Implementation of the function of returning the page to the top, and implementation of returning the page to the top

This is a small function. The implementation of jQuery is very simple, that is, the animate () method, which is specially recorded.

First, paste the function code at the top of the returned result:

Method 1:

1 $(function(){2     $("#toTop").click(function(){3         $("html").animate({"scrollTop": "0px"},100); //IE,FF4         $("body").animate({"scrollTop": "0px"},100); //Webkit5         });6     })

Method 2:

function toTop(){        window.scroll(0,0);        }

Method 3:

<a href="#">Back to top</a>
