Hello. This one is a tiny library that helps you to save entered values of HTML elements. It is actually pretty lame.
This helps to not lose form values on tab close/page reload. If you need something super-stable -- write your own.
All you have to do is add the script in your html file:
<script type="text/javascript" src="preserve.js"></script>
And then add the "preserve" property to any html element:
<input type="checkbox" id="checkit" preserve/>
This will save element value every time it changes, in a localstorage.
Values are saved in an identifier which, if no value for "preserve" attribute is set, is generated, url- and elementID-dependant. You can alter this by specifying the value for preserve attribute
<input type="checkbox" id="checkit" preserve="check_it"/>
By default the values are saved by a key formed from current url + hash symbol + id or name of element. (Name is used if id is empty). Say, for this:
<input type="checkbox" id="checkit" preserve/>
The value, on http://localhost/preserve will be saved in a key called localhost/preserve#checkit. This means that, say,
on http://localhost/preserve?mode=gallery page it will not be preserved, even if input has same id.
- Support for select multiple
LocalStorage is limited to 5MB. So maybe consider not using this for large input fields etc.
