Savy

an ultra-light jQuery plugin that automatically saves form values in the client side (using HTML5 localStorage) and restore them on your next visit. A great solution to prevent data loss in case the browser is refreshed or the page is suddenly closed.

Supported elements:

input (text/number/checkbox/radio)
select (single/multiple)
textarea

How to use:

Include jquery and Savy JS files

<script src="jquery.js"></script>
<script src="savy.min.js"></script>

Create the following HTML element (each element must have a unique ID)

<form action="foo.php">
  First name:<br>
  <input id="fname" type="text" class="auto-save" name="firstname" value="Mickey">
  <br>
  Last name:<br>
  <input id="lname" type="text" class="auto-save" name="lastname" value="Mouse">
</form>

initialize Savy

$('.auto-save').savy('load');

// you can pass a function to be called when savy is finished loading.
$('.auto-save').savy('load',function(){
 console.log("All data from savy are loaded");
});

destroy Savy

$('.auto-save').savy('destroy');

// you can pass a function to be called when savy is destroyed.
$('.auto-save').savy('destroy',function(){
 console.log("All data from savy are destroyed");
});

TODO:

~~Support for single and multiple select~~
~~Support for checkbox and radiobutton~~
~~callback when savy data is loaded/destroyed~~
~~add support for saving auto-selected value(s) in single and multiple select~~
~~add support for saving values filled by the browser's Autocomplete~~
add retention period for a value
destroy a single value (currently: destroy will delete all Savy's data)
reset user input when Savy is destroyed (currently: inputs will still contain their values)

Compatibility:
