Page Redirect when Scrolling

You can do this simply with JavaScript:

<script>
window.onscroll = function(){  
   location.href = "outra_pagina.html";
}
</script>

For me this is not a good practice because scrollbars are areas on the side of the browser window, which indicate the existence of content that goes beyond the visible area of the page and allows the scrolling of the window to reach it, helping to adapt the window to published content.

In order to be as fast as possible, it is better to do it right on the click, because anyone who goes to Scroll will always want to roll!

var clickedOnScrollbar = function(mouseX){
  if( $(window).outerWidth() <= mouseX ){
    return true;
  }
}

$(document).mousedown(function(e){
  if( clickedOnScrollbar(e.clientX) ){
    window.location = "https://pt.stackoverflow.com/";
  }
});

#a {
height:1200px;
}
