大家
我写了简单的音乐播放器,但我有一个问题。我使用ajax从文件php获取新的源代码并且工作正常,但我不知道如何播放新歌。简单的audio.play()不起作用。我尝试修复这是我的代码:
function timer(){
timeleft = $("span#timeleft");
slider = $("div#slider");
$(audio).bind('timeupdate', function(){
var rem = parseInt(audio.duration - audio.currentTime, 10),
pos = (audio.currentTime / audio.duration) * 315,
mins = Math.floor(rem/60, 10),
secs = rem - mins*60;
timeleft.text('- ' + mins + ':' + (secs > 9 ? secs : '0' + secs));
slider.css({width: pos + 'px'});
});
}
$(document).ready(function(){
audio = $("audio#audio-player-header").get(0);
$("div#controls").click(function(){
$(this).toggleClass("pause");
if(audio.paused){
audio.play();
timer();
}else{
audio.pause();
}
});
audio.addEventListener("ended", function(){
$.post("php/player.php", function(result){
audio.src = result;
});
audio.play(); // here is the problem
timer();
});
});
和HTML:
<div id="player">
<div id="controls" class="play"></div>
<div id="music-title">
<div id="slider">
<div id="wrap-music-title">
<p id="music-title">Jamie T - Chaka Demus</p>
</div>
</div>
</div>
<span id="timeleft"></span>
<div id="player-header">
<audio id="audio-player-header" src="music/rock/Jamie T - Chaka Demus.mp3">
</audio>
</div>
</div>
我在stackoverflow和web上找到了一些解决方案,但这里没有任何作用。提前感谢您的帮助。

您创建了一个竞争条件,在您调用ajax之前调用audio.play()
。您可以(A)听取音频canplay
事件然后触发播放或(B)只设置音频标签的autoplay
属性。
选项A:
audio.addEventListener("ended", function(){
$.post("php/player.php", function(result){
audio.src = result;
});
});
audio.addEventListener("canplay", function(){
audio.play();
});
选项B:
<audio autoplay id="audio-player-header" src="music/rock/Jamie T - Chaka Demus.mp3">
