Anchor link scrolls to anchor, but then snaps back to top of page

When you click the “New to SketchUp?” button, the page scrolls down, but then snaps back to the top of the page after a second.

How do I fix this?

Hello @Bizfound,

Thanks for writing in! You are having the issue because you have added this custom JS code:

jQuery(document).ready(function($) {

  var $body                = $('body');
  var bodyHeight           = $body.outerHeight();
  var adminbarHeight       = $('#wpadminbar').outerHeight();
  var navbarFixedTopHeight = 70;
  var locHref              = location.href;
  var locHashIndex         = locHref.indexOf('#');
  var locHash              = locHref.substr(locHashIndex);
  var dragging             = false;
  
  $body.on('touchmove', function() {
      dragging = true;
  } );
  
  $body.on('touchstart', function() {
      dragging = false;
  } );


  //
  // Calculate the offset height for various elements and remove it from
  // the elements top offset so that fixed elements dont cover it up.
  //

  function animateOffset( element, ms, easing ) {
    $('html, body').animate({
      scrollTop: $(element).offset().top - adminbarHeight - navbarFixedTopHeight + 1
    }, ms, easing);
  }


  //
  // Page load offset (if necessary).
  //

  $(window).load(function() {
    if ( locHashIndex !== -1 && $(locHash).length ) {
      animateOffset(locHash, 1, 'linear');
    }
  });


  //
  // Scroll trigger.
  //

  $('a[href*="#"]').unbind('touchend click').bind('touchend click', function(e) {
      console.log($('.hm1.x-bar-fixed').outerHeight());
    href        = $(this).attr('href');
    notComments = href.indexOf('#comments') === -1;
    if ( href !== '#' && notComments ) {
      var theId = href.split('#').pop();
      var $el   = $('#' + theId);
      if ( $el.length > 0 ) {
        e.preventDefault();
        
        if (dragging) {
            return;
        }
        
        animateOffset($el, 850, 'easeInOutExpo');
      }
    }
  });
});

Please temporarily remove the JS code and test your button again. You may need to contact the creator of your JS code and make sure that the code will only target specific elements so that it will not create any conflict and issues with other button elements in your site.

Please note that custom coding is beyond the scope of our support. You will have to maintain any custom coding to make sure that it will still work after any updates or does not create any issues or incompatibility in the future.

Best Regards.
