或者,您可以通过单击按钮添加JavaScript来暂停/播放视频:
<script>
// Get the video
var video = document.getElementById("myVideo");
// Get the button
var btn = document.getElementById("myBtn");
// Pause and play the video, and change the button text
function myFunction() {
if (video.paused) {
video.play();
btn.innerHTML = "Pause";
} else {
video.pause();
btn.innerHTML = "Play";
}
}
</script>
//获取视频
var video=document.getElementById(“myVideo”);
//扣上按钮
var btn=document.getElementById(“myBtn”);
//暂停并播放视频,然后更改按钮文本
函数myFunction(){
如果(视频暂停){
video.play();
btn.innerHTML=“暂停”;
}否则{
video.pause();
btn.innerHTML=“播放”;
}
}
因此,这不是一项免费的代码编写服务,请您自己尝试实现这一点,如果在此过程中出现任何问题,请尝试。我们很乐意提供帮助。您也可以在保存视频标签的div上使用
