Question about "auto saving" PHP, jQuery

[Joveice]

Hi.

 

I want to know how those auto saving stuff works, etc some sites I go on and I change my "group" and when I press another thing in the list and refresh the page that thing is now saved in the database and I never hit a submit button on the form (not talking about using cookies to track preferences)

So how is this normaly done? and is it a way to do it in jQuery?

You can add "onchange" and similar to form elements to trigger a javascript function which can then send a request to the server adding the information about the change to the database.

 

For example:

<h3>Do you like garlic bread?</h3>
<select onchange="sendToServer()">
	<option value="It's ok">It's ok
    <option value="Of course!">Of course!
    <option value="You'd be a fool to not">You'd be a fool to not
    <option value="Puppies are pretty swell">Puppies are pretty swell
</select>

 

Whenever someone selects a new option it triggers the sendToServer function
