如何删除在使用angular 2动画时自动添加的ng-tns类

.ng-tns {
  all: initial !important;
}

import { AnimationEvent } from '@angular/animations';

@Component({
  // 组件配置
})
export class MyComponent implements OnInit {
  onAnimationDone(event: AnimationEvent) {
    if (event.toState === 'void') {
      const element = event.element as HTMLElement;
      element.classList.remove('ng-tns');
    }
  }
}

import { Renderer2 } from '@angular/core';

@Component({
  // 组件配置
})
export class MyComponent {
  constructor(private renderer: Renderer2) {}

  removeNgTnsClass() {
    const element = document.getElementById('myElement');
    this.renderer.removeClass(element, 'ng-tns');
  }
}
