Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

scrollIntoViewIfNeeded 4 everyone!!!

This gist provides a simple JavaScript implementation of the non-standard WebKit method scrollIntoViewIfNeeded that can be called on DOM elements.

Usage

Just use the code in index.js in your app or website. You can see usage in the test page test.html.

The parent element will only scroll if the element being called is out of the view. The boolean can force the element to be centered in the scrolling area.

// comments welcome, there may be better ways to do this!

function supportsSVG(){
 return !!('createElementNS' in document &&
   document.createElementNS('http://www.w3.org/2000/svg','svg').createSVGRect)
