我一直在使用这个自定义音频播放器,我将它与一些教程放在一起并在互联网上解决,并且在过去的两个月里一直在使用它。
它在Chrome中100%工作,但在更新后,搜索栏碰巧停止工作。
这是我的问题吗?或者它对其他人有用吗?
HTML:
<div id="musicplayer">
<table>
<tr>
<audio id="audio" src="../audio/oby/weightless/Got To Be Free.mp3"></audio>
<td>
<button id="play" type="button" onclick="playPause()" ></button>
</td>
<td>
<div id="boxed" >
<a href="#" id="songName">Select a song from the playlist</a>
<p class="right" id="timeInfo">00:00</p>
<input type="range" step="any" id="seekbar"></input>
</div>
</td>
</tr>
</table>
</div>
JavaScript的:
<script>
var audio = document.getElementsByTagName('audio')[0],
div = document.getElementById('timeInfo');
function formatTime(s, m) {
s = Math.floor( s );
m = Math.floor( s / 60 );
m = m >= 10 ? m : '0' + m;
s = Math.floor( s % 60 );
s = s >= 10 ? s : '0' + s;
return m + ':' + s;
}
setInterval(function()
{
div.textContent = formatTime(audio.currentTime);
}, 100);
seekbar.value = 0;
var audio = document.getElementById("audio");
var seekbar = document.getElementById('seekbar');
function setupSeekbar() {
seekbar.min = audio.startTime;
seekbar.max = audio.startTime + audio.duration;
}
audio.ondurationchange = setupSeekbar;
function seekAudio() {
audio.currentTime = seekbar.value;
}
function updateUI() {
var lastBuffered = audio.buffered.end(audio.buffered.length-1);
seekbar.min = audio.startTime;
seekbar.max = lastBuffered;
seekbar.value = audio.currentTime;
}
seekbar.onchange = seekAudio;
audio.ontimeupdate = updateUI;
audio.addEventListener('durationchange', setupSeekbar);
audio.addEventListener('timeupdate', updateUI);
</script>
答案 0 :(得分:1)
重复代码:
audio.ondurationchange = setupSeekbar;
和
audio.addEventListener('durationchange', setupSeekbar);
尝试删除任何这些行。
如果在javascript中设置搜索栏值将会改变...你将不得不删除seekbar.onchange = seekAudio;
当用户随时点击时,您的搜索栏是否不会搜索?或者更新时间有问题。 (时间正在更新,但搜索栏没有)?
您不需要这些代码,也可能导致问题一...(搜索栏更新问题)
var lastBuffered = audio.buffered.end(audio.buffered.length-1);
seekbar.min = audio.startTime;
seekbar.max = lastBuffered;
编辑(offtopic):为了获得更好的性能,请删除代码
setInterval(function()
{
div.textContent = formatTime(audio.currentTime);
}, 100);
并将其附加到updateUI
div.textContent = formatTime(audio.currentTime);
