChild('myModal') myModal;
    private modalRef;
    constructor(private modalService: ModalManager){}

    openModal(){
        this.modalRef = this.modalService.open(this.myModal, {
        ...
        })
    };
    ...

    closeModal(){
        this.modalService.close(this.modalRef);
        //or this.modalRef.close();
    }
}

您需要将对话框组件添加到模块中的entryComponents中。

@NgModule({
  declarations: [
    AppComponent, ModalComp
  ],
  imports: [
    ...
    ModalModule,
  ],
  providers: [],
  bootstrap: [AppComponent],
  entryComponents: [ModalComp]
})
