jQuery web page right ad follows scrolling code sharing_jquery

Both methods are shared with everyone, hoping to inspire everyone's learning.

Method 1:

<script type="text/javascript">// <![CDATA[ 
$.fn.smartFloat = function() { 
  var position = function(element) { 
    var top = element.position().top, pos = element.css("position"); 
    $(window).scroll(function() { 
      var scrolls = $(this).scrollTop(); 
      if (scrolls > top) { 
        if (window.XMLHttpRequest) { 
          element.css({ 
            position: "fixed", 
            top: "10px" 
          }); 
        } else { 
          element.css({ 
            top: scrolls 
          }); 
        } 
      }else { 
        element.css({ 
          position: pos, 
          top: top 
        }); 
      } 
    }); 
  }; 
  return $(this).each(function() { 
    position($(this)); 
  }); 
}; 
 
//绑定 
$("#float").smartFloat(); 
// ]]></script> 

Method 2:

/*页面智能层浮动*/ 
jQuery(document).ready(function($){ 
  var $sidebar = $(".float"), 
  $window = $(window), 
  offset = $sidebar.offset(), 
  topPadding = 20; 
  $window.scroll(function() { 
    if ($window.scrollTop() > offset.top) { 
      $sidebar.stop().animate({ 
        marginTop: $window.scrollTop() - offset.top + topPadding 
      }); 
    } else { 
      $sidebar.stop().animate({ 
        marginTop: 0 
      }); 
    } 
  }); 
}); 
<div id="float" class="float"> 
<h3 id="博主推荐">博主推荐</h3>

</div>

The above is how the ads on the right side of the jQuery web page follow the scrolling, imitating the ads on the right side of the WordPress page that follow the scrolling. I hope it will be helpful to everyone's learning.
