Suppose my url is http://example.com#example.org i want to redirect my current tab "example.com" after 5 sec to query parameter "example.org"
<head>
<title></title>
<script type="text/javascript">
var x = window.location.hash.substr(1);
</script>
<meta http-equiv="refresh" content="4;url=x"/>
</head>
<body>
</body>
Instead of using a meta tag to refresh, you should just use Javascript with a timeout to handle the redirect instead. A metatag cannot get a value passed in from Javascript using the approach you have.
<script type="text/javascript">
setTimeout(function() {
window.location.href = window.location.hash.substr(1);
}, 5000);
</script>
Alternative approach, using script to write your metatag:
<head>
<script type="text/javascript">
var x = window.location.hash.substr(1);
document.write("<meta http-equiv=\"refresh\" content=\"4;URL='" + x + "'\"/>");
</script>
</head>
