The simple audio playback implemented based on html5 is quite good and can be used as a reference. The code is below
<!doctype html>
<html lang="en">

<script>
$(function() {
getSong();
})
//获取歌曲链接并插入dom中
function getSong() {
var audio = document.getElementById("audio");
audio.src = "http://frontman.qiniudn.com/songnotime.mp3";
audio.loop = true; //歌曲循环
playCotrol(); //播放控制函数
}
//点击播放/暂停
function clicks() {
var audio = document.getElementById("audio");
$("#control").click(function() {
if ($("#control").hasClass("play")) {
$("#control").addClass("pause").removeClass("play");
audio.play();//开始播放
dragMove();//并且滚动条开始滑动
$("#control").html("暂停播放");
} else {
$("#control").addClass("play").removeClass("pause");
$("#control").html("点击播放");
audio.pause();
}
})
}
//播放时间
function timeChange(time, timePlace) {//默认获取的时间是时间戳改成我们常见的时间格式
var timePlace = document.getElementById(timePlace);
//分钟
var minute = time / 60;
var minutes = parseInt(minute);
if (minutes < 10) {
minutes = "0" + minutes;
}
//秒
var second = time % 60;
seconds = parseInt(second);
if (seconds < 10) {
seconds = "0" + seconds;
}
var allTime = "" + minutes + "" + ":" + "" + seconds + ""
timePlace.innerHTML = allTime;
}
//播放事件监听
function playCotrol() {
audio.addEventListener("loadeddata", //歌曲一经完整的加载完毕( 也可以写成上面提到的那些事件类型)
function() {
$("#control").addClass("play").removeClass("color_gray");
$("#control").html("点击播放");
addListenTouch(); //歌曲加载之后才可以拖动进度条
var allTime = audio.duration;
timeChange(allTime, "allTime");
setInterval(function() {
var currentTime = audio.currentTime;
$("#time .currentTime").html(timeChange(currentTime, "currentTime"));
}, 1000);
clicks();
}, false);
audio.addEventListener("pause",
function() { //监听暂停
$("#control").addClass("play").removeClass("pause");
$("#control").html("点击播放");
if (audio.currentTime == audio.duration) {
audio.stop();
audio.currentTime = 0;
}
}, false);
audio.addEventListener("play",
function() { //监听暂停
$("#control").addClass("pause").removeClass("play");
$("#control").html("暂停播放");
dragMove();
}, false);
audio.addEventListener("ended", function() {
alert(0)
}, false)
}
//进度条
这里我用的是事件实现进度拖动 如果不太熟悉touch的可以看下我之前写的一个小demo http://www.cnblogs.com/leinov/p/3701951.html
var startX, x, aboveX = 0; //触摸时的坐标 //滑动的距离 //设一个全局变量记录上一次内部块滑动的位置
//1拖动监听touch事件
function addListenTouch() {
document.getElementById("drag").addEventListener("touchstart", touchStart, false);
document.getElementById("drag").addEventListener("touchmove", touchMove, false);
document.getElementById("drag").addEventListener("touchend", touchEnd, false);
var drag = document.getElementById("drag");
var speed = document.getElementById("speed");
}
//touchstart,touchmove,touchend事件函数
function touchStart(e) {
e.preventDefault();
var touch = e.touches[0];
startX = touch.pageX;
}
function touchMove(e) { //滑动
e.preventDefault();
var touch = e.touches[0];
x = touch.pageX - startX; //滑动的距离
//drag.style.webkitTransform = 'translate(' + 0+ 'px, ' + y + 'px)'; //也可以用css3的方式
drag.style.left = aboveX + x + "px"; //
speed.style.left = -((window.innerWidth) - (aboveX + x)) + "px";
}
function touchEnd(e) { //手指离开屏幕
e.preventDefault();
aboveX = parseInt(drag.style.left);
var touch = e.touches[0];
var dragPaddingLeft = drag.style.left;
var change = dragPaddingLeft.replace("px", "");
numDragpaddingLeft = parseInt(change);
var currentTime = (numDragpaddingLeft / (window.innerWidth - 30)) * audio.duration;//30是拖动圆圈的长度，减掉是为了让歌曲结束的时候不会跑到window以外
audio.currentTime = currentTime;
}
//3拖动的滑动条前进
function dragMove() {
setInterval(function() {
drag.style.left = (audio.currentTime / audio.duration) * (window.innerWidth - 30) + "px";
speed.style.left = -((window.innerWidth) - (audio.currentTime / audio.duration) * (window.innerWidth - 30)) + "px";
}, 500);
}
