Javascript 功能活动超时不起作用

这是我的活动超时功能，但不起作用。我需要帮助才能知道原因，谢谢

首先，函数询问用户是否在这里：

function activityTimeout(){
        //$("#jquery_jplayer").jPlayer("pause");

        clearTimeout(activityTO);

        blockInfoMsg('Are you here?.<br>(Automatic quit in <span id="spanActTO">60</span>seconds)<br><br><input type="button" value="Im here!" onclick="javascript:renewActivityTimeoutUnblock()" class="inputButton">&nbsp;or&nbsp;<input type="button" value="Quit Now!" onclick="javascript:abandonCorrection()" class="inputButton">', 0);

        popupTO = setTimeout(abandonCorrection, 60000);
    }

不能在同一函数中为同一超时清除超时和设置超时，因为函数在调用该函数时执行一次

function renewActivityTimeoutUnblock(){
    $.unblockUI();

    renewActivityTimeout();
}

function stopTimeout(){
    clearTimeout(activityTO);
}

function renewActivityTimeout(){
    clearTimeout(popupTO);

    activityTO = setTimeout(activityTimeout, 1800000);
}

可能您认为它不起作用，因为您可能在javascript控制台中未定义此错误

确保声明了存储超时的变量

function activityTimeout(){
    window.clearTimeout(activityTO);

    // make sure that this is an existing function in you js code
    blockInfoMsg('Are you here?.<br>(Automatic quit in <span id="spanActTO">60</span>seconds)<br><br><input type="button" value="Im here!" onclick="javascript:renewActivityTimeoutUnblock()" class="inputButton">&nbsp;or&nbsp;<input type="button" value="Quit Now!" onclick="javascript:abandonCorrection()" class="inputButton">', 0);

    // make sure abandonCorrection is an existing function, and this will timeout for 1 minute
    popupTO = window.setTimeout(abandonCorrection, 60000);
}

function renewActivityTimeoutUnblock(){
    $.unblockUI();
    renewActivityTimeout();
}
var activityTo;  // declare this variable like this
var popupTo;   // declare this variable like this

function renewActivityTimeout(){
    window.clearTimeout(activityTO);
    window.clearTimeout(popupTO);

    // take note of your time here it's 1,800,000 ms that's about 30 minutes
    activityTO = window.setTimeout(activityTimeout, 1800000);
}

记下你的时间，activityTimeout将在30分钟后生效。试着把它放低，这样你就能看见了。然后使用警报或控制台日志进行您自己的调试

这里是的一个简短演示，它被延迟了3秒钟，然后出现console.log和警报。希望这对你有帮助

注: 不要混淆setTimeout和setInterval

setTimeout只是一个延迟，只执行一次

另一方面，setInterval就像一个循环，它将在您设置的每个时间间隔内继续调用函数

要了解有关窗口计时器的更多信息

放弃更正和blockInfoMsg是否是现有功能？请尝试使用简单功能，例如alert，检查您的功能是否工作。谢谢！但还是不行！事实上，在您的演示中，续订功能不起作用！这是放弃校正函数：函数放弃校正{window.onbeforeunload=null；window.location.reload；}@QUIEROHACERLO-ehhh？在演示中，您没有看到警报弹出窗口？3秒后显示。在JSFIDLE演示中，它只是代码的一个简短版本，只是为了向您展示SetTimeOutwork是如何工作的，我只看到一次！在我接受警报3秒钟后，什么也没发生@Quierohacero我想你把setTimeout和setInterval搞混了。请阅读我更新的答案。谢谢！是的，我很困惑。我希望在用户不执行任何操作时执行该函数，而不是每3秒或一次自动执行一次。再次感谢！
