jscript header重新加载同一页面

Question

In my PHP site, I am using script alert for checking invalid username and password. If username and password are wrong, it shows a message box. When I click ok to it, user will be redirected to index.php page. But I want reload same page, like header('Location: '.$_SERVER['PHP_SELF']);.

This is my code :

echo "<script>alert('Invalid Username and Password'); 
location.href='index.php';
</script>";

Answer 1

You can use location.reload()

echo "<script>alert('Invalid Username and Password'); location.reload();</script>";

the reload() function also has an optional parameter:

• false - Default. Reloads the current page from the cache.
• true - Reloads the current page from the server
