解决html5 audio iphone,ipd，safari不能自动播放问题

html audio 在iPhone，ipd,safari浏览器不能播放是有原因滴
(在safri on ios里面明确指出等待用户的交互动作后才能播放media，也就是说如果你没有得到用户的action就播放的话就会被safri拦截)

找了很多资料都没有解决，不过最终在国外网站通过翻译解决问题，希望能帮到没有解决此问题的童鞋
附带源码如下：黑色部分表示重点突出

var g_audio = window.g_audio = new Audio(); //创建一个audio播放器
var g_event = window.g_event =new function(){
var events = ['load','abort','canplay','canplaythrough',
'durationchange','emptied','ended','error',
'loadeddata','loadedmetadata','loadstart',
'pause','play','playing','progress',
'ratechange','seeked','seeking','stalled',
'suspend','timeupdate','volumechange','waiting', 'mediachange'];
g_audio.loop = false;
g_audio.autoplay = true;
g_audio.isLoadedmetadata = false;
g_audio.touchstart = true;
g_audio.audio = true;
g_audio.elems = {};
g_audio.isSupportAudio = function(type){
type=type||”audio/mpeg”;
try{
var r=g_audio.canPlayType(type);
return g_audio.canPlayType&&(r==”maybe”||r==”probably”)
}catch(e){return false;}
};
g_audio.push = function(meta){
g_audio.previousId = g_audio.id;
g_audio.id = meta.song_id;
g_audio.previousSrc = g_audio.src;
g_audio.previousTime = 0.00;
g_audio.src = g_audio.currentSrc = meta.song_fileUrl;
g_audio.isLoadedmetadata = false;
g_audio.autobuffer = true;
g_audio.load();
g_audio.play();
if(g_audio.previousSrc !== g_audio.src){
g_audio.play();
}
};
for(var i = 0, l = events.length; i < l; i++){
(function(e){
var fs = [];
this[e] = function(fn){
if(typeof fn!== ‘function’){
for (var k = 0; k<fs.length; k++){
fs[k].apply(g_audio);
}
return ;
}
fs.push(fn);
g_audio.addEventListener(e, function(){
fn.apply(this);
});
};
}).apply(this, [events[i]]);
}
this.ended(function(){ //播放结束
});
this.load(function(){ //加载
this.pause();
this.play();
});
this.loadeddata(function(){
this.pause();
this.play();
});
this.loadedmetadata(function(){
this.isLoadedmetadata = true;
});
this.error(function(){ //请求资源时遇到错误
});
this.pause(function(){ //歌曲暂停播放
});
this.play(function(){ //歌曲播放
});
};
$$$$(document).ready(function(){
if(/i(Phone|P(o|a)d)/.test(navigator.userAgent)){
$$$$(document).one(‘touchstart’, function (e) {
g_audio.touchstart = true;
g_audio.play();
g_audio.pause();
return false;
});
}
});
audio使用:
$$$$(“#main”).unbind(“click”).bind(“click”,function(){
//gid 表示歌曲id,只是一个表示，没有值不影响播放
//song_fileUrl :播放歌曲地址，不能为空，有效地址
g_audio.elems["id"] = gid;
g_audio.push({song_id:gid,song_fileUrl:json.URL});
});//绑定事件
