I'm working on sliders with the jQuery sliders, I have a inout slider as

<form id="sliderData">
  <input id="slider1" type="range" min="0" max="50" step="">
</form>

I want the slider to set up to only some fixed values as [2,30,20,30,35,45]. So I cannot set up the step value. I have tried to fire the event by this code

$('form#sliderData').change(function () {
    alert("Hello");
});

This event is not even firing.Is there anyway to set slider to random values

The event is not being fired because you need to hook the change event to the slider control itself, not it's parent form.

The problem you have is that you cannot specify specific steps in a slider control. They must all be the same step apart from the min to the max values. To solve this you could instead make the values of the slider match the indexes of the values in your JS array, and have a label showing the actual option chosen. Something like this:

var values = [2, 30, 20, 30, 35, 45];
$('#slider1').on('input', e => $('span').text(values[e.target.value]));

<script src="https://cdnjs.cloudflare./ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="sliderData">
  <input id="slider1" type="range" min="0" max="5" value="0">
  <span>2</span>
</form>
