Hello, im starting study Jquery and im trying to do a basic example.
I have a html file index.html and other functions.js.
In the index.html i have some menus, content and text.
In the functions.js i have this function above.
But when i click in my link "footer-top" is not working.
What should be the problem?


    <section id="footer1">
           <a href="#" class="footer-top">Go To Top</a>
    </section>


    $(document).ready(function() {
       $('.top').click(function(){
       $('html,body').animate({ scrollTop: 0 }, 'slow');
        })
     });

Solution 2

Adding to Peter Leow's solution, you should also use event.preventDefault()

JavaScript

$(document).ready(function() {
   $('.footer-top').click(function(event){
      event.preventDefault();
      $('html,body').animate({ scrollTop: 0 }, 'slow');
   });
});

You should use this because the link has a href of #, which will make the browser leap to the top of the page without animation. event.preventDefault() cancelles the default behaviour.

Good info craig, but anyhow we should use $('.footer-top') to select the anchor element.

Oops! Forgot to change it when I copy/pasted. I'd already noticed Peter's solution :-)
