Javascript + HTML5 localstorage [closed]

Here's a crash crash course I found very useful. It explains a bunch of HTML5 concepts, including localStorage, video tag, offline websites, forms, locations, canvas, and more.

http://diveintohtml5.org/storage.html

There is the offical documentation:

http://dev.w3.org/html5/webstorage/

For a quick demo with code: http://html5demos.com/storage also more html5 demos at the root of that site.

Note there are also things like the YUI 2 Storage Utility which abstract the storage for you (HTML 5, Google Gears, SWF) depending on what the browser supports:

The Storage Utility provides a mechanism for storing significant amounts of textual data, client-side, whether or not your browsers supports the proposed HTML 5 Storage specification.

No personal experience but I did come across this link today: http://www.w3avenue.com/2010/05/07/html5-unleashed-tips-tricks-and-techniques/

Which links to this: http://net.tutsplus.com/tutorials/html-css-techniques/quick-tip-learning-about-html5-local-storage/

Have fun!

This small tutorial/code-snippet helped me to get started.

I would recommend one of the other questions asked here about how to store objects in localStorage. It helped me a lot as I am implementing a code editor that can store multiple files and last state of the user.

The stackoverflow question
Both answers posted are very valuable.

Some things to take into consideration:

• When do you store data, after each key pressed or after some other specific action/event?
• Use a temporary Javascript data structure or only interact with localStorage directly?

Store Data

//Syntax 
localStorage.setItem(Key,Value);
