SCALABLE: Save form data to localStorage and auto-complete on refresh
// With the help of Jeremy Keith, I was able to create a fully scalable code sample that you can copy-paste into your project.
// It will save the user input value on blur, this includes radio buttons, checkboxes and date inputs besides regular text/number inputs.
// The only condition is that you give the form element on your page a data-attribute of data-form-topic="foo".
// This code snippet saves the data-attribute as the key to the localStorage, and the value of it will be an object with key/value pairs of the respective inputs name and value.
// Please refer to this gist somewhere in your code if you use it :)
// Happy coding!
// VARIABLE DECLARATIONS
// objects

WARNING!
You probably shouldn't use this technique since images never show up
if the script isn't loaded for one reason or another. Some reasons:
- The content is viewed using a RSS reader
- The content is viewed with a read-it-later service
- The user has a flaky connection (hotel wifi, Dutch train, etc)

Anchor-include Pattern
/*
* anchor-include pattern for already-functional links that work as a client-side include
* Copyright 2011, Scott Jehl, scottjehl.com
* Dual licensed under the MIT
* Idea from Scott Gonzalez
* to use, place attributes on an already-functional anchor pointing to content
* that should either replace, or insert before or after that anchor
* after the page has loaded
* Replace: <a href="..." data-replace="articles/latest/fragment">Latest Articles</a>
* Before: <a href="..." data-before="articles/latest/fragment">Latest Articles</a>
