尝试用新方法解决问题并完成它。

<html>
<head>
    <script>

            var t = parseFloat(3600000);

            var myvar=setInterval(myfunc,1000);

            function myfunc()
            {
            if(t>0)
            {
            var seconds = parseFloat(Math.floor( (t/1000) % 60 ).toString());
            var minutes = parseFloat(Math.floor( (t/1000/60) % 60 ).toString());
            var hours = Math.floor( (t/(1000*60*60)) % 24 );
            var days = Math.floor( t/(1000*60*60*24) );
            document.getElementById("div1").innerHTML=minutes+":"+seconds;

            t=t-1000;
            };}
    </script>
</head>
<body>
<p id="demo"></p>
<div id="div1"></div>
