How to implement automatic scrolling to the top of the page with jQuery_jquery

The example in this article describes how jQuery can automatically scroll to the top of the page. Share it with everyone for your reference. The specific implementation method is as follows:

$(".scroll").click(function(event)
{
  //prevent the default action for the click event
  event.preventDefault();
  //get the full url - like mysitecom/index.htm#home
  var full_url = this.href;
  //split the url by # and get the anchor target 
  //name - home in mysitecom/index.htm#home
  var parts = full_url.split("#");
  var trgt = parts[1];
  //get the top offset of the target anchor
  var target_offset = $("#"+trgt).offset();
  var target_top = target_offset.top;
  //goto that anchor by setting the body scroll top to anchor top
  $('html, body').animate({scrollTop:target_top}, 500);
});​

I hope this article will be helpful to everyone’s jQuery programming.
