Question

我有退出页面的PHP代码，但如果我点击导航框退出，我需要首先弹出一个确认框...如果我想退出或者不...可以帮助我吗？请

代码：

<?php
include("connection.php");


// Delete certain session
unset($_SESSION['username']);
// Delete all session variables
// session_destroy();
$uid = $_POST['uid'];
    $stat="UPDATE users SET status='logout'";
        mysql_query($stat); 
// Jump to login page
header('Location: index.php');


?>

Answer 1

也许这就是你想要实现的目标？

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

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

Answer 2

最简单：

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

Answer 3

如果您只需要一个简单的确认，就可以这样做

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

如果你不能使用jQuery（！），你可以使用纯Javascript来附加事件处理程序

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);
}

在javascript中注销确认框
