• javascript
• php

• if (confirm("Are you sure?")) { /* do work */ } – SpYk3HH Commented Jan 15, 2014 at 2:48
• Is there a reason you're using the deprecated mysql_* functions? – Mike Commented Jan 15, 2014 at 2:48
• @Mike, gone but not forgotten. Many of us are still on 5.3- meaning their not yet gone methods. I like em better than the new stuff anyway, myself. – SpYk3HH Commented Jan 15, 2014 at 2:49
• @SpYk3HH they're not "gone" in any version yet. They are still in 5.5, just deprecated and will produce a warning if E_DEPRECATED is enabled, and rightfully so. You probably like them because you're used to them, but mysqli is practically no different in its usage. PHP devs didn't just get together one day and say up "hey, let's deprecate stuff". They are deprecated for a reason. – Mike Commented Jan 15, 2014 at 2:54
• @Mike Oh I know the new is better, and I'll adjust eventually. Let's just say my first attempt at molling over a whole site with the i upgrade did not go well, and "no", they don't function just like the old. – SpYk3HH Commented Jan 15, 2014 at 2:56

Most simple:

<a href="logout.php" onclick="return confirm('Are you sure to logout?');">Logout</a>

maybe this is what you are trying to achieve?

var logout = confirm("Are you sure to logout?");

if(logout){
     location.href = "pathtologout.php";
}

If you just need a simple confirmation, you can do this

$('#logout').click(function(){
    var reallyLogout=confirm("Do you really want to log out?");
    if(reallyLogout){
        location.href="path/to/logout/file.php";
    }
});

If you can't use jQuery(!), you can use pure Javascript to attach the event handler

function logout(){
        var reallyLogout=confirm("Do you really want to log out?");
        if(reallyLogout){
            location.href="path/to/logout/file.php";
        }
}
var el = document.getElementById("logout");
if (el.addEventListener) {
        el.addEventListener("click", logoutfunction, false);
    } else {
        el.attachEvent('onclick', logoutfunction);
}
