想要为全屏视频背景上的音频创建自定义静音/取消静音按钮

Wanting to create a custom mute/unmute button for the audio on a full screen video background

本文关键字：创建 自定义 按钮 取消 音频 视频 背景      更新时间：2023-09-26

我目前有一个全屏背景视频，我循环播放音频，我想制作一个自定义按钮，以便在访问者访问该网站时可以将音频静音/取消静音。

我试过使用此代码...

<video id="bg" loop autoplay preload="auto" poster="../img/still.jpg">
   <source src="vid/vidbg2.mp4" type="video/mp4" />
   <source src="vid/vidbg.webm" type="video/webm" />
   <source src="vid/vidbg.ogv" type="video/ogg" />
   Your browser does not support this video
</video>
<div id="video_controls">
   <button id="mutebtn">mute</button>
</div>

和JavaScript

<script>
    var mutebtn;
    function intitializePlayer(){
    //set object references
    vid = document.getElementById("bg");
    mutebtn = document.getElementById("mutebtn");
    //add event listener
    mutebtn.addEventListener("click,vidmute,false");
  }
    function.vidmute(){
    if(vid.muted){
    vid.muted = false;
    mutebtn.innerHTML = "mute";
} else {
    vid.muted = true;
    mutebtn.innerHTML = "Unmute";
}
}
</script>

认为我可能吠错了树？

任何帮助将非常感谢！

在需要的地方看起来像三个小的变化1/只在click周围引号，而不是整个 addEventListener 参数2/调用初始化3/从function.vidmute中删除多余的句点 

<script>
var mutebtn;
intitializePlayer()  // **don't forget to call the initialize**
function intitializePlayer(){
    //set object references
    vid = document.getElementById("bg");
    mutebtn = document.getElementById("mutebtn");
    //add event listener
    mutebtn.addEventListener("click",vidmute,false);   // **quotes only around the event** 
}
function vidmute(){   // **there was an extra '.' between function and vidmute**
    if(vid.muted){
        vid.muted = false;
        mutebtn.innerHTML = "mute";
    } else {
        vid.muted = true;
        mutebtn.innerHTML = "Unmute";
    }
}
</script>
