单击按钮时 ngx-bootstrap-accordion hide/show

Question

我有动画ngx-bootstrap-accordion 但如果我点击得足够快，标签将不符合 accordion 的状态。我希望标签说 hide 如果有东西要隐藏，而不是当内容可见时。

自从您在模板上改变可见属性后，对象的引用没有发生变化，因此不会触发手风琴组件变化检测。

试试这个：

component.html

    <button *ngIf="subsection.visible"  (click)="toggle(i)">
           Open panel
     </button>

component.ts

toggle(index){
    this.sections[index] = {
      ... this.sections[index],visible: ! this.sections[index].visible
 }
}
