Scroll to href with script

Question

I have this code.

$('a').click(function(){
    $('html, body').animate({
        scrollTop: $( $.attr(this, 'href') ).offset().top
    }, 500);
    return false;
});

How can I make this script with a super smooth easing effect?

Answer 1

Save the href attribute before calling animate, otherwise the scope of this is incorrect.

$(function() {
  $('a').click(function() {
    var href = $(this).attr("href");
    $('html, body').animate({
      scrollTop: $(href).offset().top
    }, 500);
    return false;
  });
});

p {
  height: 2000px;
}
#inner {
  height: 200px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<a href="#inner">Go to #inner</a>
