使用当前音频创建播放/暂停功能 [英] Creating play/pause functions with current audio javascript

问题描述

我有一个扩展程序用于我正在使用的chrome，我有一个HTML弹出窗口，其中包含播放音频的按钮。我不认为我的方法是最优雅的，我无法探索缩小这种方式的方法。我知道这是非常低效的。我希望能够分辨HTML页面上的哪个按钮被点击，然后使用该ID播放具有相同ID的音频文件。我现在的方式是使用JavaScript中的EventListener来使用多个函数来停止或播放。有没有办法把所有这一切通过JavaScript或jQuery的一个函数来解决这个混乱？ 由于我在Chrome浏览器扩展中执行此操作，因此无法在HTML文档中使用Javascript。

目前，我拥有这样的HTML; p>

 < script type =text / javascriptsrc =js / audio.js>< / script> 
 
< a href =＃class =myButtonid =stopbutton>停止音频< / a> 
< a href =＃class =myButtonid =aud1>音频1< / a> 
< a href =＃class =myButtonid =aud2> Audio 2< / a> 
< a href =＃class =myButtonid =aud3>音频3< / a> 
  

我的JS文件像这样为我的音频文件创建变量。

  var aud1 = new Audio（）; 
 var aud2 = new Audio（）; 
 var aud3 = new Audio（）; 
  

与此功能一起使用相应名称选择按钮时开始播放。

 函数aud1play（）{
 aud1.src =mp3 / aud1.mp3; 
 aud1.play（）; 
} 
 document.getElementById（'aud1'）。addEventListener（'click'，aud1play）; 
 
 //获得趋势
  

要停止我的音频，我有以下函数：

 函数audstop（）{
 aud1.pause; 
 aud2.pause; 
 aud3.pause; 
 document.getElementById（'stopbutton'）。addEventListener（'click'，audstop）; 
  

解决方案

var audios = Array.prototype.map.call（document.getElementsByClassName（myButton），function（el）{
var audio = new Audio（）;
audio.preload =none; // = >未预加载
audio.src =mp3 /+ el.id +。mp3;
el.onclick = audio.play.bind（音频）;
返回音频;
}）;


只需遍历按钮，使用正确的src为它创建一个音频元素，然后绑定onclick聆听其播放功能。然后映射音频元素。

  document.getElementById（'stopbutton'）。addEventListener（'click'，function（）{
 audios.forEach（audio => audio.pause（））; 
}）; 
  

要停止，只需遍历音频元素并在每个元素上调用stop函数... p>

I have an extension for chrome I am working on, I have an HTML popup that has buttons that play audio. I don't think my approach is the most elegant and I am having trouble exploring ways to shrink this down. I know this is very inefficient. I want to be able to tell which button was clicked on the HTML page, then using that ID play the audio file with that same ID. The way I have it now is using the EventListener in javascript to use multiple functions to stop or play. Is there a way to put all of this in one function through javascript or jquery to fix this chaos? Since I am doing this on a chrome extension I cannot use Javascript in the HTML document.

Currently I have my HTML like this;

    <script type="text/javascript" src="js/audio.js"></script>

    <a href="#" class="myButton" id="stopbutton">Stop Audio</a> 
    <a href="#" class="myButton" id="aud1">Audio 1</a>
    <a href="#" class="myButton" id="aud2">Audio 2</a>
    <a href="#" class="myButton" id="aud3">Audio 3</a>

My JS file like this to create the variables for my audio files.

    var aud1 = new Audio();
    var aud2 = new Audio();
    var aud3 = new Audio();

Along with this function to start playback when a button is selected with the coresponding name.

    function aud1play() {
        aud1.src = "mp3/aud1.mp3";
        aud1.play();
    }
    document.getElementById('aud1').addEventListener('click', aud1play);

    //you get the trend

To stop my audio I have the following function:

    function audstop() {
        aud1.pause;
        aud2.pause;
        aud3.pause;
    document.getElementById('stopbutton').addEventListener('click', audstop);

解决方案

var audios= Array.prototype.map.call(document.getElementsByClassName("myButton"),function(el){
    var audio=new Audio();
    audio.preload="none";//=> not preloaded
    audio.src="mp3/"+el.id+".mp3";
    el.onclick=audio.play.bind(audio);
    return audio;
});

Simply iterate over your buttons, create an audio element with the right src for it, and bind the onclick listener to its play function. Then map the audio elements.

document.getElementById('stopbutton').addEventListener('click', function(){
    audios.forEach(audio=>audio.pause());
});

To stop, simply iterate over the audio elements and call the stop function on each...
