此代码将在获取幕帘时间并显示通知栏十分钟后执行。
我想在登录系统中使用此代码。当用户在特定时间登录时,它会显示通知栏。但是如果用户在一定时间后但在十分钟内登录,我想查看通知栏 例如 如果登录时间是一定时间后的两分钟,则会显示8分钟的通知栏。
是否可能以及如何?
(function () {
function checkTime(i) {
return (i < 10) ? "0" + i : i;
}
function startTime() {
var today = new Date(),
h = checkTime(today.getHours()),
m = checkTime(today.getMinutes()),
s = checkTime(today.getSeconds());
// ms = checkTime(today.getMilliseconds());
document.getElementById('time').innerHTML = h + ":" + m + ":" + s;
t = setTimeout(function () {
startTime()
}, 1000);
if(h==16 && m==52 && s==00 )
{
alertify.notify('sample', 'success', 60, function(){ console.log('dismissed'); });
}
else if(h==17 && m==01 && s==00 )
{
alertify.notify('difficult', 'success', 60, function(){ console.log('dismissed'); });
}
}
startTime();
})();

答案 0 :(得分:0)
简单的数学:
秒钟10分钟= 600;
timeElapsed = currenttime - timeToAlert;
if ((timeElapsed >=0) && (timeElapsed <600)){
//show the alert
timeToShowAlert = 600-timeElapsed;
showAlertForTime(timeToShowAlert);
}
