slider on change check innerHTML

I am working with slider library (noUIslider). Everything works fine.. except one single thing! i am putting out the slider value in a span and when this changes i needs to fire an specific event. All the changes are visibly in the span but when i try reading it with javascript.. it doesn't work

This is my html

<div id="slider-step"></div>
<span id="slider-step-value"></span>

and this my javascript

var sliderValue = document.getElementById('slider-step-value').innerHTML;

stepSlider.noUiSlider.on('update', function() {
  console.log("change");
  if(sliderValue === "2004"){
    alert("hoi");
  }
});

What am i doing wrong!? thank you guys! :)

It looks like you only check/set the sliderValue variable when the script loads so it's value never updates. Check and set it it inside your on update callback function. Maybe something like this:

var slider = document.getElementById('slider-step-value');
var sliderValue;

stepSlider.noUiSlider.on('update', function() {
  console.log("change");
  // check the slider value in here
  sliderValue = slider.innerHTML;
  if(sliderValue === "2004"){
    alert("hoi");
  }
});
