想要为全屏视频背景上的音频创建自定义静音/取消静音按钮答案

【问题标题】：Wanting to create a custom mute/unmute button for the audio on a full screen video background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
【发布时间】：2015-03-15 06:10:21
【问题描述】：

我目前有一个带有音频循环的全屏背景视频，我想制作一个自定义按钮，以便当访问者访问该网站时可以将音频静音/取消静音。

我已尝试使用此代码...

<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>

还有 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>

认为我可能找错树了吗？

任何帮助将非常感谢！

尝试 mutebtn.addEventListener("click",vidmute,false); ... 引用事件，而不是整个事件
@Offbeatmammal 感谢回复，但好像还是不行，真让我费解

【解决方案1】：

看起来需要三个小改动 1/ 仅在 click 周围引用而不是整个 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>
