Getting value from combobox

Question

I have a html combo/select. When the user selects a element, I want to populate textboxcontrol from it. How to do it.

Answer 1

HTML:

<select id="combobox">
     <option value="">Pick one</option>
     <option value="1">1</option>
     <option value="2">2</option>
     <option value="3">3</option>
     <option value="4">4</option>
</select>
<input id="textbox" type="text" />

Javascript (assumes jQuery):

$('#combobox').change( function(){
     $('#textbox').val( $(this).val() );
}).click( function(){
     $('#textbox').val( $(this).val() );
});
