<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
<script>
let second = +prompt(`请输入秒数`)
function gatTime(t) {
let h = parseInt(t / 60 / 60 % 24)
let m = parseInt(t / 60 % 60)
let s = parseInt(t % 60)
h = h < 10 ? `0` + h : h
m = m < 10 ? `0` + m : m
s = s < 10 ? `0` + s : s
return `转换后的时间为${h}：${m}：${s}`
}
let str = gatTime(second)
document.write(str)
</script>
</body>
</html>运行结果：
