我创建了一个小的库来做这个:

https://github.com/shawnmclean/Idle.js

描述:

微小的JavaScript库报告用户在浏览器中的活动 (离开，空闲，没有看网页，在不同的标签，等)。这是独立的 其他JavaScript库，如jQuery。

Visual Studio用户可以从NuGet通过:

Install-Package Idle.js

下面是一个在Angular中完成的AngularJS服务。

/* Tracks now long a user has been idle.  secondsIdle can be polled 
   at any time to know how long user has been idle. */
fuelServices.factory('idleChecker',['$interval', function($interval){
    var self = {
        secondsIdle: 0,
        init: function(){
            $(document).mousemove(function (e) {
                self.secondsIdle = 0;
            });
            $(document).keypress(function (e) {
                self.secondsIdle = 0;
            });
            $interval(function(){
                self.secondsIdle += 1;
            }, 1000)
        }
    }
    return self;
}]);

请记住，这个空闲检查器将为所有路由运行，因此应该在angular应用程序加载时在.run()中初始化它。然后你可以使用idleChecker。在每个路由内的secondside。

myApp.run(['idleChecker',function(idleChecker){
    idleChecker.init();
}]);

试试这段代码。它工作得很完美。

var IDLE_TIMEOUT = 10; //seconds
var _idleSecondsCounter = 0;

document.onclick = function () {
    _idleSecondsCounter = 0;
};

document.onmousemove = function () {
    _idleSecondsCounter = 0;
};

document.onkeypress = function () {
    _idleSecondsCounter = 0;
};

window.setInterval(CheckIdleTime, 1000);

function CheckIdleTime() {
    _idleSecondsCounter++;
    var oPanel = document.getElementById("SecondsUntilExpire");
    if (oPanel)
        oPanel.innerHTML = (IDLE_TIMEOUT - _idleSecondsCounter) + "";
    if (_idleSecondsCounter >= IDLE_TIMEOUT) {
        alert("Time expired!");
        document.location.href = "SessionExpired.aspx";
    }
}

对于其他有同样问题的用户。这是我刚编的一个函数。

它不会在用户每次鼠标移动时运行，也不会在每次鼠标移动时清除计时器。

<script>
// Timeout in seconds
var timeout = 10; // 10 seconds

// You don't have to change anything below this line, except maybe
// the alert('Welcome back!') :-)
// ----------------------------------------------------------------
var pos = '', prevpos = '', timer = 0, interval = timeout / 5 * 1000;
timeout = timeout * 1000 - interval;

function mouseHasMoved(e){
    document.onmousemove = null;
    prevpos = pos;
    pos = e.pageX + '+' + e.pageY;
    if(timer > timeout){
        timer = 0;
        alert('Welcome back!');
    }
}

setInterval(function(){
    if(pos == prevpos){
        timer += interval;
    }else{
        timer = 0;
        prevpos = pos;
    }
    document.onmousemove = function(e){
        mouseHasMoved(e);
    }
}, interval);
</script>

JavaScript没有办法告诉CPU的使用情况。这将打破运行在沙盒中的JavaScript。

除此之外，连接页面的onmouseover和onkeydown事件可能会工作。

你也可以在onload事件中使用setTimeout来调度延迟后调用的函数。

// Call aFunction after 1 second
window.setTimeout(aFunction, 1000);

根据equiman提供的输入:

class _Scheduler {
    timeoutIDs;

    constructor() {
        this.timeoutIDs = new Map();
    }

    addCallback = (callback, timeLapseMS, autoRemove) => {
        if (!this.timeoutIDs.has(timeLapseMS + callback)) {
            let timeoutID = setTimeout(callback, timeLapseMS);
            this.timeoutIDs.set(timeLapseMS + callback, timeoutID);
        }

        if (autoRemove !== false) {
            setTimeout(
                this.removeIdleTimeCallback, // Remove
                10000 + timeLapseMS, // 10 secs after
                callback, // the callback
                timeLapseMS, // is invoked.
            );
        }
    };

    removeCallback = (callback, timeLapseMS) => {
        let timeoutID = this.timeoutIDs.get(timeLapseMS + callback);
        if (timeoutID) {
            clearTimeout(timeoutID);
            this.timeoutIDs.delete(timeLapseMS + callback);
        }
    };
}

class _IdleTimeScheduler extends _Scheduler {
    events = [
        'load',
        'mousedown',
        'mousemove',
        'keydown',
        'keyup',

        'touchstart',
        'touchend',
        'touchcancel',
        'touchmove',
    ];
    callbacks;

    constructor() {
        super();
        this.events.forEach(name => {
            document.addEventListener(name, this.resetTimer, true);
        });

        this.callbacks = new Map();
    }

    addIdleTimeCallback = (callback, timeLapseMS) => {
        this.addCallback(callback, timeLapseMS, false);

        let callbacksArr = this.callbacks.get(timeLapseMS);
        if (!callbacksArr) {
            this.callbacks.set(timeLapseMS, [callback]);
        } else {
            if (!callbacksArr.includes(callback)) {
                callbacksArr.push(callback);
            }
        }
    };

    removeIdleTimeCallback = (callback, timeLapseMS) => {
        this.removeCallback(callback, timeLapseMS);

        let callbacksArr = this.callbacks.get(timeLapseMS);
        if (callbacksArr) {
            let index = callbacksArr.indexOf(callback);
            if (index !== -1) {
                callbacksArr.splice(index, 1);
            }
        }
    };

    resetTimer = () => {
        for (let [timeLapseMS, callbacksArr] of this.callbacks) {
            callbacksArr.forEach(callback => {
                // Clear the previous IDs
                let timeoutID = this.timeoutIDs.get(timeLapseMS + callback);
                clearTimeout(timeoutID);

                // Create new timeout IDs.
                timeoutID = setTimeout(callback, timeLapseMS);
                this.timeoutIDs.set(timeLapseMS + callback, timeoutID);
            });
        }
    };
