Sets a function that performs a function scroll bar auto-drag, and the page jumps to the location of the specified DOM element.

The implementation is simple, first introduce the Animatescroll.js file (to introduce jquery first), and then

$ (' #id '). Animatescroll ();

You can adjust the location of the page to the specified DOM element.

For convenience you can write a function that passes in the ID of the DOM element

function Jumpto (ID) {    $ ("#" +ID). Animatescroll ();

Attached Animatescroll.js

/*method of Use: $ ("#id"). Animatescroll (); can be transferred to the location of the specified DOM on the page*/(function($) {$.fn.animatescroll=function(options) {//Fetches Options        varopts =$.extend ({},$.fn.animatescroll.defaults,options); //Get the distance of particular ID or class from top        varoffset = This.
