<!--
We have the "refresh" meta-tag in case the user's browser does
not correctly support JavaScript or has JavaScript disabled.
Notice that this is nested within a "noscript" block.
-->
<meta http-equiv="refresh" content="10"> //content=10 คือเวลาที่กำหนด
</noscript>
<script language="JavaScript">
<!--
var sURL = unescape(window.location.pathname);
function doLoad()
{
// the timeout value should be the same as in the "refresh" meta-tag
setTimeout( "refresh()", 2*1000 );
}
function refresh()
{
// This version of the refresh function will cause a new
// entry in the visitor's history. It is provided for
// those browsers that only support JavaScript 1.0.
//
window.location.href = sURL;
}
//-->
</script>
<script language="JavaScript1.1">
<!--
function refresh()
{
// This version does NOT cause an entry in the browser's
// page view history. Most browsers will always retrieve
// the document from the web-server whether it is already
// in the browsers page-cache or not.
//
window.location.replace( sURL );
}
//-->
</script>
<script language="JavaScript1.2">
<!--
function refresh()
{
// This version of the refresh function will be invoked
// for browsers that support JavaScript version 1.2
//
// The argument to the location.reload function determines
// if the browser should retrieve the document from the
// web-server. In our example all we need to do is cause
// the JavaScript block in the document body to be
// re-evaluated. If we needed to pull the document from
// the web-server again (such as where the document contents
// change dynamically) we would pass the argument as 'true'.
//
window.location.reload( false );
}
//-->
</script>

<!--
Use the "onload" event to start the refresh process.
-->
<body onload="doLoad()">
<script language="JavaScript">
<!--
// we put this here so we can see something change
document.write('<b>' + (new Date).toLocaleString() + '</b>');
//-->
