Angular 7 / ngx-bootstrap 4.0.1

Dependencies

"bootstrap": "3.3.7",
"bootstrap-colorpicker": "2.5.1",
"bootstrap-duallistbox": "3.0.6",
"bootstrap-markdown": "2.10.0",
"bootstrap-progressbar": "0.9.0",
"bootstrap-slider": "9.8.0",
"bootstrap-tagsinput": "0.7.1",
"bootstrap-timepicker": "0.5.2",

在Angular 7中,我有一个组件。它只是一个按钮,当您单击它时,它显示一个模式。

如果我从div之类的元素中调用它,它将起作用。

但是当我从下拉菜单中调用它时,模态将不会出现。

这是我的代码:

正常通话:模式可见:

<shared-article-copy (ArticleEM)="addArticle($event, 'articleCopie')" [agentId]="this.samplesBill.recipient.agent_Id"
    *ngIf="this.samplesBill && this.samplesBill.recipient"></shared-article-copy>

从下拉菜单中调用:模式不可见:

<div class="btn-group">
    <button type="button" class="btn btn-primary">Apple</button>
    <button type="button" class="btn btn-primary">Test 1</button>
    <div class="btn-group">
        <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown">
        Test2 <span class="caret"></span></button>
        <ul class="dropdown-menu" role="menu">
        <li> <shared-article-copy (ArticleEM)="addArticle($event, 'articleCopie')" [agentId]="this.samplesBill.recipient.agent_Id"
            *ngIf="this.samplesBill && this.samplesBill.recipient"></shared-article-copy></li>
        </ul>
    </div>
</div>

我认为,组件的视图绑定到li元素而不是主体。

这是组件视图shared-article-copy的代码的一部分:

<button type="button" class="btn btn-labeled btn-primary" (click)="loadModalArticleImport()" ng-dblclick="return false;">
    <span class="btn-label">
        <i class="fa fa-plus"></i>
    </span>{{ textTitle }}
</button>

<div bsModal #calculatorModal="bs-modal"  class="modal fade" tabindex="0" role="dialog" aria-labelledby="myLargeModalLabel"
     aria-hidden="true" style="background-color: white" [hidden]="!articleCalculator" (onHidden)="closeCalculatorModal()"
>
    <div class="modal-dialog modal-lg" style="background-color: white">
        <div class="modal-content">
            <div class="modal-header" *ngIf="articleCalculator">
               Modal Header 
            </div>
            <div class="modal-body">
               modal body !
            </div>
        </div>
    </div>
</div>

我无法复制该组件的所有代码,因为它们不相关。

这是的一部分:

export class SharedArticleCopyComponent implements OnInit {

  @Input() buttonClass: string;
  @Input() agent: Agent; // pour avoir un client par défaut
  @Input() agentId: string; // Quand on a pas lagent mais que son ID people
  @Input() textTitle: string = 'Copier un article existant';
  @Input() calculatorTitle: string = 'Détails de l\'article: ';
  @Input() AgentReadonly: boolean = false;

  @Output() public ArticleEM: EventEmitter<Article> = new EventEmitter<Article>();

  @ViewChild('copyArticleModal') public lgModal: ModalDirective;
  @ViewChild('calculatorModal') public lgCalculatorModal;

  constructor(private httpClient: HttpClient, private articlesService: ArticlesService, public agentsClientsService: AgentsClientsService, public peopleService: PeopleService,
    private sessionService: SessionService, private _route: ActivatedRoute,
    private notificationLGIService: NotificationLGIService, private datePipe: DatePipe, private domService: DomService) {

  }

即使从下拉菜单中调用组件,如何使模态可见?

1 个答案:

答案 0 :(得分:0)

您看不到该模式,因为它是隐藏的下拉菜单的子菜单。

将组件放入下拉列表中时,您将得到以下DOM结构。

drop-down menu(position:absolute) > shared-article-copy > modal(position:fixed)

单击按钮以打开模态时,模态会打开,但下拉菜单也会关闭,并且显示设置为none

drop-down menu(display:none) > shared-article-copy > modal(position:fixed)

因此您看不到下拉列表及其任何子项(包括模态)。

解决方案:

  1. 不要将模式放在下拉列表中(推荐)。
  2. 为包含模式(demo on stackblitz)的下拉列表修补Bootstrap CSS。

包含模态的引导程序下拉列表的CSS:

.dropdown-menu.contains-modal {
    position: unset;
    display: inline-block;
    height: 0;
    width: 0;
    min-width: unset;
    overflow: hidden;
    border: 0;
    padding: 0;
}
.open>.dropdown-menu.contains-modal {
    position: absolute;
    height: unset;
    width: unset;
    min-width: 160px;
    padding: 5px 0;
    border: 1px solid rgba(0,0,0,.15);
    overflow: unset;
}

并使用

<ul class="dropdown-menu contains-modal">...

代替

<ul class="dropdown-menu">...
