隐藏的上传表单不会在Angular中注册更改事件

<input type="file" #hiddenInput style="display: none;">

import { Component, ViewChild, ElementRef, AfterViewInit } from '@angular/core';

@Component({
  selector: 'app-upload',
  templateUrl: './upload.component.html',
  styleUrls: ['./upload.component.css']
})
export class UploadComponent implements AfterViewInit {
  @ViewChild('hiddenInput') hiddenInput: ElementRef;

  ngAfterViewInit() {
    this.hiddenInput.nativeElement.addEventListener('change', this.handleFileChange.bind(this));
  }

  handleFileChange(event: Event) {
    // 处理文件变化事件
    const files = (event.target as HTMLInputElement).files;
    // ...
  }
}
