Here is my code. Why it doesn't work? 

<Script> 
   $('#colorselector').change(function() {
        $('.colors').hide();
        $('#' + $(this).val()).show();
 });
</Script>
<Select id="colorselector">
   <option value="red">Red</option>
   <option value="yellow">Yellow</option>
   <option value="blue">Blue</option>
</Select>
<div id="red" class="colors" style="display:none"> .... </div>
<div id="yellow" class="colors" style="display:none"> ... </div>
<div id="blue" class="colors" style="display:none"> ... </div>
jquery html html-select

You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});
