将iframe视频加载为Angular中的图像

<iframe src="https://www.example.com/video" width="560" height="315"></iframe>

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

@Component({
  selector: 'app-video',
  templateUrl: './video.component.html',
  styleUrls: ['./video.component.css']
})
export class VideoComponent {
  @ViewChild('videoFrame') videoFrame: ElementRef;

  // 其他组件代码...
}

<iframe #videoFrame src="https://www.example.com/video" width="560" height="315"></iframe>

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

@Component({
  selector: 'app-video',
  templateUrl: './video.component.html',
  styleUrls: ['./video.component.css']
})
export class VideoComponent implements OnInit {
  @ViewChild('videoFrame') videoFrame: ElementRef;

  ngOnInit() {
    const iframeElement = this.videoFrame.nativeElement;
    const videoUrl = iframeElement.src;

    // 创建一个新的Image对象
    const image = new Image();

    // 设置图像的源为视频的URL
    image.src = videoUrl;

    // 将图像作为背景设置给某个元素
    // 例如，假设有一个<div id="videoImage"></div>元素
    const videoImageElement = document.getElementById('videoImage');
    videoImageElement.style.backgroundImage = `url(${image.src})`;
  }
}
