[modal-dialog] 각도 2.0 및 모달 대화 상자

A와 사용할 수 NPM 패키지

각도 맞춤 모달

@Stephen Paul 계속 …

• 각도 2 및 부트 스트랩 CSS (애니메이션은 유지됨)
• 아니 JQuery
• bootstrap.js 없음
• 커스텀 모달 컨텐츠 지원
• 서로의 여러 모달을 지원합니다.
• 모듈화
• 모달이 열려있을 때 스크롤 비활성화
• 탐색하면 모달이 파괴됩니다.
• 게으른 콘텐츠 초기화 ngOnDestroy. 모달이 종료되면 가져 옵니다.
• 모달이 표시되면 부모 스크롤이 비활성화됩니다.

게으른 콘텐츠 초기화

왜?

어떤 경우에는 닫은 후에 상태를 유지하기 위해 모달을 원하지 않고 오히려 초기 상태로 복원 할 수 있습니다.

원래 모달 문제

내용을 뷰로 직접 전달하면 실제로 모달이 가져 오기 전에도 내용을 초기화합니다. 모달에는 *ngIf래퍼를 사용하더라도 이러한 내용을 죽일 수있는 방법이 없습니다 .

해결책

ng-template. ng-template그렇게 명령하기 전까지는 렌더링되지 않습니다.

my-component.module.ts

imports: [
  ...
  ModalModule
]

my-component.ts

<button (click)="reuseModal.open()">Open</button>
<app-modal #reuseModal>
  <ng-template #header></ng-template>
  <ng-template #body>
    <app-my-body-component>
      <!-- This component will be created only when modal is visible and will be destroyed when it's not. -->
    </app-my-body-content>
    <ng-template #footer></ng-template>
</app-modal>

modal.component.ts

export class ModalComponent ... {
  @ContentChild('header') header: TemplateRef<any>;

인터넷에 대한 훌륭한 공식 및 커뮤니티 문서가 없으면 불가능했을 것입니다. 그것은 당신의 일부가 너무 더 나은 방법을 이해하는 데 도움이 될 ng-template, *ngTemplateOutlet및 @ContentChild작동합니다.
