hide url bar on mobile browsers

hideURL.js

// hide url bar

(function() {
    
  var win = window,
      doc = win.document;

  // If there's a hash, or addEventListener is undefined, stop here
  if ( !location.hash || !win.addEventListener ) {

    //scroll to 1
    window.scrollTo( 0, 1 );
    var scrollTop = 1,

    //reset to 0 on bodyready, if needed
    bodycheck = setInterval(function(){
      if( doc.body ){
        clearInterval( bodycheck );
        scrollTop = "scrollTop" in doc.body ? doc.body.scrollTop : 1;
        win.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
      } 
    }, 15 );

    if (win.addEventListener) {
      win.addEventListener("load", function(){
        setTimeout(function(){
          //reset to hide addr bar at onload
          win.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
        }, 0);
      }, false );
    }
  }

})();

This doesn't work anymore.
