Let me get this straight, you want to update the values of your <select><options> using values you retrieve from a database -- based on what option your user selects from that <select> field initially? Is that correct?

If so, you might expand upon this code snippet to change the values of your select menu.
If you have the same number of new options as the original then it's easy, if you need to add or remove options depending on the results you get back you can also do that with DOM methods, or you can construct an entire new <select> input element with the new options and swap out the old with the new using either DOM methods or innerHTML method.

function retrieveOption () {
  var state = document.getElementById('state');
  for ( var i = 0; i < state.length; i ++ ) {
    if ( state[i].selected ) {
      // grab the new values here
      // example of updating one <option> value
      state[i].value = 'pizza';
      state[i].firstChild.nodeValue = 'Pizza';
    }
  }
}

Please clarify your problem some more if you need more help.

Thanks
