动态更改Angular 5 ng引导模式对话框的模板

动态更改Angular 5 ng引导模式对话框的模板,angular,typescript,ng-bootstrap,Angular,Typescript,Ng Bootstrap,我正在处理一个模式对话框,我需要能够动态地更改templateURL以进行动态更改。显示的是默认模板。我只是想知道如何实现这一点,因为传入templateURL名称和位置时会调用它。下面是我的组件代码: import { ModalService } from './../../services/modal.service'; import {Component, Input} from '@angular/core'; import {NgbModal, NgbActiveModal} fr

我正在处理一个模式对话框,我需要能够动态地更改templateURL以进行动态更改。显示的是默认模板。我只是想知道如何实现这一点,因为传入templateURL名称和位置时会调用它。下面是我的组件代码:

import { ModalService } from './../../services/modal.service';
import {Component, Input} from '@angular/core';

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

@Component({
  selector: 'app-ngbd-modal-content',
  templateUrl: '../../templates/modal.tp1.html'
})

export class ModalOptionsComponent {
  @Input() name;

  constructor(public activeModal: NgbActiveModal, modelService: ModalService) {}
}

export class  NgbdModalComponent {
  constructor(private ngbModal: NgbModal) {}
}
理想情况下,我希望从下面的服务类中打开它,而不是从组件中打开它,但我不确定如何做到这一点。我已经做了相当多的研究,但我没有找到多少关于如何实现这一点

Modal.service.ts:

import { ModalOptionsComponent } from './../pages/modal-options/modal-options.component';
import { Injectable } from '@angular/core';
import {NgbModal, NgbActiveModal} from '@ng-bootstrap/ng-bootstrap';

@Injectable()
export class ModalService {

  constructor(private ngbModal: NgbModal, private modalComp: ModalOptionsComponent) { }

  modalService(modal: any) {
    const modalDefaults = {
      templateUrl: '../templates/modal.tp1.html'
    };
    const modalOptions = {
      hasClose: true,
      closeButtonText: 'CLose',
      actionButtonText: 'OK',
      headerText: 'Proceed?',
      bodyText: 'Perform this action?',
      okResult: {}
    };
  }

  showModal(customModalDefaults: any, cusomeModalOptions: any) {

  }


}

我需要做的一件事就是为此创建服务类。我对angular非常陌生,不知道如何实现这一点。

首先:NgbModal,NgbActiveModal来自包'@ng bootstrap/ng bootstrap'

我认为您不需要创建单独的服务,因为“动态模板”功能可以通过软件包本身提供的内容来实现。让我们看看如何:

请参考下图(我想这就是场景)。在您放置“默认模式”的主组件中,在我的示例中是-detail(文件夹),模式(默认模式)是从该组件(-detail.component)触发的

假设您正在通过单击按钮在*-detail.component中编辑事件。此单击将触发“默认模式”弹出窗口。让我们在代码中看到这一点

*-.detail.component.html
编辑

*-detail.component.ts

editEvents(events) {
const activeModal = this.modalService.open(DefaultModal, { size: 'lg' });
activeModal.componentInstance.modalHeader = 'Edit Event';
activeModal.componentInstance.eventdata = events;  }
现在,模态组件: modal.component.html

<p>{{modalHeader}}</p>
<p> {{eventdata }} </p>
{{modalHeader}

{{eventdata}}

请注意,您需要对文件进行必要的导入。 在组件模块导入中,NgbModalModule还添加到导入阵列。 在component.ts文件中:NgbModal并从“./default-modal/default-modal.component”导入{DefaultModal}


因为我找不到改变templateUrl的能力,我不得不为我需要的每种类型的对话框创建一个组件。这样做的缺点是它不再是动态的,但它符合我的需要。基本上,您可以使用服务生成所需的组件类型。不幸的是,使用动态组件加载并不是一个真正可行的解决方案,因为这样做很复杂。下面是我所做的一个例子

默认模式对话框的组件代码:

import {Component, Input} from '@angular/core';

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

@Component({
  selector: 'app-ngbd-modal-content',
  template: `
<div class="modal-header">
<h3 class="font-32" style="padding-bottom: 0px">{{headerText}}</h3>
</div>
<div class="modal-body">
<p>{{bodyText}}</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-outline-dark" (click)="activeModal.close('Close click')">Close</button>
</div>
  `,
  styleUrls: ['./default-modal-dialog.component.scss']
})
export class DefaultModalDialogComponent {
  @Input() bodyText;
  @Input() headerText;

  constructor(public activeModal: NgbActiveModal) {}

}

我在我的应用程序中这样做,而不是创建不同的templateURL,我只是使用*ngIf来分隔要显示的内容。您还可以在组件中使用变量,这将有条件地更改任何文本。祝你好运@不幸的是,我已经创建了.html,我必须使用它。我还可以将模板放在精简的html组件中,并有条件地在通用模式模板中调用它们。你能这样做吗?或者你是在坚持这样做吗?将每个模板构建为自己的组件,然后根据需要动态加载它们@JC福特我同意
