Doing a javascript confirm on logout i will show u how

Ok so this is a very easy JavaScript u can use to confirm a logout and if u hit cancel then it will not logout and if you hit ok it will scripts below

<script language="JavaScript" type="text/javascript">
function confirmLogout(){
var agree = confirm("Are you sure you wish to logout?");

if(agree){
return true;

}else{

return false;

}
}
</script>

And an example of how u would use this on a link is

<a href="logout.php" onClick="return confirmLogout()">Logout</a>

Hope someone finds this JavaScript of mine useful cheers
