}
var initAudio = function(){
//audio = document. createElement("audio")
//audio.src='Never Say Good Bye.ogg'
audio = document.getElementById('audio');
}
function getCurrentTime(id){
alert(parseInt(audio.currentTime) ': seconds');
}

function playOrPaused(id,obj){
if(audio.paused){
audio. play();
obj.innerHTML='pause';
return;
}
audio.pause();
obj.innerHTML='play';
}

function hideOrShowControls(id,obj){
if(audio.controls){
audio.removeAttribute('controls');
obj.innerHTML = 'Show control box'
return ;
}
audio.controls = 'controls';
obj.innerHTML = 'Hide control box'
return;
}
function vol(id,type, obj){
if(type == 'up'){
var volume = audio.volume 0.1;
if(volume >=1 ){
volume = 1 ;

}
audio.volume = volume;
}else if(type == 'down'){
var volume = audio.volume - 0.1;
if(volume <=0 ){
volume = 0 ;
}
audio.volume = volume;
}
document.getElementById('nowVol').innerHTML = returnFloat1(audio.volume);
}
function muted(id,obj){
if(audio.muted){
audio.muted = false;
obj.innerHTML = 'Turn on mute';
}else{
audio. muted = true;
obj.innerHTML = 'Turn off mute';
}
}
//Retain one decimal point

function returnFloat1(value) {
value = Math.round(parseFloat(value) * 10) / 10;
if (value.toString().indexOf(".") < 0){
value = value.toString() ".0" ;
}
return value;
}
