用checkbox控制音乐的暂停与播放，同时音乐要循环播放（可以利用它当个报警提醒喔）

<head runat="server">
<title></title>
<script language="javascript" type="text/javascript">
function play()
{
if (document.getElementById("Checkbox1").checked)
{
document.WMPlay.controls.currentPosition = 0;
document.WMPlay.controls.play();
document.WMPlay.settings.setMode("loop", true);
}
else
{
document.WMPlay.controls.Stop();
}
}
</script>
</head>
<body>
<form id="form1" runat="server">

<input id="Checkbox1" type="checkbox" onclick="play();" />
