需要用到location對象里的reload()方法。語法是：location.reload()
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">

<script>
var mynum=Math.random();
Math.round(mynum*10);
document.write(Math.round(mynum*10));
function contxt()
{
location.reload();
}
</script>
</head>
<body>
<button type="button" onclick="contxt()">點擊這里</button>
