Yandex metrica, how to do without the counter number (yaCounter000000.reachGoal -> yaCounter.reachGoal)?

Question

Yandex

The question arose of setting up analytics and goals on many sites.
How can you do without the counter number to call the API functions?
Reformat yaCounter000000 into a single record where you don't have to substitute the counter number all the time?
yaCounter000000.reachGoal() -> yaCounter.reachGoal();

Answer 1

I asked the question myself and I will answer it myself)
I found the solution:

function metrikaReach(goal_name) {
  for (var i in window) {
    if (/^yaCounter\d+/.test(i)) {
      window[i].reachGoal(goal_name);
    }
  }
}

And in ajax submitting the form I call the function metricaReach(formName);
