Auto-save browser forms with localstorage

We all know how annoying it is to be half-way through filling in a web form, only to accidentally close the window or hit the back button. Well, with the advent of localStorage, the solution is quite simple: just get the browser to do it!

A jQuery plugin, called sisyphus, has been in development by Alexander Kaupanin since October 2011; he has been making many minor fixes and improvements along the way. To use it, download the plugin itself to your own web space: sisyphus.min.js and include these lines in your <head> section:

<script src="" type="text/javascript"></script>
<script type="text/javascript" src="sisyphus.min.js"></script>
<script type="text/javascript">
	$('form').sisyphus({timeout: 5});

You'll need to modify the src attribute of sisyphus.min.js, depending on where you put it.

The example above saves all forms on the page every 5 seconds. There are several simple customisations - see for more options.
