basic web page redirect or reload

The following is a basic web page redirect;

<html>
  <head>
    <meta HTTP-EQUIV="refresh" CONTENT="3; URL=index.html">
  </head>
</html>

 
The following is a basic javascript equivalent;
 
<script>
setTimeout(function () 
{
   // 5 seconds
   window.location.href= 'index.html';
}, 5000);
</script>
 
 
 
To reload a page without getting an alert, we can do the following;
 
<script>
    function reload_page()
    {
        window.location = window.location.href;
    }
</script>
 
then call it by;
 
<script type="text/javascript">
     reload_page();
</script>';
 
or from php;
 
echo '<script type="text/javascript">'.'reload_page();'.'</script>';


To call the function after some time, for example, to refresh the page in 5 seconds, we can do the following to call the reload_page function detailed above;


<script>
setTimeout(reload_page,5000);
</script>
