okay, have given, can guess need option's text.

function getselectedtext(elementid) {     var elt = document.getelementbyid(elementid);      if (elt.selectedindex == -1)         return null;      return elt.options[elt.selectedindex].text; } 

use way:

var text = getselectedtext('selectid');

or derek suggested, can have in 1 line too:

var text = elementid.queryselector("option:checked").innertext 

note: works in modern browsers.
