jQuery MP3播放器：如何在播放另一个时停止所有正在运行的实例
我制作了一个播放MP3的jQuery脚本，但是当我播放第一首MP3而不是播放另一首时，这两首MP3一起播放。
如何停止MP3的所有实例，然后播放选定的播放器？
这是我的代码：
(function($){
$.fn.roundedplayer = function(gopt){
return this.each(function(){
var $this = $(this);
var opt = $.extend({
color: '#e56d49',
radius: 200,
lineWidth: 10,
padding : 6,
shadowBlur:20,
},gopt);
opt.radius = $this.data('radius')?$this.data('radius'):opt.radius;
opt.color = $this.data('color')?$this.data('color'):opt.color;
var $div = $('').attr('class',$this.attr('class')).css({position:'relative',width:opt.radius*2+opt.shadowBlur*2,height:opt.radius*2+opt.shadowBlur*2});
var $canvas = $('');
var $canvas2 = $('');
var ctx = $canvas[0].getContext("2d");
var $img = $('');
var isPlaying = false;
var audio = $this[0];
$this.wrap($div);
$this.after($canvas2).after($canvas).after($img);
/**
* CSS
**/
$canvas.css({position:'absolute', top:0, left:0});
$canvas2.css({position:'absolute', top:0, left:0});
$img.css({position:'absolute',
top: opt.shadowBlur + opt.padding + opt.lineWidth/2,
left: opt.shadowBlur + opt.padding + opt.lineWidth/2,
width: (opt.radius - opt.lineWidth/2 - opt.padding) * 2,
height: (opt.radius - opt.lineWidth/2 - opt.padding) * 2,
borderRadius: (opt.radius - opt.lineWidth/2 - opt.padding) * 2,
boxShadow: "inset 0px 0px 10px #000"
});
$img.animate({boxShadow: "inset 0px 0px 10px #000"})
/**

ctx.beginPath();
ctx.arc(opt.radius + opt.shadowBlur, opt.radius + opt.shadowBlur, opt.radius - opt.lineWidth/2 - opt.padding - 2, 0, Math.PI*2, true);
ctx.closePath();
ctx.lineWidth = opt.lineWidth + opt.padding*2;
ctx.strokeStyle = "#FFFFFF";
ctx.shadowColor="rgba(0,0,0,0.4)";
ctx.shadowBlur = 20;
ctx.stroke();
/**

var $play = $('').css({position:'absolute', left:opt.radius + opt.shadowBlur - 60,top:opt.radius + opt.shadowBlur - 60,cursor:'pointer',opacity:0.6});
$(this).parent().append($play);
var ctx = $play[0].getContext("2d");
$play.draw = function(state){
$play[0].width = $play.width();
var ctx = $play[0].getContext("2d");
ctx.beginPath();
ctx.arc(60,60,50,0,2*Math.PI,true);
ctx.lineWidth = 5;
ctx.strokeStyle = '#FFF';
ctx.fillStyle = "rgba(0,0,0,0.8)";
ctx.fill();
ctx.stroke();
if(state == 'play'){
ctx.beginPath();
ctx.moveTo(40,29);
ctx.lineTo(90,60);
ctx.lineTo(40,91);
ctx.fillStyle = "#FFFFFF";
ctx.fill();
}else{
ctx.beginPath();
ctx.moveTo(45,37);
ctx.lineTo(45,80);
ctx.moveTo(75,37);
ctx.lineTo(75,80);
ctx.lineWidth = 15;
ctx.strokeStyle = '#FFF';
ctx.stroke();
}
}
/**

var csize = opt.lineWidth/2+opt.padding+3;
var $cursor = $('').css({
position:'absolute',
top:0,
left:0,
marginLeft:-csize,
marginTop:-csize
});
$this.parent().append($cursor);
var ctx = $cursor[0].getContext('2d');
ctx.beginPath();
ctx.arc(csize,csize,csize,0,2*Math.PI,true);
ctx.shadowColor="rgba(0,0,0,0.4)";
ctx.shadowBlur = 5;

ctx.shadowOffsetY = 2;
ctx.fillStyle = "#EEE";
ctx.fill();
ctx.beginPath();
ctx.arc(csize,csize,opt.lineWidth/2,0,2*Math.PI,true);
ctx.fillStyle = "#585858";
ctx.fill();
/**

function drawInner(percent){
var ctx = $canvas2[0].getContext("2d");
var p = percent/100;
var radius = opt.radius + opt.shadowBlur;
// Le fond blanc
ctx.beginPath();
ctx.arc(radius, radius, opt.radius - opt.lineWidth/2 - opt.padding - 2, 5*Math.PI/2, 9*Math.PI/2, false);
ctx.lineWidth = opt.lineWidth;
ctx.strokeStyle = "#ededed";
ctx.stroke();
// La progression
ctx.beginPath();
ctx.arc(radius, radius, opt.radius - opt.lineWidth/2 - opt.padding - 2, 5*Math.PI/2, (5+4*p)*Math.PI/2, false);
ctx.lineWidth = opt.lineWidth;
ctx.strokeStyle = opt.color;
ctx.stroke();
// Ombre sur la progression
for( var i=1; i radius || Math.abs(y) > radius){
return false;
}
var a = Math.atan2(x,y);
a = (2 - a/(Math.PI/2))/4;
$canvas2[0].width = $canvas2.width();
audio.currentTime = audio.duration * a;
drawInner(a*100);
if(!isPlaying){
$play.trigger('click');
}
})
$play.hover(function(){
$play.stop().fadeTo(500,1);
},function(){
$play.stop().fadeTo(500,0.6)
}).click(function(event){
event.preventDefault();
if(isPlaying){
isPlaying = false;
$this[0].pause();
}else{
isPlaying = true;
$this[0].play();
$this[0].volume = 0.2;
}
$play.draw(isPlaying?'pause':'play')
}).draw('play');
});
}
})(jQuery);
1：如何解决这个问题？
2：我还有一个问题，因为MP3已经结束了，当我想再次播放时，我必须点击一次暂停/播放才能重新初始化播放器，另一次暂停/播放播放MP3。 我可以修改吗？
