Dplayer 实现视频（URL）切换

首先呢，先声明一个，很简单的，然后调用sw()就可以了

<div class="card" style="width:100%;height:60%;margin-top:7.5%;">
		<div id="dplayer" class="background2"></div>
		<script>
			const dp = new DPlayer({
			container: document.getElementById('dplayer'),
			screenshot: true,
			video: {
				url: 'http://static.smartisanos.cn/common/video/t1-ui.mp4',
				pic: 'http://static.smartisanos.cn/pr/img/video/video_03_cc87ce5bdb.jpg',
				thumbnails: 'https://moeplayer.b0.upaiyun.com/dplayer/hikarunara_thumbnails.jpg'
			}
		})function sw(){
			dp.switchVideo({
    url: 'video/背景.mp4',
    pic: 'http://static.smartisanos.cn/pr/img/video/video_03_cc87ce5bdb.jpg',
    thumbnails: 'https://moeplayer.b0.upaiyun.com/dplayer/hikarunara_thumbnails.jpg'
			})
		}
		</script>
