How to scroll to top using JQuery and Material-Design-Lite

Question

I've been using Material-Design-Lite in my website and I'm also using JQuery to display a button that scrolls to top. But they are not working together. With Material-Design-Lite installed, the button does nothing on click.

<div class='back-to-top'>
  <a class='hvr-icon-spin' href='#'/>
</div>

<script>
  $(window).scroll(function() {
    if($(this).scrollTop() &gt; 200) {
      $(&#39;#back-to-top&#39;).fadeIn();
        } else {
        $(&#39;#back-to-top&#39;).fadeOut();
        }
        });
      $(&#39;#back-to-top&#39;).hide().click(function() {
        $(&#39;html, body&#39;).animate({scrollTop:0}, 600);
        return false;
        });
</script>

Is there any alternative way to solve it? I've tried not using JQyery, but it also didn't work. The website I'm trying to use it is here.

Answer 1

This might happen due to fixed position of your main container, header. And material design uses overflow in mdl container. So use this code to scroll top:

$(".mdl-layout__content").animate({scrollTop:0}, 500, "slow");

Answer 2

您可以尝试使用

$('.mdl-layout__content').animate({scrollTop:0}, 'slow');

Answer 3

You can check with the below link.

http://jsfiddle.net/6qrQF/88/

 jQuery(document).ready(function() {
  //set the link
  jQuery('#top-link').topLink({
    min: 500,
    fadeSpeed: 100
  });
  //smoothscroll
  jQuery('#top-link').click(function(r) {    
    jQuery("html, body").animate({ scrollTop: 0 }, 300);
  });
});

Answer 4

对我来说，它与：

$('.mdl-layout').animate({scrollTop:0}, 'slow');
