我的回答受到了维贾伊的启发，但我认为这是一个更简短、更普遍的解决方案，我想把它分享给可能有帮助的人。

(function () { 
    var minutes = true; // change to false if you'd rather use seconds
    var interval = minutes ? 60000 : 1000; 
    var IDLE_TIMEOUT = 3; // 3 minutes in this example
    var idleCounter = 0;

    document.onmousemove = document.onkeypress = function () {
        idleCounter = 0;
    };

    window.setInterval(function () {
        if (++idleCounter >= IDLE_TIMEOUT) {
            window.location.reload(); // or whatever you want to do
        }
    }, interval);
}());

按照目前的情况，这段代码将立即执行，并在3分钟内没有鼠标移动或按键后重新加载当前页面。

它利用普通的JavaScript和立即调用的函数表达式以一种干净且自包含的方式处理空闲超时。

我写了一个简单的jQuery插件，将做什么你正在寻找。

https://github.com/afklondon/jquery.inactivity

$(document).inactivity( {
    interval: 1000, // the timeout until the inactivity event fire [default: 3000]
    mouse: true, // listen for mouse inactivity [default: true]
    keyboard: false, // listen for keyboard inactivity [default: true]
    touch: false, // listen for touch inactivity [default: true]
    customEvents: "customEventName", // listen for custom events [default: ""]
    triggerAll: true, // if set to false only the first "activity" event will be fired [default: false]
});

脚本将监听鼠标，键盘，触摸和其他自定义事件不活动(空闲)，并触发全局“活动”和“不活动”事件。

我编写了一个小型ES6类来检测活动，并在空闲超时时触发事件。它涵盖了键盘，鼠标和触摸，可以激活和禁用，并且有一个非常精简的API:

const timer = new IdleTimer(() => alert('idle for 1 minute'), 1000 * 60 * 1);
timer.activate();

它不依赖于jQuery，不过您可能需要通过Babel来运行它以支持旧的浏览器。

Debounce其实是个好主意!下面是一个用于无jquery项目的版本:

const derivedLogout = createDerivedLogout(30);
derivedLogout(); // It could happen that the user is too idle)
window.addEventListener('click', derivedLogout, false);
window.addEventListener('mousemove', derivedLogout, false);
window.addEventListener('keyup', derivedLogout, false);

function createDerivedLogout (sessionTimeoutInMinutes) {
    return _.debounce( () => {
        window.location = this.logoutUrl;
    }, sessionTimeoutInMinutes * 60 * 1000 )
}

<script type="text/javascript">
    var idleTime = 0;
    $(document).ready(function () {
        //Increment the idle time counter every minute.
        idleInterval = setInterval(timerIncrement, 60000); // 1 minute

        //Zero the idle timer on mouse movement.
        $('body').mousemove(function (e) {
            //alert("mouse moved" + idleTime);
            idleTime = 0;
        });

        $('body').keypress(function (e) {
            //alert("keypressed"  + idleTime);
            idleTime = 0;
        });

        $('body').click(function() {
            //alert("mouse moved" + idleTime);
            idleTime = 0;
        });
    });

    function timerIncrement() {
        idleTime = idleTime + 1;
        if (idleTime > 10) { // 10 minutes

            window.location.assign("http://www.google.com");
        }
    }
</script>

我认为这个jQuery代码是一个完美的，虽然复制和修改从上面的答案!!

不要忘记在你的文件中包含jQuery库!

我终于把这个工作在我的网站。我发现equiman的回答最有帮助。这个答案的问题是JavaScript中的alert()函数会暂停脚本执行。如果您像我一样希望发送一个警报，然后如果没有收到响应，站点将自动注销，那么暂停执行是一个问题。

解决方案是用自定义除法替换alert()，如下所述。

下面是代码:(注意:您需要更改第58行以重定向到您的站点的适当URL)

var inactivityTracker = function () { // Create an alert division var alertDiv = document.createElement("div"); alertDiv.setAttribute("style","position: absolute;top: 30%;left: 42.5%;width: 200px;height: 37px;background-color: red;text-align: center; color:white"); alertDiv.innerHTML = "You will be logged out in 5 seconds!!"; // Initialise a variable to store an alert and logout timer var alertTimer; var logoutTimer; // Set the timer thresholds in seconds var alertThreshold = 3; var logoutThreshold = 5; // Start the timer window.onload = resetAlertTimer; // Ensure timer resets when activity logged registerActivityLoggers(resetAlertTimer); // ***** FUNCTIONS ***** // // Function to register activities for alerts function registerActivityLoggers(functionToCall) { document.onmousemove = functionToCall; document.onkeypress = functionToCall; } // Function to reset the alert timer function resetAlertTimer() { clearTimeout(alertTimer); alertTimer = setTimeout(sendAlert, alertThreshold * 1000); } // Function to start logout timer function startLogoutTimer() { clearTimeout(logoutTimer); logoutTimer = setTimeout(logout, logoutThreshold * 1000); } // Function to logout function sendAlert() { // Send a logout alert document.body.appendChild(alertDiv); // Start the logout timer startLogoutTimer(); // Reset everything if an activity is logged registerActivityLoggers(reset); } // Function to logout function logout(){ //location.href = 'index.php'; } // Function to remove alert and reset logout timer function reset(){ // Remove alert division alertDiv.parentNode.removeChild(alertDiv); // Clear the logout timer clearTimeout(logoutTimer); // Restart the alert timer document.onmousemove = resetAlertTimer; document.onkeypress = resetAlertTimer; } }; <html> <script type="text/javascript" src="js/inactivityAlert.js"></script> <head> <title>Testing an inactivity timer</title> </head> <body onload="inactivityTracker();" > Testing an inactivity timer </body> </html>
