Angular 7隐藏打字稿中的bootstrap模态

Question

我想在我的typescript组件中的一个函数中调用（click）=“MDBootstrap Modal的基本Modal.hide（）”方法。我不知道如何从组件访问此方法。

<button type="button" mdbBtn color="primary" class="relative waves-light" (click)="basicModal.show()" mdbWavesEffect>Launch demo modal</button>

<div mdbModal #basicModal="mdbModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myBasicModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close pull-right" aria-label="Close" (click)="basicModal.hide()">
          <span aria-hidden="true">×</span>
        </button>
        <h4 class="modal-title w-100" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" mdbBtn color="secondary" class="waves-light" aria-label="Close" (click)="basicModal.hide()" mdbWavesEffect>Close</button>
        <button type="button" mdbBtn color="primary" class="relative waves-light" mdbWavesEffect>Save changes</button>
      </div>
    </div>
  </div>
</div>

您必须使用Angular的@ViewChild装饰器来定位mdbModal directrive，然后使用ModalDirective类中的hide（）方法。

请看下面的代码，解释了一切：

html的：

<button type="button" mdbBtn color="primary" class="relative waves-light" (click)="basicModal.show()" mdbWavesEffect>Launch demo modal</button>

<div #modal mdbModal #basicModal="mdbModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myBasicModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close pull-right" aria-label="Close" (click)="basicModal.hide()">
          <span aria-hidden="true">×</span>
        </button>
        <h4 class="modal-title w-100" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <div class="md-form">
          <input type="text" class="form-control" id="input1" mdbInput>
          <label for="input1">Modal input</label>
        </div>
      </div>
      <div class="modal-footer">
        <button mdbBtn color="primary" mdbWavesEffect (click)="hideModal()">Hide modal</button>
      </div>
    </div>
  </div>
</div>

.TS：

 @ViewChild(ModalDirective) modal: ModalDirective;

  hideModal() {
    this.modal.hide();
  }
