In my case, this rule was to blame:

html,
body { overflow-x: hidden; }

Hiding overflowing elements is fine as long as the rule is applied only to the body element.

Your code works fine if you add an HTML element having height

$(window).scroll(function(){
    var ws = $(window).scrollTop();
   if(ws)
  {
        console.log(ws);
  }
});

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div style="height:1500px"></div>

Try this,

CSS

body{
height:1200px;
}

Jquery

$(window).on('scroll',function(){
    alert('Hi');
});

(or)

  $(window).on('scroll',function(){
        var wstp = $(window).scrollTop();
       if(wstp)
      {
       alert('hi');
      }
    });

Just add height to your body tag and scroll.

If you want to execute or initialize function, you have to write below simple code.

$(window).on("scroll", function() {
   var scrollTop = $(window).scrollTop();
   if(scrollTop >= 10) {
     //here is your function name
   }
});
