Smooth scroll

This code sample will allow you to scroll the view to a predefined vertical offset (in pixels) or the beginning of a specified id.

function smoothScroll(y) {
if (typeof y === "string") {y=document.querySelector("#"+y);}
if(typeof y === "object") {y=y.offsetTop;}
for (var i = 0; i < y; i++) {
setTimeout(function () {
document.body.scrollTop = arguments[0] * 2;
}, i * 2, i);


- Call smoothScroll(y);

- y can be a number (offset from top in pixels) or a string identifying an id.
