我正在尝试添加 HTML 音频播放器。我在那里应用了一个代码播放暂停工作。我需要在这里添加时间线功能。但不知道该怎么做。这里还有另一个问题,我不知道如何在同一个按钮中应用播放暂停。请帮我。下面是我的代码。 sample
#audioplayer{
width: 480px;
height: 60px;
margin: 50px auto auto auto;
border: solid;
}
#pButton{
height:60px;
width: 60px;
border: none;
background-size: 50% 50%;
background-repeat: no-repeat;
background-position: center;
float:left;
outline:none;
}
.play, .play:hover, .pause:focus{background: url('https://img.pranavc.in/20') ;}
.pause, .pause:hover, .play:focus{background: url('https://img.pranavc.in/30') ;}
#timeline{
width: 400px;
height: 20px;
margin-top: 20px;
float: left;
border-radius: 15px;
background: rgba(0,0,0,.3);
}
#playhead{
width: 18px;
height: 18px;
border-radius: 50%;
margin-top: 1px;
background: rgba(0, 0, 0,1);
}
<audio id="player" src="https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3"></audio>
<div id="audioplayer">
<button id="pButton" class="play" onclick="document.getElementById('player').play()"></button>
<button id="pButton" class="pause" onclick="document.getElementById('player').pause()"></button>
<div id="timeline">
<div id="playhead"></div>
</div>
</div>
最佳答案
我使用 javascript,并更改了 dom 和 css。 您需要了解音频事件和属性。
var audio = document.getElementById("player");
var btn = document.getElementById("pButton");
btn.addEventListener("click", function(){
if (audio.paused) {
audio.play();
btn.classList.remove("pause");
btn.classList.add("play");
} else {
audio.pause();
btn.classList.remove("play");
btn.classList.add("pause");
}
});
var playhead = document.getElementById("playhead"); audio.addEventListener("timeupdate", function(){ var duration = this.duration; var currentTime = this.currentTime; var percentage = (currentTime / duration) * 100; playhead.style.left = percentage * 4 + 'px'; });
#audioplayer{
position: relative;
width: 480px;
height: 60px;
margin: 50px auto auto auto;
border: solid;
}
#pButton{
height:60px;
width: 60px;
border: none;
float:left;
outline:none;
}
#pButton.pause {
background: url('https://img.pranavc.in/20') no-repeat;
background-size: 56px;
background-position: center;
}
#pButton.play {
background: url('https://img.pranavc.in/30') no-repeat;
background-size: 56px;
background-position: center;
}
#timeline{
width: 400px;
height: 20px;
margin-top: 20px;
float: left;
border-radius: 15px;
background: rgba(0,0,0,.3);
position: relative;
}
#playhead{
width: 18px;
height: 18px;
border-radius: 50%;
margin-top: 1px;
background: rgba(0, 0, 0,1);
position: absolute;
left: 0px;
}
<audio id="player" src="https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3"></audio>
<div id="audioplayer">
<button id="pButton" class="pause"></button>
<div id="timeline">
<div id="playhead"></div>
</div>
</div>
