1 $ (' #top '). Click (function() {2   $ (document.body). Animate ({scrolltop:0}, ); 3   return false ; 4 })

Here are two parameters, one is scrolltop,0 to scroll to the top of the 0 position, 10 is to scroll to the top 10px position

800 is the speed of scrolling, the smaller the faster, too fast too slow is not good, personal test 800 is a more eclectic number
