How to execute a function every n seconds for x seconds?

Question

Layout

There is a function that runs the code every n seconds:

setInterval(function()
{
//некоторые действия функции
},20000);

As if everything is ok, but I need it to stop after x seconds... how to do it?

Answer 1

You can try setting the line-height

Answer 2

let timer = setInterval(callback, 20000);
setTimeout(clearInterval, 15 * 60 * 1000, timer); // setInterval остановится через 15 минут

Answer 3

Set a counter variable that will record the total elapsed time :). Then turn off the counter :)

Here is an example of calculating the delay:

let start = Date.now();
let times = [];

setTimeout(function run() {
  times.push(Date.now() - start); // запоминаем задержку от предыдущего вызова

  if (start + 100 < Date.now()) alert(times); // показываем задержку через 100 мс
  else setTimeout(run); // если нужно ещё запланировать
});

just twist it
