How to make the countdown timer change after a day automatically and do not start again after updating the page

I have a page where there is a counter that will restart again after an interval day automatically. I want to do this counter and how can I set the countdown timer that always continues with the countdown if I update the browser?

python 3.x – Countdown on the computer

I want to make a program in piton in that if the user does not execute a certain action in, for example, 30 minutes, he removes himself from the machine. How can I do that "countdown"? How do the programs with a "Trial" license do it? Any help is welcome.

Countdown from 0 to 5 seconds and repeat

What query can I use to activate a countdown of 0 to 5 seconds each time it is run? When I execute a query, the output should be from 0 seconds to 5 seconds and once 5 seconds are done, it should return to 0. When it is executed again, it should start from 0 to 5 seconds. Is it possible to achieve something like this using the SQL query?

redirections – simple redirection with countdown

I would like to redirect visitors to my new website. I would like to show a page in which there is a countdown "will be directed to the new site by 4..5..3..2..1 seconds", but I would like the user to choose if he wants to remain in the old one by clicking in a link, before the countdown expires.
How can I do it practically? My old site is based on Drupal.

javascript – Creating a countdown clock in typed

Only the code is, it gives a date, it will begin to count how many days, hours, minutes and seconds it is emitting an event & # 39; countDown & # 39; and once it reaches 0, the event "expired" is issued.

How can this code be improved?

DateCountDown class {
Listeners: Map <string, Array>;

builder (date: date) {

this.startCountDown (date);
this.listeners = new Map ();
this.listeners.set ("countdown", []);
this.listeners.set ("expired", []);
}

on (eventName: "countDown", listener: (values: CountDownValues) => void);
on (eventName: "expired", listener: (isExpired: boolean) => void);
on (eventName: string, listener: Function) {
this.listeners.get (eventName) .push (listener);
}


startCountDown (date: Date) {
const thousand = 1000;
const sixty = 60;
const twenty-four = 24;

timer const = setInterval (() => {
const now = new Date (). getTime ();
const t = date.valueOf () - now;

const days = Math.floor (t / (thousand * sixty * sixty * twenty-four));
hours const = Mathematics. ((t% (thousand * sixty * sixty * twenty-four)) / (thousand * sixty * sixty));
minutes of const = Math.floor ((t% (thousand * sixty * sixty)) / (thousand * sixty));
seconds of const = Math.floor ((t% (thousand * sixty)) / thousand);

yes t <= 0) {
                clearInterval(timer);
                this.listeners.get("expired").forEach(listener =>
                    listener (true));
he came back;
}

this.listeners.get ("countdown"). forEach (listener =>
listener (new CountDownValues ​​(days, hours, minutes, seconds))
);
}, 1000);
}
}
CountDownValues ​​class {
days: number;
hours: number;
minutes: number;
seconds: number;

constructor (days: number, hours: number, minutes: number, seconds: number) {
this.days = days;
this.hours = hours;
this.minutes = minutes;
this.seconds = seconds;
}

}
var date = new Date ();
date.setSeconds (date.getSeconds () + 20);

let countDown = new DateCountDown (date);

countDown.on ("countDown", values ​​=> {
console.log ("from first", values);
});
countDown.on ("expired", isExpired => {
console.log ("expired:", isExpired);
});

c # – Infinite counters and countdown

I'm refactoring my programmer and for one of its triggers I need an endless counter that automatically restarts. Since this is a simple and very common task, I do not want forever I have to implement it again, so I encapsulated it so that, hopefully, it can be reused. everywhere plus.


The counter is represented by an enumerable interface with a pair or properties that provide information about the counter and the methods that allow interacting with it.

Public interface IInfiniteCounter: IEnumerable<(int Value, InfiniteCounterState State)>
{
int Min {get; }

int Max {get; }

int Length {get; }

int Current {get; }

(int Value, State InfiniteCounterState) Next ();

void Reset ();
}

Uses a enumerate to inform the caller about the type of value and returns New Each time the counter restarts.

public enumeration InfiniteCounterState
{
New,
Following
}

I have an implementation of the interface. the Infinity Counter which is a forward counter:

public class InfiniteCounter: IInfiniteCounter
{
private int _current;

Infinite public accountant (int min, int max)
{
Min = min;
Max = max;
}

Public InfiniteCounter (int max): this (0, max) {}

public int Min {get; }

public int Max {get; }

public int Length => Max - Min;

public int Current => _current + Min;

private bool IsComplete => _current == Length;

public (int Value, InfiniteCounterState State) Next ()
{
yes (it is complete)
{
Restart();
}

return (_current + Min, _current ++ == 0? InfiniteCounterState.New: InfiniteCounterState.Next);
}

restore the public vacuum ()
{
_current = 0;
}

I Public enumerator<(int Value, InfiniteCounterState State)> GetEnumerator ()
{
while (true)
{
yield return Next ();
}
}

IEnumerator IEnumerable.GetEnumerator () => GetEnumerator ();
}

To have it running backwards I created two extensions. One that is an extension for the IInfiniteCounter

public static class InfiniteCounterExtensions
{
IEnumerable static public<(int Value, InfiniteCounterState State)> Countdown (this counter IInfiniteCounter)
{
return counter.Select (x => (x.Value.Flip (counter.Min, counter.Max), x.State));
}
}

and one that is changing the value:

public static class IndexMath
{
Static flip public int (this value int, int min, int max)
{
return (- (value - max + 1)% (max - min)) + min;
}
}

Examples:

main vacuum ()
{
male takes = 4;
new InfiniteCounter (3) .Take (take) .Dump ("0-2");
new InfiniteCounter (3) .Cdowndown (). Take (take) .Dump ("2-0");
new InfiniteCounter (2, 5) .Take (take) .Dump ("2-4");
new InfiniteCounter (2, 5) .Cdowndown (). Take (take) .Dump ("4-2");

0.Flip (0, 3) .Dump ();
1.Flip (0, 3) .Dump ();
}

what do you think about it? It must be convenient to use and each piece must be verifiable. (The argument check will be added later)

Multiple countdown hours in a day and weekly countdown

Greetings to all. I am looking for help to create a countdown table for events that some of them repeat every day at 3 different hours, some of them are repeated on Mondays and Saturdays at 3 different hours, etc.

First of all, what I want is mainly similar to this: https://web.archive.org/web/20130224011532/http://kingofknight.com/times.php

Let's go to the bottom.

1st event: repeated every day at 00:00, 12:00 and 19:00
2nd event: same as the previous one at 02:00, 13:00 and 23:00
3rd event: same as the previous one at 02:00, 14:00 and 21:00
4th event: same as the previous one at 03:00 and 22:00
5th event: same as the previous one at 09:00 and 19:00
6th event: same as the previous one at 07:40 and 22:40
Seventh event: same as the previous one at 10:00 and 21:00
8th event: repeated on Mondays and Saturdays at 06:00, 14:00 and 20:00
Ninth event: repeated on Wednesday at 06:00, 14:00, 20:00
10th event: repeated on Sunday at 8:30 p.m.
11th event: repeated on Friday at 9:00 p.m.

I have created this example table for you to understand it better:
cd.jpg

I want this countdown to repeat itself. The first seven events are repeated every day in two or three hours. When the countdown of the first hour ends, I want to start over. When I finish second, I want third to start. When the last countdown is over, I want the countdown to begin the first hour of the next day. I hope I have explained them well.
SEMrush

I have no idea how to create this. Can you explain it to me like explaining to a mannequin?

unit – WHY !! Does CountDown not work within the IF connection?

I need a way to make the countdown decrease within the if statement. I am accumulating in this problem for more than 3 days. Do not suggest Coroutine because it will not work in my case because I'm using clones (prefabricated started)

I know that the countdown will only work one frame if it is inside an IF statement … Any ideas for it to work … Ty

The game is about cars … and each instantiated car has a random countdown timer

        Null update ()
{
yes (carNumber <cars)
{
SpawnCars ();
}}

and this is the function of spawn

    Empty SpawnCars ()
{
randomSpawnPoint = Random.Range (0, spawnPoints.Length);

randomSpawnCars = Random.Range (0, Cars.Length);

GameObject obj = Instantiate (Cars[randomSpawnCars], spawnPoints[randomSpawnPoint].position, Quaternion.Euler (-90, 180, 0)) as GameObject;

carNumber ++;

obj.gameObject.tag = "select"; // + k;

rcf = obj.GetComponent();
TextMesh txt = FindObjectOfType();

time = random range (4, 20);


txt.text = (time - Time.deltaTime) .ToString ("0");
print (time);
printing (car number);
}
