我想添加一个按钮,让用户在mp3播放器中收听歌曲30秒,但我不能这样做。我正在玩这个几个小时,这是我使用的http://tympanus.net/codrops/2012/12/04/responsive-touch-friendly-audio-player。我已经得到了什么
返回30秒的代码
// jump 30 seconds back when we click the button
$('.audioplayer-back30s').click(function(){
var audio = $('audio');
var backToSec = audio.currentTime - 30;
// make sure that we jump to a valid point in time
audio.currentTime = (backToSec >= 0) ? backToSec : 0;
});

此mp3播放器的其余css和js文件位于http://tympanus.net/Development/AudioPlayer/AudioPlayer.zip。真的我没有任何想法,我真的需要这个功能,最大的问题是创建只是按钮。谢谢你们的回复。

您需要绑定timeupdate
事件
<强> 实施例 强>
var audio = $('audio');
audio.on('timeupdate',function() {
var time = Math.floor(this.currentTime);
if (time > 5) {
this.currentTime = 0;
}
});
