<template #warningModal let-c="close" let-d="dismiss">
  <div class="modal-header">
    <button type="button" class="close" aria-label="Close" (click)="d('Cross click')">
      <span aria-hidden="true">&times;</span>
    </button>
    <h4 class="modal-title">Warning</h4>
  </div>
  <div class="modal-body">
      The numbers you have entered result in negative expenses.  We will treat this as $0.00.  Do you want to continue?
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-secondary" (click)="c('Close click')">No</button>
    <button type="button" class="btn btn-secondary" (click)="submit()">Yes</button>
  </div>
</template>

每当我单击是,我希望它调用一个函数并关闭它自己.
在我的控制器中,我有@ViewChild(‘warningModal’)警告;并且在submit()中,我有this.warning.close();,但是我得到这个.每当我点击是时,warning.close都不是函数.

我如何让它以我想要的方式工作？
