Show/hide content with specific class using jquery

Question

I'am new to jquery and maybe this is a stupid question but I have searched for an answer just about everywhere without finding one. So, here we go:

I want to show different content depending on what option I select in a drop down form. As I have learnt here on StackOverflow, you ca use the change function to do this:

Example:

<script type="text/javascript">

$(document).ready(function() {
$('#myselector').change(function(){
  $('.statecontent').hide();
  $('#' + $(this).val()).show();    
});
});

</script>

 <select id="myselector">
 <option value="state1"></option><br />
 <option value="state2"></option><br />
 <option value="state3"></option><br />
 </select>

<div id="state1" class="statecontent">State1 Specific Page Content Goes here</div><br     />
<div id="state2" class="statecontent">State2 Specific Page Content Goes here</div><br />
<div id="state3" class="statecontent">State3 Specific Page Content Goes here</div><br />

This code will alove me to show content thats inside the different divs depending on what 'state' I choose in the drop down. But how do I connect the values of the drop down to a specific class instead of an id. The problem is of course that I want to show several divs that share a common class when i select a state in the drop down.

I would very much appreciate if anyone could point me in the right direction.

Read a jQuery doc about selectors. $("#someId") selects the element havig someId as id. $(".someClass") selects the elements having someClass as class. It uses the CSS3 notation. That's the heart of jQuery.
