I think you are looking for one of these:

document.getElementById('SelectId').options.length;

OR

document.getElementById('SelectId').selectedIndex;

Try something like:

/**
 * Alerts out the selected item values of a select box
 *
 * @author sos
 * @param {HTMLFormElement} frm The reference to the form element
 * @param {String} name The name of the select box
 */
function show(frm, name) {
  var selOpts = frm.elements[name].options;
  for(var i = 0, max = selOpts.length; i < max; ++i) {
    if(selOpts[i].selected) {
      alert("Selected Item: " + selOpts[i].value);
    }
  }
}
