html5 audio的语法以及属性和方法

使用语法

属性
src 是歌曲的路径
controls 播放控制 如果给标签里写了 controls="controls" 那么网页会显示audio自带的播放控件，如果没写就不会显示.
loop 歌曲循环 在标签里添加该属性歌曲循环 如果你的歌曲是从后台调取的的 也可以在ajax里设置 loop=true/false来控制;
autoplay 当歌曲加载后自动播放，但是只有pc端可以实现 移动端不行(pc端的浏览器要比移动端的完善很多，对有些属性支持也会好很多)
以上是标签内的属性 当然也可以作为对象属性来调取控制auido.*

audio不单单是个标签 他也是window下的一个对象，对象就有属性和方法，作为对象他有哪些常用的方法呢

对象属性：
currentTime 获取当前播放时间
duration 获取歌曲的总时间
play 是否在播放 返回true/false
pause 是否暂停 返回true/false

对象方法：
play() 播放歌曲
pause() 暂停歌曲
load()重新加载歌曲

以上这些属性和方法只是audio最常用的一部分，也是今天的demo里面要用到的，如果想了解更多关于audio的属性和方法可以去w3shool看下http://www.w3school.com.cn/jsref/dom_obj_audio.asp

html5 audio的一些事件

play 播放事件 可判断歌曲是否正在播放中
pause 暂停事件 判断歌曲是否暂停
loadstart，durationchange，loadeddata，progress，canplay，canplaythrough。（这些事件在加载过程中是按以上顺序触发的）
以上这些事件可以通过事件监听对其做相应处理
