clearInterval isn'tworking

Question

I have to clear the interval but I don't know why it isn't working. Normally it schould be quite simple, but I just can't find out whats wrong.

if(data.groupStandings[0].active === true){
  Tabelle();
  var timerId = setInterval(countdown, 1000);
  if(data.groupStandings[0].active === false){
    clearInterval(timerId);
  }
  var timeLeft = 5;       
  function countdown() {
    if (timeLeft < 0) {
      clearTimeout(timerId);
      code();
      timeLeft--;
      if(timeLeft <= -5){
        timeLeft = 5;
      }
    } else {
      code();
      timeLeft--;
    }
  }
}

Why are you trying to clear the interval *immediately* after setting it? Why not just not set it in the first place? Additionally, under what conditions do you ever expect `data.groupStandings[0].active === true` and `data.groupStandings[0].active === false` to *both* be true? — David, Aug 30 '21 at 20:42
You only enter this block if `active === true` and only cancel the interval if `active === false`? — ray, Aug 30 '21 at 20:42

You're entering the case when

data.groupStandings[0].active === true

but trying to clear the interval on the value being false

var timerId = setInterval(countdown, 1000);

if (data.groupStandings[0].active === false) { // here
    clearInterval(timerId);
}

so content of the if block will not be read at all unless data.groupStandings[0].active somehow changes it's state (which is not seen in the code)

I tryed it with an else if but it still won't work how can I fix this? – Marcello Greulich Aug 31 '21 at 21:19
First, you need to check whether `data.groupStandings[0].active` is changing it's value. Then, you need to define the interval before those statements – Aziza Kasenova Aug 31 '21 at 22:46
