Essentially, I am trying to track a button using analytics (I'm using Yandex Metrica to do so).

  window.onload = function () {
      onClick = function () {
        var button = document.getElementById('button');

        setGoal = function () {
          ym(54060910, 'reachGoal', 'TEST');
          return true;
        }

        setInterval(setGoal, 50);

        // Unpauses the interval
        restart = function () {
          // This can be an empty function
        }
        button.addEventListener('click', restart, false);
      }
    }

The tracking works fine in modern browsers, but not Opera Mini. I have modelled this function off the one in the above blog post, which is meant to resume paused scripts:

var box = document.getElementById('box'),
	update = document.getElementById('valofnewcol'),
	start = 0;

changecolor = function(element, degreeshift, update) {
	var newcol = (start * degreeshift) / 360 << 8,
	col = 'hsl(' + newcol + ', 100%, 50%)',
	coltxt = document.createTextNode(col),
	anim,
	restart;

	element.style.background = col;
	start++;

	if (update.firstChild) {
		update.replaceChild(coltxt, update.firstChild);
	} else {
		update.appendChild(coltxt);
	}
}

anim = setInterval(changecolor, 50, box, 45, update);

// Unpauses the interval
restart = function(){
	// This can be an empty function
}
box.addEventListener('click', restart, false);

My questions are:

• Is it possible to get tracking for analytics working in Opera Mini using this method?
• And if so, how do I amend my code to achieve that?

P.s I am using Yandex Metrica but I would assume the same principles would apply to Google Analytics.

P.p.s I've asked the same question on Stackoverflow if you'd like to answer there.
