您可能可以通过检测窗体主体上的鼠标移动并使用最后的移动时间更新全局变量来拼凑一些东西。然后，您需要运行一个间隔计时器，定期检查最后一次移动时间，如果距离检测到最后一次鼠标移动已经足够长，则执行一些操作。

使用普通JavaScript:

var inactivityTime = function () {
    var time;
    window.onload = resetTimer;
    // DOM Events
    document.onmousemove = resetTimer;
    document.onkeydown = resetTimer;

    function logout() {
        alert("You are now logged out.")
        //location.href = 'logout.html'
    }

    function resetTimer() {
        clearTimeout(time);
        time = setTimeout(logout, 3000)
        // 1000 milliseconds = 1 second
    }
};

并在需要的地方初始化函数(例如:onPageLoad)。

window.onload = function() {
  inactivityTime();
}

如果需要，您可以添加更多DOM事件。最常用的有:

document.onload = resetTimer;
document.onmousemove = resetTimer;
document.onmousedown = resetTimer; // touchscreen presses
document.ontouchstart = resetTimer;
document.onclick = resetTimer;     // touchpad clicks
document.onkeydown = resetTimer;   // onkeypress is deprectaed
document.addEventListener('scroll', resetTimer, true); // improved; see comments

或者使用数组注册所需的事件

window.addEventListener('load', resetTimer, true);
var events = ['mousedown', 'mousemove', 'keypress', 'scroll', 'touchstart'];
events.forEach(function(name) {
 document.addEventListener(name, resetTimer, true);
});

记得根据需要使用窗口或文档。下面你可以看到它们之间的区别:在JavaScript中，窗口、屏幕和文档之间的区别是什么?

代码更新了@frank-conijn和@daxchen改进:window。如果滚动是在可滚动元素内，Onscroll将不会触发，因为滚动事件不会冒泡。在窗口。addEventListener('scroll'， resetTimer, true)，第三个参数告诉侦听器在捕获阶段而不是冒泡阶段捕获事件。

纯JavaScript，通过addEventListener正确设置重置时间和绑定:

(function() {

  var t,
    timeout = 5000;

  function resetTimer() {
    console.log("reset: " + new Date().toLocaleString());
    if (t) {
      window.clearTimeout(t);
    }
    t = window.setTimeout(logout, timeout);
  }

  function logout() {
    console.log("done: " + new Date().toLocaleString());
  }
  resetTimer();

  //And bind the events to call `resetTimer()`
  ["click", "mousemove", "keypress"].forEach(function(name) {
    console.log(name);
    document.addEventListener(name, resetTimer);
  });

}());

<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!

类似于Peter J的解决方案(使用jQuery自定义事件)…

// Use the jquery-idle-detect.js script below
$(window).on('idle:start', function() {
  // Start your prefetch, etc. here...
});

$(window).on('idle:stop', function() {
  // Stop your prefetch, etc. here...
});

文件jquery-idle-detect.js

(function($, $w) {
  // Expose configuration option
  // Idle is triggered when no events for 2 seconds
  $.idleTimeout = 2000;

  // Currently in idle state
  var idle = false;

  // Handle to idle timer for detection
  var idleTimer = null;

  // Start the idle timer and bind events on load (not DOM-ready)
  $w.on('load', function() {
    startIdleTimer();
    $w.on('focus resize mousemove keyup', startIdleTimer)
      .on('blur', idleStart) // Force idle when in a different tab/window
      ;
  ]);

  function startIdleTimer() {
    clearTimeout(idleTimer); // Clear prior timer

    if (idle) $w.trigger('idle:stop'); // If idle, send stop event
    idle = false; // Not idle

    var timeout = ~~$.idleTimeout; // Option to integer
    if (timeout <= 100)
      timeout = 100; // Minimum 100 ms
    if (timeout > 300000)
      timeout = 300000; // Maximum 5 minutes

    idleTimer = setTimeout(idleStart, timeout); // New timer
  }

  function idleStart() {
    if (!idle)
      $w.trigger('idle:start');
    idle = true;
  }

}(window.jQuery, window.jQuery(window)))

就像它可以得到的那样简单，检测鼠标移动的时间:

var idle = false;

document.querySelector('body').addEventListener('mousemove', function(e) {
    if(idle!=false)
        idle = false;
});

var idleI = setInterval(function()
{
    if(idle == 'inactive')
    {
        return;
    }

    if(idle == true)
    {
        idleFunction();
        idle = 'inactive';
        return;
    }

    idle = true;
}, 30000); // half the expected time. Idle will trigger after 60 s in this case.

function idleFuntion()
{
   console.log('user is idle');
}
