Rails4: How can I change a display position after clicking a link?

Question

I use will_paginate at the bottom of the page.
Although the page is displayed after clicking the page number, the position of a scroll remains the same (bottom of the page).
I'd like to display the top of the page.

How can I change the display position?

\view\calendars\index.html.erb

...
<%= will_paginate @calendar %>

Answer 1

You can use javascript for this

$("html, body").animate({ scrollTop: 0 }, "slow");
